Description

Stearic Acid 1-[(Tetradecyloxy)Carbonyl]Pentadecyl Ester is a high-purity, synthetic ester derivative of stearic acid, valued for its excellent stability and hydrophobic properties. This specialized chemical serves as a versatile intermediate and functional additive, offering enhanced performance in formulations requiring specific rheological control and surface modification. It is particularly sought after by manufacturers in the cosmetics, personal care, and specialty lubricants industries for its ability to act as a premium emollient, thickener, and consistency regulator.

Application

• Cosmetic & Personal Care Formulations: Acts as a high-performance emollient, viscosity modifier, and stabilizer in creams, lotions, lipsticks, and deodorants.
• Specialty Lubricants & Greases: Functions as a synthetic ester base or an additive to enhance lubricity, thermal stability, and water resistance.
• Polymer & Plastic Additives: Used as an internal or external lubricant and processing aid in plastics manufacturing to improve flow and mold release.
• Textile & Fiber Processing: Serves as a softening agent, spin finish component, and water-repellent treatment for synthetic and natural fibers.
• Industrial Coatings & Inks: Imparts gloss control, anti-settling properties, and improved substrate wetting in various coating systems.
• Pharmaceutical Excipients: Employed as a matrix former or release-rate controller in sustained-release drug delivery systems (subject to appropriate grade and compliance).

Quality Control

Our Stearic Acid 1-[(Tetradecyloxy)Carbonyl]Pentadecyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment. We support compliance with global regulatory frameworks, including REACH, and can tailor quality standards to meet specific customer requirements for industrial, cosmetic, or technical grades.

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. Keep away from strong oxidizing agents, heat, and ignition sources.
