POLY(1,4-BUTANEDIOL)-8.

Insufficient Data / NOT REPORTED

POLY(1,4-BUTANEDIOL)-8 is a polymeric compound, closely related to other poly(1,4-butanediol) copolymers. It is hypothesized to act as a film former, binder, and plasticizer within cosmetic formulations, while its monomeric unit, 1,4-Butanediol, is recognized for its humectant and solvent properties.

Science

Mechanism of Action

While specific mechanisms for POLY(1,4-BUTANEDIOL)-8 are not fully detailed, its functionality can be inferred from related polymers. Copolymers incorporating 1,4-butanediol, such as Polyurethane-8, typically form a flexible film on the skin, bind ingredients together to improve product integrity, and impart plasticity, enhancing application texture. The constituent monomer, 1,4-Butanediol, contributes humectant properties, drawing and retaining moisture to the skin, thereby improving hydration and product texture. It also functions as a solvent, aiding in the solubilization and delivery of active ingredients, which can contribute to overall product stability.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

POLY(1,4-BUTANEDIOL)-8 itself has not been reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. However, the available data for its monomer, 1,4-Butanediol, was deemed insufficient by the CIR Expert Panel to determine its safety in cosmetic applications. It is critical to note that ingested 1,4-Butanediol is classified as a Class I Health Hazard by the FDA due to its conversion to gamma-hydroxybutyrate (GHB). Furthermore, the use of non-polymerized 1,4-butanediol in domestic products has been prohibited in Australia due to potential adverse effects, indicating significant regulatory concerns regarding the monomer, which warrant extreme caution when considering its polymeric derivatives.

Verdict

Insufficient Data

While POLY(1,4-BUTANEDIOL)-8 may offer benefits as a film former, binder, plasticizer, humectant, and solvent, the lack of direct safety review for the polymer and significant health hazard classifications and prohibitions for its monomer (1,4-Butanediol) necessitate an 'insufficient-data' rating, with a strong recommendation for further comprehensive safety assessments.
