POLYVINYL METHYL ETHER.

Insufficient Data CAS 9003-09-2 / BINDING, FILM FORMING, HAIR FIXING

Polyvinyl methyl ether is a synthetic polymer primarily utilized in cosmetic formulations for its ability to form a film, bind ingredients together, and provide antistatic properties. It also contributes to product texture and adherence.

Summary

Film-forming agent Binding agent Antistatic agent Combability aid Rheology modifier Adhesion promoter

Science

Mechanism of Action

This polymer functions by creating a thin, flexible film on the skin, hair, or nails, which can improve product wear, offer protective benefits, and reduce static electricity. Additionally, it acts as an adhesion promoter and a rheology modifier, influencing the viscosity and texture of formulations.

Stability

Polyvinyl methyl ether is a thermosensitive polymer, exhibiting a low cloud point and becoming water-insoluble in aqueous solutions when heated, typically above 21-28°C. Its structure can be destabilized by additives such as higher alcohols and simple inorganic salts, leading to lower transition temperatures. The ingredient demonstrates poor chemical resistance to concentrated acids, alcohols, aromatic hydrocarbons, esters, and ketones, but maintains good resistance to dilute acids and alkalis.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

No specific safety assessment has been conducted by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS) for Polyvinyl Methyl Ether as a cosmetic ingredient. It is recognized by the FDA as an 'Indirect Additive used in Food Contact Substances'. General toxicological data indicates low acute oral toxicity (oral rat LD50 >5,000 mg/kg), and it is not identified as carcinogenic by major regulatory bodies. Dermal toxicity, however, is not consistently determined across sources.

Our Assessment

Verdict

Insufficient Data

While Polyvinyl Methyl Ether offers functional benefits as a film-former and rheology modifier, a lack of specific cosmetic safety assessments, clinical efficacy data, and determined skin compatibility metrics necessitates caution for precision skincare formulations.
