Sodium Dodecyl Sulfate (SDS) Flakes
Sodium Dodecyl Sulfate (SDS) Flakes are a pure form of sodium lauryl sulfate, used in laboratory detergents and personal care foaming agents. It meets the Chapter 34 Note 3 criteria for organic surface-active agents, with a surface tension reduction below 45 dyne/cm. This product is classified under 3402.39.90 as 'other' anionic, provided it is not a separate chemically defined compound—if pure, it may be excluded by Chapter Note 1(b).
