[0020] The preferred embodiments for implementing the present technology are described below. It should be noted that the embodiments described below represent an example of representative embodiments of the present technology, and the scope of the present technology is not interpreted narrowly. It should be noted that in this specification, if not otherwise specified, the percentage is a mass percentage (mass / mass %). In addition, the upper limit (below) and lower limit (above) of each numerical range (~) can be arbitrarily combined as needed.

[0021] 1. About this technology

[0022] The present inventors have conducted in-depth research on a multi-layer protective composition containing an oily resin that can be expected to have a protective effect on makeup. The present technology is a multi-layer composition, so the appearance of the composition is different from the cosmetics of Patent Documents 1 to 3, and the concept or direction of the combination of the components is naturally very different.

[0023] Regarding the multi-layer makeup protection cosmetic using an oil-soluble film-forming silicone resin, the inventors have found that the multi-layer composition further blended with 40-95% of water and a volatile oil agent in the oil-soluble film-forming silicone resin has good mist fineness and makeup protection effect, but has a sticky feeling after application, and if the spray container is used continuously, the lipophilic resin will precipitate near the discharge port, causing the injection port or injection nozzle to be clogged. The present inventors believe that if a volatile oil agent is used in the composition, although the film-forming speed during use is good, the injection port or injection nozzle will be clogged over time. In addition, the inventors have found that, as shown in Reference Example 1 of [Examples] below, even if the composition containing an lipophilic resin, ethanol, water and a volatile oil agent further blended with ethanol, the injection port or injection nozzle will still be clogged over time.

[0024] Therefore, the main purpose of the present technology is to provide a multi-layer makeup protection cosmetic material, which has a good film-forming speed during use and a good non-sticky feel, and can prevent the injection port or injection nozzle from being blocked over time.

[0025] In addition, the present inventors have conducted intensive research and found that by preparing a composition containing an oleophilic resin, ethanol, a metal salt and a low-viscosity non-volatile oil agent, it is possible to provide a multi-layer makeup protection cosmetic material that has a good non-sticky feel and can prevent the injection port or injection nozzle from clogging over time (Examples 1 to 28). Moreover, the present technology has the following excellent advantages: even when a volatile oil agent is not used, it has a good film-forming speed of the oleophilic resin (Examples 1 to 4, etc.). In addition, the present technology also has the following excellent advantages: even when a medium-to-high viscosity non-volatile oil agent different from the low-viscosity non-volatile oil agent is also contained, it is possible to provide a multi-layer makeup protection cosmetic material that has a good film-forming speed during use and an excellent non-sticky feel, and can prevent the injection port or injection nozzle from clogging over time (Examples 25 and 26). In addition, the present technology has the following advantages: even if a volatile oil is contained, it can provide an excellent non-sticky feeling, prevent the ejection port or the ejection nozzle from clogging over time, and provide a multi-layer makeup protection cosmetic with a good film-forming speed during use (Examples 27 and 28). It should be noted that the composition of the present technology can be used as a cosmetic or a skin external preparation, and the components, composition, content, etc. described in detail below can be appropriately used.

[0026] This technology can provide a multilayer cosmetic with a makeup protection effect, which can be a skin external agent or a composition. And this technology also has the following advantages: the user can use it on the makeup that is usually performed, on the skin before makeup, or during makeup, and can prevent or suppress the removal of the usual makeup, and has a makeup protection effect. In addition, it has the effect of preventing secondary attachment to clothing and masks. In addition, even if it is mixed with cosmetics such as foundation, blush, and eye shadow, and sprayed on cosmetic brushes, cotton pads, and then applied to cosmetics, it can prevent or suppress the usual makeup from removing, and has a makeup protection effect. Therefore, this technology can meet the consumer's desire to improve the durability of individual specific makeup applied to the skin or face using their own handheld cosmetics. In addition, this technology can be appropriately applied or used to the user's desired makeup or when or after the desired makeup according to the makeup situation, method, repair (makeup repair), steps, techniques or techniques. It should be noted that this technology can prevent the makeup from being secondary attached to clothes or masks, etc., which is caused by spraying directly on clothes or masks that come into contact with the skin during makeup, thereby achieving a makeup protection effect. Although various usage methods can be adopted, from the perspective of makeup protection effect, it is preferably used on the makeup or on the skin before makeup, or during makeup.

[0027] In addition, the inventors have found that by using an oleophilic resin, it is easy to form a film that has an excellent barrier effect on particles in the atmosphere of air pollution such as pollen, PM2.5, and yellow sand (Patent Document 4: WO2020 / 175398). As shown in the following [Example], by using a multilayer composition containing at least an oleophilic resin for makeup, makeup removal can be prevented for a long time. This technology is used on the skin before or after makeup. In addition to protecting makeup, it can also be used as a composition for protecting the skin from air pollution, pollen, PM2.5, and air particles. In addition, this technology has the following advantages: various particles are not easily attached to the skin surface or makeup surface using the skin protection composition related to this technology.

[0028] The present technology is described in detail below.

This can provide a good non-sticky feel and prevent the ejection port or ejection nozzle from clogging over time. In addition, it also has the advantage of a good film-forming speed during use.

[0031] In addition to protecting makeup, the makeup protection cosmetic can also be used as a composition or a cosmetic for skin protection. In addition, the makeup protection cosmetic can also be used for protection measures or anti-adhesion purposes against PM2.5, pollen and other atmospheric particles.

[0110] The multi-layer makeup protection cosmetic of this embodiment maintains a good dispersion state for a certain period of time after mixing, so that it can be sprayed into fine mist particles. In addition, this embodiment can be a multi-layered form, and has excellent sprayability and film formation. This is because the lipophilic resin is mixed to form a combination of the above-mentioned components (A) to (D) and water. In addition, this embodiment has the following advantages: even if an emulsifier is not mixed, the spray particles are fine, so it can also be used as a makeup protection cosmetic without an emulsifier or with a reduced amount of emulsifier.

[0111] Furthermore, this embodiment has the following advantages: by combining the above-mentioned components (A) to (D), a highly water-resistant and sebum-resistant film brought by the lipophilic resin can be formed on the applied makeup, and a long-lasting makeup protection effect can be achieved. In addition, this embodiment can be sprayed on the entire face with fine mist particles, and a highly water-resistant and hydrophobic film can be formed on the entire face.

[0112] In addition, the viscosity (mPa·s) of the composition (preferably a cosmetic) of the present embodiment is preferably an average value of 1500 mPa·s or less as measured at 25°C using a B-type viscometer and rotor No. 2 at 6 rpm for 1 minute, and is further preferably 1000 mPa·s or less because the coarseness of the mist is excellent, which is more preferred.

[0176] (C) Push-type nozzle container (spray diameter A non-aerosol container) is filled with the water layer (B) and the oil layer (A) in this order to obtain a composition (multi-layer makeup protection cosmetic).

[0177] It should be noted that (1) to (25) may be filled in a container with a nozzle in a random order and shaken vigorously to obtain a composition (multi-layer makeup protection cosmetic).

[0178] <How to use the composition>

[0179] The composition used in this experiment was sprayed on the face after applying foundation, eye shadow, blush, etc. The composition used in this experiment was shaken 10 times and then sprayed 10 times on the entire face after applying makeup. The composition used in this experiment was evaluated by the following evaluation method. For example, in the evaluation method of "(2) Non-sticky feeling", the evaluation was conducted 5 minutes after spraying (drying).

[0180] (Evaluation method)

[0181] Ten professional cosmetics evaluators sprayed each multi-layer makeup protective material of the test example 10 times on the entire face with foundation and eye makeup applied, and evaluated and scored in five levels according to the following evaluation criteria for "(1) Makeup film formation speed", "(2) Non-sticky feeling", "(3) Anti-clogging effect", "(4) Makeup protection effect", and "(5) Coarseness of the mist". For items (1), (2) and (5), evaluation was performed during and immediately after use, and for item (4), the durability of the makeup was evaluated 8 hours after use in normal life. For item (3), the amount of spray at the beginning of use and the amount of spray at the end of use were compared. The average score of all evaluators was then calculated and judged according to the following judgment criteria.

[0182]

Evaluation criteria

[0183] (1) Cosmetic film formation speed: How fast the cosmetic film is formed after application

[0184] (Rating): (Evaluation results)

[0185] 4 points: A cosmetic film is formed within 5 minutes after application

[0186] 3 points: A cosmetic film is formed within 5 to 7 minutes after application

[0187] 2 points: A cosmetic film is formed within 7 to 9 minutes after application

[0188] 1 point: A cosmetic film is formed within 9 to 10 minutes after application

[0189] 0 points: No makeup film is formed even after 10 minutes of application

[0190] In addition, after shaking the nozzle container filled with the composition 10 times, the composition was sprayed 10 times on a glass plate (5 cm×5 cm), and the film formation of the composition applied on the glass plate was observed.

[0191] (2) Non-sticky feeling: Does it feel sticky after 5 minutes of application?

[0192] (Rating): (Evaluation results)

[0193] 4 points: Not sticky at all.

[0194] 3 points: Almost not sticky.

[0195] 2 points: Slightly sticky

[0196] 1 point: slightly sticky.

[0197] 0 points: Very sticky.

[0198] (3) Anti-clogging effect: Store at 5°C, spray 5 times a day at 5°C, and the average spray mass of 5 sprays at the end of the 30th day relative to the average spray mass of 5 sprays at the beginning of the test is the following ratio (N=3 average)

[0199] (Rating): (Evaluation results)

[0200] 4 points: above 95%

[0201] 3 points: less than 95% to more than 80%

[0202] 2 points: less than 80% to more than 65%

[0203] 1 point: less than 65% to more than 50%

[0204] 0 points: less than 50%

[0205] (3) Anti-clogging effect: Specifically, the composition used in the test was filled into three of the above-mentioned nozzle containers, and three nozzle containers filled with the same composition were prepared and stored at 5°C for 10 to 12 hours. After storage, for each container, the mass (mg) sprayed into the beaker when sprayed 5 times was measured under a 5°C environment. The total amount when the three containers were used was calculated, and the average mass (mg) sprayed from each container at the beginning of the test (day 1) was calculated based on the total amount. After the start of the test, the three containers continued to be stored at 5°C and sprayed 5 times a day under a 5°C environment. At the end of the 30th day, the mass (mg) sprayed into the beaker when sprayed 5 times was measured at the end of the 30th day, and the average mass (mg) sprayed from each container at the end of the test (day 30) was calculated in the same way as at the beginning of the test (N=3 average). Then, the ratio of the average ejection mass of 5 times at the end of the test to the average ejection mass of 5 times at the beginning of the test is calculated (that is, [average ejection mass of each container at the end of the test / average ejection mass of each container at the beginning of the test] × 100 (%)), and the score that meets the following evaluation result range (ratio) is the evaluation of the composition used in the test. The less the clogging of the ejection port or the ejection nozzle caused by the composition used, the smaller the difference between the ejection mass at the end of the test and the ejection mass at the beginning of the test, and the closer the evaluation result is to 100%.

Judgment criteria

[0221] (Average score): (Judgment)

[0222] 3.5 points or above: ◎ (Excellent)

[0223] 2.5 points or more and less than 3.5 points: ○ (Good)

[0224] 1.5 points or more and less than 2.5 points: △ (slightly unacceptable)

[0225] Less than 1.5 points: × (Not acceptable)

[0226] The compositions of Examples 1 to 28 and Reference Example 1 are multi-layered makeup protective materials divided into two layers, an upper oil layer and a lower water layer.

[0227] The viscosity of the compositions of Examples 1 to 28 at 25° C. was 1000 mPa·s or less. The viscosity of the composition was measured by shaking the composition 10 times and letting it stand using a B-type viscometer described in the above “Viscosity of the composition of the present embodiment (mPa·s)”.

[0228] According to the results of Tables 1 to 3, the composition of the present technology (Examples 1 to 28, Reference Example 1) can be sprayed gently and delicately on the entire face, so the applied makeup will not be damaged, and even general users can easily form a moderate and uniformly thick makeup film on the entire face. In addition, the composition of the present technology will not come off even if it is applied to the face for a long time of 8 hours, so it has high sebum resistance and can be considered to have excellent skin protection effect. In addition, these compositions preferably contain volatile oils, and when they contain water, the water content is preferably in the range of about 50 to 85% by mass, and can be adjusted to 1 to 95% by mass.

[0229] In addition, the protective composition of the present technology (Examples 1 to 28) contains component (A) lipophilic resin (film-forming resin), component (B) ethanol, component (C) metal salt, and component (D) low-viscosity non-volatile oil agent, so the coarseness of the mist during spraying, the makeup protection effect and film-forming speed, the non-sticky feel, and the clogging prevention effect are all excellent. In addition, the preferred mass ratio of (B) / (A) is in the range of 1 to 200, and the more preferred range is 2 to 100. In addition, the preferred mass ratio of (C) / (A) is in the range of 0.1 to 20, and the more preferred range is 0.2 to 10. In addition, the preferred mass ratio of (A) / (D) is 0.01 to 6, and the more preferred range is 0.1 to 3.

[0230] In addition, the protective composition containing a hydrophilic resin, a volatile oil agent, and water is not preferred due to stickiness and a heavy feeling (see Patent Document 4), but the protective composition of Reference Example 1 containing a metal salt as component (C) obtained a non-sticky feeling of "◎ (excellent)". However, the protective composition of Reference Example 1 did not exhibit a clogging prevention effect. In addition, the compositions of Comparative Examples 1 to 5 did not obtain a makeup protection effect, and other evaluations were also poor.

[0231] The protective composition of the present technology (e.g., Example 1) exhibited a very excellent result in comparison with the protective composition of Reference Example 1, by changing the volatile oil agent to the low-viscosity non-volatile oil agent of component (D), so that the clogging prevention effect was changed from "× (unacceptable)" to "◎ (excellent)". In addition, by combining the low-viscosity non-volatile oil agent and the volatile oil agent, the clogging prevention effect was not reduced, and very excellent results were obtained in the items of the coarseness of the mist during spraying, the makeup protection effect and the non-sticky feeling during use, and the clogging prevention effect of the injection port or the injection nozzle.

[0232] In addition, for the low viscosity (25°C: kinematic viscosity) of the non-volatile oil, use 100 mm 2 / s or less (Example 25), excellent results were obtained in the items of fineness of the mist during spraying, makeup protection effect, non-sticky feeling, and clogging prevention effect. In addition, even when a non-volatile oil agent with a higher viscosity was further blended with a low-viscosity non-volatile oil agent, excellent results were obtained in the items of fineness of the mist during spraying, makeup protection effect, non-sticky feeling, and clogging prevention effect of the injection port or injection nozzle. This is probably because the overall kinematic viscosity of the non-volatile oil agents combined was significantly reduced to less than 300 mm. 2 / s or about 100mm 2 / s or less.

[0233] In summary, the protective composition of the present technology contains component (A) lipophilic resin (film-forming resin), component (B) ethanol, component (C) metal salt, and component (D) low-viscosity non-volatile oil agent, and the results of the items such as the fineness of the mist during spraying, the makeup protection effect and the non-sticky feeling during use, and the effect of preventing the clogging of the injection port or injection nozzle are all excellent. In addition, by further containing water and / or a volatile oil agent, the fineness of the mist during spraying, the makeup protection effect and the non-sticky feeling during use, and the effect of preventing the clogging of the injection port or injection nozzle are all very excellent.
