This invention refers to a pharmaceutical composition of an environmental disinfectant for the dry disinfection of environments based on trichloro isocyanuric acid 90%,Which acts as a disinfectant and moisture absorber in facilities such as: painters, recreations, aviaries, floors, sheds, equipment, drapes, pedigree, grain storage silos etc. Pathogenic microorganisms are capable of producing infectious diseases in their hosts Under conditions favourable to their survival and development, produce toxic compounds and may be transmitted by air or by consumption of food contaminated by inappropriate manipulation and processing, mainly by cross -contamination,Which is the transmission of pathogens from one contaminated food to another innocuous food. The object of the patent was developed with the aim of eliminating as much of these pathogens as possible, even with the existence of organic matter in these environments, which are conducive to its development and proliferation. Because it is sprinkled on the environment through a motor atomizer The environmental disinfectant, which is the subject of this patent, will be in suspension for longer, thus ensuring long -term effectiveness and reaching difficult access places.a presente invenção se refere a uma composição farmoquímica de um desinfetante ambiental para desinfecção a seco de ambientes a base de ácido tricloro isocianúrico 90%, que atua como desinfetante e absorvente de umidade em instalações tais como: pinteiros, recrias, aviários, pisos, barracões, equipamentos, cortinas, pedilúvio, silos de armazenamento de grãos etc. os microrganismos patogênicos são capazes de produzir doenças infecciosas em seus hospedeiros nas condições favoráveis à sua sobrevivência e desenvolvimento, produzem compostos tóxicos e podem ser transmitidos pelo ar ou pelo consumo de alimentos contaminados por manipulação e processamentos inadequados, principalmente pela contaminação cruzada, que é a transmissão de patógenos de um alimento conta
