Thousands of these man-made synthetic chemical now make-up the environment in which we live, work and study. Those we come most into contact with are those such as shampoos which are absorbed by or irritate the skin. Accordingly we offer you products which are naturally preserved without use of synthetic preservatives or foaming agents such as Sodium lauryl sulphate (SLS). There are many derivatives of SLS that can be found in commercial preparations, including sodium laureth sulphate, sodium laureth-3 sulphate, and DEA or TEA sodium lauryl sulphate. Studies have shown a solution of just 2% SLS can increase skin thickness, cause irritation, inflammation and increase other forms of immune activity in the skin.
