Abstract: 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.

Abstract: The invention discloses process for enhancing squeaky feel by reducing or eliminating surfactant micelles on dilution. 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, reduce surface tension and lead to 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. Micellar structure can also be reduced or eliminated by co-blending of surfactant, using co-solvent and/or using surfactants of lower Krafft point.

Abstract: An acoustic emission system for objectively measuring tactile skin attributes and methods of using same. The system includes: (A) Means for generating an acoustic emission signal from skin; (B) Means for collecting, storing and displaying said emission signal; (C) means for correlating said emission signal with an attribute of said skin; wherein said system is used as a clinical tool to evaluate efficacy of cosmetic skin care and/or cleansing products. A cosmetic product selection system is also provided which includes a cosmetic composition for reducing the appearance of undesirable skin attributes and an acoustic emission system associated with the composition. A method for assessing tactile skin attributes using an acoustic emission system, as well as of evaluating progress of the combat against the signs of undesirable skin attributes occurring over a period of time within which the composition is applied to an area of skin being monitored is provided.
