TRIMETHYL PENTANYL DIISOBUTYRATE.

Optional CAS 6846-50-0 / PLASTICISER

Trimethyl Pentanyl Diisobutyrate is a functional ingredient primarily employed to enhance the texture and application of cosmetic formulations. It acts as a plasticizer, increasing product flexibility, and a film-forming agent, contributing to a smooth, durable finish.

Summary

Plasticizer Film-forming agent Viscosity enhancing agent

Science

Mechanism of Action

This ingredient operates primarily as a plasticizer, imparting greater flexibility and fluidity to cosmetic substances, which results in more spreadable products and a consistent, smooth texture. Concurrently, it functions as a film-forming agent, particularly effective in nail applications, where it creates a resilient, long-lasting coating that resists chipping. Its presence also contributes to optimized formulation viscosity, promoting effortless application and uniform coverage.

Sensitization risk Moderate

While the Cosmetic Ingredient Review (CIR) has classified Trimethyl Pentanyl Diisobutyrate as safe for cosmetic use and the FDA permits its use as an indirect food additive, caution is advised. Some individuals may experience mild skin irritation or allergic reactions, thus recommending patch testing. Furthermore, INCI Beauty lists it as a suspected endocrine disruptor, and Environment Canada classifies it as a suspected environmental toxin, warranting careful consideration in product development.
