Use of hydroxamic acids for stabilizing cosmetic and / or dermatological preparations

The present invention relates to cosmetic or dermatological preparations containing active ingredients for the protection of the sensitive skin from irritation and to the use of such active ingredients and combinations of such active ingredients in the field of cosmetic and dermatological skin care. In an advantageous embodiment, the present invention relates to an application which makes it possible to increase the stability of emulsions, gels, aqueous formulations or fat formulations.

The outermost layer of the epidermis, the stratum corneum (horny layer), is of particular importance as an important barrier layer, inter alia. for protection against environmental influences and dehydration. The horny layer is constantly worn in contact with the environment and must therefore be renewed continuously.

A skin model widely used today in the art understands the stratum corneum as a two-component system, similar to a brick wall (brick-mortar model). In this model, the corneocytes (horny cells) correspond to the bricks, the complex composite lipid membrane in the intercellular spaces corresponds to the mortar.

In addition to their barrier effect against external chemical and physical influences, the epidermal lipids also contribute to the cohesion of the horny layer and have an influence on the skin smoothness. In contrast to the sebaceous gland lipids, which do not form a closed film on the skin, the epidermal lipids are distributed over the entire horny layer.

The extremely complex interaction of the moisture-binding substances and the lipids of the upper skin layers is very important for the regulation of skin moisture. Therefore Cosmetics usually contain, in addition to balanced lipid blends and water, water-binding substances.

In addition to the chemical composition, however, the physical behavior of these substances is important. Therefore, the development of highly biocompatible emulsifiers or surfactants with liquid crystalline properties is desirable. Products formulated in this way support the liquid-crystalline organization of the intercellular lipids of the stratum corneum and thus improve the barrier properties of the horny layer. It is particularly advantageous if their molecular constituents consist of substances naturally occurring in the epidermis.

Cosmetic skin care is understood primarily to strengthen or restore the natural function of the skin as a barrier to environmental influences (e.g., dirt, chemicals, microorganisms) and to the loss of endogenous substances (e.g., water, natural fats, electrolyte).

If this function is disturbed, it may lead to increased absorption of toxic or allergenic substances or the infestation of microorganisms and as a result to toxic or allergic skin reactions.

The aim of skin care is also to compensate for the daily loss of fat and water loss of the skin. This is especially important when the natural regeneration capacity is insufficient. In addition, skin care products to protect against environmental influences, especially from the sun and wind, and delay the aging of the skin.

Medical topical compositions typically contain one or more drugs in effective concentration. For the sake of simplicity, reference is made to the clear distinction between cosmetic and medical use and corresponding products to the statutory provisions of the Federal Republic of Germany (for example, Cosmetics Regulation, Food and Medicines Act).

Common cosmetic dosage forms are emulsions, ie metastable two- or multi-phase systems in which the individual phases are in the liquid state. The most common emulsions are O / W and W / O emulsions. Rarer forms of administration are multiple emulsions, ie those which are present in the droplets of the dispersed (or disperse) continuous) phase in turn contain droplets of a further dispersed phase, for example W / O / W emulsions and O / W / O emulsions.

In order to ensure the metastability of emulsions, surface-active substances, ie emulsifiers, are generally required.

In itself, the use of the usual cosmetic emulsifiers is completely harmless. Nevertheless, emulsifiers, such as any chemical substance, may in individual cases cause allergic or hypersensitivity reactions of the user.

It is known, for example, that in certain particularly sensitive persons certain photodermatoses are triggered by certain emulsifiers and the simultaneous action of sunlight.

It is possible to produce emulsifier-free preparations which, for example, have oil droplets dispersed in an aqueous phase, similar to an O / W emulsion. A prerequisite for this may be that the continuous aqueous phase has a gel skeleton which stabilizes the dispersed phase and other circumstances more. Such systems are sometimes called hydrodispersions or oleodispersions, whichever is the disperse and which is the continuous phase.

However, it is neither necessary nor possible to dispense with emulsifiers for cosmetic galenics, especially since there is a certain selection of particularly mild emulsifiers. However, there is a lack of the state of the art in a satisfactorily large variety of such emulsifiers, which would then significantly widen the range of applications according to mild and skin-friendly cosmetic preparations.

Thus, it was an object of the present invention to provide cosmetic or dermatological preparations with outstanding skin-care properties.

A disadvantage in particular of O / W emulsions is often their lack of stability towards higher electrolyte concentrations, which manifests itself in phase separation. While this may occasionally cause problems with W / O emulsions, it is not nearly as prominent here as in O / W systems. Although this can often be done by appropriate To some extent, choosing the emulsifier system will help, but there are just as many other disadvantages.

On the other hand, it is often desirable to use certain electrolyte in order to utilize their other physical, chemical or physiological properties.

Furthermore, increased heavy metal concentrations - production-related due to production in steel containers, agitators, lines, etc. - significantly reduce the stability of cosmetic preparations. By complexing of interfering metals such as Mn, Fe, Cu and others, for example, unwanted chemical reactions in cosmetic or dermatological preparations can be prevented.

Complexing agents, in particular chelators, form complexes with metal atoms, which in the presence of one or more polybasic complexing agents, ie chelators, represent metallacycles. Chelates are compounds in which a single ligand occupies more than one coordination site on a central atom. In this case, normally stretched compounds are closed by complex formation via a metal atom or ion into rings. The number of bound ligands depends on the coordination number of the central metal. The prerequisite for chelation is that the metal-reactive compound contain two or more atomic groups acting as electron donors.

A disadvantage of many chelators is that they are difficult to biodegrade, almost inevitably be registered in the ecological water cycle. By solubilization of precipitated or sediment-bound - and thereby relatively harmless - heavy metal ions, they can in the worst case contribute to their reactivation.

A further object of the present invention was therefore to discover solutions to cosmetic or dermatological emulsions, in particular O / W emulsions, which are stable to increased electrolyte concentrations or elevated ionic strengths or heavy metal ions.

Common, and especially in recent times increasingly widespread cosmetic and dermatological formulations are gels. In the technical sense, gels are understood to mean relatively dimensionally stable, easily deformable disperse systems of at least two components, which as a rule consist of a (mostly solid) colloid-divided substance of long-chain molecular groupings (eg gelatin, silica, polysaccharides) as a scaffold former and a liquid dispersant (eg water) exist. The colloidally divided substance is often referred to as a thickener or gelling agent. It forms a spatial network in the dispersion medium, whereby individual colloidal particles can be more or less strongly linked to each other via electrostatic interaction. The dispersant surrounding the network is characterized by electrostatic affinity for the gelling agent, ie, a predominately polar (especially hydrophilic) gelling agent preferably gels a polar dispersing agent (especially: water), whereas a predominantly nonpolar gelling agent preferably gels non-polar dispersing agent.

Strong electrostatic interactions, which are realized, for example, in hydrogen bonds between gelling agent and dispersant, but also between each other among dispersant molecules, can lead to strong crosslinking of the dispersant. Hydrogels can consist of almost 100% water (besides, for example, about 0.2-1.0% of a gelling agent) and have a very firm consistency. The water content is present in ice-like structural elements, so that gels therefore their name origin [from Latin "gelatum" = "Frozen" on the alchemical expression "gelatina" (16th century) for nhdt "gelatin"] quite well.

In cosmetic and pharmaceutical galenics, lipogels and oleogels (from waxes, fats and fatty oils) and carbogels (from paraffin or petrolatum) are also familiar. In practice, one differentiates between oleogels, which are practically anhydrous, hydrogels, which are virtually free of fat. Mostly gels are transparent. In cosmetic or pharmaceutical galenics gels are usually characterized by a semi-solid, often flowable consistency.

Furthermore, so-called surfactant gels are common preparations of the prior art. This refers to systems which, in addition to water, have a high concentration of emulsifiers, typically more than about 25% by weight, based on the total composition. Solubilized in these surfactant gels, technically also called "surfactant gels", oil components, microemulsion gels are obtained, which are also known as "ringing By adding nonionic emulsifiers, for example alkylpolyglycosides, cosmetically elegant microemulsion gels can be obtained.

Numerous cosmetic and dermatological active ingredients are known, including water-soluble - which are therefore primarily in the water phase of an emulsion - and oil-soluble - which are therefore primarily in the oil phase of an emulsion.

The log P value indicates the logarithmic coefficient of the octanoi / water K ₀ w distribution coefficient and is a measure of how the relationship between lipopoly (fat solubility) and hydrophilicity (water solubility) of a substance is. It serves as a model estimation in which phase (oil or water) the substance dissolves or accumulates preferentially.

Accordingly, the log P is positive for lipophilic substances and negative for hydrophilic substances

Thus, a log P value of three means that the active ingredient would be distributed in an octanoi / water mixture in the ratio 1000: 1. So enriched by a factor of 1000 higher in the oil phase. The same applies to substances that have only a very low solubility in water. These substances are - if they are formulated crystal-free - to find predominantly in the lipid phase.

As active substances, which are predominantly in the oil phase, are understood in the context of this application substances that

 a) have a log P value> 2 or

 b) have a water solubility <2.5 g / L.

 In plant extracts, this means that 0.25% solutions can not be solved clearly.

Cosmetic and pharmaceutical agents are often, but not always, stable against environmental influences. Thus, numerous instabilities to oxygen - or more generally redox processes - and UV light, but also against heat and other known. Among the drugs that are known to be sensitive to such processes include

It has surprisingly been found, and therein lies the solution of these objects, that the use of one or more physiologically acceptable hydroxamic acids for achieving or increasing the stability of cosmetic preparations which in the form of OW, W / O, W / O / W, or O / W / O emulsions, hydrodispersions, oleodispersions, hydrogels or oleogels are available to overcome the disadvantages of the prior art.

The term "achieving or increasing the stability" means that a corresponding formulation, which has a content of one or more physiologically acceptable hydroxamic acids, exhibits a higher stability than a corresponding formulation without hydroxamic acid.

In this case, compared to a formulation which has a content of one or more physiologically acceptable hydroxamic acids, with one in which the proportion by weight of one or more physiologically acceptable hydroxamic acids has been replaced by a corresponding weight fraction of water or the main oil component of the preparation.

The term "stability" is intended in this context to mean that the product with one or more physiologically acceptable hydroxamic acids, if it is an emulsion, a hydrodispersion, an oleodispersion, a hydrogel or an oleogel, a longer time and / or at higher Protected against phase separation is a product without hydroxamic acid.

The term "stability" may also mean that the product with one or more physiologically acceptable hydroxamic acids, if it contains a dye, this dye is protected for a longer time and / or at higher temperatures and / or at a higher dose of light against chemical decomposition The term "stability" may also mean that the product with one or more physiologically acceptable hydroxamic acids, if it contains a perfume component or a cosmetic fragrance component, this drug for a longer time and / or at higher temperatures and / or is protected against chemical decomposition at a higher dose of light than a product without hydroxamic acid. The term "stability" may also mean that the product with one or more physiologically acceptable hydroxamic acids, if it contains a cosmetic or dermatological active ingredient, this active ingredient for a longer time and / or at higher temperatures and / or at a higher dose of light against chemical decomposition is protected as a product without hydroxamic acid.

The term "stability" may also mean that the product containing one or more physiologically acceptable hydroxamic acids, when containing polyvalent metal ions, protects the product against chemical degradation for a longer time and / or at higher temperatures and / or at a higher dose of light a product without hydroxamic acid.

It is believed that the hydroxamic acids exhibit a beneficial chelating property in cosmetic or dermatological preparations. Therefore, the use according to the invention of one or more physiologically acceptable hydroxamic acids is also suitable as chelating agents for divalent or polyvalent metal ions in cosmetic or dermatological preparations.

Furthermore, it was not foreseeable for the skilled person that the preparations according to the invention would have higher stability and would be distinguished by better biocompatibility than the preparations of the prior art.

Octanohydroxamic acid, also called caprylohydroxamic acid, is characterized by the following structure.

O

OH

It is a known active ingredient for the preservation of cosmetic preparations (eg WO 2009/070736 A1). Advantageous embodiment of the present invention is when the octanohydroxamic acid is chosen as the hydroxamic acid.

Preparations according to the invention are advantageously characterized by a content of 0.01 to 10 wt .-%, in particular 0.05 to 3.0 wt .-%, of one or more physiologically acceptable hydroxamic acids, in particular octanohydroxamic acid, in each case based on the total weight of the composition.

It is particularly advantageous for the purposes of the present invention, the content of conventional complexing agents, such as those selected from the group ethylenediaminetetraacetic acid (EDTA) and their anions, nitrilotriacetic acid (NTA) and their anions, hydroxyethylenediamino-triacetic acid (HOEDTA) and their anions, diethyleneaminopentaacetic acid ( DPTA) and their anions, trans-1, 2-diaminocyclohexanetetraacetic acid (CDTA) and their anions to keep low or to dispense entirely. In any case, a content of about 0.5% by weight, based on the total weight of the cosmetic preparations, of such complexing agents should preferably not be exceeded.

The preparation of preparations according to the invention is carried out according to the usual rules familiar to the person skilled in the art.

It is possible and advantageous to add the hydroxamic acid or the hydroxamic acids, in particular the octanohydroxamic acid, to the other constituents at any desired point in time of the preparation.

The cosmetic preparations according to the invention may contain cosmetic adjuvants such as are commonly used in such preparations, e.g. Preservatives, bactericides, deodorizing substances, antiperspirants, insect repellents, vitamins, antifoaming agents, dyes, coloring pigments, thickeners, emollients, moisturizing and / or moisturizing substances, fats, oils, waxes or other common ingredients a cosmetic formulation such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicone derivatives.

Advantageously, preparations according to the invention may also contain substances which absorb UV radiation in the UVB range, the total amount of the filter substances For example, 0.1 wt .-% to 30 wt .-%, preferably 0.5 to 10 wt .-%, in particular 1, 0 to 6.0 wt .-%, based on the total weight of the preparations to cosmetic preparations to provide the hair or the skin against the entire range of ultraviolet radiation. They can also serve as a sunscreen for hair.

If the preparations according to the invention contain UVB filter substances, these may be oil-soluble or water-soluble. Advantageously oil-soluble UVB filters according to the invention are, for example:

 3-benzylidene camphor derivatives, preferably 3- (4-methylbenzylidene) camphor, 3-benzylidene camphor;

 4-aminobenzoic acid derivatives, preferably (2- ethylhexyl) 4- (dimethylamino) benzoate, 4- (dimethylamino) benzoic acid amyl ester;

 Esters of cinnamic acid, preferably 4-methoxycinnamic acid (2-ethylhexyl) ester, 4-methoxycinnamic acid isopentyl ester;

 Esters of salicylic acid, preferably 2-ethylhexyl salicylate, 4-isopropylbenzyl salicylate, homomenthyl salicylate,

 2,4,6-Trianilino- (p-carbo-2'-ethyl-1'-hexyloxy) -1,3,5-triazine.

Advantageous water-soluble UVB filters are, for example:

 Salts of 2-phenylbenzimidazole-5-sulfonic acid, such as its sodium, potassium or triethanolammonium salt, and the sulfonic acid itself;

 Sulfonic acid derivatives of benzophenones, preferably 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and its salts;

Sulfonic acid derivatives of the 3-benzylidene camphor, such as, for example, 4- (2-oxo-3-bomylidene-methyl) benzenesulfonic acid, 2-methyl-5- (2-oxo-3-bomylidenemethyl) sulfonic acid and its salts, and di (2-oxo-10-sulfo-3-bomylidenemethyl) benzene and its salts (the debasing 10-sulfato compounds, for example the corresponding sodium, potassium or triethanolammonium salt), also as benzene-1, 4- di (2-oxo-3-boronylidenemethyl-10-sulfonic acid The list of said UVB filters which can be used according to the invention should of course not be limiting.

It may also be advantageous to use UVA filters that are commonly included in cosmetic preparations. These substances are preferably derivatives of dibenzoylmethane, in particular 1- (4'-tert-butylphenyl) -3- (4'-methoxyphenyl) propane-1, 3-dione and 1-phenyl-3- ( 4'-isopropylphenyl) propane-1,3-dione. The amounts used for the UVB combination can be used.

According to the invention, cosmetic and dermatological preparations advantageously also contain inorganic pigments based on metal oxides and / or other sparingly soluble or insoluble metal compounds, in particular the oxides of titanium (TiO ₂ ), zinc (ZnO), iron (eg Fe ₂ O ₃ ), zirconium (Zr0 ₂ ), silicon (Si0 ₂ ), manganese (eg MnO), aluminum (Al ₂ 0 ₃ ), cerium (eg Ce ₂ 0 ₃ ), mixed oxides of the corresponding metals and mixtures of such oxides. Particular preference is given to pigments based on TiO ₂ .

It is particularly advantageous within the meaning of the present invention, although not mandatory, when the inorganic pigments are in hydrophobic form, that is, that they are superficially treated to repel water. This surface treatment may consist in providing the pigments with a thin hydrophobic layer according to methods known per se.

One such method is, for example, that the hydrophobic surface layer is generated according to a reaction according to n Ti0 ₂ + m (RO) ₃ Si-R '-> n Ti0 ₂ (surface), where n and m are stoichiometric parameters to be used as desired , R and R 'are the desired organic radicals. For example, in analogy to DE-OS 33 14 742 illustrated hydrophobized pigments are advantageous.

Advantageous Ti0 ₂ pigments are available, for example, under the trade names MT 100 T from the company TAYCA, furthermore M 160 from the company Kemira and T 805 from the company Degussa. Preparations according to the invention can also contain anionic, nonionic and / or amphoteric surfactants, especially if crystalline or microcrystalline solids, for example inorganic micropigments, are to be incorporated into the preparations according to the invention. Surfactants are amphiphilic substances that can dissolve organic, nonpolar substances in water.

The hydrophilic moieties of a surfactant molecule are usually polar functional groups, for example -COO ^" , -OSO ₃ ^2" , -SO ₃ ^" , while the hydrophobic moieties usually represent nonpolar hydrocarbon radicals, surfactants generally being sorted and charged of the hydrophilic part of the molecule, whereby four groups can be distinguished:

Anionic surfactants,

 Cationic surfactants,

 • amphoteric surfactants and

 • nonionic surfactants.

Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution, they form negatively charged organic ions in an acidic or neutral medium. Cationic surfactants are almost exclusively characterized by the presence of a quaternary ammonium group. In aqueous solution they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and behave accordingly in aqueous solution depending on the pH as anionic or cationic surfactants. They have a positive charge in a strongly acidic environment and a negative charge in an alkaline environment. In the neutral pH range, however, they are zwitterionic, as the following example is intended to illustrate:

RNH ₂ ⁺ CH ₂ CH ₂ COOH X (at pH = 2) X ^" = any anion, eg CI ^"

RNH ₂ ⁺ CH ₂ CH ₂ COO- (at pH = 7)

RNHCH ₂ CH ₂ COO-B ⁺ (at pH = 12) B ⁺ = any cation, eg Na ⁺ Typical of non-ionic surfactants are polyether chains. Non-ionic surfactants do not form ions in an aqueous medium.

Incidentally, it has surprisingly been found that the scent impression of a cosmetic preparation is markedly improved by the addition of one or more hydroxamic acids, in particular octanohydroxamic acid, in excess of such a preparation which does not contain hydroxamic acid.

This is all the more surprising since, in particular, octanohydroxamic acid and its derivatives and, in particular, octanohydroxamic acid-containing skin care products can form a side odor which is perceived as unpleasant for the user.

Precisely when octanohydroxamic acid has been formulated as a constituent of a body lotion and the first volatile perfume constituents have evaporated, an acidic, chlorous side odor attributable to the octanohydroxamic acid may result.

As an advantageous embodiment of the present invention, therefore, combinations of substances from one or more hydroxamic acids, in particular octanohydroxamic acid, and one or more perfumes are considered.

Preferred for the purposes of the present invention are pigment mixtures of white pigments (for example kaolin, titanium dioxide or zinc oxide) and inorganic color pigments (for example iron oxide pigments, chromium oxides), the pigments being coated (coated) or uncoated can. Among the color pigments, iron oxides are particularly preferred. The pigments of the invention may be inorganic or organic.

White pigments are pigments whose optical effect is mainly based on non-selective light scattering (see also DIN 55944: 2003-11). Of the often chemically very similar fillers, inorganic white pigments differ in particular from their generally higher refractive index and, associated therewith, from their higher scattering power as well as from their application according to DIN 55943: 2001-10.

White pigments preferred according to the invention show no absorption in the visible light range, but a high scattering power which results in high hiding power. The scattering power is greater, the greater the difference between the refractive index of the white pigment and that of the surrounding medium. According to the invention advantageous white pigments are titanium dioxides (refractive indices: 2.55 for anatase and 2.75 for rutile) and zinc oxides (refractive index between 1.95 and 2.1). Particularly preferred is titanium dioxide.

Advantageous in the context of the present invention, the pigment or pigments can also be selected from the group of effect pigments, which of the cosmetic preparation in addition to the pure color an additional property - such. B. an angular dependence of the color (iridescent, flop), gloss (not surface gloss) or texture - confer. Such effect pigments are advantageously used according to the invention in addition to one or more white and / or color pigments.

The most important group of effect pigments are the luster pigments, which according to DIN 55944: 2003-11 include the metallic effect pigments and the pearlescent pigments. Some special effect pigments can not be assigned to these two groups, eg. As platelet-shaped graphite, platelet-shaped iron oxide and micronized titanium dioxide, wherein micronized titanium dioxide produces no gloss effect, but an angle-dependent light scattering effect. The luster pigments according to DIN 55943: 2001-10 are predominantly platelet-shaped effect pigments. Parallel oriented luster pigments show a characteristic shine. The optical effect of luster pigments is based on the directed reflection on metallic particles (metallic effect pigments), on transparent particles with high refractive index (pearlescent pigments) or on the phenomenon of interference (interference pigments) (DIN 55944: 2003-11).

Examples of commercially available effect pigments which are preferred according to the invention are: Timiron® from Merck, Iriodin® from Merck (pearl and color luster pigments for decorative technical applications), Xirallic® from Merck (color-intensive crystal effect pigments).

Furthermore, the preparations according to the invention may advantageously also contain organic color pigments, ie organic dyes which are practically insoluble in the preparation. According to DIN 55944: 1990-04, organic pigments can be classified according to chemical aspects into azo pigments and polycyclic pigments as well as according to color aspects into colored or black pigments. Organic white pigments are of no practical importance. Within the meaning of the present invention, the pigments can also be used advantageously in the form of commercially available oily or aqueous predispersions.

It is furthermore advantageous for the purposes of the present invention if the preparation according to the invention contains one or more dyes.

The dyes can be of both synthetic and natural origin.

Dyes which are suitable and approved for cosmetic purposes

Substances are used. Examples are Kochillerot A (C.I. 16255), Patent Blue V (C.1.42051), indigotine (C.1.73015), chlorophyllin (C.1.75810), quinoline yellow (C.I.47005).

Titanium dioxide (C.I.77891), Indanthrenblau RS (C.I. 69800) and Krapplack (C.I.58000).

These dyes are usually formulated in concentrations of 0.001 to 1% by weight, based on the total mixture.

The inventive preparations may also contain repellents.

 Most repellent agents belong to the classes of amides, alcohols, esters and

Ether on.

A modern repellent active ingredient is, for example, the 1-piperidinecarboxylic acid 2- (2-hydroxyethyl) -1-methylpropyl ester (INN: icaridin, CAS number: 1 19515-38-7, Elincs number: 423-210-8), the has the following structure:

Another frequently used repellent active ingredient is ethyl 3- (Nn-butyl-N-acetylamino) propionate (also referred to as ethylbutylacetylaminopropionate or Repellent 3535), which is characterized by the following structural formula:

Last but not least, the person skilled in the art knows the repellent active ingredient N, N-diethyl-3-methylbenzamide (meta-delphene, DEET), which has the following structure:

Active ingredients can also be added to the inventive formulations.

Examples of active substances are tocopherol, tocopherol acetate, tocopherol palmitate, ascorbic acid, (deoxy) ribonucleic acid and their fragmentation products, β-glucans, retinol, bisabolol, allantoin, phytantriol, panthenol, AHA acids, amino acids, ceramides, pseudoceramides, essential oils, plant extracts, such as B. Prunusextrakt, bamboo extract, linden blossom extract and vitamin complexes to understand.

In a preferred embodiment of the invention containing the preparations according to the invention at least one compound selected from vitamins, allantoin, bisabolol, glyceryl glucose and plant extracts.

In a preferred embodiment of the invention containing the preparations according to the invention at least one compound selected from tocopherol, tocopherol acetate, tocopherol palmitate, ascorbic acid, urea, ß-glucans, retinol, bisabolol, allantoin, phytantriol, panthenol, AHA acids, plant extracts and mixtures thereof.
