FIELD: chemistry.SUBSTANCE: invention relates to field of cosmetology and represents preparation for decolouration of keratin fibres, characterised by the fact that it contains in cosmetic carrier: i) at least one cationic derivative of 2-acylpyridinium of formula, where R is alkyl group with the number of C atoms from 1 to 4, R1 is alkyl group with the number of C atoms from 1 to 6, R2 is hydrogen atom, X is physiologically acceptable anion, ii) at least one anionic surface-active substance, selected from sulfates of alkyl ethers, corresponding to formula (II) R"-(OCH)-OSOM, where R" is linear or branched saturated or unsaturated alkyl chain with the number of C atoms from 8 to 30, n is a number larger than 2 and M is proton or physiologically acceptable cation, and iii) hydrogen peroxide or solid product of hydrogen peroxide binding to inorganic or organic compounds.EFFECT: method provides stronger decolouration of keratin fibres than application of comparable amount of hydrogen peroxide alone, which makes it possible to reduce amount of applied oxidiser and reduce damage to hair to minimum.10 cl, 3 ex |
