ACRYLOYL DIMETHYL TAURATE/MELAMINE/PEG-6 METHACRYLATE/PHLOROGLUCINOL CROSSPOLYMER.

Questionable / BINDING

This intricate crosslinked polymer functions primarily as a versatile formulation aid, enhancing product texture and stability. It acts as an effective binder, dispersing agent, and emulsion stabilizer, while also increasing aqueous viscosity. Its film-forming and oil-absorbing properties suggest potential benefits for a refined skin feel.

Science

Mechanism of Action

ACRYLOYL DIMETHYL TAURATE/MELAMINE/PEG-6 METHACRYLATE/PHLOROGLUCINOL CROSSPOLYMER operates as a multifunctional polymer within cosmetic formulations. Its complex crosslinked structure enables it to perform as a binder and stabilize emulsions through electrostatic interactions, which effectively entrap oil droplets and impart a high yield value. Additionally, it significantly increases aqueous viscosity and can contribute to a smooth skin feel by forming a subtle film and absorbing excess sebum, potentially mitigating concerns such as unwanted shine and pore congestion.

Stability

Polyethylene glycols (PEGs), integral to this crosspolymer, are generally water-soluble and demonstrate good skin tolerance. Related acryloyldimethyltaurate polymers are recognized for their robust stability in low-pH formulations and high resilience when exposed to UV light.

Conflicts

  • Not permitted in organic or natural certified cosmetic formulations due to the presence of ethoxylated substances, specifically PEG-6 methacrylate, which involve ethylene oxide – a compound with known carcinogenic concerns – in their production process.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has assessed the broader class of acryloyldimethyltaurate polymers, concluding they are safe for cosmetic use within current practices and concentrations. These polymers, characterized by their large molecular weights (typically >1,000 to >1,000,000 g/mol), are not expected to be absorbed through the skin. A primary safety concern focuses on minimizing residual monomers, such as acrylamide, vinyl formamide, and methacrylamidolauric acid, with recommendations for manufacturers to adhere to current good manufacturing practices (cGMPs). However, one source (Sinaí Estética) expresses significant doubt, rating this specific ingredient as 'Muy Dudoso' (Very Doubtful), raising concerns that it may weaken skin protection and highlighting the use of ethoxylated substances (like PEG-6) which are excluded from organic certifications due to ethylene oxide. While no specific SCCS or FDA approval for this exact ingredient was found, related acryloyldimethyltaurate polymers are regulated in Europe concerning residual acrylamide content, with limits of 0.1 mg/kg in leave-on and 0.5 mg/kg in other cosmetic products.

Verdict

Questionable

While the broader class of acryloyldimethyltaurate polymers is generally considered safe as formulation aids, specific clinical efficacy and comprehensive safety data for this complex crosspolymer are limited, with notable concerns raised regarding its ethoxylated components and potential impurities.
