Definitions

  • the present invention relates to cosmetic cleaning agents. Such means are known per se. These are essentially surface-active substances or mixtures of substances that are offered to the consumer in various preparations.
  • Cleaning means the removal of (environmental) dirt and thus increases the psychological and physical well-being.
  • Cleaning the surface of skin and hair is a very complex process that depends on many parameters.
  • substances coming from outside such as hydrocarbons or inorganic pigments from a wide variety of environments, as well as residues from cosmetics or undesired microorganisms, should be removed as completely as possible.
  • the body's excretions such as sweat, sebum, skin and hair flakes can be washed off without deep intervention in the physiological balance.
  • Cosmetic or dermatological cleansing preparations are so-called “rinse off” preparations, which are rinsed off the skin after use. They are generally applied in the form of a foam with water to the parts of the body to be cleaned. All cosmetic or dermatological cleansing preparations are based on detergent surfactants.
  • Surfactants are amphiphilic substances that can dissolve organic, non-polar substances in water and are characterized by an ambivalent behavior towards water and lipids: the surfactant molecule contains at least one hydrophilic and one lipophilic group, which bind to the interface between these two classes of substances In this way, surfactants ensure a reduction in the surface tension of the water, wetting of the skin, facilitating the removal and removal of dirt, easy rinsing and - if desired - also for foam regulation. This is the basis for the dirt Removal of lipid-containing contaminants.
  • hydrophilic parts of a surfactant molecule are mostly polar functional groups, for example -COO " , -OSO 3 2" , -SO 3 " , while the hydrophobic parts generally represent non-polar hydrocarbon residues.
  • Surfactants are generally classified according to Art and charge of the hydrophilic part of the molecule. There are four groups:
  • 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 environment. Cationic surfactants are characterized almost exclusively by the presence of a quaternary ammonium group. In aqueous solutions they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and accordingly behave like anionic or cationic surfactants in aqueous solution depending on the pH. 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 should illustrate:
  • B + any cation, eg Na +
  • Non-ionic surfactants do not form ions in an aqueous medium.
  • the detergent surfactants in cosmetic and dermatological cleaning agents are subject to a very critical assessment with regard to their dermatological and ecological behavior. The latter is particularly important because they are used in considerable quantities and are discharged as intended after use.
  • the horny layer of the skin swells.
  • the degree of this swelling depends, among other things, on the duration of the bath and its temperature.
  • water-soluble substances are washed off or washed out, e.g. B. water-soluble dirt components, but also the skin's own substances, which are responsible for the water retention capacity of the horny layer.
  • Skin oils are also dissolved and washed out to a certain extent by the skin's own surface-active substances. After initial swelling, this causes the skin to dry out subsequently.
  • detersive surfactants which are intended to clean the skin and hair of greasy and water-soluble dirt components, also have a degreasing effect on normal skin lipids. Every time the skin is cleaned, intercomomeocytic lipids and sebum components are also removed to different degrees. This means that the natural water-lipid coat of the skin is more or less disturbed with every wash. This can lead to a short-term change in the barrier function of the skin, particularly in the case of extreme degreasing, the course of which the condition of the treated skin region also has a considerable influence on the changes shown. For example, the thickness of the skin, the number of sebum and sweat glands and the sensitivity associated with it can vary considerably.
  • wash-active surfactants are as inactive as possible in order to avoid undesirable side effects. They should develop their cleaning effect with optimal mildness, best skin compatibility and low degreasing.
  • cosmetic or dermatological cleaning preparations are very well tailored to an assumed range of applications, since the mechanical parameters, such as the time factor, which vary depending on the application, are of particular importance for a defined, mild cleaning effect.
  • Cosmetic cleaning agents usually contain mixtures of different types of surfactants. The selection is primarily based on skin tolerance and the desired cosmetic performance of the surfactants. In addition, foaming power, formulability and a favorable performance / cost ratio play an important role.
  • the present invention relates to cosmetic cleaning agents in the form of shaped soap products.
  • Such means are known per se. These are essentially surface-active substances or mixtures of substances that are offered to the consumer in various preparations.
  • the invention relates in particular to bar soaps with improved smoothness and increased lime soap dispersing capacity due to a content of talc and one or more amphoteric surfactants with a simultaneous absence of alkyl (oligo) glycosides.
  • syndet bars so-called “syndet bars” occupy a special position. Apart from impurities, they are free of fatty acid salts and contain only synthetic surfactants. In Germany alone, several million soap bars are sold every year for personal hygiene.
  • bar soaps not only have to clean the skin, they also have to take care of it, ie prevent it from drying out, relubricate it and offer protection against external influences.
  • the soap is particularly skin-friendly, but in use it should nevertheless produce as much and creamy foam as possible and cause a pleasant feeling on the skin.
  • bar soap manufacturers are constantly looking for new ingredients that meet this increased requirement profile.
  • the main components are the alkali salts of the fatty acids of natural oils and. Fats, preferably the chain lengths C ⁇ 2 -Ci8. Since lauric acid soaps foam particularly well, the lauric acid-rich coconut and palm kernel oils are preferred raw materials for fine soap manufacture.
  • the sodium salts of the fatty acid mixtures are solid, the potassium salts are soft-pasty. For saponification, the dilute sodium or potassium hydroxide solution is added to the fat raw materials in a stoichiometric ratio in such a way that an excess of lye of at most 0.05% is present in the finished soap. In many cases, soaps are no longer made directly from fats, but from the fatty acids obtained through fat splitting.
  • Usual soap additives are fatty acids, fatty alcohols, lanolin, lecithin, vegetable oils, partial glycerides and other fat-like substances for regreasing the cleansed skin, antioxidants such as ascorbyl palmitate or tocopherol to prevent the autoxidation of soap (rancidity), complexing agents such as nitrilotriacetate Heavy metal traces that could catalyze autoxidative spoilage, perfume oils to achieve the desired fragrance notes, dyes to color the soap bars and, if required, special additives.
  • Deodorant soaps with additives of deodorising agents such as. B. 3,4,4'-
  • Trichlorocarbanilide (triclocarban); Cream soaps with particularly high proportions of lipid-replenishing and skin-creaming substances;
  • Baby soaps with good regreasing and additional nourishing components such as B. chamomile extracts, at most very slightly perfumed;
  • the present invention relates to liquid soaps or washing lotions.
  • Such products are not only used to clean the hands, but usually also for the whole body, including the face. Accordingly, they are also suitable for use as a shower preparation.
  • the development of these products focuses on the dermatological requirements, since the skin comes into intensive contact with the concentrated surfactant solution. Special emphasis is therefore placed on the selection of mild surfactants in low concentrations. Further criteria are good foaming power as well as a pleasant, refreshing fragrance and the simultaneous care of the skin.
  • Washing lotions and shower baths in particular generally have viscosities of around 3,000 to 10,000 mPa-s, which on the one hand allow the product to be spread easily with quick foaming, but on the other hand should be high enough to enable perfect use by hand or washcloth.
  • Liquid soaps or washing lotions are generally characterized by a more or less high water content, but usually do not have a noticeable care effect, since they have only a low oil content.
  • the present invention relates to a relatively new technical development, namely shower preparations containing surfactants with a high oil content.
  • German Offenlegungsschrift 44 24 210 describes metallic or dermatological shower preparations with a surfactant content of at most 55% by weight and an oil content of more than 45% by weight, the preparations being essentially water-free. Due to the high oil content, these preparations have a regenerating effect on the general skin condition. At the same time, they have good foam development and high cleaning power.
  • WO 96/17591 describes foaming liquid skin cleaning compositions which contain the following substances: 5 to 30% by weight of a moisturizing active ingredient which has a Vaughan Solubility Parameter (VSP) of 5 to 10, 0.3 to 5% by weight. % of a water-dispersible gel-forming polymer, 5 to 30% by weight of a synthetic surface-active substance, 0 to 15% by weight of a C 8 to C- 4 fatty acid soap and water, the preparations having a lipid deposition value (LDV) from at least 5 to 1000 and wherein the synthetic surfactant and the soap have a common CMC equilibrium surface tension value of from 15 to 50.
  • VSP Vaughan Solubility Parameter
  • the present invention also relates to cleaning products based on emulsions. These are formulated in such a way that the emulsion is stabilized with emulsifiers and then a surfactant system is adapted.
  • Emulsifiers also have an amphiphilic structure, so their structure is comparable to that of surfactants. Emulsifiers enable or facilitate the uniform distribution of two or more immiscible phases and at the same time prevent their separation. Since emulsions are generally destroyed by the addition of surfactants, the choice of surfactant system is severely restricted and the cleaning preparations obtained are based on expensive and complicated formulations.
  • HLB value a dimensionless number between 0 and 20
  • HLB value a dimensionless number between 0 and 20
  • Numbers below 9 indicate oil-soluble, hydrophobic emulsifiers, numbers above 11 water-soluble, hydrophilic.
  • the HLB value says something about the balance between the size and strength of the hydrophilic and lipophilic groups of an emul gators out. From these considerations it can be deduced that the effectiveness of an emulsifier can also be characterized by its HLB value.
  • the following table shows the relationship between the HLB value and the possible area of application:
  • the HLB value of an emulsifier can also be composed of increments, the HLB increments for the various hydrophilic and hydrophobic groups from which a molecule is composed can be found in tables.
  • HLB values can also be determined for detergent surfactants in this way, although the HLB system was originally designed only for emulsifiers. It can be seen that wash-active substances generally have HLB values that are significantly greater than 20.
  • the object of the present invention was to provide cleaning preparations based on emulsions which remedy the disadvantages of the prior art and which are accordingly based on simple and inexpensive formulations.
  • the preparations should also have a high care effect without detracting from the cleaning effect.
  • the present invention relates to cosmetic and dermatological cleaning preparations in the form of gels
  • Cosmetic gels are extremely popular with consumers. Since they are mostly transparent, often colored but just as often should be colorless, they offer the cosmetic developer additional design options, some of which have a functional character, but some of which only serve to improve the external appearance. For example, the product, which is then usually presented to the viewer in transparent packaging, can be worked color pigments, gas bubbles and the like, or even larger objects, interesting optical effects are given.
  • Another object was to provide cleaning preparations which, if desired, can be designed as visually appealing, stable gels.
  • the present invention further relates to wash-active hair cosmetic preparations, generally referred to as shampoos.
  • the present invention relates to hair cosmetic active ingredient combinations and preparations for the care of the hair and scalp.
  • the prior art lacks shampoo formulations which provide damaged hair with satisfactory care. The task was therefore to remedy these disadvantages of the prior art.
  • Iminodisuccinic acid has the following structure, although there is probably a balance of tautomeric forms:
  • cosmetic or dermatological preparations contain 0.1 to 20% by weight, advantageously 0.5 to 10% by weight, very particularly preferably 1 to 5% by weight of iminodisuccinic acid and / or its salts.
  • the cosmetic and / or dermatological cleaning preparations in the sense of the present invention are based on simple and inexpensive formulations. They have good foam development and high cleaning power at the same time.
  • the preparations have a regenerating effect on the general skin condition, reduce the feeling of dryness of the skin and make the skin supple.
  • the cleaning preparations advantageously contain one or more wash-active anionic, cationic, amphoteric and / or non-ionic surfactants according to the invention.

Hydrocolloids are macromolecules that are largely linear in shape and have intermolecular interaction forces that enable secondary and main valence bonds between the individual molecules and thus the formation of a network-like structure. They are partially water-soluble natural or synthetic polymers that form gels or viscous solutions in aqueous systems. They increase the viscosity of the water by either binding water molecules (hydration) or by absorbing and enveloping the water in their intertwined macromolecules, while at the same time restricting the mobility of the water.
  • Such water-soluble polymers represent a large group of chemically very different natural and synthetic polymers, the common feature of which is their solubility in water or aqueous media. The prerequisite for this is that these polymers have a sufficient number of hydrophilic groups for water solubility and are not too strongly crosslinked.
