Abstract
The autoxidation of aqueous detergent slurries containing major quantities of nonionic surfactant during spray-drying is inhibited by the use of a charge-transfer agent. The charge-transfer agent may be a charge-transfer acceptor or a charge-transfer donor or a precursor of either of these. The agent may be present in an amount of from 0.05 to 2% by weight and the nonionic surfactant in an amount of 3% or more by weight based on the weight of the fully formulated detergent powder. The preferred charge-transfer agent is potassium iodide.
