Description

Vesicle composition and cosmetics containing the same

The present invention relates to a vesicle composition having a specific cationic surfactant, sterols, and water as constituents and excellent in stability over time, and a cosmetic containing the composition, and in particular, the composition. The present invention relates to a hair cosmetic composition that, when applied to hair, quickly adjusts to the hair, has excellent penetration into the hair, and provides a moist feeling.

Conventionally, sterols such as cholesterol and phytosterol have been studied for incorporation into hair cosmetics as effective components for hair. In particular, cholesterol is originally present in hair as a component related to the moisture retention function of hair, but its content is said to decrease around the age of 10 (see Non-Patent Document 1), and it is moist and dry. It is one of the important ingredients for keeping beautiful hair.
However, sterol derivatives such as cholesterol are generally known as poorly soluble substances that are difficult to dissolve in water and oil (see Patent Document 1), and are particularly stable in lotion-based preparations using water as a medium. It is very difficult to blend in. For this reason, various studies have been conducted on techniques for stably blending these poorly soluble sterol derivatives into cosmetics in aqueous media.
For example, a quaternary alkylammonium salt type cationic surfactant, an amphiphile, a sterol derivative, and water are mixed at a specific blending ratio, whereby a lamellar liquid crystal bilayer vesicle containing an aqueous phase, That is, it is known that vesicles are formed (see Patent Document 2).
As another study, by adding a cationic polymer (see Patent Document 3) and silicone (see Patent Document 4) to a quaternary alkyl ammonium salt type cationic surfactant, a sterol derivative, and a ceramide, It is also known that vesicles are formed.
Furthermore, there is an example in which sterols such as cholesterol are blended using dicocoylethylhydroxyethylmonium methosulphate having an ester structure in a hydrophobic group as a cationic surfactant different from Patent Documents 2 to 4 above ( (See Patent Document 5).

However, all of the techniques of Patent Documents 2 to 4 use a quaternary alkyl ammonium salt type cationic surfactant. If a quaternary alkyl ammonium salt type cationic surfactant is used, sterols are used. In some cases, vesicles were not sufficiently formed, or the vesicles were broken and precipitated over time, and crystallized and precipitated. Furthermore, even when such vesicles are blended into hair cosmetics and applied to hair, there is a problem that it feels familiar with the hair and penetrates into the hair; it is difficult to obtain a sense of penetration and it is difficult to obtain a moist feeling.

Further, according to Patent Document 5, a poorly soluble component such as cholesterol may not be stably blended in a vesicle, so that cholesterol and the like are precipitated over time, and it is difficult to bring about an effective effect on hair. It was.

Accordingly, an object of the present invention is to provide a vesicle composition that can stably blend sterols such as cholesterol, which is an effective ingredient for hair, into an aqueous medium, and that is excellent in stability over time, and a cosmetic comprising the same. . In particular, it is a cosmetic for hair formulated with the composition, and when applied to hair, it is adapted to hair quickly, has excellent penetration into hair, and has a moisturizing effect. It is an object to provide cosmetics.

As a result of intensive studies to solve the above problems, the present inventors have obtained a vesicle composition having excellent temporal stability by combining a cationic surfactant having a specific chemical structure, sterols, and water. The composition can be stably blended in water-based cosmetics, and when blended in hair cosmetics and applied to hair, the cosmetics quickly adapt to the hair surface without staying on the hair surface.

B: Component 6 is heated to 90 ° C.
C: A is added to B and mixed and stirred with a homomixer.
D: C was cooled to room temperature to prepare a sample.

(Evaluation methods)
(1) A hair bundle (hair) is immersed in a sample such as the pyrene-containing vesicle composition prepared by the above table and the above manufacturing method for 12 hours. (2) The hair is taken out from (1), embedded in resin, and crossed by a microtome. Surface section preparation (3) The section of the hair cross section of (2) was observed with a fluorescence microscope (observation conditions of the fluorescence microscope: excitation filter: 330-385 nm, fluorescence filter: 420 nm, exposure time: 0.20 S). With respect to the obtained vesicle composition, the penetrability of pyrene, which is a fluorescent marker, into the hair was evaluated to evaluate the permeability of the vesicle composition (cholesterol) into the hair.

The result (photograph) observed with the fluorescence microscope of (3) is shown in FIG.
3, FIG. 3-1, FIG. 3-2, FIG. 3-3, and FIG. 3-4 show the product 5 of the present invention, comparative product 2 (fluorescent marker; no pyrene added), and comparative product 3 It is sectional drawing of the hair immersed in the sample of the comparative product 4. FIG.
In the photograph of FIG. 3, the portion that is shining blue (the portion that appears white in the black-and-white drawing) indicates that pyrene, which is a fluorescent marker, is present.
From the photograph of FIG. 3, FIG. 3-2 immersed in the comparative product 2 containing no pyrene hardly shows anything (the shape of the hair cross section is not known), and the comparative product is simply added to the hydrocarbon oil. Fig. 3-3 immersed in 3 only looks blue (approximally white in black and white drawings) so that the state of the hair cross-section can be clearly understood, and instead of component (A), it is a quaternary alkylammonium salt type cationic compound having two long chains 3-4 immersed in comparative product 4 using a surfactant is slightly different from the one immersed in comparative product 3, although the bluish whiteness (whiteness in black and white drawings) is stronger and the state of the hair cross section can be understood. You can see that there is no.
On the other hand, FIG. 3-1, immersed in the vesicle composition of the product 5 of the present invention, is clearly pale in color as a whole hair cross section (white in the black-and-white drawing) compared to the one immersed in the above comparative test example. It is shining well.
That is, it can be seen that the vesicle composition of the product 5 of the present invention prepared using the component (A) has very high permeability into the hair.
This is because the component (A) has a microscopic polarity due to the ester bond in the lipophilic group, and thus the membrane fluidity of the vesicle membrane (deformability of the vesicle membrane) is excellent, It is thought that it penetrated easily and therefore high permeability was exhibited.

(Experimental conditions and results regarding water retention capacity)
Further, the product 5 of the present invention prepared above was permeated into the hair, and the binding water ratio in the hair was quantified. The result is shown in FIG. This effect relates to the effect of imparting a moist feeling to the hair of a hair cosmetic (hair lotion). For the measurement, a near-infrared spectrophotometer “Spectrum 400” (manufactured by Perkin Elmer) was used, and a hair bundle (about 5 g) made of the same human hair was used as a test sample. Specifically, it is as follows.
The product 5 of the present invention was applied to a hair bundle and dried well to obtain a hair sample. As a comparative control product, purified water was applied to a hair bundle (about 5 g) of the same human hair, and a well-dried reference hair sample was obtained. Near-infrared spectroscopic measurement was performed in the range of 5350 cm ⁻¹ to 4950 cm ⁻¹ , and the peak area of the obtained spectrum was applied to the following formula 1 to obtain the bound water ratio in the hair.
Formula 1
Bonded water ratio (%) = {peak area 1 / (peak area 1 + peak area 2)} × 100
Peak area 1 (5150 cm ⁻¹ to 4950 cm ⁻¹ ): Strong bound water (means that moisture transpiration hardly occurs from hair)
Peak area 2 (5350 cm ⁻¹ to 5150 cm ⁻¹ ): Weak bound water (means that water is likely to evaporate from the hair)

From the results shown in FIG. 4, it is understood that the binding water ratio in the hair of the hair sample applied with the product 5 of the present invention is significantly increased compared to the reference hair sample applied with purified water. it can. This indicates that the moisture retention ability of the hair has been improved by applying the product 5 of the present invention, that is, it can be understood that this effect is due to the moist feeling imparted to the hair.

Example 4
(Stability evaluation of vesicle composition over time)
Vesicle sample 1 obtained by dispersing 1 part by mass of dipalmitoylethylhydroxyethylmonium methosulphate (DEQ) in 99 parts by mass of water (ie, DEQ / CL = 10/0 (molar ratio)), DEQ, and cholesterol ( CL) and a vesicle sample 2 obtained by dispersing 1 part by mass in 99 parts by mass of water (that is, DEQ / CL = 7/3 (molar ratio)), A vesicle sample 3 obtained by dispersing 1 part by mass of distearyldimethylammonium chloride (DSAC) in 99 parts by mass of water (that is, DSAC / CL = 10/0 (molar ratio)), DSAC, and CL were added in moles. Vesicle sample 4 (ie, DSAC / CL = 7/3 (molar ratio) obtained by premixing at a ratio of 7/3 and dispersing 1 part by weight in 99 parts by weight of water. )) Was prepared, respectively. The reagents used for preparing each sample are the same as the reagents used in Example 1, respectively.

In preparing each sample, each component was dissolved in tetrahydrofuran (THF), then the solvent (THF) was removed with a rotary evaporator, heated to 80 ° C., purified water was poured, and a probe-type ultrasonic irradiator “VCX130PB” (Manufactured by SONIC & MATERIALS) was prepared by ultrasonic irradiation for 30 minutes. The solid content concentration of each obtained sample was unified to 1% by mass. The obtained vesicle dispersion was treated with an extruder a plurality of times to make the average particle size uniform, and the change in the average particle size over time was observed.
In addition, each sample was observed with a polarizing microscope, and at the initial stage, a Martelose cross image was confirmed, that is, it was confirmed that a vesicle was formed.

The results are shown in FIGS. 5 and 6, respectively.
From the results shown in FIG. 5, in the vesicle composition containing dipalmitoylethylhydroxyethylmonium methosulphate (DEQ) which is an example of the component (A) according to the present invention, the sample 2 to which cholesterol was added added cholesterol. It can be understood that the diameter of the vesicle particles does not vary and the stability over time is excellent as compared with the sample 1 that is not.
On the other hand, from the results shown in FIG. 6, in the vesicle composition containing distearyldimethylammonium chloride (DSAC) having a long-chain alkyl group not containing an ester bond, the time-dependent stability of Sample 4 is significantly reduced by the addition of cholesterol. I can understand.

The vesicle sample 1 prepared above (ie, DEQ / CL = 10/0 (molar ratio)) and the vesicle sample 2 (ie, DEQ / CL = 7/3 (molar ratio)) are differentially scanned. Since the calorific value was measured, the result is shown in FIG. In addition, "DSC7020" (SII company) was used for the measurement, the measurement was performed in the range of 30 ° C to 110 ° C with aluminum oxide powder as the reference substance and the temperature raising condition of 1 ° C / min.
From the DSC curve shown in FIG. 7, the endothermic peak (the part surrounded by a circle in the figure) accompanying the gel-liquid crystal transition of DEQ observed in the vesicle sample 1 from 35 ° C. to 45 ° C. disappears in the vesicle sample 2. This indicates that DEQ and CL are compatible at the molecular level, and a thermally stable gel-liquid crystal intermediate is formed.
