SOAPS are generally produced with natural food type products. Also making them more biodegradable. Like micro-splitters with a pH of 9 to 10 alkaline, with out the need for harmful chemicals and preservatives.
DETERGENTS are generally made from petroleum products with surfactants, and alcohol chemicals, most detergents are scented, with synthetic and artificial fragrances.
That's why some people have reaction's from washing detergents so use more natural soaps like the fairy brand ect without the harsh chemicals.
