Sodium Laureth Sulfate
What is Sodium Laureth Sulfate?
Sodium Laureth Sulfate (SLES) is a common surfactant used in many personal care products. It is made from ethoxylated lauryl alcohol derived from either coconut oil or petroleum, then treated with sulfuric acid and neutralized with sodium carbonate.
SLES is primarily used in shampoos and soaps for its ability to create a foamy lather, which helps to clean and remove oils from the hair and skin. However, it has been a subject of concern due to reports of skin irritation in some people, and environmental impact due to its manufacture and degradation.
For consumers, it's important to be aware that while SLES is effective at cleansing, it may not be suitable for those with sensitive skin or those seeking eco-friendly products.
Commonly found in: Shampoos, Body Washes, Face Cleansers, Toothpastes, Liquid Soaps
What to watch
- Some people experience skin irritation and dryness from SLES.
- Environmental concerns due to its manufacturing process.
Benefits
- Effective as a cleansing and foaming agent in personal care products.
The FDA does not specifically regulate SLES, but it is considered safe for use in cosmetics as per general safety standards.
Studies recognize SLES as an effective surfactant but highlight potential skin irritation issues and environmental concerns.
SLES is typically considered vegan as it is not derived from animal sources.

Scout's take
Ethoxylated sulfate cleanser in a conditioner -- unusual and unnecessary. Carries 1,4-dioxane (IARC Group 2B probable human carcinogen) contamination risk.
