Science
Mechanism of Action
Ethyl Stearate functions primarily as an emollient, effectively softening and smoothing the skin's surface. It acts as a lubricant, which significantly enhances the spreadability of skincare products and contributes to a luxurious skin feel. Furthermore, it aids in reducing the perception of greasiness and can facilitate the absorption of other active ingredients. By forming a hydrophobic film, it helps fortify the skin's protective barrier, minimizing transepidermal water loss without leaving a heavy or occlusive residue.

Safety
Safety Profile
Ethyl Stearate is generally recognized as safe (GRAS) by the FDA for limited food use and is associated with low overall toxicity and biodegradability. It is deemed suitable for leave-on personal care applications, with EWG assessing it as 'LOW' risk for cancer, allergies & immunotoxicity, and developmental & reproductive toxicity. However, it's worth noting that some GHS classifications on PubChem indicate a potential to cause skin irritation (H315) at high concentrations (99.3%). The recommended usage level in fragrance concentrates is up to 8.00%.
