Glyceryl Laurate

Glyceryl laurate is a monoglyceride/emulsifier with antimicrobial and surfactant-like behavior, typically used around ~0.1–3%, and it can increase disruption of the stratum corneum in reactive or eczematous skin. In patch testing and real‑world use, it is generally tolerated but has a meaningful rate of stinging/irritant dermatitis in compromised barriers, especially when layered with other cleansers, acids, or leave-on actives. For patient-safety in severe sensitivity populations, I score it as mild rather than gentle. Safety Notes: In commercial skincare and personal-care products, glyceryl laurate is commonly used at very low levels (~0.05–0.5%) as an antimicrobial/deodorizing co-ingredient or preservative booster in leave-on lotions, deodorants, and acne/blemish products, and in rinse-off cleansers to support mildness and microbial control. Higher-strength consumer products (especially natural deodorant sticks/creams, cleansing balms, and some anhydrous or high-oil systems) can use it as a functional lipid/surfactant at 3–10% for structure and performance, with 10% representing the upper end seen in OTC retail formulations rather than professional-only uses.
