Sodium Dilauramidoglutamide Lysine

Sodium Dilauramidoglutamide Lysine is an amino-acid–derived amphiphilic surfactant/emulsifier used at low percentages in cleansers and barrier-support formulas, generally designed to be milder than traditional anionic detergents. While it is typically well-tolerated in patch testing and sensitive-skin use, any surfactant can provoke stinging or dryness in compromised eczema skin—especially when combined with other cleansing agents or frequent washing—so it is best categorized as very gentle rather than inert. Safety Notes: Sodium Dilauramidoglutamide Lysine is a mild amino-acid–derived anionic surfactant/foam booster used mainly in rinse-off cleansers, shampoos, and body washes; in commercial formulas it is often present at low levels (~0.05–0.5%) as a secondary surfactant or sensorial/foam modifier. Higher-strength consumer-available rinse-off products (including sulfate-free and high-foam cleansing bases) can use it as a primary or co-primary surfactant system component around ~1–5% to build viscosity and foam while maintaining mildness; it is rarely used at meaningful levels in leave-on products.
