P410+P412 is the GHS precautionary statement “Protect from sunlight. Do not expose to temperatures exceeding 50°C/122°F”. UN GHS Annex 3 assigns it to Aerosols (chapter 2.3), Category 1, 2, 3.

Ne pas exposer à une température supérieure à 50 °C/122 °F” and Mexico’s Spanish text is “Proteger de la luz solar. No exponer a una temperatura superior a 50 ºC / 122 ºF”.
