• Factsheet

General Description:
Sodium Laureth Sulphate (SLES) is a widely used synthetic surfactant and detergent. It is derived from ethoxylated lauryl alcohol and is often produced from palm kernel oil or coconut oil. SLES appears as a white to yellowish paste or clear liquid and is known for its ability to create a rich lather, making it a popular ingredient in many personal care products.

Uses in the Cosmetic Industry:

• Surfactant and Foaming Agent: SLES is primarily used as a surfactant and foaming agent in shampoos, body washes, facial cleansers, and hand soaps. It helps to remove dirt, oil, and impurities by reducing the surface tension of water, allowing it to spread and penetrate more easily.
• Cleansing Agent: It is an effective cleansing agent, providing thorough cleaning of the skin and hair. It is commonly found in household cleaning products as well as personal care products.
• Emulsifying Agent: SLES acts as an emulsifier in cosmetic formulations, helping to blend oil and water-based ingredients to create stable emulsions. This is important in products such as lotions and creams.
• Solubilizing Agent: It helps to solubilize oils and other lipophilic ingredients in water-based formulations, ensuring even distribution throughout the product.
• Thickening Agent: SLES can contribute to the thickness and viscosity of liquid products, enhancing their texture and user experience.

Hazards and Safety Concerns:
While Sodium Laureth Sulphate is effective and widely used, there are some potential hazards and safety concerns associated with its use:

• Skin Irritation: SLES can cause skin irritation, especially with prolonged or repeated use. Individuals with sensitive skin or conditions such as eczema may experience redness, dryness, and itching. It is important to use formulations with appropriate concentrations to minimize irritation.
• Eye Irritation: Contact with the eyes can cause irritation and discomfort. Care should be taken to avoid eye contact when using products containing SLES.
• Potential Contaminants: The manufacturing process of SLES involves ethoxylation, which can lead to the presence of potentially harmful byproducts such as 1,4-dioxane, a suspected carcinogen. Reputable manufacturers take steps to minimize these impurities, but trace amounts can sometimes be present.
• Environmental Impact: SLES is biodegradable, but its widespread use and disposal can contribute to environmental pollution, particularly in aquatic ecosystems. Efforts to reduce the environmental footprint include using sustainably sourced raw materials and proper waste management practices.
