FIELD: cosmetic industry.
SUBSTANCE: invention relates to cosmetic industry and is a composition for bleaching of hair, consisting of their three phases, placed separately from each other and mixed immediately before use, where Phase A is a powder containing oxidizing agents – potassium and ammonium persulfates, an alkaline sodium metasilicate agent; Phase B is an oxidizing agent, which is an aqueous solution of hydrogen peroxide in an acidic medium; Phase B is oily, characterized in that a mixture of polyisobutene with the product is additionally introduced into Phase B, hydrogenated polyisobutene, ethylene/propylene/styrene copolymer, butylene/ethylene/styrene copolymer, in a ratio of 1:1, so that polyisobutene forms on the surface of the hair a hydrophobic film with high mechanical strength, which does not allow its contact with an alkaline solution that actively destroys the hair, while freely passing the gases – ammonia and oxygen, necessary for the process of discoloration of the hair.
EFFECT: invention allows to reduce the degree of damage to hair during decolorization.
