Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention prevents damage to keratinous fibers due to the use of reducing or oxidizing substances,
The present invention relates to a hair treatment composition that can continuously provide a desirable feel.

[0002]

2. Description of the Related Art Permanent wave treatment is to cut cystine bonds of hair keratin and then re-bond them to form waves. Decolorization treatment is performed using melanin with hydrogen peroxide or the like. Is oxidatively decomposed to decolorize hair.

However, the reducing substances or oxidizing substances used in these treatments, in addition to the original purpose of deforming or decolorizing the hair, also wash away the protein component of the hair, so that moisturizing properties, flexibility and smoothness of the hair surface are obtained. It loses its properties and causes dryness / stiffness of hair, split ends, broken hair, and deterioration of luster. It is clear that such a decrease in the physical properties and feel of the hair is not preferable from the viewpoint of beauty as well as the ease of handling the hair during shampooing and styling.

For the purpose of solving these drawbacks, substances having a conditioning effect have been added to treatment agents. Examples of substances having a conditioning effect include silicones, which are known to have a remarkable effect on slipperiness, softness, gloss and the like at the time of dryness, and have been applied to many products.

However, many commonly used silicones, such as dimethylpolysiloxane, amino-modified silicone, polymer silicone, and polyether-modified silicone, all cause squeaky feeling in wet and hair fly in dry, resulting in permanent. It was not possible to sufficiently compensate for the deterioration of the physical properties and feel of the hair caused by the wave and bleaching treatments.

[0006] Therefore, an object of the present invention is to provide a hair treatment composition which contains a reducing substance or an oxidizing substance but prevents damage to keratinous fibers such as hair and does not deteriorate the physical properties and feel of hair. To do.

[0007]

[Means for Solving the Problems] The inventors of the present invention have conducted intensive studies in view of the above circumstances, and as a result, have found that a hair treating agent composition containing a reducing substance or an oxidizing substance contains a specific modified silicone derivative.

10 to 300 ml, preferably 10 to 200 ml (10 to 150 ml in the case of heating type) for each agent and the second agent
Is preferred. After applying the first agent to the hair, preferably 2
After standing for -30 minutes, particularly preferably 2-15 minutes, the usual treatment is carried out. In the case of a heating two-bath type permanent wave agent, the hair is preferably 40 to 160 after the first agent is applied.
Warm to ℃. The heating temperature and time vary depending on the degree of hair damage, the type of reducing agent used, pH, the type of treatment agent, etc., and high-temperature treatment is applied to healthy hair that does not have a perm, hair dye, or bleaching. Is advantageous, but considering the damage to the hair due to heating, it is preferably 40 to 160 ° C.,
Particularly, it is preferably between 40 and 80 ° C. Further, it is effective to cover with a cap and further humidify so that water does not evaporate from the hair during heating. The lower the temperature, the longer the heating time, but for the same reason, the heating time is preferably 30 minutes or less, and 3 minutes to 10 minutes. On the other hand, for chemically treated hair such as perm, hair dye, and bleach, it is desirable to select more buffer treatment conditions.

When used as a cold one-bath type permanent waving agent or a heated one-bath type permanent waving agent, an agent comprising a reducing substance as the component (A) and the component (B) is used. In this case, for example, the permanent treatment is preferably performed by the following method. That is, first, the treatment agent is applied to the hair. Before or after applying the treatment agent, the hair is preferably wrapped around a rod, a curler, a heatable high-die type setting device, etc. to form a desired wave, but when a gentle wave is desired, Using a dryer and brush,
You can make a habit by using the usual blow finishing method. The amount applied varies depending on the length of hair, partial or total perm, and conditions such as heating temperature, but usually 10 to 10 times
It is preferably 300 ml, preferably 10 to 200 ml (10 to 150 ml in the case of the heating type). In the case of a cold one-bath type permanent waving agent, the agent is applied and then left for preferably 2 to 30 minutes, particularly preferably 2 to 15 minutes, and then a usual treatment is carried out. In the case of the heated one-bath permanent wave agent, after applying the agent, the hair is preferably treated with 4 as in the case of the first heated two-bath permanent wave agent.
It is heated to 0 to 160 ° C, particularly preferably 40 to 80 ° C. Similarly, the heating time is preferably 30 minutes or less and 3 minutes to 10 minutes, and it is effective to cover the hair with a cap and to further moisturize it in order to prevent water evaporation from the hair.

On the other hand, when it is used as a decolorizing agent, it can be used in the same manner as a conventional decolorizing agent. For example, a first agent containing an oxidizing substance as the component (A) and citric acid,
Mixing a second agent containing a pH adjusting agent such as phosphoric acid, hydrochloric acid, ammonia, sodium hydroxide, monoethanolamine, triethanolamine, or in the case of one dosage form, as it is or diluted with water, Then, it is applied uniformly on the hair, left for about 10 minutes, then lightly rinsed and shampooed.

The conditioning effect of the composition of the present invention can be further improved by appropriate heating and steaming. For this purpose, a heating device or a steamer generally used in beauty salons may be used.
The hair treatment composition of the present invention can be used not only for the purpose of deforming or decoloring hair but also for the purpose of conditioning effect. In this case, it is preferable to control the concentration of the reducing substance or the oxidizing substance to 2% by weight or less, preferably 1% by weight or less. The hair treatment is preferably carried out under conditions of moderate heating and steaming.

[0027]

EFFECTS OF THE INVENTION The hair treatment composition of the present invention is capable of treating hair with a chemical reaction while preventing damage to the hair and continuously imparting a favorable feeling. Like the conventional silicone-containing hair cosmetics, the present hair treatment composition imparts smoothness, softness and luster to the dry hair, but does not cause undesired hair fly and enables a reasonably moist and cohesive finish. To do. Also,
Unlike conventional silicone-containing hair cosmetics that feel good when dry, but feel wet when wet, in the entire process from application of the agent to wet and dry, the hair feels moisturized, soft and smooth. It can give goodness and suppleness, and this is lasting. Therefore, when applying the agent, rinsing, blowing,
In all the processes such as after drying, the hair can be easily fingered and combed, so it can be operated without burdening the hair, making it easy to put together a hairstyle and giving a desirable texture such as suppleness and luster when finished. .
