Title (EN) STABLE BLEACHING COMPOSITIONS
(FR) COMPOSITIONS DE BLANCHIMENT STABLES
Abstract: front page image
(EN)The present invention relates to liquid bleaching composition comprising a hypohalite bleach and an alkyl (alkoxy)¿n? sulphate, with an average ethoxylation degree n ranging from 0.1 to 20, characterised in that said alkyl (alkoxy)¿n? sulphate contains less than 10 % by weight of unsulfated material on the alkyl (alkoxy)¿n? sulphate active basis and/or less than 0.0015 % by weight of heavy metal impurities on alkyl (alkoxy)¿n? sulphate active basis and/or an amount of inorganic salts or alkali such as their contribution to the ionic strength of the alkyl (alkoxy)¿n? sulphate raw material solution is of less than 0.5 moles/kg and/or less than 0.5 % bisulphite salts on alkyl (alkoxy)¿n? sulphate active basis. These compositions exhibit excellent stain removal performance while delivering excellent chemical stability upon ageing.
(FR)La présente invention concerne une composition de blanchiment liquide. Cette composition comprend un agent de blanchiment d'hypohalite et un sulphate d'alkyl(alcoxy)¿n?, avec un degré d'éthoxylation moyen n situé entre 0,1 et 20. Cette composition se caractérise en ce que ce sulphate d'alkyl (alcoxy)¿n? contient moins de 10 % en poids de matériau non sulphaté sur la base active de sulphate d'alkyl (alcoxy)¿n? et ou une quantité de sels inorganiques ou d'alcali telle que leur contribution à la résistance ionique de la solution de matière première de sulphate d'alkyl (alcoxy)¿n? est inférieure à 0,5 moles/kg et/ou contient moins de 0,5 % de sels bisulfitiques sur la base active de sulphate d'alkyl (alcoxy)¿n?. Ces compositions présentent une excellence propriété d'élimination des tâches tout en assurant une excellente stabilité chimique lors du vieillissement.
