For any B2B professional involved in sourcing chemical raw materials, a thorough understanding of product specifications is non-negotiable. Sodium Dodecyl Benzene Sulfonate (SDBS) powder, a ubiquitous anionic surfactant, is no exception. As a leading manufacturer and supplier of SDBS powder from China, we recognize the importance of clarity in product data to empower your purchasing decisions. This guide will break down the key specifications of SDBS powder, ensuring you can effectively evaluate and select the right product for your specific needs.

Key Specifications of SDBS Powder Explained

When you are looking to buy SDBS powder, you will commonly encounter several critical parameters. Understanding these will help you communicate your requirements clearly to your supplier and ensure product suitability:

  • Appearance: SDBS powder is typically described as a white or light yellow powder. Deviations from this can sometimes indicate variations in the manufacturing process or potential impurities. A consistent appearance is a good indicator of product quality from a reputable manufacturer.
  • Active Content (Active Matter): This is perhaps the most crucial specification. It refers to the percentage of actual SDBS present in the product. Common grades range from 60% to 90% active content. A higher active content means a more concentrated and potent surfactant, which can influence the dosage required in your formulations. Ensure your supplier clearly labels the active content (e.g., LAS-60, LAS-80, LAS-90).
  • CAS Number and Molecular Formula: The CAS number (25155-30-0) and molecular formula (C18H29NaO3S) are unique identifiers for Sodium Dodecyl Benzene Sulfonate. These are essential for regulatory compliance and for cross-referencing information from different suppliers.
  • pH Value: Typically, the pH of a 1% aqueous solution of SDBS powder falls within the range of 7.0 to 10.5. This indicates its mildly alkaline nature, which is compatible with many detergent formulations.
  • Water Content: Low moisture content is desirable for powder products to ensure stability and prevent caking. Specifications usually list a maximum water percentage, often around 5.0%.
  • Apparent Density: This refers to the bulk density of the powder. While not always a primary concern for performance, it can be relevant for packaging and handling. An apparent density of around 0.18 g/ml is common.
