Sodium lauryl sulfate is produced in a small family of standard grades, defined by active matter content and physical form:

  • SLS 92% — standard detergent grade, powder or needles
  • SLS 93% — general-purpose grade
  • SLS 94% — higher-active grade with tighter color and odor control
  • SLS 95% — premium grade for toothpaste and high-end personal care
  • SLS 30% — ready-to-use aqueous liquid
  • SDS 97% and SDS 99% — high-purity grades for pharmaceutical and laboratory applications

As a rule of thumb: detergents and industrial cleaners run on 92–93%, personal care and oral care on 94–95%, and laboratories on 97–99%. For help matching a grade to your formula, see our detailed guide on choosing between SLS 92%, 93%, 94% and 95%.
