Abstract
Abstract The invention disclosed is directed to liquid detergent-germicide compositions which include an antimicrobial active phenolic derivative in combination with hydroxyacetic acid and a detergent. The present compositions are found to have significant antimicrobial activity in water, even with low concentrations of the phenolic derivative, a low skin irritation factor, and good color stability without any substantial degree of darkening under conditions of light and heat which typically convert phenolic containing disinfectants to a dark color.
