| abstract |
The invention concerns a solid composition substantially comprising between 5 and 98 parts by weight of heterocyclic compounds (I) R1-X-L1, wherein L1 stands for groups with a cyclic carbamate, a lactoneoxy or a lactam structure, X means a carbonyl, a double carbonyl or a heterocarbonyl group, and R1 designates an organic group or a second L1 group, and/or oxime esters (II), wherein L2 stands for an oxime group (a) or (b), R?2, R3 and Z4¿ designating organic groups or bridge members, L3 stands for the R1 group, a second L2 oxime group or a carbon ester group, carbon amide group, phenolate group, vinyloxy group, sulphoneamide group, imidazole group, amidolactam group, cyclic carbamate group, lactoneoxy group or lactam group, and m means 0 or 1. The composition further comprises between 2 and 95 parts by weight of inert porous carrier materials with an internal area of between 10 and 500 m2/g. The solid composition described is suitable as a stable bleach-activator component in washing, bleaching and cleaning agents. |
