(57) Abstract: A non-beaching 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)
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.
