FIELD: chemistry.
SUBSTANCE: invention relates to a bleaching system for household textile items containing at least one bleaching agent, where the bleaching system is selected from peroxybenzoic acid, peroxy-6-naphthoic acid, peroxylauric acid, peroxystearic acid, phthalimido peroxycaproic acid, 6-phthalimido peroxyhexanoic acid, nonylimido peroxyamber acid, nonylimido peroxyadipic acid, 1,12-diperoxydodecanoic acid, 1,9-diperoxyazelaic acid, diperoxyisophthalic acid and 2-decyldiperoxybutane-1,4-diacid and coated by a shell in form of a layer of a polymer with urethane and urea groups, where a prepolymer with terminal NCO groups is obtained from macrools, ionic or potentially ionic polyols and polyisocyanates used in excess, said prepolymer being subjected to reaction with compounds which contain at least two amine groups which are reactive towards isocyanate with ratio of NCO groups to NH groups less than or equal to 1:1, after which said polymer is obtained via neutralisation.
EFFECT: obtaining a novel bleaching system.
