Multiphase personal care composition comprising a structuring
The present invention relates to a personal care composition. The personal care composition comprises a surfactant phase. The surfactant phase comprises a surfactant of about 3% to about 12%, by weight of the personal care composition and a co-surfactant of about 4% or less by weight of the personal care composition. The surfactant includes sodium trideceth sulfate. The surfactant phase further comprises a structuring system. The structuring system comprises about 0.05% to about 5%, by weight of the personal care composition, of a crosslinked associative polymer and an electrolyte. The crosslinked associative polymer comprises a hydrophobic modification of less than 10% and can be hydrophobically modified with greater than a C6 alkyl. The personal care composition further comprises a benefit phase comprising a hydrophobic benefit material of about 1% to about 50%, by weight of the personal care composition.
