Abstract:
A method of manufacturing a non-soap cleansing bar, having good lathering characteristics, a smooth feel and a resistance to cracking on drying, comprising:(a) a first surfactant component comprising a quaternary surfactant of the formula ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each hydrogen or alkyl, andwherein the total number of carbon atoms therein is in excess of 10, andwherein X is a counter anion, said first surfactant component being present in an amount of 0.1.5.0% by weight,(b) a second surfactant component comprising at least one anionic surfactant present in an amount of about 15-45% by weight,(c) a filler component comprising at least one filler selected from the group consisting of non-starch carbohydrates, starches and starch hydrozylates, said filler component being present in amounts of 45-80% by weight,(d) about 0-20% by weight waxy binder having a melting point between 40.degree.-70.degree. C., and(e) about 5-20% by weight water, wherein said non-soap cleansing bar may be manufactured by plodding, comprising melting said waxy component, mixing said remaining components of said non-soap cleansing bar with said melted waxy component, preparing particles of said mixture, and plodding said particles by extrusion.
