Description

Sorbitan, Mono(12-Hydroxy-9-Octadecenoate), [R-(Z)]- is a specialized sorbitan ester derived from ricinoleic acid, a naturally occurring fatty acid. This compound serves as a versatile non-ionic surfactant and emulsifier, valued for its ability to stabilize formulations and improve compatibility between oil and water phases. It is particularly sought after by manufacturers in the cosmetics, personal care, and pharmaceutical industries for creating stable emulsions, creams, and lotions with a smooth texture.

Application

• Primary emulsifier and stabilizer in cosmetic creams, lotions, and ointments.
• Key ingredient in personal care products such as sunscreens, makeup, and hair conditioners.
• Used in pharmaceutical topical formulations for controlled drug delivery.
• Acts as a solubilizer and dispersing agent in various industrial and specialty chemical preparations.
• Functions as a co-emulsifier alongside other surfactants to enhance emulsion stability and texture.
• Potential use in food-grade applications as an emulsifier, subject to specific purity grades and regulatory approvals.

Quality Control

Our Sorbitan monoricinoleate is produced under a strict quality management system. Each batch undergoes comprehensive 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, hydroxyl value, and moisture content are available upon request. We can support compliance with relevant standards for cosmetic (ISO 22716) and pharmaceutical (cGMP) applications.

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). This product is easily oxidized; for long-term storage, consider maintaining an inert atmosphere (e.g., under nitrogen) in the headspace of the container. Keep away from strong oxidizing agents.
