Abstract

The present application relates to cosmetic deodorants and antiperspirants containing as stabilized antioxidant at least one ascorbic acid derivative selected from certain alkylascorbyl ethers.

Description

The present application relates to cosmetic deodorants and antiperspirants containing as stabilized antioxidant at least one ascorbic acid derivative selected from certain alkylascorbyl ethers.

Washing, cleansing and caring for one's own body is a fundamental human need, and modern industry is constantly trying to meet these needs of man in a variety of ways. Especially important for daily hygiene is the permanent elimination or at least reduction of body odor. Numerous specific deodorant or antiperspirant personal care products are known in the art which have been developed for use in body regions having a high density of sweat glands, especially in the underarm area. These are packaged in a wide variety of dosage forms, for example as powder, in stick form, as aerosol spray, pump spray, liquid and gel roll on application, cream, gel and as a soaked flexible substrate (towels).

Cosmetic compositions, in particular deodorants and antiperspirants, usually contain at least one oil or one fatty substance and in any case always a fragrance component or a perfume.

These ingredients are highly susceptible to chemical reactions with oxygen or other oxidative processes that alter or even destroy the molecular structure. On the one hand, this means that the degraded ingredient can no longer fulfill its actual function in the cosmetic. In the worst case, the reaction products lead to discoloration and / or aroma defects or to a bad odor of the cosmetic composition. This makes the cosmetic unacceptable to the consumer.

In order to protect the ingredients of a cosmetic against such oxidative reactions, one or more antioxidants are added. An antioxidant generally serves to inhibit or prevent the oxidative reactions described above, and to protect fats and oils from rancidity and gumming, and fragrances from their degradation and the formation of undesirable perfume components (flavor defects). Furthermore, an antioxidant is used to prevent discoloration of the cosmetic by the formation of undesirable components.

The stabilization of cosmetics by antioxidants is of course well known in the art. Antioxidants used by default include tocopherols (vitamin E), tocotrienols, flavonoids, butylhydroxyanisole (BHA), butylhydroxytoluene (BHT), ascorbyl palmitate (= 6-palmitoyl-L-ascorbic acid) and gallic acid esters, especially propyl gallate. Butylated hydroxyanisole and butylated hydroxytoluene are being rejected by some consumers for toxicological reasons. In addition, butylhydroxyanisole has no heat stability, so it is not suitable for compositions whose preparation requires the supply of heat. For gallic acid esters, in particular propyl gallate, a skin-sensitizing potential is discussed. Since all of the aforementioned antioxidants are fat-soluble, but not water-soluble, there is the potential that they may accumulate in the organism, which may be undesirable from a toxicological point of view or which limits the use levels of these substances from the outset strongly.

A known water-soluble antioxidant is ascorbic acid, especially L-ascorbic acid. In addition to their antioxidant activity, ascorbic acid, its esters and its glucose ethers are made WO2001 / 099376 A2 and WO2003 / 039505 A2 known as inhibitors of the enzymes arylsulfatase and beta-glucuronidase, which qualifies them as deodorant agents. The problem with using ascorbic acid, its esters and its glucose ethers in aluminum salt-containing antiperspirants is that traces of iron (III) unavoidably released from the antiperspirant aluminum salts initiate radical reactions, causing ascorbic acid, its esters and their derivatives Glucose ethers, but also substances such as perfume oils are destroyed. In addition, dehydroascorbic acid forms as a reaction product, resulting in discoloration of the agent.

State of the art

DE 10 2007 028 506 A1 discloses cosmetic deodorants and antiperspirants containing the flavonoid dihydroquercetin (taxifolin, 3,3 ', 4', 5,7-pentahydroxyflavanone) as an antioxidant.

task

The object of the present invention was to provide cosmetic deodorants and antiperspirants which are hydrophilic or water-soluble. This is particularly important for deodorants whose carrier consists essentially of the hydrophilic solvent ethanol. A further object of the present invention was to enrich the state of the art with effective alternative deodorants and antiperspirants, which are stable to oxidative reactions, in particular to oxygen, and at the same time very well tolerated by the skin, especially for the sensitive skin in the underarm area.

A further object of the present invention was to provide an ascorbic acid-based antioxidant for cosmetic deodorants and antiperspirants, which does not lead to degradation and discoloration of the agent even in the presence of antiperspirant aluminum salts.

Apocrine sweat is a complex mixture that includes sebum and other fats as well as steroids. Steroids themselves are not water soluble. In order to be carried away with the body fluids, they are usually present as sulfate or as glucuronide. On the skin, the cleavage of these steroid esters in the volatile free steroids by hydrolytic enzymes of the skin bacteria, especially the coryneform bacteria. In principle all bacterial exoesterases are capable of this, but especially the enzymes arylsulfatase and beta-glucuronidase. Compounds which inhibit arylsulfatase or beta-glucuronidase therefore represent preferred deodorant active ingredients according to the invention.

The development of short- and medium-chain fatty acids, which contribute significantly to body odor, begins with the cleavage of skin lipids to branched long-chain fatty acids. The cleavage of the skin lipids, which are present predominantly as glycerol esters, takes place essentially by Propionibacterium, Corynebacterium A and Staphylococcus species ( AG James et al., Generation and Turnover of Volatile Fatty Acids by Axillary Bacteria, 22nd IFSCC Congress, Edinburgh, 2002, Poster 108 ). AG James et al. further disclose that from the long-chain branched fatty acids by the hydrolytic enzymes of a particular Corynebacterium, the AG James et al. Corynebacterium A, both short-chain C ₂ -C ₅ fatty acids and medium-chain C ₆ -C ₁₂ fatty acids are formed, which are mainly responsible for the axillary body odor. In principle, all bacterial exoesterases are capable of this lipid cleavage, but especially the enzyme lipase. Compounds which inhibit lipase are therefore also preferred deodorant agents according to the invention.

Another class of compounds which also results from the bacterial decomposition of the sweat constituents and which contributes to body odor are saturated and unsaturated aldehydes, especially those having a chain length of C ₆ -C ₁₂ , in particular hexanal, heptanal, octenal and nonenal. These are formed by beta-cleavage from the hydroperoxides, which are formed under the action of 5-lipoxygenase on unsaturated fatty acids. Compounds which inhibit the enzyme 5-lipoxygenase are therefore also preferred deodorant agents according to the invention.

Furthermore, it is known that strongly malodorous components of human body odor and bad breath, in particular by enzymatic reaction released volatile sulfur compounds, so-called "volatile sulfur compounds" (VSC) represent. Sulfur-containing compounds come as water-soluble amino acid conjugates with the sweat on the human skin. There they are released by skin bacteria (especially staphylococci and corynebacteria) by enzymatic reaction. An enzyme that plays a special role in the release of VSCs is cystathionine beta-lyase. This enzyme breaks down VSCs from the amino acids and is therefore an important cause in the development of Body odor. Compounds that inhibit the enzyme cystathionine beta-lyase, therefore, also according to the invention are preferred deodorant agents.

The necessary physical and chemical properties are a low molecular weight of at most 300 g / mol, a high vapor pressure, minimal water and high lipid solubility and weak polarity and the presence of at least one osmophoric group in the molecule. In order to delineate volatile, low molecular weight substances which are usually and also not regarded as perfuming agents, but primarily as solvents, for example ethanol, propanol, isopropanol and acetone, according to the invention fragrances have a molecular weight of 74 to 300 g / mol, contain at least one osmophoric group in the molecule and have a smell and / or taste, that is, they excite the receptors of the hair cells of the olfactory system.

As perfumes, perfumes, perfume oils or perfume oil ingredients can be used. Perfume oils or fragrances can according to the invention individual fragrance compounds, eg. As the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate (DMBCA), phenylethylacetate, benzylacetate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate, benzylsalicylate, cyclohexylsalicylate, floramate, melusate and jasmecyclate. The ethers include, for example, benzyl ethyl ether and ambroxane, to the aldehydes, for example, the linear alkanals with 8-18 carbon atoms, citral, citronellal, citronellyloxy-acetaldehyde, cyclamen aldehyde, lilial and bourgeonal, to the ketones such as the ionone, alpha-isomethylionone and Methylcedrylketon , to the alcohols anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, to the hydrocarbons mainly include the terpenes such as limes and pinene. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance.

Particularly preferred deodorant or antiperspirant compositions according to the invention contain at least one perfume in a total amount of 0.00001 to 10 wt .-%, preferably 0.5-7 wt .-%, most preferably 1-6 wt .-%, each based on the total weight of the agent, without taking into account any existing propellant.
