Stabilization of papain and lysozyme for application to cosmetic products

Abstract

For cosmetic applications, papain or lysozyme was conjugated to a soluble biopolymer produced by Schizophyllum commune. Stability of the conjugated enzymes were significantly enhanced, such that more than 90% of the initial activity remained after a month storage at 45 degrees C, even in a cosmetic formulation including various oils and surfactants. Cosmetic lotion containing 1% papain conjugate was more effective in exfoliating stratum corneum of skin than the lotion containing 5% lactic acid, one of the popular exfoliating agents.
