A mild functional co-surfactant. Safe.
Disodium Ethylene Dicocamide PEG-15 Disulfate (INCI same) is a mild co-surfactant derived from coconut. It stabilizes foam and softens the action of the main surfactants, which is why it is common in gels and shampoos aimed at delicate skin and frequent use. On efficacy: this is a functional cleansing and foam-texture ingredient, not a skincare active. It does not treat skin; its job is to tune the formula so it cleans without stripping. As a mildness modulator it does the job and is a sensible choice over harsher bases. It is a topical, rinse-off ingredient with no meaningful absorption. It can be used during pregnancy and breastfeeding. Tolerance is good: a mild surfactant with low irritation and allergy potential. It fits sensitive skin. Because it goes into rinse-off products, contact time is short and the drying risk is low.
