Science

Mechanism of Action

Operating as a non-ionic surfactant, PEG-8 Caprylate effectively reduces surface tension, while its solubilizing capabilities facilitate the uniform dispersion and dissolution of diverse ingredients within a formulation. As an emollient, it functions to soften and hydrate the skin, enhancing its smooth feel and overall sensory experience. Furthermore, it acts as a solvent and plays a critical role in optimizing the delivery and efficacy of other active ingredients applied to the skin.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that PEG-8 Caprylate, along with related PEGylated alkyl glycerides, is safe for use in current cosmetic applications and concentrations, provided the final formulation is non-irritating. Notably, the previous caveat concerning its use on damaged skin was removed by the CIR Expert Panel in 2010. While the base PEG-8 is FDA approved, there is no specific maximum concentration for PEG-8 Caprylate beyond ensuring non-irritancy in the finished product.
