METHOXY PEG-23 METHACRYLATE.

Questionable / NOT REPORTED

METHOXY PEG-23 METHACRYLATE is a synthetic methacrylate monomer, primarily serving as a versatile building block for creating polymers and copolymers. These resulting polymeric structures contribute to the textural, stability, and sensory properties of cosmetic formulations.

Science

Mechanism of Action

As a polyethylene glycol (PEG) derivative, METHOXY PEG-23 METHACRYLATE functions by undergoing polymerization reactions, often initiated by radical agents or UV light, to form larger polymeric structures. These polymers can act as film-formers to create a protective layer, or as viscosity-increasing agents to enhance product texture and stability. The PEG component generally supports the solubility of various compounds in aqueous solutions, contributing to formula elegance, though direct skin benefits from the monomer itself are not indicated.

Dusting Analysis

Not commonly dusted

This ingredient is a monomer intended for polymerization into larger structures within a formulation, not typically used as an active ingredient with a recommended direct application percentage. Safety concerns are primarily associated with direct skin contact with the monomer form.

Stability

Methoxy polyethylene glycol-Methacrylate should be stored dried at -20℃ and away from light to prevent premature polymerization. Inhibitors, such as 4-Methoxyphenol (MeHQ) or BHT, are typically added at approximately 200 ppm to maintain stability. Its methacrylate groups are highly reactive in vinyl photopolymerization or co-polymerization processes.

Conflicts

  • strong polymerizing agents
  • oxidizing agents
  • conditions that initiate radical polymerization (e.g., uncontrolled UV light, heat)

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk High

The Cosmetic Ingredient Review (CIR) Expert Panel and the Scientific Committee on Consumer Safety (SCCS) have concluded that methacrylate ester monomers, including this ingredient, are safe only when skin contact is strictly avoided due to their significant sensitizing potential. Products containing these should explicitly direct users to prevent dermal exposure. Related compounds like methyl methacrylate are known irritants to the skin, eyes, and mucous membranes, capable of causing allergic responses. For copolymers containing this ingredient, meticulous formulation is essential to prevent potential toxic impurities. While general PEG ethers are deemed safe when non-irritating, the specific risks of the methacrylate monomer must be carefully managed.

Verdict

Questionable

While valuable as a monomer for creating functional cosmetic polymers that enhance texture and stability, the ingredient itself presents a high risk of sensitization and irritation upon direct skin contact, making its use questionable unless strictly controlled within polymerized structures to ensure no free monomer remains.
