US EPA Bans Eight Inert Ingredients From Organic Use

Avatar for Matt Hopkins By Scott C. Lucas|20 September 2007

NOP regulations allow the use of inert ingredients appearing on two lists which EPA maintains. However, according to NOP, those lists "may no longer be effective or available" following last year’s reassessment of inert ingredients in pesticide products to ensure that they meet the safety standard established by the Food Quality Protection Act (FQPA).

The inert ingredients that have been revoked for use in pesticide formulations and are now prohibited under NOP are as follows:

  • Acetylated lanolin alcohol (CAS Reg. No. 91994-94-4).
  • Acrylic acid methyl ester, polymer with acrylonitrile and 1,3-butadiene (CAS Reg. No. 27012-62-0).
  • Coumarone – indene resin (CAS Reg. No. 63393-89-5).
  • Manganous oxide (CAS Reg. No. 1344-43-0).
  • Pentaerythritol monostearate (CAS Reg. No. 78-23-9).
  • Pentaerythritol tetrastearate CAS Reg. No. 115-83-3).
  • Polyglyceryl phthalate ester of coconut oil fatty acid (CAS Reg. No. 66070-87-9).
  • Sodium fluoride (CAS Reg. No. 7681-49-4).
