Description

Sorbitan, Mono[(Z,Z,Z)-9,12,15-Octadecatrienoate] is a non-ionic surfactant derived from sorbitol and linolenic acid, functioning as an effective emulsifier and solubilizer. This compound is valued for its ability to stabilize oil-in-water emulsions and enhance the dispersion of lipophilic components in aqueous systems. It is primarily needed by formulators in the cosmetics, personal care, and pharmaceutical industries for creating stable creams, lotions, and topical formulations.

Application

• Cosmetic & Personal Care Formulations: Acts as a key emulsifier in creams, lotions, and sunscreens to ensure stable oil and water mixtures.
• Pharmaceutical Topicals: Used in ointments, gels, and medicated creams to improve drug solubility and skin penetration.
• Food Additive (as a surfactant): Employed as an emulsifier (E494) in certain food products, though specific grade compliance is required.
• Industrial Emulsions: Serves as a stabilizer in pesticide formulations, lubricant additives, and textile processing aids.
• Nutraceutical Delivery Systems: Facilitates the encapsulation and delivery of fat-soluble vitamins and ω-3 supplements.

Quality Control

Our Sorbitan linolenate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and hydroxyl value are available upon request. We can supply grades suitable for cosmetic, technical, and food additive applications, with compliance to relevant standards like FCC where applicable.

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). Due to its chemical property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain product integrity. Keep away from strong oxidizing agents.
