Description

[Technical Field]

[0001] The present invention relates to an aerosol-type foam second-agent composition for hair dyeing or bleaching. More specifically, the present invention relates to an aerosol-type foam second-agent composition for hair dyeing or bleaching that has excellent foaming properties under low-temperature conditions and excellent foam retention under high-temperature conditions.

[0002] With the recent rise in fashion consciousness, hair coloring agents, which allow for easy hair color change, have become popular among many people, both men and women. There are various types of hair coloring agents, including permanent hair dyes (oxidative hair dyes and non-oxidative hair dyes), semi-permanent hair dyes (color treatments and hair manicures), bleaches, and temporary colorants, and they are used according to different needs. Among these, oxidative hair dyes or bleaches have excellent hair coloring and bleaching effects, and these properties make them the hair coloring agents currently used by many people.

[0003] Two-component oxidative hair dyes or bleaches, consisting of a first-component composition containing an alkaline agent and a second-component composition containing an oxidizing agent such as hydrogen peroxide, are widely used as oxidative hair dyes or bleaches. Two-component oxidative hair dyes or bleaches are generally liquid or cream-like and are applied to hair using a paintbrush. However, this type of hair dyeing method makes it difficult to apply the dye evenly to the entire hair, and application to the back of the head, where it is difficult to visually check using a mirror, requires a certain level of skill and experience.

[0004] Therefore, in recent years, foam-type oxidative hair dyes or bleaches that can be easily applied to the entire hair have been used. Foam-type oxidative hair dyes or bleaches include aerosol types that use a foaming agent such as liquefied gas, and non-aerosol types that are foamed using a pump foamer or squeeze foamer. Among these, aerosol types have the advantage that they do not require foaming and that any remaining agent can be stored.

[0005] For aerosol-type foam oxidative hair dyes or bleaches, foam persistence (foam retention) is an important issue because dripping may occur if the foam formed by the foaming agent dissipates during the time left on the hair after application. Typical foam compositions often contain components such as polymeric compounds and cationic surfactants to improve foam retention. However, aerosol-type foam hair dye or bleach second-agent compositions contain oxidizing agents, which may decompose these polymeric compounds. Furthermore, when hydrogen peroxide is used as the oxidizing agent, the hydrogen peroxide may be decomposed by the cationic surfactant, which may cause the formulation to become unstable. Therefore, it is preferable that aerosol-type foam hair dye or bleach second-agent compositions contain as few components as possible, such as polymeric compounds and cationic surfactants.

[0006] Therefore, in conventional two-component aerosol foam oxidative hair dyes or bleaches, ingredients such as polymeric compounds and cationic surfactants are blended into the first-component composition to improve the foam retention of the first-component composition, thereby improving the foam retention of the mixture with the second-component composition. However, if the mixture is not uniform, the second-component composition that is not mixed with the first-component composition may defoam, causing dripping. Therefore, there is a need to improve the foam retention of aerosol foam second-component compositions for hair dyes or bleaches. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2019-11292 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-44136 [Patent Document 3] Japanese Patent Application Laid-Open No. 2017-57186 Summary of the Invention [Problem to be solved by the invention]

[0008] Patent Document 1 proposes an aerosol-type foam second-agent composition for hair dyeing or bleaching, which contains an oily ingredient such as a hydrocarbon, with the aim of achieving both formulation stability and improved foam retention at 25°C. However, these oily ingredients increase the viscosity of the aerosol-type foam second-agent composition for hair dyeing or bleaching at low temperatures, such as in winter (hereinafter referred to as low-temperature conditions), which may inhibit rapid foaming. Furthermore, when a liquefied gas is used as the foaming agent, the liquefied gas is difficult to vaporize under low-temperature conditions, which may inhibit rapid foaming. However, Patent Document 1 does not take into consideration foaming under such low-temperature conditions.

[0009] The aerosol-type foam hair dye or bleach second-agent compositions of Patent Document 2 and Patent Document 3 have excellent foaming properties under low-temperature conditions. However, Patent Document 2 does not consider foam retention, and Patent Document 3 only examines foam retention at 25°C. When an aerosol-type foam hair dye or bleach second-agent composition is used in the summer or kept warm using a wrap or hair cap to improve hair dyeing effectiveness, the aerosol-type foam hair dye or bleach second-agent composition is heated by the ambient temperature or the user's body temperature (hereinafter referred to as high-temperature conditions). As a result, the viscosity of the aerosol-type foam hair dye or bleach second-agent composition decreases, defoaming is accelerated, and the aerosol-type foam hair dye or bleach second-agent composition liquefies, potentially resulting in dripping. Therefore, there is a need for an aerosol-type foam hair dye or bleach second-agent composition that has excellent foaming properties under low-temperature conditions and excellent foam retention under high-temperature conditions.

[0010] The present invention has been made in consideration of the above problems, and aims to provide an aerosol-type foam second-agent composition for hair dyeing or bleaching that has excellent foaming properties under low-temperature conditions and excellent foam retention under high-temperature conditions. [Means for solving the problem]

[0011] The present inventors have discovered that the above-mentioned problems can be solved by incorporating a foaming agent into an oxidizing agent-containing aerosol-type foam second-agent composition for hair dyeing or bleaching, which comprises a second-agent aerosol concentrate containing (A) a polyoxyethylene alkyl ether-type nonionic surfactant in which the number of moles of ethylene oxide added is 1, and (B) a polyoxyethylene alkyl ether-type nonionic surfactant other than component (A), and thus have completed the present invention.

[0012] That is, the present invention provides an aerosol-type foam second-agent composition for hair dyeing or bleaching containing an oxidizing agent, (A) a polyoxyethylene alkyl ether type nonionic surfactant having an added mole number of ethylene oxide of 1, (B) a polyoxyethylene alkyl ether type nonionic surfactant other than the component (A), and a foaming agent.
