Full Description

Sodium laureth sulfate (CAS 68891-38-3, SLES), an ethoxylated anionic sulfate surfactant also known as sodium lauryl ether sulfate. Used as a primary foaming and cleansing surfactant in shampoos, bubble baths, and household and industrial detergents.

Frequently Asked Questions

What is Sodium Lauryl Ether Sulfate (SLES) made from?

SLES is produced by ethoxylating lauryl alcohol (typically from coconut or palm kernel oil, or petrochemical sources) and then sulfating the resulting alcohol ethoxylate, followed by neutralization with sodium hydroxide. It is an anionic alkyl ether sulfate surfactant, CAS 68891-38-3. The degree of ethoxylation is commonly cited as the number after the name (e.g. SLES-2).

What is the difference between SLS and SLES?

SLES (sodium laureth/lauryl ether sulfate) is the ethoxylated form, carrying ether (EO) groups that SLS (sodium lauryl sulfate) lacks. Both are anionic foaming and cleansing surfactants; SLES is generally milder-foaming and more water-soluble in dilute systems. Confirm the exact grade and active content against the CoA for your formulation.

What is SLES used for?

SLES is a primary foaming and cleansing surfactant in shampoos, bubble baths, body washes, and household and industrial detergents. It lowers surface tension for soil and oil removal and stabilizes lather in dilute aqueous systems. RawSource supplies it as an anionic surfactant base for personal-care and cleaning formulations.

What active concentration of SLES does RawSource supply, and in what packaging?

SLES is commonly traded at around 70% active (often labeled SLES 70), and grade and active content vary by source. RawSource supplies bulk drums, totes, and IBCs; request a CoA to confirm active content, EO degree, and specifications for your supply. Contact us for available grades and current bulk pricing.

What is the HS code and CAS number for SLES?

SLES is CAS 68891-38-3. The HS classification is 3402.39 — organic surface-active agents (other than soap), anionic, other. RawSource provides the SDS and CoA with each bulk shipment for import and formulation documentation.
