Abstract
A disposable substantially dry cleansing article is disclosed having a lathering surfactant and a C5-C12 alkyl diol impregnated into a flexible substrate such as a non-woven cloth. The alkyl diol primarily is a process aid which may concurrently improve aesthetics and increase latherability. Hexylene glycol is the preferred diol. Best performance is achieved with an alkyl diol to total lathering surfactant weight ratio from about 1:1 to about 1:8.
