About Surfactant / Cleansing Agent Ingredients
Surfactants reduce surface tension between water and oil, allowing products to cleanse, foam, and emulsify. They are essential in shampoos, cleansers, and body washes. However, surfactants vary widely in irritation potential — from harsh (sodium lauryl sulfate) to very mild (sodium lauroyl sarcosinate, decyl glucoside).
Relevance for Lauramide DEA: Repeated daily use of strong surfactants disrupts the skin barrier by removing natural lipids, increasing sensitivity to other allergens over time. If you have reactive or eczema-prone skin, choosing low-irritation surfactants and limiting wash time reduces barrier damage.
How to Identify Lauramide DEA in Products

To check whether a product contains Lauramide DEA, scan the ingredient list for its INCI name exactly as it appears above. Ingredients present at 1% or less may appear in any order after the 1% threshold.
