Description

one

The invention relates to the cosmetic industry and concerns the production of aerosol cosmetic products that serve for decorative purposes and are beneficial to the skin.

A means of artificial tanning in the form of lotions containing dioxyacetone as an active substance is known. The composition of these lotions also includes ethyl alcohol, karyon F-liquid non-hygroscopic humidifier, iso-adipate, distilled hemamelis, orange or pink water, alantoin, castor oil, p-hydroxybenzoic acid methyl ester, fumigation, boron acid, distilled water 1.

The closest in technical essence to the present invention is an artificial agent, a tanning agent containing dioxyacetone, p-hydroxybenzoic acid methyl alcohol, citric acid, otdushku and water 2.

The disadvantages of the agent are the absence of substances that nourish the skin, make it smooth and velvety, as well as those emulsifiers and structure-forming substances that lead to

creating a consistency that ensures even distribution of the composition when applied to the body and good absorption of the tanning agent. The purpose of the invention is a uniform distribution of tanning and improved softening properties.

This goal is achieved by the fact that an artificial tanning agent containing dioxyacetone, p-hydroxybenzoic acid methyl ester, citric acid, otdushku and water, additionally contains olive oil, isopropyl myristate, highly purified petroleum paraffins, cremophors AB and A-25, p-hydroxybenzoic acid propyl ester, ceresin, emulsion waxes and propellant in the following ratio of components, wt.%: Olive oil 0.5-5.0

Dioxyacetone (НО-СН2-С-CHj-ОН) was introduced into the formulation as an active component; reacting with the amino acids of the epidermis, forming a compound of yellowish-brown color, imitating the color of the sun tan.

The tan color at pH below 4 decreases dramatically, at pH 7 skin coloring is weak, and at pH 8 it disappears completely. To create a weakly acidic environment (the optimum pH, which provides the maximum reactivity of dioxyacetone and is more appropriate for the pH of human skin, should be in the range of 5-6), citric acid in the amount of 0.005-0.007% is introduced into the formulation of this cosmetic. The recipe also contains the minimum amount of linoid substances slowing down the reaction.

Substances that contain amino groups that react with dioxyacetone are excluded, as a result of which the cosmetic preparation itself is colored and its consumer properties are reduced, as the concentration of dioxyacetone in the preparation is reduced.

In order to ensure the maximum reactivity of dioxyacetone, nonionic emulsifiers — Cremophore / 6–6 (product, reacting 6 molecules of ethylene oxide and 1 molecule of high molecular weight alcohols) in the amount of 1.7–2.5% and cremophor A-25 were selected for creating a cosmetic emulsion. (obtained by the interaction of 1 molecule of higher fatty alcohols and 25 molecules of ethylene oxide), in an amount of 0.2-0.35%, which combine well with waxes. In order to create a stable emulsion system, emulsion Waxes are introduced into the formulation, obtained by fusing hydrogenated distilled high molecular weight sperm whale fat with potassium salts of phosphoric esters of hydrogenated high molecular weight alcohols in the amount of 0 ,. .

The preservatives used are p-hydroxybenzoic acid propyl ester in an amount of 0.02-0.05% and p-hydroxybenzoic acid methyl ester in an amount of 0.09-0.15%.

Olive oil in the amount of 0.5-5% is introduced into the formula of the dopic agent as a skin-nourishing component, isopropyl myristate in the amount of 1.0-6.0% is used as plasticizers, highly purified petroleum paraffins in the amount of 0.5-3%

(the latter serve as a structure-forming component). Ceresin was also used as a structure-forming substance to create the drug of optimal consistency. In order to flavor the cream, a perfume in the amount of 0.3-0.6% was used.

A mixture of freon 12 and 114 in the ratio 4: 6 was used as the propellant. The propellant is introduced into the composition in the amount of 8-12%.
