Components for Antimicrobial Formulations

Solvents, surfactants, chelants and polymers can play an important role in creating effective antimicrobial formulations. The removal of soils from surfaces is often the first step in this process.

  • Surfactants will lower the surface tension and assist in the wetting and spreading of the active.
  • Solvents aid in the dispersion and dissolution of soils which helps apply the disinfectant to the surface.
  • Chelants help to control divalent cations to help remove tough stains like soap scum and hard water and keep surfactants more soluble, improving performance.
  • Polymers act as dispersants and inhibit scale and soil redeposition, which enables cleaning without residue.

Dow products can be used in accordance with: EPA 40 CFR 180.940 Active and Inert Ingredients for Use in Antimicrobial Formulations (Food-contact surface sanitizing solutions).

  1. The following chemical substances when used as ingredients in an antimicrobial pesticide formulation may be applied to: Food-contact surfaces in public eating places, dairy processing equipment, and food-processing equipment and utensils.
  2. The following chemical substances when used as ingredients in an antimicrobial pesticide formulation may be applied to: Dairy processing equipment, and food-processing equipment and utensils.
  3. The following chemical substances when used as ingredients in an antimicrobial pesticide formulation may be applied to: Food processing equipment and utensils.

Nonfood applications

Dow surfactants, solvents, chelants, and polymers can be used in antimicrobial formulations where there is no food contact. Applications may include bathroom cleaners, hard surface cleaners, cleaning wipes, etc. In addition, all food use inert ingredients noted above are also permitted for nonfood use applications where there is no food contact.

For surfaces that may come in contact with food, a potable water, rinse is required.

*Commodity inerts

EPA has developed a list of inert ingredients it has designated as commodity inert ingredients. Registrants and applicants completing the Confidential Statement of Formula (CSF) Form (EPA Form 8570-4) will no longer need to list the commodity inert ingredient suppliers.
