Abstract

A stable multi-phase personal care composition is described. The stable multi-phase composition comprises least two visually distinct phases; wherein at least one visually distinct phase comprises a cleansing phase comprising a surfactant component. The surfactant component comprises at least one anionic surfactant selected from the group consisting of ammonium lauryl sulfate, ammonium laureth sulfate, sodium lauryl sulfate, sodium laureth sulfate, sodium cocoyl sulfate, sodium laurate, sodium cocoyl isethionate, monomethyl branched surfactants and mixtures thereof. The visually distinct phases of the stable multi-phase personal care composition form a pattern.
