The process employs an activating agent of formula: <IMAGE> in which R1, R2 and R3 are optionally substituted alkyl or aryl groups, R4 is an alkyl or aryl group substituted with at least one ester group, m, r and n are integers and Ar<-> is an anion such that m x r = n. The activating agent may be incorporated in a powder for washing textiles or for scouring hard surfaces. |
