US Patent:

49700014, Nov 13, 1990

Filed:

May 5, 1989

Appl. No.:

7/348339

Inventors:

John J. Sheehan - Ellicott City MD

Assignee:

W. R. Grace & Co.-Conn. - New York NY

International Classification:

B01D 6302

US Classification:

210638

Abstract:

Improvement in cross-flow membrane filtration. Chitosan is admixed with an aqueous dispersion of colloids or finely divided solids to flocculate the solids. The chitosan-flocculated liquid is then filtered on a membrane by cross-flow under pressure. A layer of chitosan-containing flocculant material deposits on the membrane and provides superior flux performance as compared to certain commerical flocculants.

International Classification:

A61K 750
C11D 1700

US Classification:

510155

Abstract:

A detergent composition which is suitable for making into bars for personal washing comprises: (a) 10 to 60% wt. of a synthetic, non-soap detergent; (b) 20 to 60% wt. of water soluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40. degree. C. to 100. degree. C. ; and (c) 5 to 50% wt. of water insoluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40. degree. C. to 100. degree. C. The content of water, if any does not exceed 20% wt. of the composition and better is less than 15% wt. The materials (b) and (c) serve to give structure to the bars. The compositions can be prepared by melting together the above mentioned components at a temperature of 50-100. degree. C. , without the conventional energetic working. Desirably the molten mixture contains less than 20% wt.

Assignee:

Lever Brothers Company, division of Conopco, Inc. - New York NY

International Classification:

A61K 950

US Classification:

510152

Abstract:

A bar composition comprising about 50-80% soap, about 4 to 35% by wt. free fatty acid and less than about 4% synthetic surfactant. Addition of 1% to 10% organic salt has been found to allow use of little or no surfactant while maintaining consumer desirable properties.

International Classification:

A61K 750

US Classification:

510155

Abstract:

The present invention relates to solid detergent compositions generally comprising anionic/amphoteric/nonionic surfactant systems. Addition of specific polyol esters wherein the melting temperature and HLB are specifically defined has been found to remarkably enhance the oil/humectant structuring and releasing capabilities of a skin cleansing bar. In a second embodiment, the invention relates to a method for enhancing the bar's capability of including high levels of oil and/or humectant by carefully balancing the polyol ester's weight ratio to the oil and/or humectant. In the third embodiment, the invention relates to a method of enhancing the bar's capability of incorporating high levels of oil and/or humectant and delivering the oil and/or humectant for skin benefit by carefully balancing the polyol ester's weight ratio to the other costructurants such as PEG 8000 and fatty acid. In the third embodiment, skin mildness and especially skin moisturization are significantly enhanced by the detergent bar compositions comprising the combination of the specific polyol ester with oil and/or humectant.
