Abstract

"DISPERSãO AQUOSA CONTENDO PARTìCULAS DE óXIDO METáLICO PIROGENICAMENTE PREPARADAS E DISPERSANTES". A presente invenção refere-se a uma dispersão aquosa que contém partículas de titânio, zinco, ferro ou cério em forma de óxido pirogenicamente preparadas com um tamanho médio de partículas, expressas como mediana, na dispersão menor que 250 nm, caracterizada pelo fato de que os tamanhos das partículas do óxido na dispersão não se distribuem simetricamente e a dispersão contém, como um dispersante, pelo menos um composto de fórmula (I) e/ou um copolímero de anidrido maléico/acrilato de fórmula geral (IIa) e/ou um copolímero de maleato/acrilato de fórmula geral (IIb) A dispersão é preparada dispersando uma corrente de pré-dispersão por meio de um moinho de alta energia. Ela pode ser usada em formulações de filtro solar.
