A Cleaner Vision

Anyone who’s ever lathered up knows the dilemma. The same qualities that make surfactants — the chemical compounds in soaps, shampoos and detergents that penetrate grease, dissolve stains and make those satisfying suds in the shower — so effective as cleaners can also act as irritants. When splashed in the…
