Sulfate Free Clear Personal Cleansing Composition Comprising Low Inorganic Salt

Patent No. EP3694483 (titled "Sulfate Free Clear Personal Cleansing Composition Comprising Low Inorganic Salt") was filed by The Procter & Gamble on Oct 10, 2018. The application was issued on Sep 7, 2022.

Patent Summary

Stable sulfate-free cleansing compositions like shampoos that are clear and transparent without the use of thickeners or stabilizers. The compositions contain anionic non-sulfate surfactants, amphoteric surfactants, cationic polymers, and low levels of inorganic salt. The anionic surfactants are typically amino acid-based. The compositions are substantially free of sulfate-containing surfactants. The low inorganic salt content prevents coacervate formation during storage. Diluting the compositions with water during shampooing causes coacervate formation between the anionic and cationic components to provide wet conditioning benefits.
