Sodium lauryl sulfate (SLS) is a surfactant that is used in many personal care and cleaning products, including soaps, shampoos, toothpaste, and floor cleaners. It is a cleansing agent that is known for being very effective at its job, producing copious, creamy, and luxurious foam. However, it can also potentially irritate the skin.
Positive aspects of SLS:
- It is a very effective cleansing agent.
- It can produce copious, creamy, and luxurious foam.
- It is an emulsifier and can work as a penetration enhancer for active materials.
Negative aspects of SLS:
- It can potentially irritate the skin.
- It can be found in household cleaners and can leave residues on food contact surfaces.
- It has been linked to urban myths about cancer and skin irritation, but research suggests that concentrations of one percent or less are safe on the skin.
Ingredients or materials:
- SLS is an anionic surfactant that is naturally derived from coconut and/or palm kernel oil.
- It usually consists of a mixture of sodium alkyl sulfates, mainly the lauryl.
- It can be found in concentrations of up to 30% in personal care products.
Overall, SLS is a common ingredient in many personal care and cleaning products, and while it can potentially irritate the skin, research suggests that it is safe to use in concentrations of one percent or less.
