Sodium C10-16 Pareth-2 Sulfate

Anionic surfactants
CAS 68585-34-2
IUPAC: Sodium ethoxylated C10-16 alcohol sulfate

Mild skin and eye irritant at concentrated form; well-tolerated at consumer-product working concentrations. No GHS classification as sensitizer, carcinogen, or reproductive toxin. Trace 1,4-dioxane from ethoxylation may trigger California Prop 65 disclosure.

Sodium C10-16 Pareth-2 Sulfate (CAS 68585-34-2) is an ethoxylated anionic surfactant — structurally similar to sodium laureth sulfate (SLES) but with a broader C10–C16 carbon chain distribution. It is commonly used in interior and multi-surface cleaners as the primary anionic surfactant, providing foam, wetting, and dirt-lifting performance. The short ethylene oxide (EO-2) chain is designed to balance foam stability with rinse-off characteristics. As an ethoxylated surfactant, it may contain trace 1,4-dioxane from the manufacturing process, which is why many Chemical Guys products that include it carry a California Prop 65 disclosure for 1,4-dioxane as an impurity.
