Description

Glycereth-7 Trimethyl Ether is a high-purity, non-ionic polyol ether derivative, specifically the trimethyl ether of a glycerin ethoxylate. This compound matters as a versatile, hydrophilic intermediate and solvent, prized for its excellent moisture-binding properties and compatibility with a wide range of cosmetic and industrial formulations. It is primarily needed by manufacturers in the personal care, pharmaceutical, and specialty chemical industries seeking effective humectants, coupling agents, and mild solvents.

Application

• As a humectant and moisturizing agent in skin care creams, lotions, and serums.
• As a coupling agent and solvent in fragrance and essential oil formulations.
• As a hydrophilic component in surfactant and emulsifier blends for household and industrial cleaners.
• As a plasticizer and processing aid in polymer and resin applications.
• As a vehicle and solubilizer in topical pharmaceutical preparations.
• As a intermediate for the synthesis of more complex specialty esters and ethers.
• In hair care products to impart conditioning and reduce static.
