COSCAP G7-MC is the trimethyl ether of glycereth -7. This transparent, light yellow liquid ester produces a slightly dry, silky emollience on the skin. Two key properties are its water-solubility and its dispersibility in castor oil, allowing the introduction of water/water soluble actives into anhydrous systems.

COSCAP PME-3 is a propoxylated ether and is hydrolytically stable over a wide pH range enabling the formulator to incorporate it into salicylic acid and AHA formulations as well as into high-pH systems.
