[0147] Powder Absorption Test

[0148] The powder absorption properties of the soil catchers listed in Tables 1 and 2 were tested on nut oil and tea as examples of oily and aqueous soils, respectively. The liquid was slowly added to 5 g of dirt catcher powder with stirring until a creamy composition was obtained. The amount of liquid absorbed per 100 g of dirt-acquisition powder was determined. The results are listed in Table 3 and Table 4. For comparison, talc was used as reference.

Abstract

A process for treating a laundry item, which comprises contacting the laundry item with a cleaning composition in the form of a solid comprising an insoluble active agent that is capable of binding soil and free dyes, such that soil on the laundry item is bound to the insoluble active agent, and removing the composition from the laundry item, optionally in the absence of water.

Description

technical field [0001] The present invention relates to a method of treating laundry. The invention also relates to laundry cleaning products. Background technique [0002] Laundry cleaning products are well known. Compositions, either in liquid or powder form, are typically added to the washing machine either directly into the drum or via a dispenser and washed in the appropriate manner selected from a number of pre-programmed cycles. Accurate dosing can be a problem, especially when consumers do not read or follow dosing instructions. Laundry composition products have recently become commercially available packaged in films of water soluble polymers. However, alternative approaches using unit dose products are expected. Furthermore, there is a bias in the perception of some consumers that the polymer is not sufficiently dissolved, or that the polymer may dissolve before the product is added to the wash. Also, the product is considered fragile and does not have many fu...
