Abstract

''CIGARRO COM FILTRO E PROCESSO DE FABRICAçãO DE UM CIGARRO COM FILTRO'', dito filtro a) contém material filtrante em forma de fibra, b) contém um aditivo com efeito antimutagênico à fumaça do cigarro em uma quantidade menor que 15% da massa, referente ao peso de fibra do filtro, e c) no teste de fumar de um cigarro com filtro não ventilado do mesmo tipo, entretanto não contendo aditivo, apresenta uma retenção de nicotina R~ N~ (em %) (determinada conforme CORESTA, método recomendado n. 9), a qual concluí-se com a seguinte fórmula: R~ N~ <242> 100 * (1-D), onde vale: D = exp (A * B + C), com A = 21 mm - comprimento do filtro (mm) para comprimentos de filtro <243> a 25 mm, respectivamente, A = -4 mm para comprimentos de filtros > 25 mm, B = 9,3 * 10^ -3^ (1/mm) e C = - (d^ 4^ * <30>~ p~ * K + L) com d = diâmetro de filtro (mm), <30>~ p~ = resistência à tração de filtro (mmWS), K = 1,0228 * 10^ -6^ (1/(mm^ 4^ * mm WS)) e L = 0,2334. Com este filtro, medido conforme teste de Ames com linhagem TA 98, podem ser filtradas substâncias ativas mutagenicamente com uma seletividade de pelo menos 10 % melhor do que outras substâncias contidas na fumaça. Além disso, foi descrito um processo apropriado, em especial, para a fabricação de um cigarro com filtro semelhante.
