WHEREIN AT LEAST TWO OF R1, R2, R3 and R4 are acyls of organic carboxylic acids having from two to eight carbon atoms and the remainder of R1, R2, R3 and R4 are members selected from the group consisting of hydrogen, alkyl having from one to eight carbon atoms, phenyl, phenylalkyl having from seven to eight carbon atoms and acyls of organic carboxylic acids having from two to eight carbon atoms, and novel acylated glycolurils. The method of activating aqueous solutions of per-compounds utilizing an activator acylated glycoluril and solid activated compositions of solid per-compounds and an activator acylated glycoluril, said activator acylated glycoluril having the formula |
