The present patent application relates to a process for preparing a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising a step of mixing several identical or different solid particles comprising one or more dyes, preferably one or more oxidation dye precursors, with an oxidizing aqueous composition, followed by a step of adding an alkaline aqueous composition preferably comprising arginine. The present patent application also relates to a dyeing process using the composition obtained.

A method of making a foaming deodorant containing an aqueous solution of citric acid, aloe vera gel, capryl capryl glucose, hydrogen peroxide, and witch hazel. The foaming deodorant may also have an essential oil, a fragrance, and/or a color. The foaming deodorant is added to a dispensing container and dispensed from a pressurized dispensing container or from a dispensing container having a dispensing pump. Citric acid and hydrogen peroxide safely kill bacteria on the skin. The foaming deodorant may be used anywhere on the skin of the body.
