A coloring product for dyeing or refreshing dyes in textile materials is disclosed. The coloring product includes a flat carrier material, at least one coating applied to the carrier material, and at least one dye in the coating. The at least one dye is present in a quantity ranging from 45% by weight 98% by weight in relation to the overall quantity of the coating. The flat carrier material is a nonwoven. The coloring product may be included in a washing machine that has textile materials in an aqueous solution at a temperature of at least 20° C. over a period of at least 10 minutes.

A laundry care composition including (a) at least one laundry care ingredient and (b) a leuco composition. The leuco composition has a first color state and a second color state and the mole ratio of second color state to first color state is from 2:98 to 5:95. Also disclosed are methods of determining the approximate functional age of a laundry care composition comprising the steps of (a) providing a laundry care composition that includes at least one laundry care ingredient and a leuco composition, (b) providing a functional age scale that includes a plurality of distinct colors that correspond to a unique functional age and (c) comparing the color of the laundry care composition with the functional age scale.

Disclosed herein is a chemical dosing system for an appliance, such as a laundry washing machine or a dishwashing machine, having a water inlet, the system comprising a meter determining the volume of water supplied to the appliance, a pump for dispensing a quantity of a chemical to the appliance and a control unit arranged to receive a signal from the meter and to cause to be dispensed to the appliance a volume of chemical that is proportional to the quantity of water supplied to the appliance. The disclosed system may enable a correct quantity of chemical to be automatically dispensed to many types of appliance, without the need to know anything about the appliance, or to derive an electrical signal from the appliance.

The present invention provides acidic or basic cleaning compositions for use in cleaning food and beverage industry processing equipment and pharmaceutical and cosmetic industry processing equipment wherein the compositions of the invention comprise a food-equipment-safe acidic or basic cleaning compound and a food-equipment-safe colorimetric indicator of pH to show the desired acid or basic conditions during storage prior to the start of a cleaning cycle and after storage and during a cleaning cycle. The cleaning compositions of the invention are particularly useful in, for example, CIP cleaning processes.
