What is Protease
Protease is a naturally occurring enzyme that breaks down protein and protein soils. There are different kinds of proteases, and they occur in animals, plants, bacteria, and fungus.
What Protease does in our products
Protease is often used as a skin conditioner to remove dry skin flakes, which is why it can be found in personal care products such as facial cleanser or makeup remover, but it is also common in laundry detergents and presoak products because it helps remove protein stains.[3,4,5,6]
How Protease made
Protease occurs throughout the natural world, but extraction from plants and animals is the primary method of obtaining protease commercially; fermentation typically produces bacterial and fungal proteases. Fermentation occurs by submerging enzyme-secreting microbes in a fermentation broth or via solid-state fermentation, which involves growing the microbes on a substrate. The microbes secrete the lipase, which is then purified and homogenized.
Why we use Protease
We use protease because it makes things clean and is a good alternative to bleach. The FDA has deemed the ingredient generally recognized as safe (GRAS) for use in food. Whole Foods has deemed the ingredient acceptable in its body care and cleaning product quality standards.[10,11,12] Several studies also show that enzymes such as protease in detergents do not result in contact skin sensitization.[13,14,15,16,17]
