Ethoxylated derivative of SLS with larger molecular weight, reducing but not eliminating irritation potential. Less protein-denaturing than SLS but still capable of stratum corneum lipid disruption at high concentrations.
The research
Sodium Laureth Sulfate is a surfactant irritant backed by a moderate body of supporting evidence (evidence tier 2 of 4). We track 2 studies for it, 1 reporting a positive effect.
Irritant patch-test profile comparing detergents: sodium laureth sulfate (SLES) was significantly less irritant than sodium lauryl sulfate but more irritant than alkyl polyglucoside, indicating that ethoxylation reduces but does not eliminate SLES irritation potential.
In a controlled washing assay (3 lab washes plus 1 week of home use) on the volar forearm and dorsal hand, squamometry discriminated the subclinical, non-erythematous skin-surface irritation caused by SLES versus SLS, detecting surfactant-induced stratum corneum alterations after as few as three washes.
