Description

Sterols, Soya, Ethoxylated is a non-ionic surfactant derived from natural soybean sterols, modified with ethylene oxide to enhance its hydrophilic properties. This chemical modification is critical for creating stable emulsions and improving the solubility of active ingredients in various formulations. It serves as a key functional ingredient for formulators in the personal care, cosmetic, and pharmaceutical industries seeking natural-derived, high-performance emulsifiers and solubilizers.

Application

• Primary Emulsifier in cosmetic creams, lotions, and ointments for stable oil-in-water systems.
• Solubilizing Agent for fragrances, essential oils, and lipophilic vitamins in clear gels and aqueous solutions.
• Foam Stabilizer and Viscosity Modifier in shampoos, body washes, and other cleansing products.
• Active Carrier in topical pharmaceutical formulations to enhance skin penetration and delivery.
• Base Material for the synthesis of more complex specialty surfactants and esters.
• Industrial Applications in textile processing, agrochemicals, and lubricant additives as a bio-based surfactant component.

Quality Control

Our Sterols, Soya, Ethoxylated is produced under a strict quality management system. Each batch is tested to ensure consistent performance, including parameters such as hydroxyl value, saponification value, and degree of ethoxylation. While not a pharmacopoeial material, production can adhere to cGMP guidelines for relevant applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and physical characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage or after opening, consider storing under an inert atmosphere (e.g., nitrogen) to maintain product integrity. Keep away from strong oxidizing agents.
