| PATENT DESCRIPTION |
The present invention relates to deodorant and/or antiperspirant cosmetic compositions comprising an alkyl ester or a mixture of alkyl esters. More specifically, the present invention relates to deodorant and/or antiperspirant cosmetic compositions comprising an alkyl ester or a mixture of alkyl esters and one or more carrying agents, having a very high skin compatibility and respect for resident bacterial flora. The above compositions can be in various physical forms such as, for example, aerosols, foams, lotions, gels, emulsions, dusting powders, suspensions, multiple phase systems, sticks, which can be packaged in various types of cosmetic containers to facilitate skin application such as, for example, aerosol or self-foaming bombs pressurized with propellants or with mechanical systems, sprays, pumps, dispensers, tubes, flasks, roll-on containers, stick containers or jars. These compositions are particularly suitable in all cases of excessive perspiration or for moderating normal perspiration, in cases of the necessity for deodoration in individuals with a sensitive skin and, in particular, in the case of individuals with skin sensitive to the traditional deodorants based on bacterial substances. Alkyl esters such as, for example, alkyl esters of lactic, malic and tartaric acid, are lipids with a good solubility in various systems and in various cosmetic carrying agents such as, for example, hydrocarbons, triglycerides, esters, lower and higher alcohols, glycols, silicons, and have various polarities, thanks to their particular chemical structure. In fact, alkyl esters have, in their molecular structure, a paraffinic part (the alkyl chain) and an extremely polar part represented by the ester group associated with a hydroxyl group in position .alpha.; this chemical structure guarantees the homogeneous distribution in the hydro-lipidic film of the stratum corneum and adhesion to the surface keratin structures of the skin. In addition, their relatively easy hydrolysis produces fatty alcohols and lactic acid, the latter capable of inihibiting bacterial proliferation and the action of lipases which decompose the surface sebum forming volatile, badly-smelling, short-chain compounds. As already mentioned above, thanks to their easy solubility in various systems and in various cosmetic carrying agents, they can be easily distributed homogeneously on the skin by means of numerous carriers, without creating insolubilization phenomena after their progressive disappearance by skin absorption or volatilization of the components of the cosmetic carrier used. Body odour is an intrinsic characteristic of human beings, due to their kind, race, family of origin, linked to behavioural habits such as food, smoking, lifestyle, work and pleasure environments, personal hygiene. Body odour is mostly due to a combination of secretions of various glands of the skin surface, apocrines and ecrines, which secrete aqueous liquids and fatty fluids. These secretions are practically odourless when they reach the surface of the skin but, in a short time, they are decomposed by bacterial flora, creating short chain, volatile compounds, fatty acids and aldehydes having an unpleasant odour. In modern society, body odour must be disguised as it causes an unpleasant impact on others and is considered as a sign of poor hygiene. In addition, it is made worse by clothes which often prevent the normal evaporation of the volatile compounds in an imperceptible way to smell. Cosmetic technology is trying to combat this odour in the following ways: with bactericidal substances: the resident bacterial flora is killed thus preventing the decomposition of sweat and the formation of odour; the disadvantages of their action are the elimination of the protective effect of the resident bacterial flora and the consequent possibility of the proliferation of exogenous species, the formation of resistant stocks and the possibility of irritation and allergies as a result of the constant contact with the skin, under occluding conditions, of bactericides which are among the most frequent allergy-causing substances in cosmetics; the above phenomena are due to the facility of trans-skin absorption under the conditions of use and reactivity of the bactericidal molecules with the cellular membranes of the skin cells; with perfumes: in this case there is a coverage action of the body odour; the disadvantages of this action are linked to the possible allergy-causing effect of the perfumes again enhanced by the occluding and extremely hydrated conditions of the armpits; with odour-absorbing substances: these substances are capable of stably coordinating various odorous molecules around organic zinc compounds; their action, however, is incomplete and there can also be occlusions; with enzymatic deviators: these substances are capable of inhibiting the action of lipasic enzymes on the lipids secreted from the sebaceous glands; their action, however, is temporary and strictly linked to the quantity of inhibitor present and the skin pH; with volatile alcohols: for example, ethyl alcohol; their action, however, is temporary and can facilitate irritation on sensitive skins and also allergies due to the carrying action of the alcohols; with astringent substances: for example, aluminium salts with strong acid anions; these substances cause reduced perspiration but are not without dermatological risks and their astringent action prevents natural perspiration of the skin, they are also not recommended on damaged skin. The above effects are widely described in literature such as, for example, by: Pelfini O. in "cosmetics in dermatology practice: An inquiry on the use and induced side-effects", in "Journal Applied Cosmetology" (1987), Vol. 5, pages 1-36; by Melis S. and Mignini E. in "Cosmesi Dermatologica" (1987), Year 3, N.degree. 12, pages 13-26; by Wishart J. M.: "Generalized exfoliative dermatitis due to contact with antiperspirant", in "British Journal of Clinical Practice" (1974), Vol. 28, page 264. The Applicant has now found that it is possible to use, for cosmetic treatment linked to the inhibition of body odour, alkyl esters combined with various cosmetic carrying agents, obtaining a considerable reduction in body odour without eliminating the resident bacterial flora, thus keeping the protective defences of the organism intact and eliminating the disadvantages of traditional deodorants.
