How surfactants work
Surfactants assist wetting and soil removal, but selection depends on the whole system.
Read article01 / THE IDEA
Nonionics offer options for wetting and removal of particular soils.
Nonionic does not mean unaffected
Nonionic surfactants have no net charge on the hydrophilic group under typical conditions, yet may improve wetting and removal of certain soils. Their chemistry varies, as do foaming and solubility. Some ethoxylated nonionics show a temperature-dependent cloud point, also influenced by salts and other ingredients; the behavior is not identical across the family.
Choose the grade for the task
Nonionics may suit lower-foam processes or specific soil-removal needs, alone or in blends. Check expected storage and use temperatures for clarity, dissolution and cleaning, and examine substance-specific safety and environmental data. The nonionic label by itself does not establish suitability for every application.
How would this be tested?
Test a candidate nonionic at expected storage and operating temperatures while following clarity and dissolution. If haze appears, inspect the exact grade, salts, perfume and solvent before rejecting the whole chemical family. Measure removal of representative soil separately from bottle clarity: appearance changes do not directly quantify oil removal. Compare foaming and rinsing where the process requires low foam.
Practical evaluation checklist
01
Match selection to soil and use temperature.
02
Check solubility and cloud point where relevant.
03
Evaluate foam in the finished system.
