Science
Mechanism of Action
As a polyene, Polypentene forms a thin, uniform film on the skin, contributing to product texture and skin feel. Its polymeric structure also increases the viscosity of non-aqueous formulations, aiding in product stability and application while acting as an emollient to enhance skin's smoothness.

Formulation
Stability
Polypentene is a high molecular weight, inert polyolefin. It exhibits complete insolubility in aqueous solutions and typical organic solvents, though it may swell in specific organic solvents. While no specific optimal pH range for its stability has been identified, general topical formulations are commonly adjusted to a pH between 4 and 6 for optimal skin health.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded Polypentene and other polyenes are safe for cosmetic use within current practices and concentrations, with usage reported up to 95% in products like lipsticks. Safety data is extrapolated from the polyene group due to chemical similarities. A human dermal sensitization study involving 100% hydrogenated polyisobutene, a related polyene, showed no irritation or sensitization. No specific SCCS opinion was found for Polypentene, but many polyenes hold FDA approval for indirect food additives and medical devices.
