Sorbitan Tristearate, identified by CAS number 26658-19-5, is a fascinating example of a specialized surfactant with a broad range of industrial applications. As a non-ionic surfactant, it exhibits unique chemical properties that make it invaluable in formulations across food, cosmetics, pharmaceuticals, and textiles. Understanding its scientific basis is key to appreciating its versatility and effectiveness.

Chemically, Sorbitan Tristearate is a mixture of partial esters of sorbitol and its anhydrides with stearic acid. Its molecular formula, C60H114O8, and molecular weight of approximately 963.54 g/mol, indicate a complex ester structure. The compound is characterized by a waxy consistency and a light cream to tan color. With an HLB (Hydrophilic-Lipophilic Balance) value of around 2.1, it is considered highly lipophilic, meaning it has a strong affinity for oils and fats. This property makes it an excellent water-in-oil (W/O) emulsifier, capable of stabilizing mixtures where oil is the continuous phase. It is insoluble in water but readily disperses in mineral oils and vegetable oils, facilitating its incorporation into various non-aqueous systems or oil-in-water systems when paired with more hydrophilic emulsifiers.

As a premier Sorbitan Tristearate supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. ensures the consistent quality and availability of this vital industrial chemical. Its role as a dispersing agent, emulsifier, and stabilizer across sectors underscores its importance in modern manufacturing. The careful synthesis and quality control of Sorbitan Tristearate allow industries to achieve optimal product performance, from preventing fat bloom in chocolates to ensuring the smooth texture of cosmetic creams. Its position as a specialty surfactant in industry is well-deserved, driven by its unique scientific properties and versatile application range.
