CA 2353958

A non-bleaching laundry detergent composition comprises surfactant, builder, and optionally other non-bleach detergent ingredients, and also contains from 0.05 to 2.5 wt.% of iminodisuccinate (IDS) or hydroxyiminodisuccinate (HIDS). The composition provides improved maintenance and/or restoration of colour fidelity during the wash, especially at low wash pH. The IDS or HIDS is also an effective chlorine scavenger, reducing the in-wash fading of chlorine- sensitive dyes. In addition, the incorporation of the IDS or HIDS improves the stain removal performance of the composition.

L'invention concerne une composition de détergent à lessive non décolorante comprenant un tensioactif, un adjuvant et éventuellement d'autres ingrédients de détergent non décolorants, ainsi qu'une quantité comprise entre 0,05 et 2,5 % en poids d'iminodisuccinate (IDS) ou d'hydroxyiminodisuccinate (HIDS). La composition permet d'obtenir une meilleure conservation et/ou restitution des couleurs lors du lavage, en particulier avec un pH de lavage faible. Les IDS ou HIDS sont également des capteurs de chlore efficaces, qui réduisent la décoloration lors du lavage de colorants sensibles au chlore. En outre, l'ajout d'IDS ou de HIDS améliore les propriétés détachantes de la composition.
