- Carbomers and ASE polymers belong to a class of materials known as hydrodynamic thickeners. These hydrodynamic thickeners include acid groups in their polymeric structure that, when deprotonated, form anionic charges that repel each other, causing the polymer chains to expand and entangle.
- Expansion and chain entanglement can give rise to thickening and suspending effects provided by the deprotonated polymers.
- the properties of these hydrodynamic thickeners are impacted by their molecular weight, acid group content, degree of cross-linking, and extent of swelling. These thickeners are also known as "space filling” or “volume excluding”, and tend to increase both viscosity and yield point as the concentration thereof is increased.
- hydrodynamic polymers commonly give rise to compositions that exhibit shear thinning or non-Newtonian behavior.
- Another class of (meth)acrylic acid based rheology modifiers are hydrophobically modified alkali swellable (HASE) polymers.
- the HASE polymers include acid groups, the deprotonation of which gives rise to polymer swelling. Additionally, the HASE polymers include hydrophobic side groups, chains or blocks that give rise to associative interactions with each other, as well as with other hydrophobic species present in the compositions in which they are employed, for example, hydrophobic groups of surfactants, fatty acids, other thickening agents, and the like. Association creates hydrophobic regions distributed throughout the polymer chain network. This can also help to enhance the properties of the materials as solubilizing agents. Aculyn® 22 and Aculyn® 28 copolymers from Dow and Aqua SF 1® copolymer from Lubrizol Corporation are among the commonly used HASE materials. U.S.

Description
Bio-based N-hydroxypyridone compounds The invention relates to bio-based N-hydroxypyridone compounds, a process for their preparation, cosmetic compositions comprising them, and the use of the bio- based N-hydroxypyridone compounds as anti-dandruff agents or preservatives. Preservation of cosmetic compositions extends their shelf life and therefore provides greater value for money for consumers. Furthermore, preservatives prevent consumers from distributing microbes around their home or on themselves and hence provide health benefits. Anti-microbial actives are well-described in the art and there are many available that provide excellent performance. Piroctone Olamine, also known as Octopirox® (Clariant) and as piroctone ethanolamine, is a compound used in the treatment of fungal infections. The chemical name for Piroctone Olamine is the monoethanolamine salt of 1 hydroxy- 4-methyl-6-(2,4,4-trimethylpentyl)-2(1H)-pyridone. Hence, Piroctone Olamine is the ethanolamine salt of piroctone. Piroctone Olamine is often used in anti- dandruff shampoos as an alternative to the commonly used compound zinc pyrithione. GB1440975, EP0158481, and WO2006/081969 describe the use of Piroctone Olamine as an anti-dandruff agent and/or as a preservative. Many ingredients for use in cosmetic compositions are traditionally derived from crude oil. Environmental, economic and sustainability questions are restricting the use of products derived from this limited resource. Therefore, there is a desire to identify more sustainable, yet gentle and effective materials. Indeed, consumers are very interested in “natural” products including products with a high percentage of “natural” compounds and/or compounds that are derived from renewable materials. Consumers perceive compounds derived from natural materials to be gentler and more environmentally friendly. Nevertheless, the availability of renewable ingredients for use in cosmetic compositions is still limited. There is a need for ingredients that are not only renewable, but also provide excellent performance. There is a need for cosmetic
ingredients that can provide the excellent performance of modern ingredients yet are from more renewable sources. The present invention relates to a compound of Formula (I) wherein Q+ is a cation; and
wherein the compound of Formula (I) has at least 10 wt-%, preferably at least 50 wt-%, more preferably at least 80 wt-%, particularly preferably 100 wt-%, bio- based carbon content, relative to the total mass of carbon in the compound of Formula (I). In preferred embodiments, the bio-based carbon content as used herein is measured according to standard ASTM D6866-12, Method B. In preferred embodiments, the bio-based carbon content of the compound of Formula (I) as used herein is measured according to standard ASTM D6866-12, Method B. In preferred embodiments, the bio-based carbon content of the compound of Formula (II) as used herein is measured according to standard ASTM D6866-12, Method B. In preferred embodiments, the bio-based carbon content of the compound of Formula (III) as used herein is measured according to standard ASTM D6866-12, Method B.

In preferred embodiments, the bio-based carbon content of isobutene as used herein is measured according to standard ASTM D6866-12, Method B.
The “bio-based content” is reported in ASTM D6866-12, Method B (see section 3.3.9 of ASTM D6866-12). “Bio-based carbon content”, “bio-based content”, “biogenic carbon content”, “bio-based content”, “biomass-derived carbon” herein refer to the same thing and are all measured in wt-%. Herein, the term “bio-based carbon content” is used. ASTM D6866-12, Method B lab results report the percentage of bio-based carbon content relative to total carbon, and not to total mass of the sample or molecular weight. A comment on bio-based carbon content calculation: ASTM D6866-12, Method B (see section 9 of ASTM D6866-12) requires the percent modern carbon value (pMC) reported to be multiplied by a correction factor of 0.95 to account for excess carbon-14 in the atmosphere due to nuclear weapons testing. Hence the term “bio-based carbon content” as used herein (if measured according to standard ASTM D6866-12, Method B) is defined by the equation: Bio-based carbon content = pMC * 0.95 (%) In preferred embodiments, the bio-based carbon content as used herein is measured according to standard ASTM D6866-21, Method B. In preferred embodiments, the bio-based carbon content of the compound of Formula (I) as used herein is measured according to standard ASTM D6866-21, Method B. In preferred embodiments, the bio-based carbon content of the compound of Formula (II) as used herein is measured according to standard ASTM D6866-21, Method B. In preferred embodiments, the bio-based carbon content of the compound of Formula (III) as used herein is measured according to standard ASTM D6866-21, Method B.

In preferred embodiments, the bio-based carbon content of the compound of Formula (V) as used herein is measured according to standard ASTM D6866-21, Method B. In preferred embodiments, the bio-based carbon content of isobutene as used herein is measured according to standard ASTM D6866-21, Method B. The “bio-based content” is reported in ASTM D6866-21, Method B. “Bio-based carbon content”, “bio-based content”, “biogenic carbon content”, “bio-based content”, “biomass-derived carbon” herein refer to the same thing and are all
measured in wt-%. Herein, the term “bio-based carbon content” is used. ASTM D6866-21, Method B lab results report the percentage of bio-based carbon content relative to total carbon, and not to total mass of the sample or molecular weight.

In at least one embodiment, the cosmetic composition is in liquid form. In an alternative embodiment, the cosmetic composition is in solid form. Optionally, the cosmetic composition is in powdered or granulated form. This is advantageous in that it is not needed to ship liquid, which is typically heavy, over long distances, which has economic and environmental benefits. A solid form can be achieved by spray drying the composition or by using a rotary evaporator. A solid form can also be achieved by extrusion or pressing. The composition can be converted into liquid form after it has been shipped, e.g. by adding water. The cosmetic composition of the invention preferably comprises one or more further components (F), which can be in an amount of at least 0.01% by weight, preferably at least 0.05% by weight, more preferably at least 0.1% by weight, even more preferably at least 0.5% by weight of the cosmetic composition. Preferably, the component (F) is selected from the group consisting of acidity regulators, colorants, conditioning agents, emulsifiers, film formers, fragrances, glossers, humectants, lubricants, moisturizers, pigments, preservatives, skin penetration enhancers, stabilizers, surfactants, thickeners, and viscosity modifiers. More preferably, the component (F) is selected from the group consisting of acidity regulators, glossers, lubricants, and surfactants. Suitable lubricants are, for example, fatty alcohol components having 6 to 18 carbon atoms. The surfactants may, for example, be selected from non-polymeric, cationic quaternary ammonium compounds, in particular cetrimonium chloride (CTAC). Suitable classical cationic conditioning agents include cationic quaternary ammonium salts. In at least one embodiment, the component (F) is a cationic quaternary ammonium salt. Examples of such quaternary ammonium salts include benzyl triethyl ammonium chloride, cetyl trimethylammonium chloride (cetrimonium chloride, CTAC), behentrimonium chloride (BTAC) or cetylpyridinium chloride.
As cationic components, a variety of cationic polymers are suitable, including quaternized cellulose ethers, copolymers of vinylpyrrolidone, acrylic polymers, including homopolymers or copolymers of dimethyldiallylammonium chloride or acrylamide. Also suitable are various types of homo- or copolymers derived from acrylic or methacrylic acid, acrylamide, methylacrylamide, diacetone-acrylamide. In at least one embodiment, the component (F) is a glosser. Typical glossers are silicones. Suitable as silicones are volatile or nonvolatile non-ionic silicone fluids, silicone resins, and silicone semisolids or solids. Volatile silicones are linear or cyclic silicones having a measureable vapor pressure, which is defined as a vapor pressure of at least 2 mm of mercury at 20°C. Also suitable are water insoluble nonvolatile silicone fluids including polyalkyl siloxanes, polyaryl siloxanes, polyalkylaryl siloxanes, polyether siloxane copolymers, amine-functional silicones, or mixtures thereof. The cosmetic composition of the invention may contain from 0.05 to 5%, preferably 0.5 to 5% by weight of at least one oil component. Typical oils are organic oils, which often are esters. The oil component may comprise glyceryl esters of fatty acids, or triglycerides, coconut oil, almond oil, apricot kernel oil, avocado oil, babassu oil, evening primrose oil, camelina sativa seed oil, grape seed oil, macadamia ternifolia seed oil, corn oil, meadowfoam seed oil, mink oil, olive oil, palm kernel oil, safflower oil, sesame oil, soybean oil, sunflower oil, wheat germ oil, and camellia reticulata seed oil. The cosmetic composition of the invention may contain from 0.05 to 5%, preferably 0.5 to 5% by weight of at least one emulsifier. Preferred emulsifiers are, for example, sorbitan esters. The cosmetic composition of the invention can contain from 0.1 to 10% by weight, preferably from 0.2 to 5% by weight, more preferably from 0.2 to 3% by weight, also more preferably from 0.5 to 5% by weight of at least one rheology modifying agent, in particular a gelling and thickening agent. Examples are cellulosic
thickeners, for example, hydroxyethylcellulose, hydroxypropylcellulose, and carboxymethylcellulose, guar gum, such as hydroxypropylguar, gums of microbial origin, such as xanthan gum and scleroglucan gum, and synthetic thickeners, such as crosslinked homo- or copolymers of acrylic acid and/or of acrylamidopropanesulphonic acid. Other rheology modifying agents include fatty acid amides such as coconut diethanolamide and monoethanolamide, and oxyethylenated monoethanolamide of carboxylic acid alkyl ether. Rheology modifying agents are also known as structuring materials. Common structuring materials include polymeric materials known as "carbomers", including, for example the cross-linked polyacrylic acid polymers available from Lubrizol Corporation under the trademark Carbopol®. Another class of (meth)acylic acid polymers are alkali-swellable emulsion (ASE) polymers. ASE polymers include, for example, Aculyn® 38 copolymer from Dow. Carbomers and ASE polymers belong to a class of materials known as hydrodynamic thickeners. These hydrodynamic thickeners include acid groups in their polymeric structure that, when deprotonated, form anionic charges that repel each other, causing the polymer chains to expand and entangle. Expansion and chain entanglement can give rise to thickening and suspending effects provided by the deprotonated polymers. The properties of these hydrodynamic thickeners are impacted by their molecular weight, acid group content, degree of cross-linking, and extent of swelling. These thickeners are also known as "space filling" or "volume excluding", and tend to increase both viscosity and yield point as the concentration thereof is increased. In use, hydrodynamic polymers commonly give rise to compositions that exhibit shear thinning or non-Newtonian behavior. Another class of (meth)acrylic acid based rheology modifiers are hydrophobically modified alkali swellable (HASE) polymers. Like ASE polymers, the HASE polymers include acid groups, the deprotonation of which gives rise to polymer swelling. Additionally, the HASE polymers include hydrophobic side groups, chains or blocks that give rise to associative interactions with each other, as well as with other hydrophobic species present in the compositions in which they are employed, for example, hydrophobic groups of surfactants, fatty acids, other thickening agents, and the like. Association creates hydrophobic regions distributed throughout the polymer chain
network. This can also help to enhance the properties of the materials as solubilizing agents. Aculyn® 22 and Aculyn® 28 copolymers from Dow and Aqua SF 1® copolymer from Lubrizol Corporation are among the commonly used HASE materials. U.S. Patent 4,529,773 (Witiak et al.) reports alkali-soluble emulsion polymers activated by neutralization to a pH above 6.5, and subsequently acidified in the presence of a surfactant. These are described as useful thickeners in acidic compositions. The polymers are formed from the copolymerization of a monomer system that includes: (1) methacrylic or acrylic acid, (2) methacrylic or acrylic acid ester of a C8-C30 alkyl or, as therein more particularly described, a hydrocarbyl monoether of polyethylene glycol, (3) a C1-C4 alkyl acrylate or methacrylate, and, optionally, (4) a small amount of a polyethylenically unsaturated monomer. The cosmetic composition of the invention can also comprise as component (F) a fatty compound. The fatty compound may be included in the cosmetic composition at a level of from 0.1 to 20 % by weight, preferably from 1.0 to 10 % by weight. The fatty compound is selected from the group consisting of fatty alcohols (e.g. cetyl alcohol, stearyl alcohol or cetearyl alcohol), fatty acids, fatty alcohol derivatives, fatty acid derivatives, or mixtures thereof. It is understood that the components disclosed can in some instances fall into more than one classification, e.g., some fatty alcohol derivatives can also be classified as fatty acid derivatives. However, a given classification, is not intended to be a limitation on that particular compound but is done so for convenience of classification and nomenclature. Non-limiting examples are found in International Cosmetic Ingredient Dictionary and Handbook, Fourteenth Edition (2014), and CTFA Cosmetic Ingredient Handbook, Second Edition, 1992. Preferably, fatty alcohols have 14 to 30 or 16 to 22 carbon atoms. These fatty alcohols are saturated and can be linear or branched. Examples of fatty alcohols are cetyl alcohol, stearyl alcohol, behenyl alcohol, and mixtures thereof. Preferred fatty acids have from 10 to 30 or from 12 to 22 carbon atoms. These fatty acids can be saturated and can be linear or branched. Also included herein are salts of these fatty acids.

The fatty alcohol derivatives and fatty acid derivatives useful herein include alkyl ethers of fatty alcohols, alkoxylated fatty alcohols, alkyl ethers of alkoxylated fatty alcohols, esters of fatty alcohols, fatty acid esters of compounds having esterifiable hydroxy groups, hydroxy-substituted fatty acids, or mixtures thereof.

The cosmetic composition of the invention may comprise an aqueous carrier. The level and species of the aqueous carrier are selected according to the compatibility with other components and other desired characteristic of the cosmetic composition. The aqueous carrier may, for example, be water or water solutions of lower alkyl alcohols or polyhydric alcohols. The lower alkyl alcohols may, for example, be monohydric alcohols having 1 to 6 carbons, often ethanol and/or isopropanol. The polyhydric alcohols may, for example, be propylene glycol, hexylene glycol, glycerin, and/or propane diol. Preferably, the aqueous carrier is substantially water. Deionized water is preferably used. Water from natural sources, including minerals can also be used, depending on the desired characteristic of the composition. Generally, the cosmetic composition of the invention can comprise up to 80 %, often even up to 95 % by weight of water. The cosmetic composition of the invention may also include as a further component (F) other components being suitable for rendering the compositions more cosmetically or aesthetically acceptable or to provide them with additional usage benefits.

Preferably, salt is present at levels from 0.1 to 1 wt.-% of the total cosmetic composition to adjust the product viscosity. Preferably, NaOH is present at levels from 0.1 to 1 wt.-% of the total cosmetic composition to adjust the pH of the composition. The cosmetic composition of the invention may contain as a further component (F) a polysorbate for adjusting rheology, for example, polysorbate-20, polysorbate-21, polysorbate-40, polysorbate-60, or mixtures thereof. The polysorbate can be contained in the cosmetic composition in amounts up to 5% (e.g.0.1 to 5%) by weight. The cosmetic composition of the invention can also contain as a further component (F) a polypropylene glycol. Preferred polypropylene glycols are those having a weight average molecular weight of from 200 to 100000 g/mol. The polypropylene glycol may be either water-soluble, water-insoluble, or may have a limited solubility in water, depending upon the degree of polymerization and whether other moieties are attached thereto. The desired solubility of the polypropylene glycol in water will depend in large part upon the form of the composition (e.g., leave-on composition, rinse-off composition). The polypropylene
glycol can be included in the cosmetic composition of the invention at a level of up to 10% by weight. For example, in a rinse-off composition, it is preferred that the polypropylene glycol has a solubility in water at 25°C of less than about 1 g/100 g water, more preferably a solubility in water of less than about 0.5 g/100 g water, and even more preferably a solubility in water of less than about 0.1 g/100 g water. The polypropylene glycol can be included in the cosmetic composition of the invention at a level of up to 10% by weight. The cosmetic composition of the invention can also contain, as a further component (F), low melting point oil selected from the group consisting of hydrocarbons having from 10 to 40 carbon atoms; unsaturated fatty alcohols having from 10 to 30 carbon atoms such as oleyl alcohol; unsaturated fatty acids having from about 10 to about 30 carbon atoms; fatty acid derivatives; fatty alcohol derivatives; ester oils such as pentaerythritol ester oils, trimethylol ester oils, citrate ester oils, or glyceryl ester oils; poly [alpha]-olefin oils; and mixtures thereof. Preferred low melting point oils are selected from the group consisting of ester oils such as pentaerythritol ester oils, trimethylol ester oils, citrate ester oils, or glyceryl ester oils; poly [alpha]-olefin oils; and mixtures thereof. Particularly useful pentaerythritol ester oils and trimethylol ester oils are pentaerythritol tetraisostearate, pentaerythritol tetraoleate, trimethylolpropane triisostearate, trimethylolpropane trioleate, or mixtures thereof. Particularly useful glyceryl esters are triisostearin, triolein or trilinolein. The cosmetic composition of the invention can also contain, as a further component (F), a cationic polymer. Cationic polymers may be present in the cosmetic composition of the invention for further enhancing deposition performance. Suitable cationic polymers may be homopolymers which are cationically substituted or may be formed from two or more types of monomers. The weight average (Mw) molecular weight of the polymers will generally be between 100000
and 2 million g/mol. The polymers will have cationic nitrogen containing groups such as quaternary ammonium or protonated amino groups, or a mixture thereof. If the molecular weight of the polymer is too low, then the conditioning effect is poor. If too high, then there may be problems of high extensional viscosity leading to stringiness of the composition when it is poured. The cationic nitrogen-containing group will generally be present as a substituent on a fraction of the total monomer units of the cationic polymer. Thus, when the polymer is not a homopolymer it can contain non-cationic spacer monomer units. Such polymers are described in the CTFA Cosmetic Ingredient Directory, 3rd edition. The ratio of the cationic to non-cationic monomer units is selected to give polymers having a cationic charge density in the required range, which is generally from 0.2 to 3.0 meq/gm. The cationic charge density of the polymer is suitably determined via the Kjeldahl method as described in the US Pharmacopoeia under chemical tests for nitrogen determination. Suitable cationic polymers include, for example, copolymers of vinyl monomers having cationic amine or quaternary ammonium functionalities with water soluble spacer monomers such as (meth)acrylamide, alkyl and dialkyl (meth)acrylamides, alkyl (meth)acrylate, vinyl caprolactone and vinyl pyrrolidine. The alkyl and dialkyl substituted monomers preferably have C1-C7 alkyl groups, more preferably C1-3 alkyl groups. Other suitable spacers include vinyl esters, vinyl alcohol, maleic anhydride, propylene glycol and ethylene glycol. The cationic amines can be primary, secondary or tertiary amines, depending upon the particular species and the pH of the composition. In general, secondary and tertiary amines, especially tertiary, are preferred. Amine substituted vinyl monomers and amines can be polymerized in the amine form and then converted to ammonium by quaternization. The cationic polymers can comprise mixtures of monomer units derived from amine- and/or quaternary ammonium-substituted monomer and/or compatible spacer monomers. Suitable cationic polymers include, for example cationic diallyl quaternary ammonium-containing polymers including, for example, dimethyldiallylammonium
chloride homopolymer and copolymers of acrylamide and dimethyldiallylammonium chloride, referred to in the industry (CTFA) as Polyquaternium 6 and Polyquaternium 7, respectively; mineral acid salts of amino- alkyl esters of homo- and co-polymers of unsaturated carboxylic acids having from 3 to 5 carbon atoms, (as described in US4009256A1 from NAT STARCH CHEM CORP); cationic polyacrylamides (as described in WO95/22311A1 Unilever PLC). Other cationic polymers that can be used include cationic polysaccharide polymers, such as cationic cellulose derivatives, cationic starch derivatives, and cationic guar gum derivatives. Cationic polysaccharide polymers suitable for use in the cosmetic composition of the invention include monomers of the formula: A-O-[R-N+(R1)(R2)(R3)X-], wherein: A is an anhydroglucose residual group, such as a starch or cellulose anhydroglucose residual. R is an alkylene, oxyalkylene, polyoxyalkylene, or hydroxyalkylene group, or combination thereof. R1, R2 and R3 independently represent alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, or alkoxyaryl groups, each group containing up to about 18 carbon atoms. The total number of carbon atoms for each cationic moiety (i.e., the sum of carbon atoms in R1, R2 and R3) is preferably about 20 or less, and X- is an anionic counterion. Another type of cationic cellulose includes the polymeric quaternary ammonium salts of hydroxyethyl cellulose reacted with lauryl dimethyl ammonium-substituted epoxide, referred to in the industry (CTFA) as Polyquaternium 24. These materials are available from the Amerchol Corporation, for instance under the trade name Polymer LM-200. Other suitable cationic polysaccharide polymers include quaternary nitrogen-containing cellulose ethers (e.g. as described in US3962418 from L’Oréal), and copolymers of etherified cellulose and starch (e.g. as described in US3958581 from L’Oréal). A particularly suitable type of cationic polysaccharide polymer that can be used is a cationic guar gum derivative, such as guar hydroxypropyltrimethylammonium chloride (commercially available from Solvay in their JAGUAR trade named
series). Examples of such materials are JAGUAR C13S, JAGUAR C14, JAGUAR C15, JAGUAR C17, JAGUAR C16, JAGUAR CHT and JAGUAR C162. Mixtures of any of the above cationic polymers may be used.
