Oxidising hair composition comprising hydroxycarboxylic acids and their salts as complexing agents

摘要

Oxidizing composition for dyeing, bleaching or permanent deformation of keratinic fibers comprises an oxidizing agent and a glyconic or glycaric acid or salt thereof, other than gluconic acid and its salts. Oxidizing composition for dyeing, bleaching or permanent deformation of keratinic fibers comprises an oxidizing agent and a glyconic or glycaric acid compound of formula (I) other than gluconic acid and its salts. R(CHOH)4COOX (I) R : CH2OH or COOX; and X : H, alkali(ne earth) metal, transition metal, organic ammonium or NH4. Independent claims are also included for: (1) bleaching keratinic fibers by applying the oxidizing composition, leaving it on the fibers until the required bleaching is obtained, rinsing the fibers, and washing and optionally drying them; or permanent deformation of keratinic fibers by applying a reducing composition, putting the fibers under tension before, during or after applying the reducing composition, leaving the composition on the fibers until the required deformation is obtained, optionally rinsing the fibers, applying the oxidizing composition, leaving it on the fibers until the required fixing of deformation is obtained, rinsing, and washing and optionally drying the fibers; (2) dyeing keratinic fibers by applying a dye composition, developing the color with the oxidizing composition, and rinsing the fibers with water; (3) dyeing keratinic fibers by mixing a dye composition with the oxidizing composition, applying the mixture to the fibers, leaving the mixture on the fibers until the required color is obtained, and rinsing the fibers with water; (4) kit for dyeing keratinic fibers, comprising a dye composition and the oxidizing composition; (5) kit for bleaching keratinic fibers, comprising at least two compositions for mixing to prepare the oxidizing composition; (6) kit for permanent deformation of keratinic fibers, comprising the oxidizing composition and a reducing composition.
