Sodium Laureth Sulfate (SLS) is a synthetic surfactant made from petroleum sulfates. It is a common ingredient in cosmetic products such as shampoos, shower gels, and bath foams due to its detergent and foaming properties, as well as its cost-effectiveness.
However, Sodium Laureth Sulfate is a questionable ingredient. Several studies have suggested that SLS can be irritating to the skin and eyes. Furthermore, it can lead to skin and hair dryness and may cause contact dermatitis in some individuals. It's worth being cautious if you have sensitive or more delicate skin. SLS can also alter the skin's natural pH. However, these risks are often associated with prolonged exposure and/or high concentrations.
Since there are gentler and more environmentally-friendly alternatives available, Bleu Lavande made the decision several years ago to completely remove Sodium Laureth Sulfate from all of its products.
