Description

2,6,10,14,18,22,26,30,31-Nonahydroxy-4,8,12,16,20,24,28-Heptaoxahentriacontyl Stearate is a high-purity, multi-functional polyether ester derivative of stearic acid, designed for advanced formulation chemistry. Its unique structure, featuring a long polyether chain terminated with multiple hydroxyl groups, provides exceptional surfactant and compatibilizing properties. This specialty chemical is essential for industries requiring precise control over surface activity, emulsification, and material compatibility in complex systems.

Application

• Polymer Additive: Acts as a multifunctional processing aid, plasticizer, and compatibilizer in engineering plastics and specialty polymer blends.
• Lubricant & Grease Formulation: Serves as a high-performance synthetic base oil or additive, offering excellent thermal stability and lubricity.
• Cosmetic & Personal Care: Used as a non-ionic emulsifier and skin-conditioning agent in creams, lotions, and high-end cosmetic products.
• Industrial Surfactant: Functions as a key component in specialty detergents, wetting agents, and dispersants for challenging formulations.
• Coating & Ink Additive: Enhances flow, leveling, and substrate wetting in high-performance coatings, paints, and printing inks.
• Pharmaceutical Excipient: Potential use as a solubilizer or emulsifying agent in topical and transdermal drug delivery systems.

Quality Control

Our production of 2,6,10,14,18,22,26,30,31-Nonahydroxy-4,8,12,16,20,24,28-Heptaoxahentriacontyl Stearate adheres to a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a 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. For long-term storage, consider using an inert atmosphere (e.g., nitrogen blanket) to minimize potential oxidation.
