Biological Washing Powder: Do you call this Powder Detergent in the USA? The
biological bit I think means it is composed with
enzymes do dissolve /breakdown dirt and stains in the process. As opposed to washing out the dirt particles from say fabric. I think it is worth noting that if the clothes say, are not rinsed thoroughly to remove the
detergents / enzyme residue some people can have an allergy or irritation especially if intimate garments; less likely with non-
biological detergent which is more gentle. Is this helpful?
