Compounds of the formula I ##STR1## where the individual radicals R are identical or different and are each hydrogen, an alkali metal, or ammonium which is unsubstituted or substituted by organic radicals, or are each C.sub.1 -C.sub.20 -alkyl or a polyoxyethylene radical which contains from 1 to 10 ethylene oxide units and whose terminal OH group may be etherified by an alcohol of 1 to 3 carbon atoms, are used as sun screen agents.

Cosmetic formulations containing oxyethylated diphenylamines as sun

A process for the preparation of high-viscosity polyvinylpyrrolidone, wherein an aqueous polyvinylpyrrolidone solution is subjected to a heat treatment in the presence of a water-insoluble peroxide and in the absence of oxygen, and thickeners containing the polyvinylpyrrolidone thus prepared.

Compounds of the formula I ##STR1## where R is a polyethylene glycol radical of 3 to 60 chain members or a polypropylene glycol radical of 3 to 60 chain members or the radical of an ethylene oxide/propylene oxide block polymer of average molecular weight from 300 to 8,500, and R' is straight-chain or branched alkyl of 1 to 10 carbon atoms, or benzyl.

Polyalkoxycarbinol cinnamates and protective sun agents containing these

Water-in-oil emulsifiers are obtained by reacting fatty alcohols with epichlorohydrin and reacting the resulting glycidyl ethers with amine.

Manufacture of water-in-oil emulsions

A process for the manufacture of reaction products of fatty alcohols and epichlorohydrin, which have been reacted with polyhydric alcohols or their monoethers and may or may not have been further modified with alkylene oxides, the reaction products per se and emulsifiers, solubilizing agents and fat-like materials consisting of these products.

Production of water-in-oil emulsions

A process for the manufacture of copolymers by copolymerizing acrylic acid or methacrylic acid with esters of acrylic acid and methacrylic acid in the presence of polymerization initiators, in which methyl methacrylate, acrylic acid and/or methacrylic acid and a higher alkyl acrylate are copolymerized.
