Abstract
A mutated subtilisin-type protease that bears at least one mutation in its amino-acid sequence that causes the positive charge to be reduced or the negative charge to be increased in the substrate binding region of the molecule is used in cosmetic products. Such proteases show a surprisingly low skin and mucous membrane irritating potential.
