3-HYDROXYBUTYRATE/3-HYDROXYHEXANOATE COPOLYMER.

Valuable / ABRASIVE

A sustainable bio-based polymer derived from microbial fermentation that serves as an eco-friendly alternative to synthetic microplastic beads in cosmetic formulations. These spherical microspheres deliver superior sensory enhancement, mattification, and gentle exfoliation while remaining completely biodegradable.

Abrasive Absorbent Viscosity Controlling Sensory Enhancer Mattifying Agent

Science

Functions as microscopic ball-bearing spheres that reduce friction during application while improving product spreadability. The porous structure effectively scatters light to create optical blurring effects and absorbs excess sebum for mattification, while providing gentle physical exfoliation when used in cleansing products.
