EPA Loosens Rules on Sulfonic Acids for Food-Safe Pesticides
Published Date: 2/13/2026
Rule
Summary
The EPA just made it official: certain sulfonic acids used as surfactants in pesticides on food-contact surfaces don’t need a residue limit anymore. This helps food and pesticide makers by cutting red tape starting February 13, 2026, with a chance to raise concerns by April 14. If you work with food processing or pesticides, this rule makes your life a bit easier and could save some money on compliance.
Analyzed Economic Effects
1 provisions identified: 1 benefits, 0 costs, 0 mixed.
1% Surfactant Tolerance Exemption
If you make or use pesticides or work in food processing or dairy equipment, EPA says residues of sulfonic acids (sodium C14-C16 AOS) do not need a numerical tolerance when used as a surfactant on food-contact surfaces so long as the ingredient is no more than 1% of the final pesticide formulation. The rule is effective February 13, 2026; EPA will not require an analytical enforcement method and will not register any food-use pesticide formulation that exceeds 1%, and objections must be filed by April 14, 2026.
