DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a mixing-at the time of use-type hair-treating composition. More specifically, the invention relates to a hair dye composition and a hair-bleaching agent composition each containing particular components in such a state that they are combined.
BACKGROUND ART
Heretofore, as mixing-at the time of use-type (namely, two or more agents are combined at the time of use) hair-treating compositions, particularly hair dyes and hair-bleaching agents, twin pack ones have usually been used, and a typical hair-treating composition is one formed by mixing the first agent containing as a principal agent an oxidation dye including an aromatic amino compound and/or an alkalinizing agent such as ammonia with the second agent containing as a principal agent an oxidizing agent such as hydrogen peroxide at the time of use. This mixture is applied onto hair at the time of use, and therefore the mixture is required to have a viscosity of such a degree that it does not drip from the hair. Thus in prior art, a thickening system at the time of mixing has been obtained by utilizing the crystalline region of an aqueous nonionic surface active agent solution. Namely, a. thickening system has been obtained by diluting the first agent wherein a thick nonionic surface active agent having a concentration equal to or higher than the liquid crystal formation concentration and a lower alcohol are compounded together with a dye or an alkalinizing agent, with the second agent containing an oxidizing agent to adjust the concentration of the surface active agent in the final mixture to its liquid crystal region. However, particularly as to dyeing agents, usual systems wherein nonionic surface active agents and lower alcohols are thick had drawbacks that the hair after dyeing is dry to the touch, and since it becomes liquid crystals at the time of mixing, dispersion of the dye is bad and its dyeability is bad.
On the other hand, for the purpose of providing a hair dye making dyeing of hair or giving it a color tone, and at the same time washing and conditioning possible, a hair dye is proposed which contains a cationic polymer, an anionic surface active agent, and an amphoteric or amphoteric ionic surface active agent, in specific rates, respectively (for example, see Japanese Patent Publication No. 22884/1992).
However, it has been difficult to stably provide such a hair dye or hair-bleaching agent that in the preparation compositions before mixing in a separated form, they are stable in physical properties and exhibit relatively low viscosities, but at the time of use, namely when all the components are mixed, the mixed composition does not drip from the hair, and that it is excellent in desired dyeing or decolorization, and the touch of the hair after deying or decolorization, etc.
For example, as to the above composition wherein a lower alcohol was used, there was a tendency that the touch of hair after such treatment is poor.
Thus, the object of the invention lies in providing such a mixing-at the time of use-type hair-treating composition that from a composition at the time of use wherein respective components are mixed, part or all of the lower alcohol can be removed, and moreover when the respective components are independent with one another or in such a form that they are separated as certain groups, they relatively exhibit low viscosities, but when the respective components are combined to be in a mixed state, the mixture exhibits a moderate viscosity.
DISCLOSURE OF INVENTION
It is known that although it does not belong to the technical field of hair dyes, a composition containing an anionic surface active agent, an amphoteric surface active agent and/or a semipolar surface active agent, and a higher fatty acid has, as a skinwashing agent, a moderate viscosity (For example, see Japanese Laid-open Patent Publication No. 17342/1993 and Japanese Laid-open Patent Publication No. 65596/1994).
The present inventors found that as to the respective components of such a composition, when they are
