Description

  TECHNICAL FIELD The present invention relates to a non-aqueous spray hair cosmetic composition and an aerosol product formulated with a UV absorber.

It is a common practice to incorporate UV absorbers into skin cosmetics such as sunscreen creams and lipsticks to avoid the adverse effects of UV light. Moreover, not only for skin but also for suppressing the influence of ultraviolet light on hair, an ultraviolet absorber is blended in the cosmetic for hair.
For example, in each of Patent Document 1, Patent Document 2, and Patent Document 3, cosmetic compositions in which ultraviolet light absorbers are blended are proposed.

Unexamined-Japanese-Patent No. 07-330564 Japanese Patent Application Publication No. 09-175974 Japanese Patent Application Publication No. 11-514670

  Here, the cosmetic described in Patent Document 1, Patent Document 2 and Patent Document 3 is a general cosmetic which is not specialized for hair use, and specifically, an oil-in-water emulsion or oil An example is proposed in which water accounts for more than half of the agent, such as a water-in-water emulsion.

However, in these examples, more than half of the agent is composed of water, and the amount of water is large, so radicals tend to occur.
Therefore, when it is used for hair, the presence of moisture, even if it is possible to suppress the damage to the hair due to ultraviolet rays (the influence on proteins, the outflow of lipids, fading, etc.) by blending the ultraviolet absorber, As a result, active oxygen is likely to be generated, and the hair is likely to swell due to water, so that the active oxygen is likely to move and damage to the hair may be increased.

  In addition, when it is used as a hair spray, it may adhere to not only the hair but also the clothes worn, so it is required that the color of the preparation be transparent. However, many UV absorbers may become yellow when dissolved in a solvent, or may become more yellowish by mixing multiple types of UV absorbers. In particular, when the color of the clothes worn is white, the adhesion of the yellow agent is noticeable.

Furthermore, when the agent attached to clothes is washed using a general alkaline detergent, there is a possibility that the yellowish taste may be increased by reacting with the alkaline detergent.
The present invention has been made in view of the above-mentioned point, and a subject of the present invention is a non-aqueous spray hair cosmetic and aerosol product capable of suppressing yellowishness while suppressing damage to hair. To provide.

As a result of intensive studies conducted by the present inventors, yellowing can be suppressed by selecting a specific ultraviolet absorber and making it non-aqueous in spray hair cosmetic or aerosol products containing the ultraviolet absorber. The present invention has been completed.
That is, the sprayable hair cosmetic composition according to the present invention is non-aqueous, and contains a stock solution containing octocrylene, t-butylmethoxydibenzoylmethane, and ethanol.

  Here, "non-aqueous" means that water is not blended, or if the water is blended, the blending amount of water in the stock solution in the spray container is 5% by weight or less I assume.

Moreover, it is preferable that the compounding quantity of (C) ethanol with respect to a undiluted | stock solution is 40 weight%-70 weight%, for example for non-aqueous hair cosmetics for sprays.
Also, in the non-aqueous spray hair cosmetic composition, for example, the stock solution does not contain diethylhexyl sycynylidene malonate, or even if it is blended, the compounding amount of diethylhexyl syringyl malonate with respect to the stock solution Is preferably 1% by weight or less. As described above, by limiting the compounding amount of diethylhexylsyringyl malonate to the stock solution, it is possible to suppress that the non-aqueous spray hair cosmetic is colored in yellow due to the action of the alkaline detergent.
Further, in the non-aqueous hair cosmetic for spray, for example, it is preferable that no surfactant is blended in the stock solution, or that the blending amount of the surfactant is 2% by weight or less of the whole stock solution. In this case, it is possible to prevent the styling from being broken and to suppress the deterioration of the touch.

In addition, it is preferable that, for example, the non-aqueous spray hair cosmetic composition be used in a state in which (D) a propellant is blended. In this case, by filling the undiluted solution with the propellant in a pressure-resistant container and injecting it, it becomes possible to easily apply to the hair without soiling the hand.
Moreover, it is preferable that high polymerization dimethicone is further mix | blended with the undiluted | stock solution, for example for non-aqueous hair cosmetics for sprays. In this case, when the undiluted solution is filled with the propellant into the pressure-resistant container and used by spraying, it is possible to suppress the retention degree of the jetted material to be visually observed.
Moreover, as for the hair cosmetics for non-aqueous spray, it is preferable that the weight ratio (undiluted | stock solution / propellant) of a undiluted | stock solution and a propellant is the range of 10/90-50/50, for example. In this case, it is possible to suppress the retention degree of the jetted material visually observed when being jetted from the pressure container.

In the non-aqueous hair cosmetic for spray, for example, the stock solution does not contain the ultraviolet light scattering agent which is an inorganic compound, or the blending amount of the ultraviolet light scattering agent which is an inorganic compound is 0. It is preferable that it is 5 weight% or less. In this case, it is possible to suppress the deterioration of the feel due to the ultraviolet light scattering agent and the tendency of the coated portion to be white, and to suppress the retention degree of the jetted material visually observed when being jetted from the pressure container.
In addition, non-aqueous spray hair cosmetics are preferably used for, for example, styled hair. In this case, since the water is not blended or the blending amount thereof is small, even if it is applied to the styled hair, it is possible to provide an ultraviolet protection function without breaking the style. .

  In addition, the aerosol product according to the present invention includes, for example, any pressure-resistant container filled with the non-aqueous spray hair cosmetic composition and (D) propellant described above.

  According to the non-aqueous spray hair cosmetic or aerosol product according to the present invention, it is possible to suppress yellowishness while suppressing damage to the hair.

The non-aqueous spray hair cosmetic composition and the aerosol product will be specifically described by way of examples, but these descriptions do not limit the invention.
The non-aqueous spray hair cosmetic composition of the present embodiment is a non-aqueous, non-aqueous stock solution containing (A component) octocrylene, (B component) t-butylmethoxydibenzoylmethane, and (C component) ethanol. Contains.
The non-aqueous spray hair cosmetic composition may be used by filling in a spray container. In addition, the non-aqueous spray hair cosmetic composition may be used together with the (D) propellant in a pressure container to be used as an aerosol product.
In addition, the object which contains (A component), (B component), and (C component), and does not contain (D component) may be called a "stock solution."
Each component will be described in detail below.

(A component)
The A component is octocrylene. Oktocrylene is an ultraviolet absorber of a brown clear liquid at normal temperature.
The compounding amount of the component A in the stock solution is preferably 1% by weight or more and 20% by weight or less, and more preferably 3% by weight or more and 10% by weight or less. By setting the content to 20% by weight or less, stickiness of the applied portion can be suppressed.
The component A may be blended more than the component B.

(B component)
Component B is t-butylmethoxydibenzoylmethane. t-Butylmethoxydibenzoylmethane is a transparent UV absorber which is solid at normal temperature and which is slightly yellow when viewed in solution in ethanol.
The blending amount of the component B in the stock solution is preferably 0.1 wt% or more and 20 wt% or less, and more preferably 0.5 wt% or more and 10 wt% or less.
The t-butyl methoxydibenzoylmethane of component B is poor in light stability, for example, it absorbs ultraviolet light and then inactivates, but the light stability is improved by using it with octocrylene of component A.
In addition, there are many combinations in which the yellowishness is increased by mixing as an ultraviolet absorber, but when the A component and the B component are mixed in particular, the yellowishness can be suppressed to be transparent. become.

(C ingredient)
The C component is ethanol.
Ethanol as component C has good solubility of component A and component B.
Since ethanol has volatility, even when it adheres to the hair, it becomes possible to suppress the stickiness of the hair.
The lower limit of the blending amount of the component C in the stock solution is preferably 40% by weight, and the lower limit is more preferably 50% by weight. The upper limit of the amount of the component C in the stock solution is preferably 70% by weight, and more preferably 60% by weight.

(D ingredient (arbitrary ingredient))
The propellant (D) may be loaded into a pressure container together with the stock solution and used as an aerosol product.
The propellant at this time may be a known one, and one or two or more selected from liquefied petroleum gas (LPG); compressed gas such as nitrogen gas and carbon dioxide gas; hydrocarbon compound such as isopentane;
The liquefied petroleum gas (LPG) is not particularly limited, and may be, for example, propane and n-butane (normal butane), propane and i-butane (isobutane), or propane, n-butane and i-butane.
When carbon dioxide is blended, it is possible to promote blood circulation in the scalp.

  Propellants as component D tend to get out of the container earlier than liquefied petroleum gas (LPG), and hydrocarbon compounds have difficulty in securing the pressure required for injection compared to other examples. Preferably, a large amount of liquefied petroleum gas (LPG) is blended.

  The weight ratio of the stock solution to the propellant of component D (the weight ratio of the stock solution / propellant) is 10/100 of the stock solution / propellant from the viewpoint of suppressing the retention of the jetted material visually observed when being jetted from the pressure container. It is preferable to mix | blend by the weight ratio of 90-50 / 50, and it is further more preferable to be mix | blended by the weight ratio of 20 / 80-40 / 60.

(Optional ingredient to be blended into the stock solution)
The optional components to be blended into the stock solution are not particularly limited, but, for example, surfactants (cationic surfactants, anionic surfactants, amphoteric surfactants, nonionic surfactants), polyhydric alcohols, saccharides, ester oils, Oils and fats, fatty acids, hydrocarbons, waxes, silicones, polymer compounds, amino acids, animal and plant extracts, products derived from microorganisms, inorganic compounds, fragrances, preservatives, sequestering agents, UV scattering agents that are inorganic compounds, etc. may be mentioned. .

  However, the undiluted solution does not contain a surfactant, or it does not contain a surfactant, because the stickiness occurs by absorbing moisture, and there is a possibility that the styling may be broken and the touch can not be made good. Even if it is mixed, it is preferably 2% by weight or less of the whole stock solution, and even if it is blended, it is more preferable that it is 1% by weight or less of the whole stock solution. In addition, when mix | blending surfactant, it is preferable to mix | blend nonionic surfactant as surfactant which is not ionic.

  Moreover, it is preferable that highly polymerized dimethicone is mix | blended with the undiluted | stock solution as silicone. Here, high polymerization means that the polymerization degree is 650 or more. When highly polymerized dimethicone is blended, it is possible to improve the feel (slip feeling) of the hair and to increase the gloss of the hair. Furthermore, when the undiluted solution is filled with a propellant into a pressure-resistant container and used by being injected, it is possible to suppress the retention degree of the jetted material to be visually observed. This is considered to be due to the fact that the residence time of the propellant can be shortened by increasing the average particle size of the propellant by blending the highly polymerized dimethicone. Although the compounding quantity in the undiluted | stock solution of highly polymerized dimethicone is not specifically limited, For example, 2 weight% or less may be sufficient, and it is preferable that it is 1 weight% or less. The highly polymerized dimethicone preferably has a viscosity of 2000 mPa · s or more and 10000 Pa · s or less when it is contained in decamethylcyclopentasiloxane (cyclopentasiloxane) in a proportion of 15% by mass (in addition, the above viscosity Means a value after 60 seconds from the start of measurement when using a B-type viscometer and measuring using a rotor No. 4 as a rotor rotational speed of 60 rpm at 25 ° C.).

  Moreover, volatile silicones, such as cyclopentasiloxane, may be mix | blended with the undiluted | stock solution. Such volatile silicone can function as a solvent for highly polymerized dimethicone, and therefore, when used together with highly polymerized dimethicone, it becomes possible to enhance its solubility. In addition, as such volatile silicone, for example, linear dimethyl silicone such as octamethyltrisiloxane, decamethyltetrasiloxane, methylpolysiloxane (having a low viscosity of about 0.65 to 5 cp); octamethyl Cyclic dimethyl silicones such as cyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane and the like. Although the compounding quantity in the undiluted | stock solution of volatile silicone is not specifically limited, For example, it can be 30 weight% or more and 40 weight% or less.

  In addition, it is preferable that the ultraviolet scattering agent which is an inorganic type compound is not mix | blended with a undiluted | stock solution, or the compounding quantity of the ultraviolet scattering agent which is an inorganic type compound is 0.5 weight% or less of the whole undiluted | stock solution. Examples of such ultraviolet light scattering agents which are inorganic compounds include zinc oxide and titanium oxide. As described above, by not blending or reducing the blending amount of the ultraviolet light scattering agent which is an inorganic compound, it is possible to suppress the tendency of the deterioration of the touch and the whitening of the application site caused by the ultraviolet light scattering agent, and It is possible to suppress the retention degree of the jetted material visually observed at the time of

Further, it is preferable that the stock solution does not contain an ultraviolet absorber other than (A component) octocrylene or (B component) t-butyl methoxydibenzoylmethane, and even if it is blended, it is 30% of the whole stock solution. It is preferable that it is weight% or less. Examples of such UV absorbers include dimethyl PABA ethyl hexyl, diethylhexyl syringyl malonate, trimethoxybenzylidene pentanedione and the like. By not blending such an ultraviolet absorber or reducing the blending amount, it is possible to suppress the yellowishness of the spray hair cosmetic.
Among them, diethylhexylsyringyl malonate is a brown transparent UV absorber at normal temperature, but exhibits strong yellow color by the action of alkaline detergent. Therefore, 1 weight of diethylhexyl syringylidene malonate to the stock solution is 1 weight with respect to the stock solution of the non-aqueous spray hair cosmetic composition, or even if it is mixed, about diethylhexyl syringylidene malonate. It is preferable to make it% or less. As described above, by limiting the compounding amount of diethylhexylsyringyl malonate to the stock solution, it is possible to suppress that the hair cosmetic for spray is colored in yellow due to the action of the alkaline detergent.

(Non-aqueous)
In the non-aqueous spray hair cosmetic composition, water is not blended, or when water is blended, the blending amount of water in the stock solution in the spray container is 5% by weight or less.
In addition, even when water is blended, the blending amount of water to the stock solution is preferably 3% by weight or less, more preferably 1% by weight or less, and 0.5% by weight or less. It is further preferred that

  As described above, the non-aqueous spray hair cosmetic composition does not contain water or is contained in a small amount, so the generation of active oxygen is suppressed by the presence of water, and the hair swells. Since it is difficult to do so, the movement of active oxygen is also suppressed, and it is considered that it is possible to minimize the damage given to the hair (effect on proteins, outflow of lipids, fading, etc.). In addition, since water is not blended or the blending amount is small, when it is used for the hair after styling, the hair is difficult to wet and the styling is unlikely to be broken.

(Formulation of undiluted solution)
The formulation of the non-aqueous spray hair cosmetic composition of the present embodiment is preferably in the form of a liquid when it is used as an aerosol product by filling a pressure container together with a propellant, and it is not a cream but not a gel. Is preferred.
Here, when the preparation type is adjusted to liquid, the viscosity of the stock solution after 60 seconds measured at 25 ° C. using a B-type viscometer is, for example, 100 mPa · s or less.

(SPF (Sun Protection Factor))
The SPF of the non-aqueous spray hair cosmetic composition of the present embodiment is preferably 30 or more, and more preferably 50 or more.
In addition, said SPF is measured based on (1) ISO24444 Cosmetics-Sun protection methods-In vivo determination of the sun protection factor, (2) the decimal point of SPF calculated as an arithmetic mean of SPFi obtained by this measurement It is expressed as an integer with rounded down.

(Spray container)
The non-aqueous spray hair cosmetic composition of the present embodiment can be used by being placed in a spray container. By being put in the spray container in this way, it becomes possible to easily apply to the hair without staining the hands (without washing the hands).
The non-aqueous spray hair cosmetic may be filled in a pressure container together with the (D) propellant and used as an aerosol product. Here, the pressure-resistant container is not particularly limited, and may be made of metal such as aluminum, aluminum alloy, tinplate, or steel. Furthermore, the surface of the pressure container made of metal may be plated. These pressure-resistant containers may be provided with a resin layer on the inner surface or may not be provided with the resin layer, or a non-aqueous spray hair cosmetic and (D) It may or may not have a bladder filled with a propellant.

  The non-aqueous spray hair cosmetic composition may be used in the container of the mist pump without using the (D) propellant. That is, when the container of the mist pump is operated by the user, the inside of the container may be pressurized, and the non-aqueous spray hair cosmetic may be ejected by the pressurization. As a container of such a mist pump, the container for general misting is mentioned, for example.

(Use)
The application of the non-aqueous spray hair cosmetic is not particularly limited as long as it is used for protecting the hair from ultraviolet light.
For example, it may be used as a hair styling agent, or it may be used on a styled hair. Non-aqueous spray hair cosmetics contain no or only a small amount of water, so even if they are sprayed onto the hair in the styled state, the hair does not get wet easily and UV protection does not break its style It becomes possible to give a function. Moreover, although ethanol is mix | blended with the hair cosmetic for non-aqueous systems, since ethanol is volatile, it is hard to get wet and it is hard to destroy styling.

  EXAMPLES The present invention will be more specifically described by way of the following examples. However, the present invention is not limited to the following examples unless it deviates from the spirit of the present invention.

Example 1 and Comparative Examples A to D

In Example 1 and Comparative Examples A to D, the pressure container was filled so that the amount of the propellant was 85 parts by weight with respect to 15 parts by weight of the stock solution. Here, LPG having a pressure of 0.15 MPa at 20 ° C. was used as a propellant.
In addition, as a pressure-resistant container of Example 1, one having a valve of S13 series (stem hole diameter diameter 0.3 mm, housing lateral hole diameter 0.6 mm, housing pilot hole diameter 0.5 mm) manufactured by Mitani Valve Co., Ltd. was used. Moreover, the button used the thing of the mechanical brake up type (nozzle hole diameter diameter 0.43 mm) made from Mitani Valve.

The evaluation methods and criteria are shown below. The evaluation was conducted by three panelists.
(1) Color of stock solution The yellowness of the stock solution was visually evaluated. Evaluation criteria are as follows.
◎: Colorless (3 out of 3 people answered that it is colorless)
○: Slightly yellow (1 out of 3 people say yellow)
:: somewhat yellow (2 out of 3 people say yellow)
×: Yellow (3 out of 3 people say yellow)
Cloudiness: The color when sprayed on white cloth (2) Sprayed on white cloth The color immediately after spraying the white cloth for about 2 seconds was evaluated visually. Evaluation criteria are as follows.
Colorless: 2 or more out of 3 people answered that it is colorless Yellow: 2 out of 3 people say that it is yellow (3) Discoloration by alkaline detergent After spraying a spray on white cloth for about 2 seconds, immediately after applying an appropriate amount of alkaline detergent, white cloth The color change of was evaluated. Evaluation criteria are as follows.
No change: 3 out of 3 answered no change in color of white cloth Yellow color: 3 out of 3 answered that the color of white cloth changed to yellow

As shown in Table 1 above, in Example 1 in which octocrylene and t-butylmethoxydibenzoylmethane were used in combination as the ultraviolet light absorber, while the coloration of the stock solution was evaluated as colorless, the other ultraviolet light absorbers were evaluated. It can be seen that in the examples of Comparative Examples A to D in which Y was incorporated, yellowness was clearly increased. Also, with regard to the color when sprayed on a white cloth, Example 1 is similarly colorless and excellent, and has been colored yellow in the examples of Comparative Examples A to D in which other UV absorbers are blended. I understand that. In addition, in the color evaluation by the alkaline detergent, it was confirmed in Comparative Example D that a yellow color was developed.
From the above, it can be seen that using a combination of octocrylene and t-butylmethoxydibenzoylmethane as the ultraviolet light absorber is excellent from the viewpoint of suppressing the yellowness of the stock solution.

<Reference Examples 1 to 5>
As shown in Table 2, the color development of the alkaline detergent was evaluated about the ethanol solution of each ultraviolet absorber of the reference examples 1-5.
About evaluation of the color development of an alkaline detergent, a suitable quantity of reference examples 1 to 5 was applied to a white cloth and then an appropriate quantity of the alkaline detergent was applied, and then the color change of the white cloth was evaluated.
No change: 3 out of 3 answered no change in color of white cloth Yellow color: 3 out of 3 answered that the color of white cloth changed to yellow

  As shown in Table 2 above, octocrylene alone, t-butyl methoxydibenzoylmethane alone, and dimethyl PABA ethylhexyl alone resulted in no change in the color development of the alkaline detergent. In the example of Reference Example 4, the color development of the alkaline detergent was evaluated to be yellow. And in the example of the mixture of the reference example 5, it became evaluation that color development of an alkaline detergent colored yellow.

Examples 2 to 6
What mixed the non-aqueous spray hair cosmetic and propellant of Examples 2 to 6 was prepared with the composition shown in Table 3.
In Example 2, the pressure container was filled so that the amount of the propellant was 70 parts by weight with respect to 30 parts by weight of the stock solution. As a propellant, LPG having a pressure of 0.15 MPa at 20 ° C. was used.
In Example 3, the pressure container was filled so that the amount of the propellant was 85 parts by weight with respect to 15 parts by weight of the stock solution. As a propellant, LPG with a pressure of 20 MPa was applied at 0.3 MPa.
In Examples 4 to 6, the pressure container was filled so that the amount of the propellant was 85 parts by weight with respect to 15 parts by weight of the stock solution. As a propellant, LPG with a pressure at 20 ° C. of 0.15 MPa was loaded.
In Examples 2 to 6, as in the case of Example 1, as a pressure-resistant container, S13 series (stem hole diameter diameter 0.3 mm, housing horizontal hole diameter 0.6 mm, housing pilot hole diameter 0) manufactured by Mitani Valve Co., Ltd. .5 mm) was used. Moreover, the button used the thing of the mechanical brake up type (nozzle hole diameter diameter 0.43 mm) made from Mitani Valve.

The evaluation methods and criteria are shown below. The evaluation was conducted by three panelists.
The color of the undiluted solution, the color when sprayed on a white cloth, and the color change caused by the alkaline detergent are the same as described above.
(4) Degree of residence of visually perceived jetted object When the spray was sprayed for about 2 seconds, the amount and residence time of particles of jetted body flying in the air were visually evaluated. Here, in general, the residence time tends to be long when the amount of particles of the jetted material having a visible size is large, so the amount of particles of the jetted material of a visible degree is When the residence time is long, the degree of residence is high. When the amount of particles of the jetted material having a visible size is small and the residence time is short, the degree of residence is low. Evaluation criteria are as follows.
:: The retention degree of the visually perceived jetted object is small (3 out of 3 persons answered that the stagnation degree of the visually perceived jetted object is smaller than the standard)
:: The retention degree of the visually perceived jetted object is somewhat small (1 to 2 out of 3 persons answered that the stagnation degree of the visually perceived jetted object is smaller than the standard)
:: Equal to the standard (3 out of 3 persons answered that the standard is equivalent)
X: The retention degree of the visually perceived jetted object is somewhat high (1 to 2 out of 3 persons answered that the stagnation degree of the visually perceived jetted object is higher than the standard)
Xx: The retention degree of the visually perceived jetted object is high (3 out of 3 persons answered that the stagnation degree of the visually perceived jetted object is higher than the standard)

(5) Stickiness Spray was sprayed on the wig for about 2 seconds, and the degree of stickiness of the entire hair was evaluated sensoryally. Evaluation criteria are as follows.
○: There is no stickiness as in the standard (3 out of 3 persons answered that they are equal to the standard)
:: Slight stickiness (1 to 2 out of 3 persons answered that stickiness compared to the standard)
X: Stickiness (3 out of 3 respondents answered that it is sticky compared to the standard)
(6) Feel (slip)
The spray was sprayed into a wig for about 2 seconds, and the slip when passed by hand from the root to the tip was evaluated sensory. Evaluation criteria are as follows.
:: Good slip (3 out of 3 respond to a slip compared to the standard)
○: Slippage is somewhat good (1 to 2 out of 3 respondents answered that they slip compared to the standard)
:: Slippage is somewhat bad (1 to 2 out of 3 respondents answered that they do not slip compared to the standard)
X: Poor slipping (3 out of 3 answered that they did not slip compared to the standard)

(7) Gloss spray was sprayed for about 2 seconds, and the gloss (reflection of light) of appearance was sensory-evaluated. Evaluation criteria are as follows.
:: Good gloss (3 out of 3 people answered that there is gloss compared to the standard)
○: The gloss is a little better (1 to 2 out of 3 people answered that there is gloss compared to the standard)
:: The gloss is a little bad (1-2 out of 3 people answered that there is no gloss compared to the standard)
X: The gloss is bad (3 out of 3 people answered that there is no gloss compared to the standard)
(8) White floating of black cloth It was evaluated whether the black cloth was colored white when sprayed on the black cloth for about 2 seconds. Evaluation criteria are as follows.
None: Three out of three answered that there is no change in color compared to the standard. Yes: Three out of three answered that the color is white compared to the standard

As shown in Table 3 above, it can be seen that when the ratio of the stock solution to the propellant is increased, the degree of stickiness is deteriorated but the degree of retention of the visually visible jetted object is improved and decreased (see Example 1 and Example 2) .
In addition, when Example 1 and Example 3 are compared, the retention degree of visual recognition injection thing worsens, so that the gauge pressure in 25 degreeC is higher, although the compounding ratio of a undiluted | stock solution and a propellant is the same. I understand that.
Moreover, when Example 1 and Example 5 used as a reference | standard are compared, it is understood that the direction of compounding of highly polymerized dimethicone is improving the retention degree of visual recognition injection thing, touch (slip), and gloss.

Moreover, when Example 1 and Example 4 are compared, it turns out that stickiness worsens and the hand (sliding) is also deteriorated, when a nonionic surfactant is mix | blended.
Furthermore, when Example 1 and Example 6 are compared, it turns out that the way of blending the ultraviolet scattering agent which is an inorganic type compound is deteriorating the retention degree of the visual identification thing, stickiness, touch (slip), and gloss. . In addition, in Example 6 which mix | blended the ultraviolet-ray scattering agent which is an inorganic type compound, the whitening which was not confirmed in the other Example is confirmed.

  The present invention can be preferably used as a non-aqueous spray hair cosmetic and aerosol product capable of suppressing yellowing while suppressing damage to hair.
