Abstract
La invención se refiere a la utilización de ácidos orgánicos añadidos por separado o a posteriori, en particular de ácido cítrico, para la supresión de manchas blanqueables sobre textiles, cuando el detergente utilizado está prácticamente libre de agentes de blanqueado. Se utilizan para este fin detergentes granulares con una masa volumínica a granel de entre 650 g/l a 1100 g/l en peso que contienen agentes tesioactivos aniónicos, o no iónicos, así como adyuvantes para detergentes, incluido 1 a 15% en peso de un ácido orgánico añadido por separado o a estando el detergente prácticamente libres de agentes de blanqueado. Las ventajas de estos agentes se hacen evidentes cuando dicho detergente se utiliza en lavadoras a temperaturas, como máximo de 60ºC, en particular a temperaturas aproximadamente cercanas a entre 30 y 40ºC.
