When preparing the cream, use the following schematic diagram. When heated, the required amounts of spermaceti, stearin, sperm whale fat alcohols, crystalline spermacea are mixed to form a fatty base. Olive oil, stone seed oil, triethanolamine, nipagin, glycerin, a fat base and water are mixed to obtain an aqueous base with further emulsification at a temperature of 60-80 ^o C. The resulting intermediate is cooled to 35-45 ^o C and ethanol is introduced into it with stirring, perfume and a concentrate of vitamin A and / or a dietary supplement mummy. Cool the product with constant stirring, followed by crystallization of the finished product.

 The invention will be further illustrated by the following implementation examples.

Example 1. In an enameled boiler equipped with a steam jacket, load 17.5 kg of spermaceti, 3.5 kg of crystalline spermacea, 15.4 kg of cosmetic stearin, 14.0 lanolin and 9.1 kg of hydrogenated sperm whale alcohols. The loaded products are melted at a temperature of 70-80 ^o C. The molten fat base is pumped with simultaneous filtration into a digester. With constant stirring, 1.4 kg of nipagin are dissolved in 15 kg of water in a separate container. The dissolution is carried out at a temperature of 25-30 ^o C. 25.2 kg of glycerol are added to the solution. After mixing and filtration, the solution is fed into the digester. The digester is charged with the remaining water (approximately 556 kg), 17.5 kg of olive oil, 9.1 kg of triethanolamine, as well as the previously obtained fat base and emulsification is carried out for 15-25 minutes at a temperature of 65-80 ^o C. The emulsion is pumped into the refrigerator and, with constant stirring, cooled to a temperature of 30-50 ^° C. Then, with constant stirring, 7.0 kg of ethyl alcohol, 3.5 kg of perfume and 5.6 kg of vitamin A are introduced. The cream is cooled with constant stirring to a temperature of 25 -40 ^o C, turn off the stirring and cooling and leave the cream d For crystallization for 10-14 hours. After crystallization, the product is dispensed for packaging.

Example 2. In an enameled boiler equipped with a steam jacket, load 19.3 kg of spermaceti, 3.8 kg of crystalline spermacea, 16.1 kg of cosmetic stearin, 14.9 lanolin and 8.9 kg of hydrogenated sperm whale fatty alcohols. The loaded products are melted at a temperature of 70-80 ^o C. The molten fat base is pumped with simultaneous filtration into a digester. With constant stirring, 1.6 kg of nipagin in 15 kg of water are dissolved in a separate container. The dissolution is carried out at a temperature of 25-30 ^o C. To the solution add 26.4 kg of glycerol. After mixing and filtration, the solution is fed into the digester. The digester is charged with the remaining water (approximately 556 kg), 18.9 kg of stone seed oil, 8.1 kg of triethanolamine, as well as the previously obtained fat base and emulsification is carried out for 15-25 minutes at a temperature of 65-80 ^o C. The emulsion is pumped into the refrigerator and, with constant stirring, cooled to a temperature of 30-50 ^o C. Then, with constant stirring, 8.2 kg of ethyl alcohol, 3.5 kg of perfume, 1.4 kg of vitamin A and 4.7 kg of biologically active additives mummy .

The cream is cooled with constant stirring to a temperature of 25-40 ^o C, turn off the stirring and cooling and leave the cream for crystallization for 10-14 hours. After crystallization, the product is transferred to the packaging.

The resulting product meets the characteristics given in the table.
When conducting a study of the resulting cream, it was applied to areas of the skin of people with different susceptibilities to solar radiation. It was experimentally established that, regardless of the initial susceptibility of the skin of the participants in the experiment to the action of solar radiation, a cream layer, the composition of which is the declared one, protects the skin of the participant in the experiment for an average of 2.7 hours relative to the skin areas not protected by the cream.
