Description

Poly(oxy-1,2-ethanediyl), α-((1,2,3,4,4a,4b,5,6, 10,10a-decahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenyl)carbonyl)- ω-hydroxy-, (1R- (1alpha,4abeta,4balpha,10aalpha))-, EO 3-10 mol and EO 15-30 mol is a high-purity, non-ionic surfactant derived from a steroidal backbone and ethoxylated with a defined range of ethylene oxide (EO) units. This unique molecular structure provides excellent emulsifying, solubilizing, and surface-modifying properties, making it a critical performance additive in advanced formulations. It is essential for manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking to enhance product stability, bioavailability, and texture.

Application

• Pharmaceutical Formulations: Used as a solubilizer and emulsifier in injectable, topical, and oral drug delivery systems to improve the bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Cosmetics & Personal Care: Serves as a key ingredient in creams, lotions, and serums for its emulsifying properties and ability to create stable, elegant textures.
• Advanced Material Science: Acts as a dispersant and surface modifier in the production of nanoparticles, polymers, and specialty coatings.
• Agrochemicals: Employed in pesticide and herbicide formulations to enhance the wetting, spreading, and penetration of active ingredients.
• Industrial Emulsions: Utilized in the formulation of stable oil-in-water and water-in-oil emulsions for lubricants, textile processing, and metalworking fluids.

Quality Control

Our Poly(oxy-1,2-ethanediyl), α-((1,2,3,4,4a,4b,5,6, 10,10a-decahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenyl)carbonyl)- ω-hydroxy-, (1R- (1alpha,4abeta,4balpha,10aalpha))-, EO 3-10 mol and EO 15-30 mol CAS NO 39922-16-2 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, EO content, and performance characteristics. Comprehensive Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided and can be tailored to meet specific customer or regulatory requirements, including those for pharmaceutical applications.

Storage

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