7.Description:
(en)FIELD OF THE INVENTION
The present invention generally relates to a second agent composition for hair dyeing or bleaching which is used by being mixed with a first agent composition that includes an alkali agent and is excellent in firmness/resilience and manageability of hair after a dyeing or bleaching treatment.
BACKGROUND OF THE INVENTION
A process in which a first agent composition that includes an alkali agent is mixed with a second agent composition that includes hydrogen peroxide immediately before use, and then, the resulting hair cosmetic is applied to hair to dye or bleach hair is known as a process for hair dyeing or bleaching. In recent years, hair dyeing or bleaching became common and a higher dyeing or bleaching power is demanded.
On the other hand, hair is damaged due to chemical influences caused by hair dyeing or bleaching, as a result, firmness/resilience of hair is sometimes reduced and manageability of hair is sometimes lost after a dyeing or bleaching treatment.
A composition that includes a cationic polymer is studied so as to obtain manageability of hair after a dyeing or bleaching treatment (Patent Documents 1 and 2). However, the composition has to include a large amount of the cationic polymer in order to obtain good manageability. In addition, a large quantity of the cationic polymer sometimes hardens hair, causing a creaking of hair depending on the type of hair.
In order to increase a dyeing or bleaching power, an attempt to sufficiently accelerate the effect of an oxidizing agent by adding an oil to a hair cosmetic was made (Patent Documents 3 to 7). However, the previous hair cosmetics do not achieve sufficient firmness/resilience and manageability of hair after a dyeing or bleaching treatment.

The pH of the first agent composition is preferably from 8 to 12 and more preferably from 9 to 11 from the view point of dyeing or bleaching power and skin irritation. In addition, the pH of the dyeing or bleaching agent composition obtained by mixing the first agent composition with the second agent composition is preferably from 8 to 12 and more preferably from 8 to 10 from the view point of dyeing or bleaching power and skin irritation.
The composition according to the present invention can be used by being mixed with the first agent composition in a usual process depending on the dosage form as far as the effect of the present invention is not deteriorated. For example, the process may be appropriately selected from the following processes: a process in which the first agent composition is mixed with the second agent composition to be uniform by the use of a brush, a muddler or a spatula in a tray or the like used as a container, then, the resulting composition is applied to hair by the use of a brush, a comb or a hand, and a process in which the first agent composition and the second agent composition are placed in a container having sufficient capacity, then the container is shaken to obtain a uniformly mixed composition, and the resulting composition is applied to hair by the use of an applicator for application (such as a single nozzle and a comb type nozzle), a brush, a comb or a hand.
The composition is preferably applied to hair at a temperature from 15° C. to 45° C. from the view point of burdens on hair and a human body. The time period for bleaching or dyeing after the application of the composition to hair is appropriately regulated depending on the content of the alkali agent or the oxidizing agent, the kind and amount of the oxidation dye, the amount of the composition applied to hair and a desired degree of dyeing. The time period is usually from 3 to 45 minutes, preferably from 5 to 30 minutes and more preferably from 10 to 30 minutes. Then, after passage of the time period for bleaching or dyeing, the hair is washed and optionally dried as necessary.
