This cream allows you to improve the softening and tonic properties.

Closest to the proposed cream is disclosed in the copyright certificate SU 806036. This cream contains the following components in wt.%:

Olive oil 9-11 Lanolin 1.5-2.5 Cacao butter 1.5-2.5 Glycerol 4-6 Hydrogenated alcohols sperm whale fat 1.5-2.5 Emulsion Waxes 6-8 Sea buckthorn carbon dioxide extract 0.2-1.5 Ethanol 2-4 Paraoxybenzoic acid methyl ester 0.1-0.2 Paraoxybenzoic acid propyl ester 0.01-0.1 Perfume 0.5-1.5 Water rest

This well-known cream can improve fat metabolism and vascular permeability.

However, all known creams do not allow to achieve a complex effect, including easy application of the cream, good absorbent effect, giving the skin a silkiness, moisturizing the skin, active regeneration of skin cells and preventing its aging processes.

The objective of the invention is to achieve a comprehensive effect on the skin, including easy application of the cream, good absorbent effect, giving the skin a silky feel, moisturizing the skin, active regeneration of skin cells and preventing its aging processes.

The problem is solved in that the cosmetic cream containing olive oil, lanolin, glycerin, carbon dioxide extract of sea buckthorn, perfume and water, additionally contains triethanolamine, a mixture of cetetareth-6 and stearyl alcohol, stearic acid, cetearyl alcohol, mink fat, ethyl hexamethoxyl methylene hexyl methyl and ethyl hexyl methoxide hydrocarbon, in the following ratio of components, wt.%:

A mixture of ceteareth-6 and stearyl alcohol 0.1-0.8 Stearic acid 0.5-5.0 Triethanolamine 0.2-1.5 Cetearyl alcohol 0.1-1.0 Mink Fat 0.2-7.0 Olive oil 1.0-10.0 Lanolin 0.1-1.0 Ethylhexyl methoxy cinnamate 0.1-1.0 Sea buckthorn carbon dioxide extract 0.05-0.8 Glycerol 0.5-10.0 Perfume 0.05-1.0 Hydrocarbon propellant 2.0-15.0 Water rest.

In private embodiments of the invention, the problem is solved in that as a carbon dioxide extract of sea buckthorn contains a supercritical extract.

The invention consists in the following.

Thanks to aerosol packaging, it was possible to create a modern cream formula without preservatives, eliminating their negative effect on the skin.

The components of the cream and their content are selected in such a way as to obtain a cream with a gentle, airy texture that is easy to apply, quickly absorbed, making the skin smooth like silk, and the oils contained in it, sea buckthorn extract and UV filter perfectly moisturize the skin, slow down the processes premature aging, activate cell regeneration.

The supercritical (SC) CO ₂ extract of sea buckthorn has an anti-inflammatory effect, normalizes water-fat metabolism in skin cells. Relieves irritation of inflamed skin.

By the supercritical extract of sea buckthorn is meant the carbon dioxide extract of sea buckthorn obtained by extraction at supercritical pressure. It is delivered in accordance with the requirements of TU 9154-001-51585120-01.

As a mixture of ceteareth-6 and stearyl alcohol (ceteareth-6 and stearyl alcohol), Cremophor A6 is used, which in the cream acts as an emulsifier.

Stearic acid together with triethanolamine, supplied according to TU 6-09-2428-91, also act as an emulsifier.

As cetearyl alcohol, Lanette D. is used.

In cream, cetearyl alcohol (Lanette D) is a structure-forming component.

Mink fat contains a large amount of polyunsaturated fatty alcohols, due to which it has a regenerating, moisturizing and softening effect. Contains a natural UV filter. Of all known fats, mink fat has the greatest penetration into the skin. Contains Vitamin E Derivatives. Prevents peeling and aging.

Lanolin is an excellent skin softener. In the emulsion is a structure-forming component.

Ethylhexyl methoxycinnamate (ethylhexyl methoxycinnamate), which is used Uvinul MC 80, protects the skin from the harmful effects of ultraviolet B rays.

Vegetable oil, which is used as olive oil, contains about 84% oleic acid and cholesterol, which ideally optimize lipid metabolism in the skin, increase the level of hydration in the epidermis.

Glycerin is a moisturizing component. The claimed composition of the cream uses dynamite glycerin D 98 in accordance with GOST 6824 or supplied by import.

Hydrocarbon propellant - propellant of the active product.

Demineralized water is used as a solvent in accordance with STP 00204263-58-99.

Fragrance gives a pleasant smell to the product.

The invention is as follows.

To prepare the cream, a prescription amount of demineralized water is pumped into the reactor with a volume of 1.6 m ³ through the meter, then glycerin is loaded with a submersible pump, manually - triethanolamine.

Include a mixer (30-40 rpm) and heating. The contents of the reactor are heated to a temperature of 75-80 ° C. Turn off the stirrer.

Отключают мешалку и воду.In parallel, in the other reactor with a volume of 2.0 m ^3, manually calculated quantities are loaded manually through the hatch: olive oil, stearic acid, lanolin, Lanette

, mink fat, Cremophor A6. Include a mixer (30-40 rpm) and heating. The contents of this reactor are heated to a temperature of 75-80 ° C, stirred until the components are completely dissolved and the contents of the first reactor are fed into it. Turn off the heating. The homogenizer is turned on (homogenization parameters are approved during the preparation of experimental batches) and emulsified for 30-40 minutes. When the emulsion reaches a temperature of 45-50 ° C, the carbon dioxide extract of sea buckthorn is manually loaded, Uvinul MS 80, mixed for 20-25 minutes. Then cold water is fed into the jacket of the reactor, when the temperature reaches 40 ° C, the recipe amount of perfume is manually loaded. The contents are mixed for 15-20 minutes. Turn off the stirrer and water.

Then take a sample of the product to check the physico-chemical and microbiological parameters. With a positive conclusion from the laboratory, the finished product at a temperature of 40 ° C is pumped by a membrane pump into a mobile heated reactor with a stirrer (15-20 rpm), the temperature of which is maintained at 40 ° C and fed to the filling line.

During the entire preparation and packaging of the cream emulsion, the product temperature is maintained at 40 ° C.
