What is SLES?
SLES, also known as Sodium Lauryl Ether Sulfate and sodium laureth sulfate, is a widely used surfactant and detergent due to its excellent foaming and cleansing properties.
It is synthesized via the continuous SO3 sulfation of a narrow-cut fatty alcohol, ethoxylated alcohol, followed by neutralization with sodium hydroxide.
SLES is a milder version of SLS, offering a good balance of cleansing power and gentleness.

Sodium Lauryl Ether (1EO) Sulfate with Different Active Matters Content




Application of Sodium Lauryl Ether Sulfate

You’ll find SLES in tons of everyday products like shampoos, soaps, and body washes. It’s great at making foam and cleaning things well.

Beyond personal care, SLES is used in industries like printing, dyeing, petroleum, and leather processing. It can act as a lubricant, dyeing agent, cleaner, foaming agent, and degreaser.
SLES exhibits excellent performance in several key areas, including emulsification, cleansing, foaming, wetting capabilities, and high biodegradability.
Well, SLES is a type of surfactant that helps water and oil mix together by reducing surface tension. It also acts as a detergent, helping to clean stuff and get rid of dirt.
27 % SLES is a Colorless transparent liquid, and 70% SLES is a Pale straw pourable paste
The price varies according to the specifications and quantity. Generally speaking, the smaller the quantity, the higher the price; the larger the quantity, the lower the price. If you want more detailed prices, please do not hesitate to contact us!
