Protease ST-4L (cleaning)

An Enzyme Supplies alkaline liquid protease for laundry detergents

Description

Protease ST-4L is an alkaline liquid protease for use in biological detergent products (both laundry and dishwashing). The product acts by hydrolyzing insoluble protein soiling into soluble peptides and amino acids which can then be readily removed from clothing fabric or dishes. Protease ST-4L is particularly effective at removing common household soiling such as blood, grass, milk, gravy and blood.
Protease ST-4L is a particularly high strength enzyme derived from a genetically modified strain of Bacillus subtilis, and works in conjunction with the other laundry and dishwashing chemicals to remove most protein based stains under a broad range of conditions.
