Abstract: A method for dyeing keratin fibers, including mixing an aqueous dyeing composition containing a dye compound which is an anionic azo dye, a non-ionic azo dye, a salt thereof, or a mixture thereof, and an alkalizing agent having at least one basic functional group whose conjugated acid has a pKa value in a range of 6.0 to 8.0, with a second aqueous composition having a pH in a range of 1 to 6 to yield a ready-to-use composition having a pH in a range of 7 to 12. The method further includes applying the ready-to-use composition onto the keratin fibers and leaving it for a time period in a range of 1 min to 60 min, and rinsing-off the keratin fibers. The alkalizing agent is triethanolamine, 2-[4-(2-hydroxyethyl)-piperazin-1-yl]-ethane-1-sulfonic acid, a salt thereof, or a mixture thereof.

IPC: F04B43/02
Abstract: A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged front a nozzle portion by performing a discharge operation that presses the lid body toward an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber when the discharge operation is released. A coil spring that urges the lid body to an outside of the pump chamber is included in the pump chamber, a diameter of the coil spring is larger than a radius of the lid body, and a deformation amount of the lid body is equal to or more than ⅓ of a diameter of the lid body.
