Abstract of Disclosure The problem of autoxidation of detergent powders containing relatively large amounts of nonionic surfactants is reduced by incorporating in the crutcher slurry a compound containing a positively charged nitrogen atom. Such compounds should be present in an amount of from ? to 6% of the resultant spray-dried powder. If desired they can be incorporated into the slurry by injection into the high pressure line to the spray-drying tower. Typical compounds containing positively charged nitrogen atoms are quaternary ammonium or organic heterocycle salts, amine oxides and betaines, although quaternary ammonium salts are preferred.
