Description

 The invention relates to cosmetology, in particular to cosmetics for the care of facial skin.

 A well-known skin cream containing petroleum jelly, sperm whale salomat, lanolin, cosmetic stearin, VNIIZh emulsifier, borax, vitamin A concentrate, chamomile water extract, vitamin D concentrate, eucalyptus oil, benzyl alcohol, benzyl acetate and crystalline menthol (see. Cream "Children's" , OST 18-21-70).

 The cream does not have sufficient absorbency and cannot serve as the basis for makeup.

 A well-known face cream containing a mixture of water and ethanol extracts of flower pollen, glycerol monostearate, olive oil, glycerin, stearin, emulsion waxes, triethanolamine, ethyl alcohol, methyl and propyl esters of paraoxybenzoic acid, perfume and water (see A.S. 99205757 , CL A 6l K 7/00, 02/05/83).

 Known cream is closest to the proposed cream in its constituent components. However, it has a fairly high fat concentration, which makes it unsuitable for use under makeup.

 The proposed cream has high protective functions and hygroscopic properties.

 This is achieved by the fact that the cream for makeup containing stearin, glycerin, triethanolamine, perfume and water, additionally contains high molecular weight alcohols, VNIIZhemulgator and polyvinyl alcohol in the following ratio of components, wt. stearin 5.5-6.5; triethanolamine 0.25-0.35; high molecular weight alcohols 2.8-3.1; glycerol 7.0-8.0; VNIIHemulsifier 2.5-3.0; polyvinyl alcohol 0.25-0.35; perfume 0.1-0.5; water the rest.

 The introduction of high molecular weight alcohols and VNIIZH emulsifier into the cream formulation creates an additional emulsifying effect, which improves the consistency of the cream.

 The introduction of polyvinyl alcohol in the formulation provides high hygroscopic properties of the cream, which increases its protective functions.

 Cosmetic stearin and triethanolamine, which form triethanolamine stearate during the interaction, are introduced in the cream formulation as an emulsifying component and a structurant. The introduction of cosmetic stearin and triethanolamine below the lower limit, respectively 5.5% and 0.35%, does not give a sufficient emulsifying effect, and the introduction above the upper limit, respectively 6.5% and 0.35%, creates a rigid structure.

 High molecular weight alcohols and VNIIZH emulsifier are used as primary emulsifiers, the introduction of which is below the lower limit, respectively 2.8% and 2.5%, does not provide optimal primary emulsification, and the introduction above the upper limit, respectively 3.1% and 3.0% creates a tough structure.

 As a softening component, glycerin is introduced into the cream formulation, the content of which below the lower limit of 7.0% does not provide a softening effect, and the introduction of above the upper limit of 8.0% creates an excessive effect.

 As a protective film-forming component, polyvinyl alcohol is introduced into the formulation, the content of which below the lower limit of 0.25% does not provide the protective functions of the cream, and the introduction of above the upper limit of 0.35% affects the hygroscopic properties of the film.

 As a component that creates an odor, a fragrance is used, the introduction of which below the lower limit of 0.1% does not provide a pleasant smell, and the introduction of above the upper limit of 0.5% creates a pungent odor.

 As part of the makeup cream, the minimum, optimal and maximum limits of the formulations (wt.) Are taken. See table.

 The technology for preparing the cream consists of the following technological operations.

Drinking water is poured into the digester to the required mark. Steam is supplied to the boiler jacket for heating. Cosmetic stearin of grades “A”, “B”, “D”, “U” is loaded into water heated to 70-80 ^o C, triethanolamine, 0.3 kg high molecular weight alcohols 3.0 kg, glycerol 7.5 kg and VNIIZHEMULGATOR 2.7 kg. When the components are completely melted, they turn on the boiler mixer and begin to emulsify the mass, driving it by a centrifugal pump for circulation. After 15 minutes of emulsification, the centrifugal pump is turned off, steam is shut off and, without turning off the stirrer, cooling water is supplied to the boiler jacket. When the cream mass reaches a temperature of 60 ^o C, 0.3 kg of polyvinyl alcohol is introduced into it and, without stopping cooling, it is homogenized with a centrifugal pump for another 5 minutes. At the same time, a fragrance of 0.3 kg is introduced into the cream. When the cream reaches a temperature of 50-40 ^o With it is pumped out of the boiler. When the cream sample reaches a temperature of 35-25 ^o C, a physicochemical analysis is carried out.

 After the analysis meets the technical requirements for this cream, it is sent for packaging.

 The proposed cream is intended to protect the skin when applying makeup, when using forms a smooth and easily washable absorbent film. The cream is plastic, easily lays on the skin, does not cause an irritating effect. The cream is simple in composition and technologically advanced to manufacture. It can be used as a basis for day and evening makeup. TTT1
