Tetraaminopyrimidines as developers in oxidation hair dyes - esp. used with meta aminophenol couplers for blue shading dyes

Abstract: Oxidn. hair dyeing compsns. contain as developer tetraaminopyrimidines of formula (I) or their salts or mixts.; (where R1-R6 = H, 1-4 C alkyl or -(CH2)nX; n = 1-4; X = OH, halo, NH2, NHR1 or NR1R11; R1 and R11 = 1-4 C alkly or together complete a heterocycle opt. contg. a further O or N; opt. substd. aryl or opt. substd. 5 or 6 membered heterocycles contg. 1 or 2 N atoms or 1N plus 1 O). (I) give intense colours varying from blond to dark brown and from green to violet; they are highly sol. in water, storage stable, are non-toxic and do not irritate the skin or mucosa. Dyeings are stable to light, washing and abrasion, but may easily be removed with reducing agents.

Alkyl Polyglycosides-Properties and Applications of a new Class of Surfactants.

Abstract: A new generation of nonionic surfactants that are widely applicable and simultaneously ecologically compatible has been developed in the alkyl polyglycosides. Their production from the renewable resources glucose and fatty alcohol and their ultimate biodegradation into carbon dioxide, water, and assimilated bacterial biomass is an example for a closed cycle. As a result of their physico-chemical properties and ecotoxicological evaluation, they have become very important as high-performance components of detergents and cosmetic preparations.

Quaternary ammonium compounds

Abstract: Quaternary ammonium compounds corresponding to the formula ##STR1## are produced by esterification of ether amines corresponding to the formula ##STR2## with a fatty acid of the formula R 2 --COOH and quaternization of the product obtained with an alkyl halide or a dialkyl sulfate. They are suitable for use as conditioning and revitalizing agents in hair-cosmetic preparations.

Surface-active compositions, especially cosmetics, containing glycerol carbonate as emulsifier

Abstract: The use of glycerol carbonate (I) is claimed as: (i) an emulsifier for the preparation of surface-active compositions; (ii) a replacement for silicone oil in cosmetic and/or pharmaceutical compositions; or (iii) a brightening agent in the preparation of cosmetic compositions.
