Description

The present invention is a solid treatment to be applied to the hair, especially a solid treatment that utilizes a frame kneading manufacturing method in which a solvent such as water or alcohol is included during production, various components are uniformly dissolved, and after cooling and solidification, the solvent is volatilized by aging. Regarding.

In recent years, plastic waste has become a major cause of marine pollution problems, and the reduction of plastic waste is recommended from the perspective of the SDGs. For example, plastic waste is reduced by changing plastic packaging to paper, and by solidifying liquid products, paper packaging can be selected. For hair care products, the solidification of shampoos, conditioners, treatments, etc. will expand the options for packaging containers, improve environmental problems, and reduce transportation work and storage space. I can say.
However, in order to solidify hair care products, there is a problem in performance such as usability in that a large amount of oils and conditioning components that can impart elasticity and flexibility to hair cannot be blended.

In addition, the aged solid treatment according to the present invention is said to have a moderate hardness, excessive melting reduction, and no stickiness during use because solvents such as alcohol volatilize through the aging process, and the odor peculiar to alcohol does not easily remain. have advantages.

Preferred embodiments of the present invention are described below.
(A) Hydroxystearic acid Hydroxystearic acid is preferably used as a solidifying agent in the present invention.
When hydroxystearic acid is blended alone or when PEG-60 hydrogenated castor oil, which is a nonionic surfactant, is blended alone, the solidification effect is low, but by mixing both, uniformity and high hardness are obtained. A hardened product is obtained.
On the premise of mixing with PEG-60 hydrogenated castor oil, etc., which is a nonionic surfactant, hydroxystearic acid tends to increase hardness according to the blending amount, and the blending amount of hydroxystearic acid is 5% in the composition. If it is less than 15% by mass, the hardness is insufficient.
Therefore, it is preferable that the amount of hydroxystearic acid charged (the amount in the unripened solid treatment) is 5 to 15%.

(B) Polyoxyethylene hydrogenated castor oil The polyoxyethylene hydrogenated castor oil used in the present invention is preferably selected from the group consisting of PEG-30 hydrogenated castor oil and PEG-60 hydrogenated castor oil.
By mixing with hydroxystearic acid, a uniform solidified product with high hardness can be obtained.

(C) Higher Alcohol As the (C) higher alcohol used in the present invention, specifically, cetanol, stearyl alcohol and behenyl alcohol are preferably used. These components may be used singly or in combination of two or more.
From the viewpoint of high-temperature stability (50° C./4 weeks), it is preferably composed of a higher alcohol having 18 or more carbon atoms, and the charged amount (amount in the unaged solid treatment) is 5 to 15% by mass, more preferably It is preferable to blend 5 to 10% by mass.

(D) Water, (E) Alcohol In the present invention, water, ethanol and the like are preferably used as the volatile solvent for homogeneous dissolution of the formulation including the base.
In the present invention, the amount of the volatile solvent charged (the amount in the unaged solid treatment) is preferably 15 to 47% by mass, and can be reduced to about 20% by mass or less by going through the aging process. .

(F) Cationic polymer A cationic polymer can be used in the present invention.
In particular, it is useful to incorporate cationic polymers in conditioning compositions such as hair treatments and conditioners.
Cationic polymers include polyquaternium-7 (diallyldimethylammonium chloride + acrylic acid amide), polyquaternium-10 (cationized cellulose), polyquaternium-39 (diallyldimethylammonium chloride + acrylic acid amide + acrylic acid), cationized guar gum ( Guar hydroxypropyltrimonium chloride), behentrimonium chloride and the like are preferably used, but polyquaternium-10 is particularly preferable from the viewpoint of feeling in use and hardness.

Examples of nonionic surfactants include, but are not limited to, glyceryl stearate, which is a glycerin fatty acid ester.

(H) Silicone oil In the present invention, silicone oil can be used as a conditioning component.
Examples of the silicone oil include, but are not particularly limited to, highly polymerized dimethylpolysiloxane.

<Manufacturing method of solid treatment>
In the production of the solid treatment containing the above components (A) to (E), the above components (A) to (E) are charged in a production kettle, heated and uniformly dissolved, poured into a frame, and cooled to solidify.
When other ingredients such as a humectant are blended, they are heated together with the above components (A) to (E) to uniformly dissolve, and then cooled and solidified using, for example, a cooling and solidifying frame.
After that, it is cut and molded into a predetermined shape if necessary. A so-called individual molding, in which the frame itself is formed into a shape, may be used.

Since the solid treatment of the present invention uses a relatively large amount of solvent (ethyl alcohol, water) in the preparation ingredients, the solvent is removed by volatilization in a constant temperature and humidity room for about 1 week to 3 months after cooling and solidification. It is preferable to take an aging step. The aged solid treatment according to the present invention has the advantages of higher hardness, better shapeability, and less disintegration when in contact with water, by subjecting the unripened solid treatment to aging.

First, the present inventors used hydroxystearic acid and hydrogenated castor oil to examine the solidifying action of both.
Table 1 shows the results.

As is clear from Table 1, in Test Examples 1-4, 1-5, and 1-6, in which hydroxystearic acid and hydrogenated castor oil were used alone, the hardness was low, the solidification action was insufficient, and the appearance was unsuitable. there were.
On the other hand, when both hydroxystearic acid and hydrogenated castor oil are mixed as in Test Examples 1-7 and 1-8, a uniform and sufficiently hard solid treatment is obtained, and the hardness after aging is also sufficient. It was something.

Next, the present inventors examined the blending amount of hydroxystearic acid.
Table 2 shows the results.

As can be seen from Table 2, the hardness of the unaged product tends to increase according to the blending amount of hydroxystearic acid. When the amount of hydroxystearic acid is less than 5.0% by mass, the hardness is insufficient, and when it exceeds 15.0% by mass, there is a problem of being too hard to dissolve. From the above, from the viewpoint of hardness and usability (ease of dissolving), the blending amount of hydroxystearic acid is preferably 5.0 to 15.0% by mass.

Next, the present inventors examined the compounding amount of hydrogenated castor oil.
Table 3 shows the results.

As can be seen from Table 3, unlike hydroxystearic acid, hydrogenated castor oil did not tend to significantly increase the hardness of unaged products depending on the blending amount.

Next, the present inventors conducted a comparative study on the effects of higher alcohols and higher fatty acids on hardness.
Table 4 shows the results.

As can be seen from Table 4, the unaged products obtained by substituting higher fatty acids for various higher alcohols had low hardness and uneven hardness. From the above, it is preferable to select a higher alcohol from the viewpoint of hardness and uniformity.

Next, the present inventors compared and examined the long-term high-temperature stability (50° C./4 weeks) of aged products containing various higher alcohols.
Table 5 shows the results.

As can be seen from Table 5, Test Examples 3-1 and 5-1 using cetanol were solidified at the time of preparation, but softened and melted under high temperature conditions of 50°C for 4 weeks, indicating poor stability. Ta. On the other hand, Test Examples 5-2 and 5-3 using stearyl alcohol and behenyl alcohol were excellent in hardness at the time of preparation and high-temperature stability over time (50° C./4 weeks) of aged products.
From the above, it is necessary to select a higher alcohol having 18 or more carbon atoms in order to solidify at the time of preparation and ensure high-temperature stability (50° C./4 weeks).

Next, based on the results shown in Table 5, the inventors examined the influence of the blending amount of the higher alcohol having 18 or more carbon atoms on the high-temperature stability.
Table 6 shows the results.

As can be seen from Table 6, in order to solidify at the time of preparation and have excellent high-temperature stability (50°C / 4 weeks), a higher alcohol with 18 or more carbon atoms is required as the amount of preparation (amount in the unaged solid treatment). It is preferably blended in an amount of 5 to 15% by mass, more preferably 5 to 10% by mass.

In the present invention, solvents such as water and alcohol can be blended in the unaged solid treatment, and due to the presence of hydroxystearic acid, nonionic surfactants, higher alcohols, etc., and through the aging process, It was possible to obtain an aged solid treatment containing conditioning ingredients and having good uniformity and hardness.

Although formulation examples of the solid treatment of the present invention are shown in Table 7, the technical scope of the present invention is not limited by these. All of the resulting solid treatments had moderate hardness and were excellent in uniformity and stability.
In addition, a large amount of conditioning ingredients (silicone, etc.), which could not be blended in conventional solid treatment manufacturing methods, could be blended.
