The types of enzymes used in detergents
are alkaline protease
, alkaline amylase
, alkaline cellulase
, and alkaline lipase
. They can be used in combination or separately according to the use of detergents.
1. Alkaline protease
can hydrolyze proteins into water-soluble small molecules. The bloodstain, milk stain and soy sauce stain on clothes will be enzymatically hydrolyzed under the action of alkaline protease. The structure will be relaxed and disintegrated. After a little scrubbing, the final stain will fall off from the clothes. Alkaline protease is mainly aimed at protein stain.
2. Alkaline amylase
can rapidly decompose starch into maltose, glucose and other soluble components. Therefore, amylase is used in washing formulations to remove starch-containing dirt, such as from noodles, chocolate and so on.
3. Alkaline cellulase
itself can not remove dirt from clothes. Its function is to make the structure of fibers fluffy, so that dust and dirt penetrated deep into the fibers, which can fully contact with laundry detergent, to achieve better decontamination effect. Alkaline cellulase can remove the microfibers produced by wear on cotton fibers during washing and wearing, thus restoring the original smooth state of cotton fibers. It should be noted that excessive use can also damage natural fiber fabrics such as cotton and hemp. Therefore, it is necessary to test the number of additives.
4. Alkaline lipase
can hydrolyze fat into glycerol and free fatty acids, which are easier to dissolve than the original fat. Oil stains in food and human sebum can be quickly removed by adding alkaline lipase containing fat in detergent.
