Features
GOHSENOL™ EG is a water-soluble resin which shows low skin irritation properties. It functions as a pharmaceutical excipient including a coating and granulation agent, and a cosmetic additive such as a film former and a thickener.
Also, GOHSENOL™ EG has a surfactant behavior, and functions as a polymer emulsifier for a UV absorbent, silicon, polar oil, and nonpolar oil to create a soap-free emulsifier.
