Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Ether With D-Glucitol, Heptakis(9Z)-9-Octadecenoate is a high-purity, non-ionic surfactant and emulsifier derived from sorbitol and oleic acid. This compound is valued for its excellent emulsifying, solubilizing, and stabilizing properties in complex formulations. It is primarily sought by manufacturers in the cosmetics, personal care, and pharmaceutical industries for creating stable emulsions and enhancing product texture.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and ointments, providing a smooth, non-greasy feel.
• Pharmaceutical Topicals: Used in the development of medicated creams, gels, and dermatological preparations for consistent drug delivery and stability.
• Food-Grade Emulsification: Employed as a food additive (where compliant) for stabilizing emulsions in certain edible products and food packaging coatings.
• Industrial Lubricants & Release Agents: Serves as a component in synthetic lubricants and mold release agents due to its surfactant properties.
• Agricultural Adjuvants: Functions as a wetting agent, emulsifier, or dispersant in pesticide and herbicide formulations to improve coverage and efficacy.
• Chemical Synthesis Intermediate: Utilized as a building block or modifying agent in the synthesis of more complex polymeric surfactants and specialty esters.

Quality Control

Every batch of our Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Ether With D-Glucitol, Heptakis(9Z)-9-Octadecenoate is produced under a strict quality management system. We ensure compliance with relevant standards such as USP-NF, FCC, and Kosher/Halal where applicable for specific grades. Certificates of Analysis (COA) documenting identity, purity, and key physical parameters are provided with each shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent moisture absorption. For long-term storage under an inert atmosphere such as nitrogen, please contact our technical team for specific recommendations.
