POLYVINYL CHLORIDE.

Avoid CAS 9002-86-2 / FILM FORMING

Polyvinyl Chloride (PVC) is a synthetic polymer primarily recognized as an industrial plastic material. In cosmetic applications, it functions as a film-forming agent, creating a continuous, non-bioactive layer on the skin, hair, or nails. However, its widespread use in precision skincare is highly questionable due to significant health and environmental concerns.

Summary

Film Forming

Science

Mechanism of Action

Polyvinyl Chloride functions as a film-forming agent, establishing a continuous, non-bioactive physical barrier on the surface of the skin, hair, or nails upon application. This mechanism involves the polymer forming a coating rather than engaging in biochemical interactions with dermal structures.

Dusting Analysis

Not commonly dusted

Polyvinyl Chloride is not typically considered a 'dusted' ingredient, as its primary role is not to deliver specific biochemical benefits to the skin, but rather to serve as a structural film-former or inert material.

Stability

Polyvinyl Chloride exhibits relatively low thermal stability, degrading at elevated temperatures and releasing hydrogen chloride. It is insoluble in water and ethanol but stable under normal ambient conditions.

Conflicts

  • strong oxidizing agents
  • halogens
  • heat (causes degradation and release of hydrogen chloride)
  • certain plasticizers and additives (can leach out and cause skin reactions)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has not evaluated Polyvinyl Chloride. The European Commission has identified PVC as a source of serious health and environmental problems, with the European Chemicals Agency considering regulatory actions to limit its use and minimize microparticle release. Vinyl chloride, the monomer used to produce PVC, is a known human carcinogen. Short-term exposure to vinyl chloride can cause eye and skin irritation. Polyvinyl Chloride and its associated additives are linked to various health risks. EWG Skin Deep rates PVC as 'MODERATE' for Allergies & Immunotoxicity and 'LOW' for Cancer and Developmental and Reproductive Toxicity.

Our Assessment

Verdict

Avoid

Polyvinyl Chloride is strongly advised against for use in precision skincare due to significant documented health risks, environmental concerns, and a lack of recognized beneficial biochemical activity on the skin.
