Sodium Decyl Sulfate (SDS), identified by CAS No. 142-87-0, is an anionic surfactant characterized by its molecular formula C10H21NaO4S. Understanding its physical and chemical properties is key to appreciating its diverse applications across various industries.

Visually, SDS presents as a yellow transparent liquid. This appearance is indicative of its purity and formulation. The typical properties detailed by manufacturers often include specifications for its active substance content, typically ranging between 28.0% and 30.0%, and solid contents between 34.0% and 36.0%. These parameters are crucial for formulators to accurately calculate usage concentrations in their products, whether for cosmetic ingredient formulations or industrial detergents.

The pH value of Sodium Decyl Sulfate solutions generally falls within the range of 7.0 to 11.0%, indicating a slightly alkaline to alkaline nature. This pH range is often suitable for many cosmetic and cleaning applications, contributing to the overall effectiveness of the final product. Furthermore, its density typically ranges from 1.065 to 1.120%, providing important physical data for handling, storage, and transport calculations, crucial for both household detergent components and industrial chemical emulsifiers.

These properties collectively define Sodium Decyl Sulfate as a highly functional chemical. Its surfactant capabilities, combined with its specific physical attributes, make it an indispensable ingredient for achieving desired performance in a wide array of products. Sourcing high-quality SDS from reliable sodium decyl sulfate manufacturers is essential for ensuring these properties are met, leading to predictable and effective outcomes in formulation. The detailed understanding of these characteristics is fundamental for any professional working with this versatile compound.
