METHOD FOR PREPARING STABILIZED ALKYL GLYCOSIDES

摘要

Glycoside products having a propensity to discolor and/or to exhibit haze under aqueous alkaline or neutral pH conditions can be stabilized to substantially reduce the extent of discoloration and to essentially eliminate any haze which might also be present by adjusting the pH of a hydrogen peroxide-free aqueous solution of the alkyl glycoside product to about 7 prior to treatment with a metal borohydride material which at the end of the reaction period is consumed resulting in a stabilized alkyl polyglycoside product which does not exhibit a haze in an aqueous solution at a pH of about 7.
