Introduction

Wetting agents play a crucial role in various industries such as agriculture, pharmaceuticals, and cleaning products. They are chemical substances that reduce the surface tension of water, allowing it to spread more easily across surfaces or to penetrate the surface of solids. This article discusses common wetting agents, their applications, and solutions provided by Topwin Company.

Common Wetting Agents

Wetting agents are used to enhance the effectiveness of formulations by improving the spreadability and penetration of liquids. Below are examples of commonly used wetting agents along with their key parameters:

  • Sodium Lauryl Sulfate (SLS):
    • CAS Number: 151-21-3
    • Critical Micelle Concentration (CMC): 8.2 x 10-3 mol/L
    • Applications: Detergents, shampoos, emulsifiers
  • Alkylbenzene Sulfonates:
    • Typical Chain Length: C10-C14
    • CMC: 1.0 x 10-2 mol/L
    • Applications: Household cleaning, emulsifiers
  • Nonylphenol Ethoxylates (NPE):
    • CAS Number: 9016-45-9
    • CMC: Depends on ethoxylation degree; typically 10-30 ethylene oxide units
    • Applications: Industrial cleaning, textile processing
  • Polyoxyethylene Sorbitan Esters (Tweens):
    • Molecular Weight Range: 400-1500
    • Hydrophilic-Lipophilic Balance (HLB): 10-18
    • Applications: Pharmaceuticals, food emulsifiers
