Description

[2-Hydroxy-3-[(1-Oxo-9-Octadecenyl)Oxy]Propyl]Dihydrogen Citrate is a specialized organic ester compound that combines the properties of a fatty acid derivative with citric acid. This unique structure makes it valuable as a multifunctional ingredient, particularly as an emulsifier and stabilizer in complex formulations. It is primarily sought after by manufacturers in the cosmetics, personal care, and specialty chemical industries for creating stable, high-performance products.

Application

• Cosmetic & Personal Care Formulations: Acts as a non-ionic emulsifier and skin-conditioning agent in creams, lotions, and serums.
• Pharmaceutical Excipient: Used as a solubilizer and bioavailability enhancer in topical and transdermal drug delivery systems.
• Food-Grade Additives: Serves as an emulsifier and stabilizer in certain food products, where its citrate moiety can act as a sequestrant.
• Industrial Lubricants & Additives: Functions as a friction modifier and anti-wear additive in synthetic lubricant blends.
• Polymer & Plastic Additives: Employed as a plasticizer and compatibilizer to improve the flexibility and processing of specific polymer matrices.
• Agricultural Adjuvants: Used in pesticide and herbicide formulations to enhance spreading, adhesion, and penetration on plant surfaces.

Quality Control

Our production of [2-Hydroxy-3-[(1-Oxo-9-Octadecenyl)Oxy]Propyl]Dihydrogen Citrate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and moisture content are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent degradation.
