PEG-4/PPG-1 PENTAERYTHRITYL TETRAACRYLATE.

Avoid CAS 144086-02-2 / NAIL CONDITIONING

PEG-4/PPG-1 PENTAERYTHRITYL TETRAACRYLATE is a synthetic polymer, specifically a tetrafunctional acrylate ester. While primarily identified for its utility in nail conditioning formulations, its comprehensive safety profile and mechanism of action for direct skin application remain largely uncharacterized, raising significant concerns.

Stability

Similar to its related compound, Pentaerythritol tetraacrylate (PETA), this ingredient exhibits light sensitivity. Formulations incorporating it typically require the addition of polymerization inhibitors, such as monomethyl ether hydroquinone (MEHQ), to prevent premature polymerization and ensure product stability.

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed PEG-4/PPG-1 PENTAERYTHRITYL TETRAACRYLATE. While some related PEG compounds have been assessed as safe, a closely related tetrafunctional acrylate ester, Pentaerythritol tetraacrylate (PETA), is classified by OSHA as a hazardous substance. PETA is known to cause irritation to the eyes, respiratory system, and skin, and carries a significant risk of skin sensitization. Furthermore, multifunctional acrylates in general are associated with inducing skin disorders and inflammation.

Verdict

Avoid

Given the absence of a specific safety assessment for this ingredient in skincare applications and the known irritation and sensitization potential of related acrylate esters, its use is strongly discouraged for topical formulations.
