     Skin care products
As the skin ages, there is a loss of elasticity and a reduction in turgor, as a result of which wrinkles and wrinkles appear. So far it has not been possible to counteract these signs of aging on a cosmetic basis in a satisfactory manner.



   It has now been found that sphingolipoids have a beneficial influence in this direction. The term sphingolipoids is understood as meaning lipoids which contain sphingosine or dihydrosphingosine as a base and which preferably occur in the nerve tissues. A distinction is made between sphingamidylphosphocholines or sphingomyelins, which are made up of a fatty acid, phosphoric acid, choline and sphingosine or dihydrosphingosine, and cerebrosides or glycosidosphingosides, which apart from spingosine or dihydrosphingosine contain fatty acid and a sugar in a glycoside bond, but no phosphoric acid. Sphingolipoids can e.g. B. obtained from ox brain [J. Biol. Chem.



  169, 77 (1947)].



   The mentioned sphingolipoids increase the turgor of the skin and give it a velvety, pleasant feeling after just a short application. While the sphingolipoids counteract the formation of wrinkles and wrinkles in old skin, they give young skin a feeling of freshness. Even in higher concentrations, they do not cause any irritation.



   The invention accordingly relates to a skin care product which contains one or more sphingolipoids as a component. The sphingolipoids are expediently used in concentrations of 0.1-25 / o. Suitable carriers are all substances customary in cosmetic preparation forms, such as ointments, creams, lotions, etc., e.g. B. wool fat, higher fatty alcohols, waxes, vegetable oils, petroleum jelly.



   example 1
Face and hand lotion
1.00 g isopropyl palmitate,
0.50 g of 1, 2, 3-trihydroxy-3, 7, 11, 1 5-tetramethylhexadecane (produced by treating
Isophytol with performic acid and saponification of the reaction product with caustic soda),
0.60 g of oxethylated fatty alcohol,
0.25 g of cetyl alcohol,
0.50 g panthenol,
0.25 g acetostearate and 0.50 g isophytol are heated to 70 ". Under
Stir a suspension of
1.00 g of sphingolipoids in 20.00 g of a 10 / above aqueous polyacrylic acid solution emulsified with the fatty phase. In the emulsion is a solution that
Contains 5.00 g glycerine and 70.00 g water, incorporated at 500 C. The desired viscosity is set by adding arginine.

   The lotion can be perfumed and colored as desired.



   Example 2 fat cream 10.00 g stearin,
2.00 g of cetyl alcohol,
2.00 g wool fat,
4.00 g beeswax, 10.00 g almond oil,
5.00 g 1, 2, 3-trihydroxy-3, 7, 1 1, 15-tetramethylhexadecane,
5.00 g of oxethylated fatty alcohol, 10.00 g of perhydrosqualene and
5.00 g of glycerol monostearate are heated to 700 C. An aqueous suspension of is in the melt with stirring
3.00 g sphingolipids,
2.00 g of oxyethylated fatty alcohol and 42.00 g of water are incorporated at 600.degree.



   The cream can be perfumed as desired.



   Example 3
Gel for the treatment of oily skin
3.00 g of sphingolipids are mixed with 97.00 g of a 20% polyacrylic acid solution at 500.degree. Then with a basic amino acid, z. B. arginine, the ge desired consistency set.
