Abstract

This invention relates to fabric and home care products comprising one or more cold water proteases and processes for making and using such products. Such compositions provide improved cleaning and freshness. Such cold water proteases may be derived from parent enzymes, including BPN′ subtilisin and subtilisin derived from Bacillus lentus, by substitution, insertion and/or deletion of one or more of the parent enzymes' amino acids.
