Microwash contains no solvents, no perfumes and no soap and is pH controlled to match that of the skin, so the skin will not dry out like it can with some hand cleaners. The surfactants contained in this hand soap are highly biodegradable and have been selected for their low skin irritancy. A gentle emollient moisturises the skin. It can quite safely be used as an all-over body wash, including for the washing of hair. Unlike some hand cleaners, Microwash Food Grade Hand Soap does not lose its efficiency in hard water, sea water or bore water.
