The use of enzymes in detergent formulations is now mundane in developed countries, with over half of all detergents presently available containing enzymes. Dirt comes in many forms and includes proteins, starches, and lipids . in additional, clothes that have been starched must be freed of the starch. In general, enzymes detergents remove protein from clothes soiled with blood, milk, sweat, grass and many more. The detergent enzyme must be cost-effective and safe to use.
The effectiveness of detergents has been improved by the addition of specific enzymes to solubilise and remove starch and protein-based stains. Until recently, protein stains like blood were tough to exclude with regular detergent. Such stains could only be dealt with at high temperatures, and even then the stain was only partly removed. Detergent proteases offered a solution and are being continuously improved.
Proteases break down protein stains, while other enzymes such as amylases remove starch stains
