The invention relates to aqueous, high active, self-preserving composition of mild surfactants which are used to create transparent liquid formulations with pH similar to skin’s pH. More specifically, the composition comprise of sodium/potassium acyl isethionate of Formula I and mono potassium acyl glutamate of Formula II with solids content of at least 45 % w/w, for personal care formulation that are ultra-mild, with skin pH and transparent.
