COMPOSITIONS HAVING ENHANCED DEPOSITION OF SURFACTANT-SOLUBLE ANTI-DANDRUFF AGENTS

摘要

The present invention is directed to a hair care composition comprising from about 8% to about 25% of one or more surfactants from about 0.01% to 10% of one or more surfactant-soluble agent; wherein the composition has a fractional soluble agent concentration (a) of 0.5-1.0 wherein ‘a’ is defined as; $$ a=\frac{C}{\&\#x2211;K_s^iC_s^i}$$ ;where C is the surfactant-soluble agent concentration, C_sⁱ are the surfactant concentrations and K_sⁱ is the solubilization capacity of each type of surfactant (e.g. in units of ppm octopirox/weight percent of surfactant) wherein K_sⁱ can be measured easily for any surfactant and surfactant-soluble agent combination.
