Description

The invention relates to cosmetology, in particular to cosmetic nourishing and moisturizing creams, and is intended for the effective care of dry, aging facial skin.

The patent RU 2063743 discloses a cosmetic cream containing the following components in wt.%:

Derivative of space-hindered phenols 0.5-5.0 Natural fat 11.0-22.5 Ginseng Water Alcohol Glycerin Extract 1.5-6.5, Derivatives of Polyhydric Alcohols 2.0-23.0 Glycerol 4.0-10.0 Perfume 0.3-1.0 Preservative 0.1-0.7 Emulsifier 7.0-12.0 Water Rest

This invention allows to improve the biological and physiological properties of the skin, effectively preventing its aging, and provide a protective effect.

Closest to the proposed cream is disclosed in the copyright certificate RU 2017481. This cream contains the following components in wt.%:

Cosmetic stearin 2-6 Distilled monoglycerides 1-3 Sunflower oil 5-15 Glycerol 2-8 Dietary supplement from ginseng biomass - strain R-1 1-5 Ethanol 0.5-4.0 Triethanolamine 0.2-2.0 Perfume 0.05-1.5 Hydrocarbon propellant 10-20 Water Rest

This well-known cream has a delicate texture, is well absorbed by the skin, softens it, the fine network of wrinkles disappears.

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, slowing premature aging of the skin, improving the complexion, providing the skin with proper nutrition and protection, as well as its regeneration.

The objective of the invention is to achieve a comprehensive effect on the skin, including easy application of the cream, good absorbency, giving the skin a silky feel, slowing premature aging of the skin, improving complexion, providing the skin with adequate nutrition and protection, as well as enhancing the regenerative ability of the skin.

The problem is solved in that the cosmetic cream containing vegetable oil, triethanolamine, glycerin, ginseng supplement, fragrance, propellant and water, additionally contains a mixture of ceteareth-6 and stearyl alcohol, stearic acid, cetearyl alcohol, caprylic / trigroic acid, triglyceride fatty acid and ethylhexyl methoxy cinnamate, and as a ginseng-containing additive, ginseng water-alcohol extract, in the following ratio, 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 Caprylic / Caproic Acid Triglyceride 0.2-5.0 Mink Fat 0.2-7.0 Vegetable oil 1.0-10.0 Ethylhexyl methoxy cinnamate 0.1-1.0 Hydroalcoholic Ginseng Extract 0.2-3.0 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 vegetable oil, the cream contains extra virgin olive oil.

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 contents 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 natural oils and ginseng extract and UV filter contained in it slow down premature aging, improve complexion, provide the skin with full nutrition and protection.

Ginseng water-alcohol extract has a tonic effect on the skin, promotes wound healing, improves blood circulation and intracellular metabolism. It is delivered in accordance with the requirements of TU 9389-002-10488286-92 or FS 42-1886-82.

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.

Caprylic / capric triglyceride triglyceride (caprilic | capric triglyceride), which uses Rofetan GTCC emollient, gives the skin softness and velvety, is a plasticizer and improves the appearance of the cream mass.

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.

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.

At the same time, in the other 2.0 m ³ reactor, manually calculated quantities are loaded manually through the hatch: olive oil, stearic acid, Rofetan, Lanette D, 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, manually load the ginseng water-alcohol extract, Uvinul MS 80, mix 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.

As follows from table 4, revealed a high medium-lasting moisturizing effect.

The cream also has a pronounced generating effect, as evidenced by an increase in the number of collagen fibers and functionally active cells - fibroplasts that produce endogenous collagen and elastin to form a collagen skeleton of the skin, providing its elasticity and elastic properties.

An increase in the number of sebaceous glands was also noted, which indicates a stimulating effect of the drug on the appendages of the skin.
