SLS Free

What Is SLS?

On your skincare ingredient label, you’ll see SLS listed as Sodium Lauryl Sulfate. SLS is a surfactant that is commonly used in many personal care products such as toothpaste, shampoo, shower gel, soap, bubble bath. A surfactant is a substance which can act as a foaming agent (creates a foam for example in shampoo), or a detergent, or a wetting agent.


SLS and Cancer?

As seems to be the case with many skincare ingredients, there has been a growing fear of the link of SLS with cancer. There is so much scaremongering going on in the skincare industry from those who wish to promote natural and organic products that often rumours arise which are difficult to quash and flood the internet without much, if any, scientific backup. Such is the case with SLS. Whilst it may be touted as linked to cancer, there is, as yet, no scientific research which can prove this.


Why Should I Avoid SLS?

There are a number of good reasons to still avoid SLS such as:

  • Whilst it may not have proved to link/cause cancer, it is a known skin irritant which could be causing you itchy skin, dandruff or even dermatitis.
  • According to a study run by the University of Georgia Medicine, SLS can permeate the body’s tissues, including brain, eyes, heart and liver, for a long period of time.
  • SLS is a recognise eye irritant which may cause cataracts in adults and inhibit the proper formation of the eyes in small children.
  • SLS is a penetration enhancer meaning it can help other chemicals enter your body. SLS molecules are so small that it can cross the membranes of your cells. Once these cells have been compromised, they become vulnerable to other chemicals that may be found alongside SLS.
  • It pollutes our water. It is toxic to aquatic animals including fish and can go undetected in our drinking water.
  • The manufacturing of SLS is highly polluting. It emits sulphur compounds, air particles and even cancer-causing volatile compounds.
