Abstract

Derivados de chitosán que tienen unidades estructurales de la fórmula I, II y III, en una distribución aleatoria y los ésteres y derivados de los mismos, cuyos derivados de chitosán contienen un total de cuando menos dos unidades estructurales, y, basándose en un mol del derivado de chitosán, del 30 al 100 por ciento molar de unidades estructurales de la fórmula I, del 60 al 0 por ciento molar de unidades estructurales de la fórmula II, y del 30 al 0 por ciento molar de unidades estructurales de la fórmula III, y la suma de los procentajes molares es el 100 por ciento. Estos derivados son adecuados para utilizarse como humectantes y para la prevención de la adherencia a, y/o formación de, depósitos sólidos sobre substratos inorgánicos u orgánicos.
