Abstract

método para fabricação de grânulos de resina, grânulos de resina e produto que emprega grânulos de resina. a presente invenção fornece um método para a produção de grânulos de resina que podem fornecer vários tipos de produtos, tais como cosméticos, transmitidos por impressão tátil superior, capacidade de espalhamento na pele, transparência e estabilidade de produto, e que podem ser substituídos por partículas de resina compostas por um material sintético derivado do petróleo. o método é um método para a produção de grânulos de resina contendo um derivado de celulose como componente principal. o método de produção inclui: uma etapa de preparação de suspensão de mistura de uma fase oleosa contendo o derivado de celulose e um solvente orgânico que dissolve o derivado de celulose, o solvente orgânico tendo uma solubilidade em água de 0,1 a 50,0 g e uma fase aquosa contendo um estabilizador de dispersão, preparando assim uma suspensão contendo gotículas de óleo contendo o derivado de celulose e o solvente orgânico; e uma etapa de contração de gotículas de óleo de adição de água à suspensão, contraindo assim as gotículas de óleo, em que a água é adicionada à suspensão de modo a satisfazer a seguinte expressão (a) até que um teor do solvente orgânico na suspensão torna-se igual ou inferior à solubilidade em água do solvente orgânico. (w/s)/t1.00 (a), em que w: uma quantidade adicional de água (partes por massa), s: uma quantidade da suspensão (partes por massa), e t: um tempo (minutos) necessário para a adição.
