  • Patent number: 12403074
    Abstract: Present invention relates to a process for permanent waving keratin fibers, especially human hair, for achieving durable waves wherein fibers are treated with a reducing composition, a non-reducing and non-oxidizing alkaline composition, a non-reducing and non-oxidizing acidic composition and finally an oxidizing composition wherein after processing the reducing composition the fibers are rinsed off.

  • Publication number: 20240197595
    Abstract: Cosmetic compositions for keratin fibers, kits-of-parts comprising the cosmetic compositions, and keratin fiber reshaping processes are disclosed herein. The cosmetic compositions have a pH in the range of 7 to 12 and comprise one or more organic alkalizing agent(s) and one or more particulate thickening agent(s), wherein the cosmetic compositions comprise less than 1% by weight of oxidizing agents, calculated to the total weights of the cosmetic compositions.

  • Publication number: 20170000700
    Abstract: A hair bleaching process reduces hair damage to bleached hair and comprises the steps of (i) preparing an aqueous bleaching composition by mixing three compositions (a), (b) and (c), wherein the composition (a) is a substantially anhydrous composition comprising at least one compound with bleaching effect, the composition (b) is an aqueous composition comprising at least one oxidizing agent, and the composition (c) comprises at least one compound selected from the group consisting of water soluble silk protein, water soluble silk protein hydrolysate and of derivatives of water soluble silk protein and water soluble silk protein hydrolysate, (ii) reducing cysteic acid content and formation in bleached hair by applying the aqueous bleaching composition onto hair and (iii), after processing of 5 to 45 min at a temperature in the range of 20 to 45° C., rinsing the aqueous bleaching composition off from the hair.

  • Publication number: 20120024309
    Abstract: The present invention relates to bleaching composition for keratin fibres, especially human hair, comprising at least one compound with bleaching and/or highlighting effect wherein a water soluble protein selected from water soluble silk protein, water soluble silk protein hydrolysate and their derivatives is added. The object of the present invention is aqueous composition for bleaching hair comprising three parts which are mixed prior to application onto hair and which are a—a substantially anhydrous composition comprising at least one compound with bleaching effect, b—an aqueous composition comprising at least one oxidizing agent, and c—a composition comprising at least one cationic and/or cationizable compound.
