Description

Methyl (Hydroxymethyl)Octadecanoate is a high-purity fatty acid ester derivative, specifically a hydroxymethylated stearate. This compound is valued for its bifunctional nature, combining the hydrophobic character of a long alkyl chain with a reactive hydroxymethyl group, making it a versatile chemical intermediate. It is essential for manufacturers in the personal care, lubricant, and specialty polymer industries seeking to modify surface properties or introduce functional handles for further synthesis.

Application

• As a key intermediate in the synthesis of sophisticated emulsifiers and surfactants for personal care formulations.
• Used in the production of specialty esters and polymer additives for lubricants and plasticizers.
• Employed as a building block for corrosion inhibitors and textile softening agents.
• Serves as a reactive modifier in resin and coating systems to enhance flexibility and adhesion.
• Potential use in the synthesis of bio-based and sustainable chemical products.

Quality Control

Our Methyl (Hydroxymethyl)Octadecanoate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets high-purity standards suitable for industrial synthesis. Certificates of Analysis (COA) detailing purity, identity, and key physical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled 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, which can affect product quality.
