Abstract

La presente invención se refiere a un método para medir la dureza de un tensoactivo, caracterizado porque comprende los pasos de: 1) preparar un complejo sólido de proteína-colorante que comprende: a) una proteína, que es una proteína de maíz no desnaturalizada y que es soluble en alcohol acuoso; y b) un colorante de unión a proteínas, que es específico a la proteína (a); al disolver a) y b) en alcohol acuoso para formar una solución de proteína-colorante; y retirar el alcohol acuoso para formar un complejo sólido de proteína-colorante; y ii) proporcionar una solución acuosa de tensoactivo y tomar una primera medición de color; iii) agregar el complejo sólido de proteína-colorante a la solución de tensoactivo, tomar una segunda medición de color y medir el cambio de color entre la primera medición de color y la segunda de color; y iv) hacer coincidir el cambio de color con una escala de referencia.
