Description

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

A general cream-like hair dye contains an alkaline agent and a dye in the first part, and an oxidizing agent in the second part. Before dyeing the hair, the first part and the second part of this creamy hair dye are transferred to a tray container and mixed at the time of use, and then the hair is dyed with a brush. Therefore, the mixed solution of the first agent and the second agent prepared before hair dyeing may be insufficient or excessive. If the amount is insufficient, the first agent and the second agent are mixed again before use, and the hair is dyed with a brush. On the other hand, if there are too many, they cannot be kept and must be discarded, which may result in wasted work and cost. In recent years, there has been a demand for a “quick dyeing type” that dyes gray hair in a short period of time. often do.

On the other hand, a cream-like two-part aerosol type hair dye or bleaching composition is produced by ejecting the first part and the second part directly onto the brush, and then holding the first part and the second part on the brush. Apply directly to hair to dye. Therefore, you can dye your hair without getting your hands dirty, and you can use as much of the first agent and second agent as you want to use from the aerosol container. problem is less likely to occur. Also, by using a brush, the first and second agents do not stick to your hands, so when you pick up the aerosol container or press the button of the aerosol container to discharge the first and second agents. There is no need to worry about the aerosol container slipping out of the hand.

As such a two-part aerosol type hair dye or bleach composition, the first inner pouch filled with the first part and the second inner pouch filled with the second part are placed in one pressure container, and the inner A creamy two-component aerosol type hair dye or decolorant composition is disclosed in which a compressed gas is filled between a pouch and a pressure-resistant container, and the same pressure is applied to simultaneously discharge the first and second components. (Patent document 1).

However, in Patent Document 1, although the balance between the amounts of the first agent and the second agent ejected from the aerosol container and the suppression of dripping are taken into consideration, the first agent and the second agent ejected to the brush are considered. No consideration is given to the spreadability of each of the first agent and the second agent when the two agents are applied to the hair. If the spreadability of either the first agent or the second agent is poor, there is a possibility that the first agent and the second agent cannot be uniformly applied on the hair surface. Therefore, the first agent and the second agent cannot be mixed at the predetermined ratio on the surface of the hair, and as a result, unevenness may occur.

In the case of hair dyes, the first agent often contains a high-concentration alkaline agent or dye. Therefore, the stability of the first agent is lowered, and it tends to be difficult to ensure sufficient stability especially under high temperature conditions. For example, when commodities are transported by land, the temperature inside the vehicle rises to about 60° C. in the summer, and the commodities are stored in a high temperature state for a long period of time. If this state continues for a long time, if the product is an emulsion, the emulsion structure may be destroyed and separation may occur. Therefore, a technique for improving stability under high temperature conditions is also desired.

Accordingly, the present invention provides an aerosol-type hair dye or bleach composition in which both the first agent and the second agent have good spreadability when applied to the hair, and the first agent and the second agent are applied under high temperature conditions. To provide an aerosol type hair dye or decolorant composition which is both stable and has good hair dyeing properties.

In addition, the hair dyeing property in the present invention means dyeing property, bleaching property or both.

As a result of intensive studies to solve the above problems, the present inventors have found an aerosol-type hair dye or bleaching composition comprising (A) glycerin, polyethylene glycol, and dipropylene glycol for both the first agent and the second agent. , at least one or more selected from diglycerin and 1,3-butylene glycol, (B) a higher alcohol having 16 to 22 carbon atoms, (C) a nonionic surfactant, and further, the first agent and the second agent For both of the two agents, the weight ratio (B)/((C)+(D)) of at least one selected from the above component (C) and (D) cationic surfactant to the above component (B) is 0.00. An object of the present invention is to provide an aerosol type hair dye or decolorant composition characterized by having 5 to 7.

According to the present invention, it is possible to obtain an aerosol type hair dye or decolorant composition that has good spreadability when applied, good stability under high temperature conditions, and good hair dyeing properties.

◎: No separation after storage for 24 hours at 60°C ○: No separation after storage for 24 hours at 60°C although there is slight water removal △: Some water is removed after storage for 24 hours at 60°C No separation ×: Separation after storage for 24 hours at 60°C

[Hair dyeing property]
In the evaluation test related to the "hair dyeability" shown in this specification, the first inner pouch filled with the first agent and the second inner pouch filled with the second agent were placed in one pressure container, and the inner pouch and Using a dual structure aerosol container having a mechanism for simultaneously discharging the first agent and the second agent, filled with compressed gas between the pressure-resistant containers, the first agent and the second agent of the examples shown in this specification are used. Fill 50 g each into the inner bag in the heavy structure aerosol container, and pressurize compressed nitrogen gas between the inner bag and the pressure container so that the internal pressure applied to the first agent and the second agent is 0.7 MPa (25 ° C.). The filled two-component aerosol type hair dyeing or bleaching composition is adjusted, the first component and the second component are discharged onto a table-shaped brush at a ratio of 1:1, and the hair is cut to a length of 25 cm. Using a test doll (“Cut Mannequin No. 775N” manufactured by Beaulux Co., Ltd.), apply a total of 120 g to the entire head, leave it at 25 ° C. for 15 minutes, wash thoroughly with shampoo, and wipe with a towel. After wiping off the moisture, it was dried with a dryer. This wig was evaluated based on the following evaluation criteria.
<Evaluation Criteria>
◎: Evenly dyed to the ends of the hair 〇: Almost uniformly dyed to the ends of the hair △: Slightly uneven to the ends of the hair, but almost evenly dyed ×: Uneven and uneven stained with
