Abstract

Una composición blanqueadora que comprende un ligando orgánico que forma un complejo con un metal de transición para blanquear un substrato con un grupo seleccionado entre: a) oxígeno atmosférico, al agregar la composición blanqueadora a un medio acuoso, la misma brinda un medio de blanqueo acuoso substancialmente desprovisto de un blanqueador de peroxígeno o un sistema de blanqueo generador de peroxilo o a base de peroxi; y b) un blanqueador de peroxígeno o fuente del mismo, junto con un surfactante que tiene un hidrógeno alílico, dicho surfactante tiene un HLB superior a 2, y al menos dos antioxidantes, mediante lo cual la combinación al menos de los dos antioxidantes brinda, en una solución que contiene ácido oleico, una reducción eficaz de la formación de hexanal a partir de ácido oleico bajo condiciones atmosféricas ambientales, en un factor al menos de tres, en comparación con la misma composición blanqueadora que tiene un equivalente molar de un único antioxidante equivalente a la concentración molar combinada al menos de ambos antioxidantes, y dicho único antioxidante es uno al menos de ambos antioxidantes. El objeto de la presente es brindar una composición que reduzca el problema de mal olor.
