Sodium Lauryl Sulfate vs Sodium Laureth Sulfate

Hey Curly Naturals,

If you are like me and consistently scanning the Natural hair isle for products and scanning the ingredient list at the back of the bottle, you might have asked yourself the same question. What is the difference between Sodium Laurel/Lauryl  Sulfate and Sodium Laureth Sulfate. I also get confused by the usage of Sulfate and Sulphate.

I will break it down for you.

According to wikidiff.com

Sulfate and Sulphate are alternative forms of one another. Basically they can be used interchangeably.

Sulfate = mainly US

Sulphate = mainly UK

  • Both are Surfectants added to products to make them foam.
  • Sodium Laureth Sulphate is to be be more gentler on hair and skin. (although the list below has classified it otherwise)
  • Sodium Lauryl Sulphate has been proven to be a skin irritant and disturbs the skins natural balance and also said to cause cancer.

I found this image below on the from botoxhair.net and it gives pretty good breakdown between gentle sulphates/sulfates and harsher ones

So to bring it all together:

Sodium Laureth Sulphate is a gentler sulphate and the spelling of sulphate/sulfate are alternatives of one another.
