摘要:
The invention provides personal care compositions comprising both alkyl phosphate surfactants and selected auxiliary agent/acid. By using specific auxiliary agent whose pKa is higher than that of the alkyl phosphate surfactants, particularly in specific ratios, it is possible to prepare milder compositions.
摘要:
The present invention relates to personal wash compositions comprising, non-silicate particles, wherein the basal layer(s) carries a net cationic charge. The use of these specific particles results in enhanced properties (e.g., enhanced foaming, hydrotroping) of the personal wash products. The invention further discloses process for decreasing viscosity and/or increasing foam comprising formulating compositions with non-silicate layer compounds as specified.
摘要:
The present invention relates to compositions, especially pastes/creams which have high level of long chain lipids or lipid mimics. These help provide “creaminess”, a desirable rheological characteristic. This is seen from defined viscosity values which define the pastes. In addition, unpredictably, when used in combination with short chain phase inducers, foam values are adequate when it would be expected the lipids would decrease foam. The composition also retains stability from physical separation.
摘要:
The invention relates to stable aqueous-aqueous emulsions defined by a dispersed phase having molecule(s) meeting special criteria and continuous phase having surfactant or surfactant system with micelles in rod-like shapes.
摘要:
The invention provides methods for obtaining dilution thickening behavior. Specifically, polydextrose induced biphasic compositions have been unexpectedly found to induce such behavior.
摘要:
The invention discloses compositions with enhanced squeaky feel, when rinsed in water, defined by a region of a surfactant-cation phase diagram comprising surfactant-cation precipitate and/or surfactant monomer, but substantially no surfactant micelle. The present invention focuses, for example, on the relationship between counter-ion (e.g., cation, preferably salt cation) and surfactant. Specifically, it has been found that enhancing the precipitation of counter-ion-surfactant complex helps reduce surfactant micellar concentration, enhance surface tension and lead to compositions with enhanced “squeaky” feel. The precipitation can in turn be promoted by enhancing surfactant counter-ion interaction, e.g., by increasing sensitivity of surfactant to counter-ion (e.g., by using long chain length hydrophobe group), and/or by preformulating additional counter-ion into the surfactant solution.
摘要:
Polysaccharides (e.g., dextran) of different molecular weights were substituted at the anomeric carbon with polyalkylene oxides of different molecular weights to give novel diblock copolymers. The copolymers inhibit bacterial aggregation. The copolymers are useful as antiplaque agents, as agents to prevent bacterial aggregation in an aqueous system or in a fermentation system.
