Abstract

"MICROPéROLAS DE SìLICA DE PRECIPITAçãO, COM PROPRIEDADE SENSORIAL NA BOCA, PROCESSO DE PREPAçãO DAS MESMAS, UTILIZAçãO DAS MICROPéROLAS DE SìLICA, E, COMPOSIçõES DENTIFRìCIAS" Micropérolas de sílica de precipitação, com propriedade sensorial na boca, que apresentam: uma superfície específica CTAB de pelo menos 100 m~ 2~/ g, uma absorção de óleo DOP de pelo menos 200 ml/g, um diâmetro mediano de partícula de 50 a 600 Ám, em superfície de 0,5 a 2 partes em peso (expresso em zinco metal) de um derivado do zinco com grau de oxidação "2" para 100 partes em peso de sílica, um pH de 7 a 9, eventualmente de 0,2 a 5 partes em peso de um pigmento branco para 100 partes em peso de sílica. Seu processo de preparação por precipitação, com tratamento do caldo de sílica por um composto solúvel do zinco, fluidificação mecânica do bolo proveniente da separação do caldo de sílica tratada, e secagem por atomização. Sua utilização nas composições dentifrícias, como agente sensorial na boca.
