JPH0714857B2 - Hair cosmetics containing fine powder of animal hair - Google Patents

Description

TECHNICAL FIELD The present invention relates to a hair cosmetic composition containing fine powder obtained by extremely finely crushing animal hair, particularly scale-like fine powder.

[Conventional technology]

Generally, hair is significantly damaged and deteriorated when hair care, brushing, heat with a drier, hair coloring, and beauty treatment with a bleaching agent are repeatedly and frequently applied, and as a result, dryness and dryness, splitting, split hair, broken hair, hair loss are caused. It is well known to cause increase in strength and decrease in strength.

Therefore, for the purpose of protecting and repairing hair against the above hair damage, as a base for hair cosmetics, oil components such as higher alcohols, higher fatty acids, silicone oils, liquid paraffin, ester oils, and natural products are used. Various raw materials extracted from, for example, proteins, polysaccharides, extracted extracts, natural polymers, or simple substances or oligos constituting these, such as amino acids and peptides, are mixed.

[Problems to be solved by the invention]

However, when oil is added, the hair can be protected to some extent from mechanical treatment such as brushing, but it is satisfactory in terms of protection from chemical treatment, prevention of damage, or imparting smoothness and flexibility. It wasn't something.

In addition, the natural product extraction raw material has some effect in preventing damage to hair and protection from chemical or mechanical treatment, but is not always satisfactory in imparting smoothness and flexibility to hair and combability. It didn't go.

Therefore, an object of the present invention is to provide a hair cosmetic composition capable of preventing hair damage, protecting the hair from chemical or mechanical treatment, and at the same time imparting smoothness and flexibility and improving combability. To provide.

[Means for solving problems]

The present inventor achieves the above-mentioned object by incorporating fine powder of animal hair, which is obtained by utilizing the circulating vacuum pulverization technique, into a hair cosmetic composition, which is much finer than the conventional one. I found that I can do it.

Therefore, the present invention provides a hair cosmetic containing a fine powder of animal hair having an average major axis of 30 μm or less and an aspect ratio of 4 or more.

Examples of the hair cosmetic composition of the present invention include shampoo, hair rinse, pre-shampoo type hair treatment agent, hair conditioner, hair treatment lotion, set lotion, Saint jelly, hair blow agent, hair mousse, hair tonic, hair liquid, hair cream, scalp. Treatments, hair color first and second solutions, hair bleaching agents and the like are included.

As used herein, "animal hair" means animal hair, human hair, bird feathers and bird feathers. Examples of animal hair include wool, mink hair, normal goat hair, mohair hair, Tibetan hair, camel hair, cashmere hair, llama hair, alpaca hair, guanaco hair, angora rabbit hair, cow hair, ordinary rabbit hair, horse hair, cats. There is hair, pig hair, etc. Examples of the feathers and feathers of birds include feathers and feathers of moths, ducks, other waterfowls, chickens and the like.

It can be prepared by utilizing a fine powder to be incorporated into the hair cosmetic composition of the present invention, for example, a circulating vacuum grinding technique. The circulation vacuum pulverization is carried out by using a circulation type vacuum pulverization apparatus which is a further improvement of the known vacuum pulverization apparatus (Japanese Patent Publication No. 52-11787) according to the present invention. The above-mentioned known vacuum crushing device is (a) as described in the above publication.
Ground material container for loading raw materials to be treated, (b) crusher equipped with hammer and ridge, (c) ground material container for collecting products, and (d) interlocking transfer interposed therebetween. And (e) a vacuum pump connected to the crushed object container (a) and the crushed container (c). The present inventor has made an improvement to the vacuum type crushing device, so that the hammer and the protruding strip in the crusher (b) are
The rotary blade and the fixed blade were replaced, and the outlet of the crushed material container (c) and the inlet of the crushed material container (a) were connected so that circulating crushing could be performed under vacuum. Circulating vacuum crushing of animal hair using this improved device results in much finer crushing of animal hair than conventional ones.

The circulating vacuum crushing is 2-3 mmHg, preferably 2-10 m
Perform under vacuum of mHg. The circulation is performed 2 to 10 times, preferably 3 times. Before performing the circulating vacuum pulverization, animal hair as a raw material can be degreased with an organic solvent such as diethyl ether, acetone, chloroform or trichloroethane, or degreased and washed with various surfactants. A commercially available product after degreasing / washing treatment can be used as it is.

The product is classified after the circulating vacuum milling process. As the classification method, a method known per se, for example, screening with a sieve, wet classification or dry classification can be used. Dry classifiers such as gravity classifiers, inertial classifiers, especially centrifugal classifiers, are preferably used, and forced vortex centrifugal classifiers are particularly preferred. Fine powder mainly composed of cuticle (hair scalp) forming the outermost layer of animal hair by adopting an appropriate classification means (in this case, for example, forced vortex centrifugal classifier (separation diameter 0.5 to 50 μm) Preferably 0.5 to 30 μm)], or other parts, ie cortex and cortex (medullary pulp)
A fine powder containing a large amount of can be obtained.

The above-mentioned animal hair dyeing, bleaching, UV treatment, electrostatic treatment, water repellent treatment, insect repellent treatment, antiseptic treatment, antifungal treatment, and other surface treatments may be performed before or after the circulating vacuum pulverization treatment or before or after the classification treatment. Although it can be carried out in any case, it is preferably carried out after the classification treatment.

For dyeing, for example, Red No. 3, Red No. 104, Yellow No. 4, Yellow No. 5, Green No. 3, Blue No. 1, Blue No. 2, Red
227, red 230, orange 206, orange 207 yellow 202,
Green 201, green 204, green 205 and other tar dyes, carminic acid, laccaic acid, calsamine, bradylin, crocin, annatto, anthocyanin, safrole yellow, can be dyed in accordance with a conventional method with natural dyes such as samurai yellow it can. Regarding the UV treatment, for example, an ultraviolet absorber such as salicylic acid, para-aminobenzoic acid or urocanic acid can be adsorbed by a conventional method.

By circulating vacuum crushing and classification, the average major axis of 30μ
A fine powder having a particle size of m or less and an aspect ratio of 4 or more is obtained.
The obtained fine powder is mainly composed of scale-like (plate-like) fine powder.

In the present specification, the size of the fine powder is measured as follows. The obtained fine powder was suspended in a dispersion medium such as acetone, placed on an aluminum sample stand, dried, and then gold vapor-deposited as a sample. Take a micrograph. Since the imaging pattern of fine powder is indefinite, the longest diameter is defined as "major axis", and the major axis is measured for at least 50, preferably 100 or more minute powders, and the average value is defined as "average major axis". . Also,
The longest diameter of the above-mentioned "major axis" and the diameter at right angles is defined as "minor axis", and the biaxial average of each fine powder, that is, ("major axis" + "minor axis") x 1/2, is calculated. The average value obtained from the individual biaxial averages in the same manner as above is referred to as "average biaxial average". On the other hand, a sample was prepared from the fine powder in the same manner as above, the sample stage was tilted at about 45 °, and an electron micrograph of the flaky fine powder was taken from the side. The “average thickness” is obtained in the same manner as above. Next, "average biaxial average" / "average thickness"
And calculate this as the "aspect ratio".

The fine powder measured by the above method has an average major axis of 30 μm.
The following is preferably 1 to 20 μm, more preferably 2 to 10 μm,
It has an average biaxial average of 1 to 20 μm, preferably 2 to 10 μm, an average thickness of 5 μm or less, preferably 0.1 to 2 μm, and an aspect ratio of 4 or more, preferably 7 to 100.

When the surface area of fine powder of said measured by the BET method is at 0.1 m ² / g or more, especially from 0.5 to 5 m ² / g.

When the fine powder is observed with an electron microscope, a large number of scale-like powders are visible. Also, in the amino acid composition of the fine powder,
Since the amounts of serine, proline and cystine are high, it is considered that cuticle is the main component. Therefore, the circulating vacuum crushing process is performed to crush individual cuticle units. As described above, since individual cuticle units are crushed, the same crushing is performed at least partially on the animal hair cortex (cortex) and medula (hair pulp). It is considered to be a thing.

The hair cosmetic of the present invention contains 0.001 to 50% by weight of the above-mentioned fine powder based on the total weight of the cosmetic. The preferred blending amount varies depending on the type of hair cosmetic, but generally 0.1 to 2
It is 0% by weight. If the blending amount is less than 0.001% by weight,
The hair damage preventing and protecting effects of the hair cosmetics are not sufficiently exerted, and when the amount is more than 50% by weight, the flexibility and combability are rather deteriorated.

In addition to the above components, the hair cosmetic composition of the present invention can be used as a normal cosmetic composition such as a surfactant, an oil, a moisturizer, an ultraviolet absorber, an alcohol, a chelating agent, a pH adjusting agent, an antiseptic, a thickener, a pigment, and a fragrance. The components used can be blended appropriately.
Of course, these must be in a qualitative and quantitative range that does not impair the effects of the present invention.

〔The invention's effect〕

In the present invention, the fine powder described above is added to a hair cosmetic composition to prevent damage to the hair, protect the hair from chemical and mechanical treatments, and impart smoothness and softness to the hair. It has become possible to obtain cosmetics that improve

Further, since the fine powder has an emulsifying action, it can be prepared without using a surfactant or reducing the amount thereof depending on the type of hair cosmetic composition. Since many surfactants have strong irritation to hair, it is preferable to use as little as possible. Since the hair cosmetic composition of the present invention does not contain a surfactant or contains a small amount, it is not only highly safe for hair in this respect, but also because the fine powder is a keratin protein, it is inherently safe. Is.

Furthermore, the hair cosmetic composition of the present invention is also excellent in fragrance retention.

〔Example〕

Next, the present invention will be described in more detail by way of examples.
The present invention is not limited thereby.

Preparation of compounding ingredients Production example 1: Wool fine powder utilizing circulating vacuum crushing 50 kg of merino type wool that has been degreased and washed by a conventional method and pre-shredded is vacuum-crushed by a vacuum crushing device (Naruwa Kasei: SWW-48
(Type) circulation-type improvement apparatus, the crushed material was loaded into the container, the system was evacuated (5 mmHg), and then the system was operated under conditions of 5.5 kWh and 3000 rpm for 6 hours for crushing. If the same crushing is performed without circulating this device, the required time is 2
Since it was time, this treatment means that the milling treatment was repeated three times on average.

Next, a forced vortex centrifugal classifier (Nissin Engineering: T
C-15N type (separation diameter 20 μm)]
4.5 kg of fine powder having a size of μm or less was obtained. The results of observing the resulting fine powder with a scanning electron microscope (JEOL: JSM-T100 type) are shown in FIGS. 1 and 2.

The fine powder thus obtained is considered to have cuticle as a main component. The reason is as follows.

(1) The amino acid composition of the fine powder was in good agreement with the amino acid composition of the raw wool cuticle (the cuticles contained more serine, cystine and proline than the whole wool).

(2) The shape of the fine powder shown in the electron micrographs (FIGS. 1 and 2) is scale-like, which matches the shape of the cuticle.

(3) The yield of fine powder is almost equal to the weight ratio of cuticle in wool (about 10%).

The fine wool powder had an average major axis of 7.6 μm and an aspect ratio of 10.8.

Production Example 2: Fine powder of moth bird feathers using circulating vacuum pulverization When the feathers of moth birds were treated in the same manner as in Production Example 1, the same fine powder was obtained.

Production Example 3: Mohair fine powder utilizing circulating vacuum grinding When mohair was treated by the same method as in Production Example 1, the same fine powder was obtained.

Production reference example: Wool powder by freeze-grinding Merino wool 10 degreased and washed by the usual method
Soak 0g in 1.0kg of water for 3 hours, then spin-dry.
The water content was 80 g. This was frozen in liquid nitrogen (-196 ° C), and a crusher [Fuji Denki Kogyo: Sample Mill (K II-
1 type)].

The results of observing the thus obtained wool powder with a scanning electron microscope (JEOL: JSM-T100 type) are shown in FIG.

Blending of Hair Cosmetic Example 1 Hair Cream Six types of hair creams having the component compositions shown in Table 2 below were prepared. That is, the phase (A) was stirred at 70 ° C., and the solution obtained by stirring and dissolving the phase (B) at 70 ° C. was added thereto. This was treated with a homomixer and cooled to 30 ° C. to obtain a hair cream.

Next, the resulting 6 types of hair creams have smoothness, flexibility, combability, non-greasiness, flaking (for example, dandruff-like powder on the surface of hair as in the case of blending a large amount of polyvinylpyrrolidone). For the absence of wiping phenomenon) and the lack of oily luster (glare), a female panel of 15 people actually applied 5 g of the sample directly to the hair, and then evaluated it by sensory evaluation.

The evaluation was performed according to the following four-level evaluation.

◎… Remarkably good ○… Good Good △… Normal ×… Poor As is clear from Table 2, the hair creams 1 to 1 of the present invention are
It can be seen that No. 4 is superior in all items as compared with Comparative Hair Creams 1 and 2. In addition, the reason why the non-flaking is highly evaluated in Comparative Cream 1 is
Naturally, since no powders are blended.

Example 2: Hair rinses 11 types of hair rinses having the component compositions shown in Table 3 below were prepared. That is, the quaternary ammonium salt was stirred in purified water under heating to dissolve or disperse it, and the raw material for extracting the natural product and the coloring agent were further added and mixed with stirring to prepare an aqueous (A) phase. On the other hand, cetanol, glycerol monostearate, perfume, and preservative were mixed under heating, fine wool powder was added to the hair rinse of the present invention, and mica or talc was added to the comparative hair rinse, and the mixture was uniformly dispersed by a homomixer. An oily (B) phase was prepared. After maintaining the phase (A) and the phase (B) at 80 ° C., the phase (B) was gradually added to the phase (A) while thoroughly stirring and mixing, and the whole amount was added.
The mixture was stirred and cooled to ℃ to obtain 11 kinds of hair rinses shown in Table 3.

Subsequently, as in Example 1, 15 female panelists actually applied 12 g of the sample directly to the hair, rinsed with warm water, air-dried, and evaluated sensory.

As is clear from Table 3 above, the hair rinse of the present invention is very superior to the comparative hair rinse. Production Example 1
It is not clear why the system containing the circulating vacuum pulverized wool fine powder of No. 1 gives extremely excellent smoothness and flexibility, improves combability, and shows no stickiness, but it is not clear that it is quaternary ammonium salt and wool fine powder. Imagine excellent usability because the powder and the powder electrostatically bind to form a complex, which is electrostatically adsorbed on the hair surface and forms a film on the hair surface. To be done.
