19 October 2026, São Paulo: Brazil’s health regulator, ANVISA (Agência Nacional de Vigilância Sanitária), has opened a 60-day public consultation on a proposal to add an ingredient identified as E36, derived from the African oil palm Elaeis guineensis, to the country’s official list of recognized active ingredients for pesticides, disinfestant sanitizers, and wood preservatives.
The consultation, Consulta Pública nº 1.431, was signed on October 14, 2026, by Cássia de Fátima Rangel Fernandes, general manager of ANVISA’s Toxicology division (Gerência-Geral de Toxicologia, or GGTOX), acting under authority delegated by the agency’s Despacho nº 75 of July 9, 2026. It was published in the Diário Oficial da União on October 16, 2026. Marcelo Mário Matos Moreira is listed as the rapporteur on the matter. The underlying administrative files are tracked under SEI process 25351.934379/2026-41 and Datavisa process 25351.062733/2026-26.
The proposal takes the form of a draft Instrução Normativa that would amend Instrução Normativa nº 103, issued on October 19, 2021, which holds Brazil’s official roster of active ingredients eligible for use in pesticide, sanitizer, and wood-preservative products. Being added to that list is a prerequisite step, not a product approval: companies cannot register a specific formulated product containing E36 until the ingredient itself is listed, and even after listing, any product using it would still need separate efficacy review from Brazil’s Ministry of Agriculture and Livestock (MAPA) and an environmental risk assessment from the Brazilian Institute of Environment and Renewable Natural Resources (Ibama) before it could reach the market. The consultation notice reviewed for this story does not specify which pest, crop, or formulation type E36 is intended for, nor does it describe the ingredient’s mode of action; that level of technical detail sits in the dossier underlying the proposal rather than in the public notice itself.
Comments can only be submitted through the electronic form on ANVISA’s Participação Social portal, within the 60-day window that begins three business days after the October 16 gazette publication. ANVISA’s notice states explicitly that contributions submitted outside the form or after the deadline will not be considered, and that all submissions received will be made public. Once the window closes, ANVISA’s technical staff will review the input, and the agency’s collegiate board (Diretoria Colegiada) will vote on whether to finalize the listing, with the outcome to be posted on the agency’s site. ANVISA may also consult other interested government bodies to support the technical discussion before a final decision.
This is one of a steady stream of ingredient-listing consultations ANVISA’s toxicology division has issued through 2026, part of a broader, incremental expansion of Brazil’s recognized pesticide active ingredient roster that has included several biologically derived and plant-based substances this year alongside conventional synthetic chemistries.
