Description

3-Octadecene-1,2-Diol is a long-chain aliphatic diol characterized by an unsaturated octadecene backbone. This compound is valued for its bifunctional nature, serving as a versatile intermediate and building block in specialty chemical synthesis. It is primarily sought after by manufacturers in the personal care, polymer, and lubricant industries for its surfactant and rheology-modifying properties.

Application

• As a key intermediate in the synthesis of non-ionic surfactants and emulsifiers for cosmetic and personal care formulations.
• Utilized as a monomer or co-monomer in the production of specialty polyesters and polyurethanes, imparting flexibility and hydrophobicity.
• Acts as a precursor for lubricant additives and corrosion inhibitors in industrial lubricant packages.
• Employed in the manufacture of textile auxiliaries and fiber finishing agents.
• Serves as a building block for plasticizers and stabilizers in polymer processing.
• Used in research and development for creating novel lipid-based compounds and vesicles.

Quality Control

Our 3-Octadecene-1,2-Diol is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise customer specifications and consistent lot-to-lot performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and potential degradation.
