![]() ![]() ![]() Many complex, stubborn stains come from a range of modern food products such as chocolate ice cream, baby food, desserts, dressings, and sauces. Research is currently being carried out with a view to extending the types of enzymes used in detergents. The most widely used detergent enzymes are hydrolases, which remove protein, lipid, and polysaccharide soils. Starch and fat stains are relatively easy to remove in hot water, but the additional cleaning power provided by enzymes is required in cooler water. The trend toward lower wash temperatures, in particular in Europe, has also increased the need for additional and more efficient enzymes. One of the driving forces behind the development of new enzymes and the modification of existing ones for detergents is to make enzymes more tolerant of other ingredients, such as builders, surfactants, and bleaching chemicals, as well as of alkaline. Many detergent brands are based on a blend of two or more enzymes - sometimes as much as eight different enzymes. A further desirable effect of cellulases is to impart greater softness and improved color brightness of worn cotton surfaces. In this way, particulate soils attached to microfibrils are removed. Cellulases clean indirectly by gently hydrolyzing certain glycosidic bonds in cotton fibers. Enzymes in (heavy-duty) detergents degrade and thereby help solubilize substrate soils attached to fabrics or hard surfaces (e.g., dishes). Anionic surfactants and polymers further increase the repulsive force between the original soil, the enzymatically degraded soil, and the fabric, which prevents the soil from redepositing on the fabric.īuilders act to chelate, precipitate calcium and magnesium components, to provide alkalinity and buffering capacity, and to inhibit corrosion. Surfactants of various kinds help wash liquor to wet fabrics, and they assist in removing various stains by lowering the surface tension at the interface between the wash liquor and the fabric. Stains are removed by mechanical action assisted by enzymes, surfactants, polymers, and builders.
