Sodium Laureth Sulfate (sodium lauryl ether sulfate/SLeS) is an anionic surfactant made from coconuts. It should not be confused with Sodium Lauryl Sulfate (SLS)—SLeS is much milder. Clear, viscous liquid or a smooth, thick paste—it is available at different concentrations and more concentrated versions are thicker.

First, sodium lauryl sulfate is the sodium salt of lauryl sulfate. SLS has the following formula: C₁₂H₂₅NaO₄S. Sodium laureth sulfate is the sodium salt of a sulfonate ester. SLES has the following formula: C₁₄H₂₉NaO₅S. (There's also another chemical with a similar name, sodium laurate, which differs from both SLS and SLES.
