Description
Sodium Lauryl Ether Sulfate, interchangeably known as Sodium Laureth Sulfate, or SLES for short, has been a dominant surfactant used in daily household detergents, personal care products, and cosmetics. It’s a mild coconut-derived anionic surfactant with a great balance of cost and performance, dominantly used as an emulsifier, cleanser, and foaming agent in mild skin-touch products.
Thanks to its great cleaning power, mildness, and excellent compatibility with other surfactants, it can be found almost in all cleaning rinse-off products. Compared to the other rivaling primary surfactant, Linear Alkylbenzene Sulfonic Acid (LABSA), SLES is much milder, more natural, and more hard water-resistant.
YRC Chemist has been partnering with leading SLES producers, with one being our next-door neighbor, through Third-party Toll-manufacturing Agreements. We can supply top-quality SLES 70% at a competitive price, with a 10,000 MT/month capacity.
