Abstract
Personal cleansing compositions comprising alkali metal soap and guar gum-coconut fatty acid-sodium hydroxide complex and exhibiting improved physical properties, lather properties, and mildness. The toilet bars comprise alkali metal soap and from about 0.5 to about 8% by weight guar gum, which guar gum is provided as a pre-reacted complex prepared by suspending one part by weight guar gum in from about 1 to about 12 parts by weight molten coconut fatty acid and reacting with the suspension from about 0.03 to about 0.2 part by weight sodium hydroxide per each part by weight coconut fatty acid.
Claims9
A toilet bar comprising from about 65% to about 90% by weight alkali metal soap (anhydrous basis) and from about 0.5% to about 8% by weight guar gum, said guar gum being provided in a pre-reacted guar gum complex wherein said complex is prepared by suspending 1 part by weight guar gum in from about 1 to about 12 parts by weight molten coconut fatty acid and reacting therewith from about 0.03 to about 0.2 part by weight sodium hydroxide per each part by weight said coconut fatty acid.
A toilet bar comprising from about 65% to about 90% by weight alkali metal soap, said alkali metal soap comprising a mixture of alkali metal tallow soap and alkali metal coconut soap, wherein said mixture of alkali metal soaps comprises about 4 parts by weight tallow soap per part by weight coconut soap;
- and about 4% by weight guar gum, said guar gum being provided in a pre-reacted guar gum complex wherein said complex is prepared by suspending one part by weight guar gum in about 2 parts by weight molten coconut fatty acid and reacting therewith about 0.06 part by weight sodium hydroxide per each part by weight said coconut fatty acid.
A process for preparing toilet bars comprising the steps of:
- (a) forming a pre-reacted guar gum complex by suspending one part by weight guar gum in from about 1 to about 12 parts by weight molten coconut fatty acid and reacting therewith from about 0.03 to about 0.2 part by weight sodium hydroxide per each part by weight said coconut fatty acid;
- (b) forming a mixture of said pre-reacted guar gum complex and alkali metal soap wherein said guar gum is present in said mixture at from about 0.5% to about 8% by weight of said mixture;
- (c) milling said mixture;
- (d) plodding said milled mixture;
- (e) extruding said milled and plodded mixture;
- and
- (f) stamping said extruded mixture into said toilet bars.
