What is the difference between Biological and NonBiological washing powders Biological detergent contains enzymes which aid the removal of stains. They do this by reacting with the water through hydrolysis. These enzymes will often work at lower temperatures than nonbiological detergent which does not contain enzymes. In terms of the environmental impact the enzymes in biological detergent will often take longer to breakdown in the environment than using a nonbio without the enzymes. You will often have to use a higher heat setting with a nonbiological powder to get the same result however, although developments in nonbios mean they can now work at lower temperatures than previously. Some people with sensitive skin may find they are better suited to a nonbiological detergent. What are optical brighteners Most conventional detergents contain an optical brightener. This is a chemical which reflects light, making your clothes and linens look brighter than they really are. Optical brighteners make an irreversible chemical bond with the skin and exposure is more or less permanent as we are always in contact with some kind of material. Ecover will not use optical brighteners in ANY of our laundry detergents. In addition to the problems they cause to skin they do not increase the washing effect, nor the hygiene of your wash.
