Description

Poly(Oxy-1,2-Ethanediyl), α-Benzoyl-ω-Hydroxy- (Eo 3-10 Mol And 15-45 Mol) is a non-ionic surfactant and emulsifier belonging to the class of polyethylene glycol (PEG) esters of benzoic acid, defined by its specific ethylene oxide (EO) chain lengths. This compound is valued for its ability to modify surface tension and act as a solubilizer and stabilizer in complex formulations. It is a critical raw material for manufacturers in the cosmetics, personal care, pharmaceutical, and specialty chemical industries seeking reliable performance and consistent quality.

Application

• Cosmetic & Personal Care Formulations: Acts as a solubilizer for fragrances and essential oils, an emulsifier in creams and lotions, and a stabilizer in clear gels.
• Pharmaceutical Excipient: Used as a non-ionic surfactant in topical drug delivery systems and as an emulsifying agent in ointments and creams.
• Industrial Emulsification: Serves as an emulsifier and stabilizer in the production of polymer emulsions, agrochemicals, and textile processing aids.
• Chemical Intermediate: Utilized in the synthesis of more complex surfactants and specialty esters for targeted performance properties.
• Household & I&I Cleaning: Functions as a wetting agent and detergent component in specialty cleaning formulations.

Quality Control

Our production of Poly(Oxy-1,2-Ethanediyl), α-Benzoyl-ω-Hydroxy- adheres to stringent quality management protocols. Each batch is tested to ensure consistent performance characteristics such as hydroxyl value, saponification value, and ethylene oxide content. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
