At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing our clients with not only high-quality chemical products but also a deep understanding of their composition and synthesis. Isotridecyl Stearate (CAS 31565-37-4) is a fascinating molecule whose production and properties underscore its significance in both cosmetic and industrial sectors.

The synthesis of Isotridecyl Stearate primarily involves an esterification reaction. This process combines stearic acid, a saturated fatty acid, with isotridecyl alcohol, a branched fatty alcohol. The reaction, typically catalyzed by an acid, involves the removal of a water molecule as stearic acid and isotridecyl alcohol bond to form the ester. Modern industrial methods often employ specific catalysts and controlled conditions, such as vacuum distillation, to drive the reaction to completion and achieve high product purity. This careful synthesis is key to obtaining a compound with consistent performance characteristics.

Isotridecyl Stearate, in its purified form, is characterized as a colorless to light yellow oily liquid. Its physical and chemical properties are central to its broad utility. With a molecular weight of approximately 466.82 g/mol, it possesses a long hydrocarbon chain, contributing to its hydrophobic nature and its ability to form protective films. Its low viscosity at room temperature and a pour point below 0°C (or 7°C as reported in some sources) ensure ease of handling and excellent performance at lower temperatures, a significant advantage in many applications.

Chemically, Isotridecyl Stearate exhibits good stability, making it a reliable ingredient in complex formulations. While insoluble in water, it is soluble in various organic solvents, which is advantageous for its incorporation into non-aqueous systems or for emulsification processes. Its low acid and hydroxyl values indicate minimal residual acidity or alcohol content, further attesting to its purity.

The understanding of these properties—from its silky feel as an emollient in cosmetics to its lubricity and corrosion resistance in industrial applications—highlights why Isotridecyl Stearate is a preferred choice for manufacturers. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to sourcing and supplying Isotridecyl Stearate that meets the highest standards, ensuring that our clients can leverage its exceptional qualities for their product development and manufacturing needs. For businesses looking to purchase this versatile ester, understanding its synthesis and properties is the first step to unlocking its full potential.
