- Description
- Sodium Laureth Sulfate (SLES) 26 % is an anionic surfactant – an ethoxylated derivative of lauryl alcohol, which is subsequently sulfated and neutralised to the sodium salt. The base is a fatty alcohol (often from coconut/palm sources) that is ethoxylated (addition of ethylene oxide) and then undergoes sulfation ; the result is a high-foaming detergent with wide application in cosmetics and household/personal care products. The 26 % concentration means it is an aqueous solution with approximately 26 % active surfactant matter (the remainder is water and accompanying components typical for this type of raw material). SLES is known for strong foam generation and good cleansing performance, which is why it is often used as the base for shampoos, shower gels and liquid soaps; the mildness of the finished product is usually improved by combining it with amphoteric surfactants (betaines), non-ionic surfactants and humectant ingredients. Key benefits Excellent foaming – quickly produces rich foam and a pleasant “foam feel”. Strong cleansing performance – suitable for wash-off products requiring higher degreasing power. Stable and universal base – proven surfactant for shampoos, shower gels and soaps. Good compatibility – easily combined with betaines, glucosides, sarcosinates and conditioning ingredients. Practical 26 % concentration – easier dosing and dilution during manufacturing. Suitable for products such as Shampoos (classic and “performance” shampoos). Shower gels and body wash gels. Liquid soaps and hand wash gels. Cleansing gels (rinse-off) – with appropriate compositionfull description on the product page →
