Abstract

A multi-phase personal care composition is described that comprises a first visually distinct phase including a structured surfactant component and a second visually distinct phase. The structured surfactant component comprises at least one branched anionic surfactant and from 0 to 10% by weight of the first visually distinct phase, of sodium trideceth sulfate.

Claims
