São Paulo’s Law No. 15.316/2014 established the first state-level cosmetic animal testing prohibition in Brazil, creating a legislative template replicated across subsequent states. Amazonas Law 289/2015 (promulgated 3 December 2015) was the first state law to face a federal constitutional challenge, with ABIHPEC filing ADI 5.996 in September 2018; the STF upheld it unanimously in April 2020. Pará Law 8.361 (signed 2016) prohibited testing of finished cosmetics and cosmetic ingredients on animals within Pará. Rio de Janeiro Law 7.814/2017 (15 December 2017) added commercialisation and labelling provisions beyond the testing ban; the STF upheld the testing ban (10–1) but struck the commercialisation and labelling provisions (6–5) in May 2021. By 2017–2018, bans were in force across Amazonas, Mato Grosso do Sul, Minas Gerais, Pará, Paraná, Pernambuco, Rio de Janeiro, São Paulo, Santa Catarina, and the Federal District. NGO estimates placed the covered states at hosting over 70% of Brazil’s cosmetics industry. No official consolidated dataset quantifying changes in animal testing volumes or facility counts during this period is available in sources consulted. The constitutional validity of the state bans was progressively confirmed by the STF in 2020–2021.

Anticipated Effects

If implemented as written and enforced across adopting states, the bans would eliminate the use of animals for cosmetic product and ingredient testing in laboratories and company facilities physically located in those states, encouraging adoption of validated alternative test methods or relocation of testing to jurisdictions without equivalent bans.

Whether the wave of state bans produced a net reduction in cosmetic animal testing nationally — versus displacement of testing to states without bans or to other countries — is not established in available sources; empirical data on testing volumes before and after individual state laws are not reported in sources consulted.

Significance Rationale

Assigned Reduces Exploitation (impact direction) because the state laws remove legal authorisation for animal cosmetic testing within their territories, converting a previously permitted use of animals in those jurisdictions into prohibited conduct. Collectively, the states with operative bans hosted approximately 70% of Brazil’s national cosmetics industry by 2017–2018.

Assigned Alters Legal Basis (impact type) because each state law changes what is legally permissible within its jurisdiction — converting previously allowed cosmetic animal testing activities into prohibited conduct. This is a direct legal prohibition, not a modification of conditions within a continuing system.

Assigned Moderate significance because individually each state ban affects one jurisdiction and one sector. The collective geographic reach — states hosting approximately 70% of Brazil’s cosmetics industry — elevates the combined significance above any single state ban while remaining below a national prohibition. The bans do not address animal use in pharmaceuticals, agrochemicals, or other research sectors; federal law permitting scientific animal use continued in force throughout 2014–2018.

The duration and persistence of the scale change in cosmetic animal testing across the affected states is not established in available sources; no quantitative data on animal testing volumes before or after the individual state laws are reported in sources consulted.
