Abstract: An improved process for preparing factor VIII concentrate which comprises a first stage wherein fibrinogen is precipitated from a buffered plasma or plasma cryoprecipitate solution by the addition of a polyol and a second stage where factor VIII is precipitated from the resulting supernatant also by the addition of a polyol. The improvement in the first stage resides in adding the polyol in an amount of 1-3% and maintaining the temperature of the buffered solution between about 2.degree.-4.degree. C.

Abstract: A process for reducing the volatility and improving the emulsifying power of an unsaturated or saturated cosmetic oil comprising heating the cosmetic oil, in the absence of a solvent and under an inert atmosphere, with a homopolymerizable and hydrophilic monomer in the presence of an initiator generating free radicals. The monomer is selected from the group consisting of N-vinylpyrrolidone, 2-hydroxymethyl acrylate, 2-hydroxymethyl methacrylate, acrylamide, methacrylamide, N-hydroxymethyl acrylamide, N-(carboxyhydroxy) methacrylamide, acrylic acid, methacrylic acid, 2-vinylpyridine, 4-vinylpyridine and a monomer having the formula, ##STR1## wherein R is hydrogen or methyl, Y is O or NH, r' is methyl or ethyl and n is 2 or 3. The resulting modified oil is then purified to remove any insoluble nongrafted homopolymer.
Abstract: A stable oil-in-water emulsion for use in cosmetic or pharmaceutical compositions includes as the emulsifying system therefor a combination of (i) a mixture of (1) mono- or di-alkyl carboxylates of .alpha.-methyl glucoside, or a mixture thereof and (2) mono- or di-alkyl carboxylates of .alpha.-methyl glucoside polyoxyethylenated with 10-30 moles of ethylene oxide, or a mixture thereof, the said alkyl moiety of each being linear or branched and having from 11-21 carbon atoms, (ii) lecithin, (iii) egg yolk oil, and (iv) a polyacrylic type polymer.
