Abstract: A cleaning composition comprises:
A) 1% to 10% w/w of a colloid-forming material,
B) 0.5% to 10% w/w of a polymeric thickener,
C) 1% to 60% w/w of abrasive particles, and
D) a bleaching agent.
Preferably, the colloid-forming material is a clay and the polymeric thickener is a copolymer of acrylic acid.
Such a composition can stably suspend the abrasive particles and has the desired rheological properties for a cleaning composition for use on hard surfaces such as ceramic bathroom fittings and toilets.
