Disodium Lauriminodipropionate Tocopheryl Phosphates

Disodium Lauriminodipropionate Tocopheryl Phosphates is a water-dispersible vitamin E phosphate derivative used mainly as an antioxidant/skin-conditioning agent, typically at low concentrations in leave-on products. Available safety/patch-testing experience for tocopheryl phosphate derivatives suggests generally good tolerance, but the amphiphilic/phosphate-salt structure can behave like a mild surfactant and may sting compromised barriers (eczema, post-procedure) more than classic tocopherol. Given sensitive-skin risk and the potential for mild irritation in reactive individuals, I score it as gentle but not “very gentle.” Safety Notes: In commercial skincare, disodium lauriminodipropionate tocopheryl phosphates (a water-dispersible vitamin E phosphate antioxidant/surfactant-like derivative) is most often used at low levels (~0.05–0.5%) in leave-on serums, lotions, and sunscreens to boost antioxidant performance and formula stability. Higher-strength consumer-available products and antioxidant concentrates have been observed around ~1–3% active to maximize anti-oxidative/photoprotective claims, with higher use constrained by solubility, sensory (tack/drag), and potential irritation. It appears more commonly in leave-on products than rinse-off; rinse-off use is typically at the lower end due to short contact time.
