  • Patent number: 3934003
    Abstract: The present disclosure relates to a water-soluble and fat-restoring cosmetic and medicinal preparation comprising an ethoxylated glyceridic mixture of saturated vegetable fatty acids of about 8 to 14 carbon atoms, the glycerides of said acids having chemically linked thereto about 2 to 8 moles of ethylene oxide per free hydroxyl group. These substances may be admixed with other ingredients to form, for example, a hair tonic, an oil shampoo, a nutrient skin milk, a skin cream, a bath oil or sun tan oil. The ethoxylated mixture is preferably formed by reacting ethylene oxide at about 100.degree.-150.degree.C. with a glyceridic mixture having a fatty acid composition comprising caprylic acid, capric acid, lauric acid and myristic acid.
