Description

Heptaethylene Glycol Monododecyl Ether is a high-purity, non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, known for its excellent emulsifying, wetting, and dispersing properties. This compound is critical for formulating stable emulsions and achieving superior surface activity in demanding industrial and cosmetic applications. It is essential for manufacturers in the personal care, agrochemical, textile, and industrial cleaning sectors who require a reliable, high-performance surfactant with a defined hydrophilic-lipophilic balance (HLB).

Application

• Primary emulsifier and solubilizer in cosmetic and personal care formulations, including creams, lotions, and shampoos.
• Key wetting and dispersing agent in agrochemical products such as herbicides, insecticides, and fungicides.
• Stabilizing agent for emulsion polymerization processes in the paints, coatings, and adhesives industry.
• Detergent and degreasing component in industrial and institutional (I&I) cleaning products.
• Textile processing aid for scouring, dyeing, and finishing operations to improve fiber wetting and dye penetration.
• Intermediate in the synthesis of more complex specialty surfactants and pharmaceutical excipients.
