Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-[(1-Oxooctadecyl)Oxy]-, Ether With D-Glucitol is a high-purity, non-ionic surfactant and emulsifier derived from sorbitol and stearic acid. This compound is valued for its excellent emulsifying, stabilizing, and conditioning properties, making it a critical additive in formulations requiring mildness and stability. It is primarily sought after by manufacturers in the personal care, cosmetics, 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, dermatological preparations, and ointment bases for consistent drug delivery.
• Food-Grade Emulsification: Employed as a food additive (where compliant) for stabilizing whipped toppings, dessert creams, and other oil-in-water emulsions.
• Industrial Emulsions: Serves as an emulsifier and dispersant in textile processing, agrochemical formulations, and leather treatment products.
• Household & Institutional Products: Functions as a key ingredient in polishes, cleaning creams, and other products requiring stable emulsification of waxes and oils.

Quality Control

Our Sorbitan Monostearate is manufactured under strict quality management systems. Each batch is tested against rigorous in-house specifications, which may include parameters for identification, assay, acid value, saponification value, and heavy metals. We ensure compliance with relevant standards such as FCC (Food Chemicals Codex) and Pharmaceutical grades where applicable. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistent quality.

Storage

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