Abstract
(EN) The present invention provides nanocellulose that has an average fiber width of 1-200 nm and is an oxide of a cellulosic raw material, which does not contain an N-oxyl compound in a cellulose fiber, has excellent dispersion stability in a dispersion medium, and uses hypochlorous acid or a salt thereof, the nanocellulose not substantially containing an N-oxyl compound and having a zeta potential of at most -30 mV.
(FR) La présente invention concerne une nanocellulose qui a une largeur moyenne de fibre de 1-200 nm et qui est un oxyde d'une matière première cellulosique, qui ne contient pas de composé N-oxyle dans une fibre de cellulose, dont la stabilité de dispersion dans un milieu de dispersion est excellente, et qui utilise de l'acide hypochloreux ou un sel de celui-ci ; la nanocellulose ne contenant sensiblement pas un composé N-oxyle et ayant un potentiel zêta d'au plus -30 mV.
(JA) 本発明は、N-オキシル化合物をセルロース繊維中に含んでおらず、かつ分散媒中での分散安定性に優れる、次亜塩素酸又はその塩によるセルロース系原料の酸化物であり、平均繊維幅が1nm以上200nm以下であるナノセルロースであって、N-オキシル化合物を実質的に含まず、ゼータ電位が-30mV以下である、ナノセルロースを提供する。
