Glycerine is also added as a stabilizer and emulsifier in order to ease and stabilize the mix of fatty and watery ingredients.
Sodium laureth sulphate is a so-called anionic tenside - i.e. is an active ingredient with lathering and emulsifying effects. An emusifier enables the mix of oily and watery components, which contributes to the fact that grease, oil and dirt is easily dissolved and can be washed off.
The substance is used in many different product types - including cosmetic products such as shampoo and liquid soap as well as cleaning products and detergents.
Subtilisin is a protein splitting enzyme, which is primarily used in detergents and cleaning products. The enzyme helps remove protein-containing stains. Subtilsin is extracted from a bacteria species called Bacillus subtilis.
