Description

The present invention relates to a multi-agent hair treatment agent.

As a hair treatment agent, one containing an amino-modified silicone is known (see JP 2013-40153 A). The hair treatment agent described in this publication is configured as a multi-agent type, and a first agent and a second agent containing an amino-modified silicone are applied in this order and used.

By thus blending the amino-modified silicone with the hair treatment agent, the hair can be conditioned. However, even when the hair is sufficiently conditioned by blending the amino-modified silicone, it may not be possible to realize that the blending effect has been obtained. Specifically, regarding the feeling of thickness when touching the hair (feeling that some kind of substance is coated on the surface of the hair), the feeling becomes superficial and the thickness seems to be clogged inside the hair. If there is a poor feeling, it may not be possible to realize the feeling that such a conditioning effect is obtained.

To do.

The compounding amount of the cationized cellulose in the second agent is preferably 2 parts by mass or more and 40 parts by mass or less based on 100 parts by mass of the amino-modified silicone of the second agent. By setting the amount of the cationized cellulose to be in the above range with respect to the amount of the amino-modified silicone as the second agent as described above, the feeling of flow during washing with water after coating is further improved.

The dosage forms of the first agent and the second agent may be creamy. Since the dosage forms of the first agent and the second agent are creamy in this way, the handling properties when applying the first agent and the second agent to hair are excellent. In addition, by making the dosage form of the first agent and the second agent common to a cream, not only the first agent and the second agent are easily compatible, but also the first agent and the second agent are adapted to the hair. It will be easier.

By thus setting the amino content of the amino-modified silicone within the above range, the above-mentioned conditioning effect can be suitably achieved.

<Arbitrary ingredients>
(Cationized cellulose)
The cationized cellulose improves the oily finger-like discomfort caused by the amino-modified silicone and enhances the feeling of running when washed with water after the application of the multi-component hair treatment agent. Examples of such cationized cellulose include O-[2-hydroxy-3-(trimethylammonio)propyl]hydroxy chloride chloride, which is a polymer of a quaternary ammonium salt obtained by adding glycidyltrimethylammonium chloride to hydroxyethyl cellulose. Examples include ethyl cellulose. Examples of commercially available products of the cationized cellulose include "UCARE Polymer JR-30M" manufactured by Dow Chemical Japan, "Catinal HC-200" manufactured by Toho Chemical Industry, and "Catinal LC-200" manufactured by Toho Chemical Industry. "Catinal LC-100" by Toho Chemical Industry, "POLYQUTA 3000KC" by KCI, and "Poise C-80M" by Kao.

The cationized cellulose preferably has a viscosity of 10,000 mPa·s or more and 40,000 mPa·s or less when made into a 2 mass% aqueous solution, and more preferably 20,000 mPa·s or more and 40,000 mPa·s or less. .. As the viscosity increases, the viscosity of the second agent also tends to increase. Regarding the viscosity of a 2% by mass aqueous solution of cationized cellulose, a value 60 seconds after the start of measurement is adopted using a B-type viscometer under the conditions of 25° C., M4 rotor, and 12 rpm.

The cationization degree of the cationized cellulose (percentage of nitrogen content in the cationized cellulose) is not particularly limited, but is preferably 1.0% or more and 2.0% or less. The nitrogen content is the content of nitrogen atoms contained in the cationized cellulose, and a value based on the nitrogen determination method defined in the standard for quasi drug raw materials is adopted. However, when the nitrogen determination method is not specified in the standard for quasi-drug raw materials, the value based on the Kjeldahl method is adopted.

The compounding amount of the cationized cellulose in the second agent is preferably 2 parts by mass or more and 40 parts by mass or less based on 100 parts by mass of the amino-modified silicone of the second agent. By setting the amount of the cationized cellulose to be in the above range with respect to the amount of the amino-modified silicone as the second agent in this manner, it is suitable for improving the feeling of running when washing with water after the application of the second agent.

(Other optional ingredients)
Other optional components of the second agent include, for example, nonionic surfactants, amphoteric surfactants, lower alcohols, polyhydric alcohols, sugars, ester oils, oils and fats, hydrocarbons, waxes, silicones other than amino-modified silicones, polymers. Examples thereof include compounds, amino acids, animal and plant extracts, microorganism-derived products, inorganic compounds, fragrances, preservatives, sequestering agents, and ultraviolet absorbers.

<pH>
The pH of the second agent at 25°C is preferably 3 or more and 7 or less. When the pH of the second agent exceeds 7, the hair swells when the second agent is applied to the hair, which is not preferable.

<Formulation, viscosity, etc.>
As the dosage form of the second agent, it is preferable that the outer phase is a creamy form having an aqueous phase. In this way, the formulation of the second agent is creamy, which makes it easy to handle the second agent on the hair and makes the second agent easy to adapt to the hair. Further, when both the first agent and the second agent are in a creamy dosage form, the first agent and the second agent are easily compatible with each other. The definition of “the outer phase is an aqueous phase” is the same as in the case of the first agent. In addition, the blending amount of water in the second agent in the case of a cream is, for example, 50% by mass or more and 90% by mass or less.

The viscosity of the second agent is, for example, 1,000 mPa·s or more and 60,000 mPa·s or less when the external phase is a creamy dosage form having an aqueous phase. The viscosity may be measured using a stress control rheometer (“Rheo Stress 6000” manufactured by HAAKE). Viscosity measurement conditions may be, for example, a measurement temperature of 25° C., a cone plate sensor diameter and inclination angle of 35 mm and an inclination angle of 2°, a steady flow curve mode, a waiting time of 1 minute, and a shear rate of 36 s ⁻¹ .

[Uses of multi-agent hair treatment agent]
The multi-component hair treatment agent can be used as a hair care agent or the like. The "hair care agent" is a hair treatment agent used for caring for and treating the hair. Examples of hair care agents include conditioners and treatments. Examples of the treatment include a treatment used after shampoo, a treatment for pre-treatment of perm, a treatment for post-treatment of perm, a treatment for pre-treatment of coloring, a treatment for post-treatment of coloring, and bleaching. The treatment for pre-treatment of bleach and the treatment for post-treatment of bleach are included.

[How to use multi-agent hair treatment agent]
The multi-agent hair treatment agent is used by applying the first agent and then rinsing off the first agent, or by applying the second agent without rinsing off the first agent. The second agent may or may not be washed off after application.

In the case of a two-component type comprising two treatment agents, the multi-agent hair treatment agent is composed of a first agent and a second agent. When the multi-agent type hair treatment agent is composed of three or more treatment agents, it contains one or more other treatment agents in addition to the first agent and the second agent. In this case, the order of using the first agent, the second agent, and the one or more other treating agents may be the order of using the second agent after the first agent. For example, in the case of a three-component hair treatment, another treatment agent may be used before the first agent, between the first agent and the second agent, You may use it later.
