Abstract

The present invention relates to a composition comprising from about 0.1% to about 10% of a hydrophobic structuring agent; from about 0.1% to about 10% of a hydrophilic surfactant; from about 0.01% to about 5% of a non-crosslinked water-soluble polymer; and water, wherein the composition has a viscosity above about 15,000 cps, and has a highest G′ below about 15,000 dyne/cm² and a highest tan δ above about 0.4 in the angular frequency range of from about 0.1 rad/sec to about 1 rad/sec. The present invention also relates to a cosmetic product comprising a) a composition comprising from about 0.1% to about 10% of a hydrophobic structuring agent, from about 0.1% to about 10% of a hydrophilic surfactant; from about 0.01% to about 5% of a non-crosslinked water soluble polymer and water, and b) a container which contains the composition, wherein the composition has a viscosity above 15,000 cps, and recovers its surface flatness to have a Sa below 80 within about 24 hours when its surface is distorted to have a Sa above about 150.
