Sodium Laureth Sulfate (SLES) is a surfactant derived from ethoxylated lauryl alcohol. It is commonly used in cosmetics and personal care products as a foaming agent, emulsifier, and cleanser. SLES can be contaminated with potentially toxic manufacturing impurities such as 1,4-dioxane and ethylene oxide. It can cause skin irritation, eye irritation, and respiratory problems. SLES is generally considered safe for use in products that are rinsed off, such as shampoos and body washes, but it should be avoided in leave-on products for those with sensitive skin.
1. Foaming agent: Helps create a rich, foamy lather that aids in cleansing and removing dirt and oil from the skin and hair. 2. Emulsifier: Helps stabilize and thicken solutions with ingredients of differing solubility, allowing for a more uniform texture and easier application.
Suitable for those without allergies or sensitivities to SLES. Individuals with sensitive skin, eczema, or atopic dermatitis should avoid using SLES.
1. Skin irritation: Can cause mild to moderate skin irritation, especially with prolonged exposure. 2. Eye irritation: Can cause eye irritation, redness, and tearing. 3. Respiratory problems: Can cause respiratory irritation, coughing, and shortness of breath, especially in individuals with asthma or other respiratory conditions.
1. Use in low concentrations (1% or less) in skincare products to minimize irritation. 2. Avoid contact with eyes and mucous membranes. 3. Rinse off thoroughly after use. 4. Avoid using on sensitive skin or areas with eczema or atopic dermatitis. 5. Use a moisturizer after cleansing to restore skin's moisture.

1. SLES is also used as a food additive, usually as an emulsifier or a thickener. 2. It can be found in dried egg products, some marshmallow products, and certain dry beverage bases. 3. SLES may be contaminated with ethylene oxide and 1,4-dioxane, which are potential carcinogens and can cause skin and eye irritation. 4. SLES can irritate the skin, especially in warm water and when left on the skin for an extended period. 5. SLES is generally considered safe for use in products that are rinsed off, such as shampoos and body washes, but it should be avoided in leave-on products for those with sensitive skin. 6. SLES is known to cause irritation to the skin, especially in individuals with sensitive skin or skin conditions like eczema or psoriasis. 7. It is recommended to avoid using SLES-containing products on broken or irritated skin. 8. SLES can also be irritating to the eyes and mucous membranes, so it should be avoided in products that come into contact with these areas. 9. Some studies have suggested that SLES may be linked to cancer, but more research is needed to confirm this.
