Description

The present invention relates to an aerosol type hair dye or bleach composition.

Generally, cream-type hair dyes contain an alkaline agent or dye in the first agent, and an oxidizing agent in the second agent. With this cream-type hair dye, the first and second agents are transferred to a tray container before dyeing and mixed at the time of use, and then the hair is dyed. Therefore, there may be cases where the mixture of the first and second agents prepared before dyeing is insufficient or too much. If there is not enough, the first and second agents are mixed again at the time of use and then the hair is dyed. On the other hand, if there is too much, it cannot be stored and must be discarded, which may result in unnecessary work and costs. In addition, in recent years, there has been a demand for hair dyes that are known as "fast-dyeing types" that can dye gray hair in a short time, and in order to achieve "fast dyeing," the first agent often contains high concentrations of alkaline agents and dyes.

On the other hand, cream-type two-component aerosol hair dye or bleach can be used by dispensing only the first and second components from the aerosol container in the amount you want to use, so problems such as "not enough" or "too much" are less likely to occur. Also, if you use a cream-type two-component aerosol hair dye or bleach by taking it into your hands, the hair dye or bleach will get on the aerosol container, making it more likely to slip from your hand. For this reason, it is often used with a brush or similar to avoid getting the hair dye or bleach on your hands.

As such a two-agent aerosol type hair dye or bleach composition, a cream-like two-agent aerosol type hair dye or bleach composition has been disclosed in which a first inner pouch filled with a first agent and a second inner pouch filled with a second agent are stored in a single pressure-resistant container, compressed gas is filled between the inner pouch and the pressure-resistant container, and the first agent and the second agent are ejected simultaneously by applying the same pressure (Patent Document 1).

JP 2014-237621 A

However, while Patent Document 1 takes into consideration the balance of the amounts of the first and second agents dispensed from the aerosol container and the prevention of dripping, it does not consider at all the spreadability of the first and second agents when they are applied to the hair after being dispensed onto the brush. If the spreadability of either the first or second agent deteriorates, it may not be possible to apply the first and second agents evenly to the hair surface. As a result, the first and second agents will not be able to mix in the specified ratio on the hair surface, which may result in unevenness.

Furthermore, in the case of hair dyes, the first agent often contains high concentrations of alkaline agents and dyes. This reduces the stability of the first agent, making it difficult to ensure sufficient stability, especially under high temperature conditions. For example, when transporting a product by land, the temperature inside the vehicle can rise to around 60°C in summer, and the product will be stored at high temperatures for long periods of time. If this condition continues for a long time, if the product is an emulsion, the emulsion structure may be destroyed, causing separation, etc., so technology to improve stability under high temperature conditions is also desired.

The present invention aims to provide an aerosol type hair dye or bleach composition that has good spreadability when applied to hair, is stable under high temperature conditions, and has good hair dyeing properties.

In the present invention, hair dyeability means dyeability, bleachability, or both.

As a result of intensive research conducted by the present inventors to solve the above problems, the present invention provides an aerosol type hair dye or bleach composition, which is characterized by containing (A) at least one selected from polyhydric alcohols and (B) at least one selected from higher alcohols.

The present invention provides an aerosol type hair dye or bleach composition that has good spreadability when applied, stability under high temperature conditions, and hair dyeing properties.

The aerosol type hair dye or bleach composition of the present invention is preferably in a cream form to prevent dripping.

From the viewpoint of hair dyeing properties, the aerosol type hair dye or bleach composition of the present invention must have good spreadability on the hair surface. If the spreadability of either the first or second agent is poor, the first and second agents may not be able to mix in the specified ratio on the hair surface, which may result in uneven dyeing.

The aerosol type hair dye or bleach composition of the present invention can be used as a double-structure aerosol container having a mechanism for simultaneously discharging the first and second agents, in which a first inner pouch filled with a first agent and a second inner pouch filled with a second agent are housed in a single pressure-resistant container and compressed gas is filled between the inner pouch and the pressure-resistant container, or as a double-connected aerosol container having a mechanism for simultaneously discharging the first and second agents, in which two containers are connected together and the first and second agents are filled in the inner bags of pressure-resistant containers each having an inner bag and compressed gas is filled between the inner bag and the pressure-resistant container.

As the above-mentioned double-structure aerosol container and double-connected aerosol container, for example, the double-structure aerosol container described in JP-A-2005-231644 and the double-connected aerosol container described in JP-A-2004-91356 can be used.

The compressed gas used in the aerosol type hair dye or bleach composition of the present invention is not particularly limited, but may be, for example, dimethyl ether, liquefied petroleum gas, nitrogen gas, alternative fluorocarbons, or other gases commonly used in aerosol products, or compressed air. Of these, it is preferable to use nitrogen gas, especially from the viewpoint of safety.

The aerosol type hair dye or bleach composition of the present invention can also be applied using a brush to prevent staining of the hands.

The brush that can be used in the present invention is preferably one with teeth attached to a base-like structure (hereinafter referred to as a trapezoidal brush) since it is necessary to retain the first and second agents ejected from the ejection port of the aerosol type hair dye or bleach composition. The teeth may be attached to only one side of the trapezoidal brush, or may be attached to both sides. Furthermore, it is preferable that the teeth attached to the trapezoidal brush are attached at regular intervals on one side of the trapezoidal brush.

The brush may be, for example, the brush described in JP 2005-97310 A.

The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples.

In the evaluation tests shown in this specification, the components contained in the first and second agents and their contents were varied.

In the evaluation test for "stretchability" shown in the present specification, a double-structure aerosol container having a mechanism for simultaneously discharging the first and second agents was used, in which a first inner pouch filled with the first agent and a second inner pouch filled with the second agent were housed in one pressure-resistant container, and compressed gas was filled between the inner pouch and the pressure-resistant container. 50 g of the first and second agents of the examples shown in the present specification were each filled into the inner bag of the double-structure aerosol container, and the internal pressure applied to the first and second agents between the inner bag and the pressure-resistant container was 0.7 M. A two-agent aerosol type hair dye or bleach composition was prepared by filling compressed nitrogen gas to a viscosity of 100 Pa (25°C), and the first and second agents were discharged onto a platform brush in a 1:1 ratio to a total of 4 g. Using a hair test doll ("Cut Mannequin No. 775N" manufactured by Bealux Co., Ltd.) with hair cut to a length of 25 cm, the hair was combed once from the root to the tip, and the "spreadability" of each of the creams of the first and second agents after application was evaluated based on the following evaluation criteria. In order to make it easier to evaluate "spreadability," Yellow No. 201 (1) was added to the first agent in this test in an amount that did not affect the "spreadability" to make the appearance color yellow, and to provide a distinction from the second agent (appearance color: white).
