Description

The present invention relates to a hair dye with reduced environmental load used in a hairdressing salon.
In other words, the present invention relates to a hair dye that can reduce the storage space for hair dye in a hairdressing salon and reduce the amount of waste discarded after using the hair dye.

Conventional hair dyeing is a 1: 1 mixture of a hair dye first agent containing an oxidizing dye such as paraphenylenediamine and a hair dye second agent containing an oxidizing agent such as hydrogen peroxide as an active ingredient. The hair dye active ingredient is permeated into the hair and the oxidative dye is oxidatively polymerized inside the hair to dye the hair.

The first hair dye containing an oxidation dye is filled in an aluminum tube that is not oxygen permeable to prevent oxidation of the dye. The inner volume is about 60 to 80 g necessary for hair dyeing per person, and the inner volume of the tube is 65 to 85 cc. The weight of aluminum used for the tube is 7 to 9 g.

Recently, as disclosed in Japanese Patent Laid-Open No. 2001-226238 or Japanese Patent Laid-Open No. 2003-55173, attempts have been made to make the mixing ratio of the first agent and the second agent 1: 3 to 1: 5 or 1: 5 to 1:20. A first hair dye that is made and dyed brightly has been proposed.
JP 2001-226238 A JP 2003-55173 A

There are cases where the hair is dyed by the person himself at home or by a hairdresser at a beauty salon.
When hair is dyed at home, it should be dyed only once a month and to a specific color. On the other hand, in the beauty salon, since the color is selected according to the customer's preference for several tens of people a day, it is necessary to stock the hair dye first agent of over 100 different colors. As a result, there are cases in which the amount of stock is several hundreds, and in a small Japanese beauty salon, it is difficult to store. Furthermore, used tubes are not recycled and are treated as industrial waste, which is expensive and wasteful of resources.

In Japan, hair dyes filled in about 200 million aluminum tubes per year are consumed in beauty salons. Each aluminum tube weighs about 9 g, and the amount of aluminum used is 1800 tons per year, most of which is not recycled and is discarded and wasted resources. The present invention is intended to improve the work environment and workability of a hairdresser, and at the same time to realize a significant reduction in the amount of discarded aluminum containers, and to improve resource problems and environmental problems from the standpoint of a beauty salon. The aim is to reduce the size and weight of the aluminum container of the first hair dye agent by developing a concentrated amount of the first hair dye agent.

Means to solve the problem

By reducing the amount of the first hair dye used per person from one third to one fifth while maintaining and improving the performance of the hair dye, it is possible to reduce the size of the container and reduce the storage space in the beauty salon. Reduce the amount of waste. The amount of hair dye used per person is about 120 g in order to ensure workability and hair coloring on the hair. Conventionally, a total of 120 g of hair dye first agent 60 g and hair dye second agent 60 g are mixed and used. In the present invention, for example, a total of 120 g of the hair dye first agent 20 g and the second agent 100 g is mixed and used. In other words, the mixing ratio of the first agent and the second agent is 1: 1 in the past, but in the present invention, the amount of the hair dye first agent is reduced by mixing at 1: 5, and the container is greatly reduced in size. This enables a reduction in storage space and a reduction in the amount of garbage.

For example, a conventional hair dye container for one person is an aluminum tube with an internal capacity of 60 g, a diameter of 28.5 mm, a length of 156 mm, and a weight of about 9 g. The hair dye first agent of the present invention has an internal volume of 20 g, the aluminum tube has a diameter of 16 mm, a length of 118 mm, and a weight of 3.3 g, and has a volume of about one quarter and a weight of about one third. The storage space at the beauty salon is one-fourth and the garbage is one-third, saving resources and greatly contributing to environmental problems. Furthermore, the workability of the beautician is improved by downsizing the container.

Even if the capacity and weight of the container of the hair dye first agent are reduced, the performance of the hair dye itself is inferior and there is no commercial value. To reduce the size of the container, it is necessary to maintain and improve the performance of the hair dye.
Regarding the mixing ratio of the first hair dye agent and the second hair dye agent, Japanese Patent Application Laid-Open No. 2001-226238 and Japanese Patent Application Laid-Open No. 2003-55173 propose hair colors that are brightly dyed. However, since only ammonia is used as an alkaline agent in a high composition, the scalp is strongly stimulated and the ammonia smell is strong, which causes discomfort to the customer and the work environment is also deteriorated. It is inferior in the irritating odor and irritation of the dyed things.

Effect of the invention

As a result of diligent investigations aimed at reducing the size of the container by eliminating the above-mentioned drawbacks, the present inventor blended a high concentration of conventional ammonia as an alkaline agent of the first hair dye, and at the same time, further blended with ammonium bicarbonate. Thus, the present invention was completed by discovering that the amount of ammonia was reduced, and that there was little irritating odor or irritation, and that it was possible to dye uniformly and brightly with a small amount of one third to one fifth of the conventional amount.

Furthermore, regarding the container filled with this formulation, a small aluminum tube specially processed with an alkali-resistant epoxy phenol resin was used. The aluminum tube was filled with 20 g of the hair dye first agent of the present invention to prepare a hair dye first agent for one person.

While maintaining and improving the quality of hair dyes compared to conventional products, we succeeded in reducing the size of aluminum tubes to one-fourth by volume and one-third by weight. The present invention has been completed by realizing efficient use of resources such as miniaturization of tube.

Best Mode for Carrying Out the Invention

Embodiments of the present invention will be described below.
Since commercially available ammonia is widely used as 28% ammonia water, the concentration will be described in the following description.
Alkaline agents used in the present invention are 28% ammonia water 9-20% (2.5% -5.6% as ammonia) and 2-5% ammonium bicarbonate, as disclosed in JP2001-226238A or JP2003-55173A. Compared with the use of ammonia alone disclosed in JP, the amount of ammonia can be reduced, so the pH can be lowered, the scalp can be stimulated and the irritating odor can be reduced, and the market value is high.

When the blending amount of 28% ammonia water is 9% or less, dyeing is poor, and when it is 20% or more, the scalp is strongly stimulated and the irritating odor is strong, which is not preferable. If ammonium bicarbonate is 2% or less and dyeing is 5% or more, the corrosiveness to the aluminum tube is strong, which is not preferable.

The prescription is preferably a cream emulsified system containing aqueous ammonia and ammonium bicarbonate in order to dissolve a large amount of these dyes and reduce the irritating odor. The formulation is composed of an emulsifier represented by polyoxyethylene alkyl ether as the oil phase, a solid oil component such as higher alcohol represented by cetanol, and a liquid oil component represented by liquid paraffin, etc. Agents, fats and oils, waxes Silicon derivatives, etc. In the aqueous phase, a large amount of dye is added to reduce the irritating odor and dye the hair uniformly and well, together with ammonium bicarbonate instead of ammonia alone.

The hair dye second agent is preferably combined with the composition of the first agent and the oil so that the dye can be oxidatively polymerized with hydrogen peroxide as an oxidizing agent and can be easily mixed with the first agent.
The amount of the hydrogen peroxide solution is described as a commercially available 35% hydrogen peroxide solution.
The mixing ratio of the hair dye first agent and the hair dye second agent is preferably 1: 4 to 1: 8. If it is 1: 4 or less, the effect of miniaturization of the aluminum container is small, and if it is 1: 8 or more, the first agent is too small and workability at the time of toning is poor.
By the way, when the amount used at the time of mixing is 120 g When the mixing ratio of the hair dye first agent and the second agent is 1: 4, the amount used of the hair dye first agent is 24 g, and when it is 1: 8, it is 13 g. Become.
A specific example will be described below.
