SLS Free


Sodium Lauryl Sulfate (commonly known as SLS) is a widely used chemical found in a huge range of mainstream personal products from shampoos to toothpaste, and also in cleaning products.

SLS is a detergent which breaks surface tension and separates molecules in order to allow better interaction between the product and your skin or hair. However, it’s also widely used as a skin irritant when testing products and a 1983 report published by The American College of Toxicology (ACT) found that even relatively low concentrations of less than half a percent can result in skin irritation, and that higher concentrations were responsible for severe irritation and even corrosion of the skin. Cleaning products can have levels of SLS as high as 10-20% and in many cases over 30%, meaning that SLS remains a concern for many people.
