Understanding the precise chemical properties of specialized compounds is fundamental to their successful application in industry. Octylheptamethyltrisiloxane, cataloged under CAS number 17955-88-3, is a silicon-based fluid with a distinct molecular structure that dictates its versatile performance. NINGBO INNO PHARMCHEM CO.,LTD. provides this compound, offering valuable insights into its composition and utility.

The molecular formula of Octylheptamethyltrisiloxane is C15H38O2Si3, with a molecular weight of approximately 334.72 g/mol. Structurally, it is a linear trisiloxane featuring a repeating -(Si-O)- backbone, with methyl groups attached to the silicon atoms and a longer octyl (C8H17) chain substituted on one of the central silicon atoms. This combination of short siloxy chains and a longer alkyl chain imparts unique characteristics, such as a lower viscosity compared to longer-chain silicones and good spreading capabilities. Examining the comprehensive CAS 17955-88-3 chemical properties offers a deeper understanding of its behavior.

Physically, Octylheptamethyltrisiloxane typically presents as a transparent liquid. Key physical properties often cited include its refractive index, which is around 1.4128, and a flash point typically above 60°C, indicating a degree of flammability but manageable under standard industrial handling conditions. Its density is also relatively low, contributing to its use in formulations where weight is a consideration. These physical attributes are critical for formulators when determining compatibility and processing parameters.

The industrial relevance of Octylheptamethyltrisiloxane stems from its dual functionality: it acts as an effective silane reagent and provides significant occlusive properties for moisture retention. As a silane reagent, it can be used in surface treatments and as a coupling agent to enhance the compatibility between dissimilar materials. Its role as a silicone fluid that aids in moisture retention is particularly valued in the personal care industry, where it improves skin feel and barrier function. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the quality and consistency of their Octylheptamethyltrisiloxane to support these demanding applications.

In conclusion, Octylheptamethyltrisiloxane is a compound with a well-defined chemical profile that translates into significant industrial benefits.
