POLYGLYCERYL-3 PCA.

Valuable CAS - / SKIN CONDITIONING - EMOLLIENT

POLYGLYCERYL-3 PCA is a meticulously engineered complex ester, synergistically blending the hydrophilic properties of polyglycerol-3 with the potent moisturizing capabilities of pyrrolidone carboxylic acid (PCA). It functions as a sophisticated skin conditioning agent and emollient, pivotal for enhancing epidermal hydration and reinforcing the skin's inherent barrier integrity.

Science

Mechanism of Action

This ingredient exerts its effects through a dual-action mechanism. The polyglycerol component facilitates water attraction, while the PCA moiety, a key natural moisturizing factor (NMF), actively binds and retains moisture within the stratum corneum. As an emollient, POLYGLYCERYL-3 PCA delivers exogenous lipids that strategically integrate into the intercorneocyte matrix, thereby fortifying the skin barrier, mitigating transepidermal water loss (TEWL), and enhancing overall skin resilience. Additionally, it improves skin absorption profiles and acts as an emulsion stabilizer within cosmetic formulations.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

POLYGLYCERYL-3 PCA is generally considered safe for topical application in personal care formulations and exhibits a low risk of irritation. While a specific maximum concentration has not been defined by regulatory bodies like CIR, responsible formulation practice suggests adherence to recommended usage levels to preclude potential skin sensitivity. Comprehensive toxicity data (oral, dermal, inhalation) and GHS classifications are presently undetermined, though its non-toxic and biodegradable nature is noted.
