Personal cleansing compositions comprising a bacterial cellulose network and cationic polymer
United States Patent 8097574
Publication Date: Jan. 17, 2012
Assignee: The Gillette Company

Disclosed is a personal cleansing composition comprising a liquid matrix that is made up of water, 4-30% lathering surfactant and an external structurant. The structurant contains 0.05-0.5% bacterial cellulose network such as a derivatized quaternized hydroxyethyl cellulose ethers, a cellulose ether or a guar gum and 0.005-0.5% cationic polysaccharide polymer such as cationic cellulose derivatives and cationic starch derivatives and mixtures thereof. The particulate material, which is present at 0.1-30% in the composition, is suspended within the liquid matrix, and the composition has a  pH of less than about 7 or less than about 4. Methods of use and making are also provided.

These compositions provide good lathering and readily rinse off without leaving undesirable levels of slimy or filmy hand feel. The particulate materials enhance cleansing and exfoliation as well as provide conditioning benefits without damage or irritation. Formulations having pH less than about 4 are particularly preferable to enable formulation of salicylic acid formulations with the benefits of suspended dispersed phase materials.

Concentrated base for detergent products and products for personal care and hygiene comprising a combination of at least three non-ethoxylated surfactants
US Patent 8097578
Publication Date: Jan. 17, 2012
Assignee: Zschimmer & Schwarz Italiana S.p.A.

The invention relates to a concentrated base, particularly for detergent products and products for personal care and hygiene, comprising a combination of at least three surfactants selected from the group consisting of acylmethyltaurates, alkylamidopropylbetaines, alkyl amphoacetates, alkyl amphodiacetates, alkylsulphoacetates, acyl sarcosinates, acyl lactylates and acyl glutamates.
