Abstract

método de limpeza da roupa para lavar e uso de uma composição de pré-tratamento a presente invenção refere-se a um método de limpeza da roupa para lavar que compreende as etapas de: (i) pré-tratamento da roupa para lavar com uma composição de pré-tratamento líquida; e (ii) lavagem da roupa para lavar assim pré-tratada em um líquido de lavagem compreendendo uma formulação detergente de lavagem principal, preferivelmente, um detergente em pó de lavagem principal. a composição de pré-tratamento líquida usada no dito método compreende (a) 0,005 a 20 % em peso de hidroxamato e (b) 3 a 80 % em peso de sistema tensoativo detersivo, em que a razão em peso entre a) e b) se encontra na faixa 6:1 e 1:16000, preferivelmente 1:10 a 1:400. verificou-se que a detergência aumentada, em particular com relação à remoção de manchas de sujeiras particuladas, pode ser obtida ao aplicar o método da presente invenção.The method of cleaning the laundry and use of a pretreatment composition The present invention relates to a method of cleaning the laundry comprising the steps of: (i) pretreatment of the laundry with a composition liquid pretreatment; and (ii) washing the laundry thus pre-treated in a washing liquid comprising a main wash detergent formulation, preferably a main wash detergent powder. the liquid pretreatment composition used in said method comprises (a) 0.005 to 20 wt% hydroxamate and (b) 3 to 80 wt% detersive surfactant system, wherein the weight ratio between a) and b) is found in the range 6: 1 and 1: 16000, preferably 1:10 to 1: 400. It has been found that increased detergency, in particular with respect to the removal of stains from particulate dirt, can be obtained by applying the method of the present invention.
