General Description
Sodium Laureth Sulphate (SLES) is an anionic surfactant widely used in personal care and cleansing formulations. It is produced through the ethoxylation of lauryl alcohol, resulting in a highly effective foaming and detergency agent. Known for its excellent ability to remove oils, dirt, and impurities, SLES is valued for its balance of cleansing power, cost-effectiveness, and formulation versatility. In cosmetic chemistry, it is often used in combination with milder surfactants to fine-tune skin feel, foam quality, and overall performance.
Rebranded Ingredient Name: NANOSURF LES
Uses in the Cosmetic Industry
Sodium Laureth Sulphate is one of the most commonly used surfactants in beauty and personal care products. Key applications include:
- Shampoos & Hair Cleansers: Provides rich lather, deep cleansing, and effective removal of sebum and styling residue.
- Body Washes & Shower Gels: Creates stable, luxurious foam and a smooth cleansing experience.
- Facial Cleansers:Offers strong cleansing performance when blended with milder surfactants.
- Hand Soaps & Liquid Cleansers:Gives excellent viscosity-building and quick rinsing properties.
- Bath Foams & Bubble Products:Contributes to abundant and long-lasting foam.
- Household & Industrial Cleaners:Utilized in multi-purpose cleaning formulations (non-cosmetic category).
Hazards
Although widely used and considered safe at regulated levels, SLES has some safety considerations:
- Skin Irritation (High Concentration):Can cause drying or irritation when used undiluted or in formulations with high active surfactant content. Typically minimized through blending with gentle co-surfactants.
- Eye Irritation:May cause stinging or irritation if it comes into direct contact with the eyes.
- Contamination Concern (1,4-Dioxane):During ethoxylation, trace levels of 1,4-dioxane may be introduced; reputable suppliers remove it through purification. Cosmetic-grade SLES is regulated to meet safety limits.
- Degreasing Effect:Excessively strips natural oils if not properly balanced, potentially leading to dryness in sensitive individuals.
- Environmental Consideration:Readily biodegradable but can contribute to aquatic toxicity at high concentrations before breakdown.

Formulator’s Queries, We Answered
1) What is Nanosurf LES? What is its CAS number and INCI name?
Nanosurf LES is the commercial name for Sodium Laureth Sulfate (SLES) — an anionic ethoxylated surfactant widely used as a foaming and cleansing agent in personal-care formulations (shampoos, shower gels, liquid soaps, bubble baths, some cosmetics). The commonly referenced CAS number for SLES (industrial grades such as C12–14 ethoxylated alcohol sulfates) is 68891-38-3 and the INCI name is Sodium Laureth Sulfate.
2) What are the main benefits of using Nanosurf LES in personal-care products?
Quick list: excellent foaming and cleansing performance, economical, compatible with many co-surfactants (amphoteric/non-ionic), helps thinning/viscosity control and aids wetting and rinseability — making it a workhorse surfactant in shampoos, body washes and liquid soaps
3) Typical concentrations in finished products?
Concentration depends on product type: rinse-off products (shampoos, shower gels) commonly contain ~5–30% of a surfactant blend (SLES often used at several % up to ~10–30% depending on formulation and grade), while some supplier intermediates are sold at active strengths like 28% or 70% SLES (these are trade grades). Regulatory / ecolabel guidance also sets recommended maximums for certain product classes. Always formulate per product claims and safety data
4) Is Nanosurf LES the same as SLES / is it safe?
Chemically Nanosurf LES = Sodium Laureth Sulfate (SLES). Safety depends on concentration and use: diluted, rinse-off personal care products using properly manufactured SLES are widely used and considered safe when formulated correctly, but concentrated SLES can irritate skin and eyes and should be handled per the SDS. For workplace handling and product labelling follow the Safety Data Sheet
5) Are there known hazards or irritancy concerns?
Yes — at concentrated strengths SLES can cause skin irritation and serious eye irritation; consumer products are formulated to reduce irritation (buffering, co-surfactants, lower final concentration). Suppliers’ SDSs show hazard/precautionary statements and PPE/handling advice for concentrated grades — include links to your technical & safety datasheets on product pages
