Description
Sodium lauryl sulfate is a synthetic soap, or surfactant, that can be made from coconut oil, palm kernel oil or petroleum. It creates a foamy lather as it cleans, and is very effective in removing oil and dirt from clothes and surfaces. It is inexpensive and almost completely biodegradable.
SLS is a common ingredient in laundry detergents, dish soaps, shampoos and toothpaste. SLS is also in the coatings of some drugs to help them dissolve after being swallowed.
SLS is a detergent and surfuctant which essentially means that it breaks surface tension and separates molecules in order to allow better interaction between the product and your hair. This in turn creates a lather which makes products such as shampoo and toothpaste more effective cleaners. So effective and so inexpensive is Sodium Lauryl Sulfate that it’s found in a number of industrial cleaning agents such as engine degreaser and industrial strength detergents. It’s also widely used as a skin irritant when testing products used to heal skin conditions.
