  • Patent number: 8673837
    Abstract: A shaped solid cleaning composition, especially in bar format, which utilises the detergency properties of new materials which are more efficient, relatively inexpensive and are environmentally friendly alternatives to conventional soaps or synthetics surfactants; more particularly, a shaped solid cleaning composition which comprises a specific amount of structuring agent and a specific amount of a treated particle. The precursor of the treated particle is an asymmetric 1:1 or 2:1:1 clay particle having alternating tetrahedral and octahedral sheets terminating with a tetrahedral sheet at a first external surface plane and an octahedral sheet at a second external surface plane. Either or both of said external surfaces is attached with a fatty acid or derivative thereof.

    Abstract: The present invention relates to personal cleansing bar compositions comprising:A. from about 1 parts to about 70 parts by bar weight of a mild synthetic surfactant selected from the group consisting of sodium cocoyl isethionate, sodium topped cocoyl isethionate, essentially saturated C.sub.15 -C.sub.22 alkyl sulfate, essentially saturated C.sub.15 -C.sub.22 alkyl sarcosinate, essentially saturated C.sub.15 -C.sub.22 alkyl glyceryl ether sulfonate, and mixtures thereof;B. from about 0.01 parts to about 1 parts by bar weight of a nonionic polymer;wherein the nonionic polymer is selected from the group consisting of: ##STR1## wherein x is 2; and n has an average value of from about 2,000 to about 115,000 and wherein the pH is from about 4 to about 9. These bar compositions provide enhanced clinical mildness to the skin while maintaining good lathering, increased lather lubricity and lather creaminess.

  • Patent number: 5858939
    Abstract: A method of enhancing deposition of benefit agent from bars which method comprises separately preparing an adjuvant composition comprising benefit agent and deposition polymer (e.g., cationic polymer); and base bar composition comprising a surfactant system, wherein the adjuvant composition is initially prepared by mixing components forming the adjuvant composition and water to form a uniform aqueous mixture containing benefit agents having particle size of 0.1 .mu.m to 100 .mu.m and drying said aqueous mixture to form a dried adjuvant composition. By combining adjuvant compositions separately from the base bar composition, it is possible to create a final bar having enhanced deposition of benefit agent without compromising processing or consumer attributes (e.g., foaming).

  • Patent number: 5854197
    Abstract: Cleaning compositions containing a lime-soap dispersant and a method of preparing liquid cleaning compositions containing lime-soap dispersants are disclosed. More specifically, cleaning compositions containing lime-soap dispersant polymers derived from maleic acid, maleic anhydride, or salts thereof, copolymerized with a hydrophobic monomer containing from 4 to 20 carbon atoms are disclosed. Cleaning compositions containing a lime-soap dispersant based on maleic acid/diisobutylene polymers are particulary effective in producing stable liquid cleaning compositions with good lime-soap dispersancy properties.
