Description

9-Octadecenoic Acid (Z)-, Ester With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol is a specialized ester derivative of oleic acid and a trimethylolpropane analog, functioning as a high-performance synthetic intermediate and functional additive. This compound is valued for its ability to impart flexibility, hydrophobicity, and stability to polymer matrices and surface coatings. It is essential for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product performance and durability.

Application

• Polymer Plasticizer & Modifier: Used as a co-monomer or additive to improve the flexibility, low-temperature performance, and processing characteristics of polyesters, polyurethanes, and PVC.
• Synthetic Lubricant & Grease Formulation: Serves as a base stock or viscosity modifier in high-performance synthetic lubricants and greases, offering excellent thermal and oxidative stability.
• Surface Coatings & Resins: Incorporated into alkyd resins, epoxy esters, and radiation-curable coatings to enhance adhesion, water resistance, and film flexibility.
• Personal Care & Cosmetic Ingredients: Acts as an emollient, skin-conditioning agent, and viscosity controller in creams, lotions, and makeup formulations.
• Adhesive & Sealant Formulation: Functions as a tackifier and plasticizer in pressure-sensitive adhesives and elastomeric sealants.
• Chemical Intermediate: A key building block for the synthesis of more complex surfactants, emulsifiers, and specialty esters.

Quality Control

Our 9-Octadecenoic Acid (Z)-, Ester With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications for industrial and specialty applications. Certificates of Analysis (COA) documenting purity, acid value, hydroxyl value, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
