Abstract: The present invention provides an oil-in-water or water/oil/water multiple emulsion, or a mixture thereof, comprising (A) a organopolysiloxane elastomer crosslinked with polyether chains and (B) at least one thickener selected from the group of a polyacrylamide homo- or copolymer, a cellulose ether, a non-silicone cationic polymer or a thickening system comprising a mixture of from about 60% to about 67% of the thickening system of a copolymer of 2-propenoic acid with 2-propenamide, from about 27% to about 32% of the thickening system of the homopolymer of 2-methyl-1-propene and from about 5 to about 7% of the thickening system of poly(oxy-1,2-ethanediyl)-sorbitan-monododecanoate.

Abstract: The invention relates to the use of creatine, creatinine and/or derivatives thereof and/or their salts in an agent for hardening, strengthening, restructuring or increasing the shine, volume or combability of keratin fibers, particularly of human hair.

Abstract: A process for manufacturing hair cosmetic or skin cosmetic products is described, in which the products contain a preparation with hair cosmetic or skin cosmetic ingredients and one process step includes conducting at least a part of the preparation through an apparatus with microstructured units. The apparatus with microstructured units can be one or more static micromixers and/or one or more microheat exchangers.

Abstract: The composition for hardening, strengthening and restructuring keratin-containing materials and/or for increasing the volume of keratin-containing fibers, such as hair, contains from 0.3 to 50.0% by weight of one or more reductones, each having a —(HO)C═C(OH)— group. The reductone ingredient is preferably ascorbic or isoascorbic acid, a salt of ascorbic or isoascorbic acid, such as an alkali metal or alkaline earth metal salt, an ester of ascorbic or isoascorbic acid, 6-O-palmitoyl ascorbate, ascorbyl phosphate, 2,3-dihydroxy-2-propenal and hydroxypropanedial. A method of treating keratin-containing materials or fibers to harden, strengthen and restructure keratin-containing materials and/or to increase the volume of the keratin-containing fibers by applying this composition and allowing it to act is described. A method of pre-treating keratin-containing material that is to be subjected to a chemical or physical treatment, such as dyeing or permanent shaping is also described.
