Title: Solubilizing of mineral, vegetable and animal oils for cosmetic and industrial purposes
IPC: A61K8/34
Filed: 1955-08-02
Abstract: Mineral, vegetable and animal oils are made miscible with and solubilized in a C1-C4 monohydric aliphatic alcohol by means of a solubilizer comprising a C10-C24 aliphatic alcohol and/or acid in amount from 5-30 per cent of the solubilized composition, the oil and monohydric alcohol constituting substantially the whole of the balance such that the monohydric alcohol constitutes 20-40 per cent of the composition and the oil constitutes 15-40 per cent of the composition.  The fatty acids and/or alcohols comprising the solubilizer may be saturated, unsaturated or hydroxylated.  The fatty alcohol forms preferably the major part of the solubilizer composition. Specified fatty alcohols include lauryl, oleyl, stearyl, palmityl, linoleyl, linolenyl, ricinoleyl, myristyl and arachidyl alcohols: the corresponding fatty acids are also specified.  Oils specified include light and heavy mineral oil, sesame, cotton seed, soybean, sunflower, corn, peanut, sweet almond, apricot, peach kernel, safflower, olive, pine, palm, neatsfoot, sperm, lanolin, bone and cod liver oils.  Essential oils may also be included as an additional ingredient.  Solubilizer compositions exemplified include mixtures comprising lauryl alcohol, linolenic acid and oleyl alcohol; palmityl alcohol, lauryl alcohol, oleyl alcohol, oleic acid and ricinoleic acid; oleyl alcohol and oleic acid; oleic acid and linoleic acid; and linoleic acid and oleyl alcohol. Examples are given of solubilized compositions.  Permanent waving preparation.-To the solubilized composition is added thioglycollic acid salts, polyvinyl-pyrrolidone and casein (protein hydrolysates).ALSO:Mineral, vegetable and animal oils are made miscible with and solubilized in a C1-C4 monohydric aliphatic alcohol by means of a solubilizer comprising a C10-C24 aliphatic alcohol and/or acid in amount from 5-30 per cent of the solubilized composition, the oil and monohydric alcohol constituting substantially the whole of the balance such that the monohydric alcohol constitutes 20-40 per cent of the composition and the oil constitutes 15-40 per cent of the composition.

Examples are given of solubilized compositions.  A superfatted soap may be made by adding the composition to a transparent soap mixture comprising an alkali, fatty acid, alcohol and glycerine.ALSO:Mineral, vegetable and animal oils are made miscible with and solubilized in a C1-C4 monohydric aliphatic alcohol by means of a solubilizer comprising a C10-C24 aliphatic alcohol and/or acid in amount from 5-30 per cent of the solubilized composition, the oil and monohydric alcohol constituting substantially the whole of the balance such that the monohydric alcohol constitutes 20-40 per cent of the composition and the oil constitutes 15-40 per cent of the composition.

Cosmetics.-In preparing cosmetics there may be added to the solubilized composition lanolin derivatives, antiseptics, rubefacients, estrogenic hormones, methyl sulphoxide and solubilized amino acids to make hair lotions: aluminium, zinc and zirconium salts, silicones and deodorants such as hexachlorophene to make an antiperspirant composition; alcohol soluble silicones (dimethyl polysiloxanes), lanolin derivatives and antiseptics to make a silicone protective composition: antiseptics, astringents, and antibiotics such as tyrothricin, neomycin and bacitracin to make an after-shave lotion; sulphur, resorcinol, salicylates, organic sulphides and acetamides to make an anti-dandruff lotion; silicones, polyvinyl-pyrrolidone, casein and lanolin derivatives to make a hair lacquer preparation; and para-aminobenzoic acid to make a sun screening preparation.  Medicinal preparations.-In addition to the anti-dandruff preparation above, a preparation for use against acne may be prepared by adding to the solubilized composition sulphur compounds, polysulphides, resorcin, Vitamins A-D and antibiotics such as tyrothricin, neomycin and bacitracin may be added.  Fungicidal and insecticidal preparations.-To prepare a fungicide, salicylic and benzoic acids, and acids such as propionic, undecylinic, caprylic and thioglycollic, and their salts; and to prepare an insecticide preparation compounds such as 2 : 4-hexanediol and dimethyl phthalate may be added to the solubilized composition.
