CANNABIS SEED OIL DIMER DILINOLEYL ESTERS/DIMER DILINOLEATE COPOLYMER.

Valuable / BINDING, FILM FORMING, SKIN CONDITIONING, SKIN PROTECTING, SURFACE MODIFIER

A high-performance, plant-derived polyester that serves as a sophisticated alternative to petroleum-based film formers. It combines the nourishing properties of hemp seed oil with advanced polymer science to provide a breathable, high-gloss protective barrier on the skin.

Summary

emollient film former skin conditioning viscosity controlling gloss agent

Science

Mechanism of Action

This high-molecular-weight copolymer functions by forming a flexible, substantive film on the stratum corneum. This barrier significantly reduces transepidermal water loss (TEWL) while improving the adhesion of active ingredients and pigments, resulting in enhanced hydration and product longevity.
