Description

The present invention relates to a skin cosmetic composition, and more specifically, to a skin cosmetic composition that has excellent moisturizing effects and reduces redness of the skin, while suppressing stickiness, and contributes to normalizing cell turnover and improving the skin barrier function.

Currently, skin cosmetics containing various naturally derived ingredients such as plant extracts, polysaccharides, and amino acids that have low irritation, irritation-relieving, and anti-inflammatory properties are being introduced with the expectation that they can be used gently on sensitive or dry skin.

For example, Sanguinea oleracea is a naturally derived ingredient with excellent moisturizing effects (e.g., Patent Documents 1 and 2). However, when incorporated into cosmetics, it can cause stickiness and other issues that reduce the feel when used.

Passionflower is also known as a naturally derived ingredient that reduces redness in the skin (e.g., Patent Document 3), but when added to cosmetics, it can cause stickiness and other issues that reduce the feel when used.

Therefore, there has been a strong demand for skin cosmetics that use naturally derived ingredients to provide moisturizing effects and suppress redness of the skin, while not compromising the feel of use, such as stickiness.

JP 2000-327552 A Japanese Patent Application Laid-Open No. 11-29460 JP 2018-48103 A

The present invention was made in consideration of the above problems, and its objective is to provide a skin cosmetic composition and a stickiness suppressant for skin cosmetics that have excellent moisturizing effects and reduce skin redness while also suppressing stickiness.

As a result of intensive research conducted by the inventors to solve the above problems, they discovered a skin cosmetic composition that combines Angelica keiskei extract, yuzu fruit extract, and glucosyl trehalose to provide excellent moisturizing effects and reduce skin redness while also reducing stickiness, thus completing the present invention.

The first invention is
The skin cosmetic composition contains the following components (A) to (C):
(A) Angelica keiskei extract (B) Yuzu fruit extract (C) Glucosyl trehalose The second invention is
In the skin cosmetic composition, the blending amount of (C) relative to (A) and (B), ((C)/(A+B)), is 0.25 or more.
The third invention is
The stickiness-reducing agent for skin cosmetics of (A) and/or (B) contains the component (C) as an active ingredient.

The present invention provides a skin cosmetic composition and a stickiness inhibitor for skin cosmetics that are excellent in moisturizing effect and reducing redness of the skin while suppressing stickiness. Even more surprisingly, it has been found that the skin cosmetic composition of the present invention also contributes to normalizing cell turnover and improving the barrier function.

The composition of the present invention will be described in detail below. The skin cosmetic composition of the present invention can exert the effects of the present invention by containing the following components: (A) Angelica keiskei extract, (B) Yuzu fruit extract, and (C) glucosyl trehalose.

In this specification, "skin redness" refers to redness caused by capillary expansion and increased blood flow to suppress inflammation. "Turnover" refers to the regeneration of epidermal cells in a certain cycle, specifically, the cycle in which basal cells produced in the basal layer divide, are pushed up toward the surface of the skin, and then become dandruff and fall off. This cycle is repeated to maintain the barrier function of the skin and maintain a healthy and beautiful skin condition. On the other hand, it is thought that turnover is disrupted due to the effects of aging, dryness, ultraviolet rays, etc., causing abnormalities in the formation of stratum corneum cells and the structure of intercellular lipids. It is known that this causes various skin diseases and skin troubles such as rough skin. "Normalizing turnover" means normalizing skin in such a state of disrupted turnover. "Moisture" is defined as the feeling of being moist and not sticky when touched with the hand after using the skin cosmetic composition, feeling moist without an oily film feeling, and having a natural glossy, bright, and healthy appearance.

<(A) Angelica keiskei extract>
The component (A) used in the skin cosmetic composition of the present invention is an extract of Angelica keiskei. The extract of Angelica keiskei is an extract extracted from Angelica keiskei, and can be obtained by extracting the plant as is or after crushing with water, a lower alcohol such as ethanol, a polyhydric alcohol such as propylene glycol or 1,3-butylene glycol, a polyhydric alcohol alkyl ether such as diethylene glycol ether, or other polar solvent, or a mixture thereof, but is not limited thereto. In addition, the extract of Angelica keiskei is preferably an extract of the leaves and stems of Angelica keiskei, but is not limited thereto.

These ingredients are available as commercially available cosmetic ingredients. Examples of commercially available products include "Ashitaba Extract BG (manufactured by Koei Kogyo Co., Ltd.)", "Falcorex Ashitaba B (manufactured by Ichimaru Pharcos Co., Ltd.)", "Waism <Ashitaba> (manufactured by Maruzen Pharmaceutical Co., Ltd.)" and "Ashitaba Extract BG (manufactured by Yamada Yaken Co., Ltd.)".

Angelica keiskei extract is known to have moisturizing properties, promote hyaluronic acid production, promote collagen production, and have antioxidant properties, but in this invention, it has been discovered that it also has a turnover normalizing effect, contributing to improved barrier function.

The blending amount of component (A) is preferably 0.001% to 3% of the total weight of the skin cosmetic composition, and more preferably 0.005% to 1%. If it is 0.001% or more, a sufficient moisturizing effect is obtained and it is also suitable for normalizing cell turnover. On the other hand, if it is 3% or less, stickiness can be suppressed by combining it with component (C) described below.

<(B) Yuzu Fruit Extract>
Component (B) used in the skin cosmetic composition of the present invention is a yuzu fruit extract. The yuzu fruit extract is an extract extracted from the fruit of yuzu (Citrus junos), and can be obtained by extracting the fruit, either directly or after crushing, with water, a lower alcohol such as ethanol, a polyhydric alcohol such as propylene glycol or 1,3-butylene glycol, a polyhydric alcohol alkyl ether such as diethylene glycol ether, or other polar solvents, or mixtures thereof, but is not limited thereto.

These ingredients are available as commercially available cosmetic ingredients. Examples of commercially available products include "Falcorex Yuzu E (manufactured by Ichimaru Pharcos Co., Ltd.)", "Yuzu Ceramide B (manufactured by Ichimaru Pharcos Co., Ltd.)", "Waism <Tosa Yuzu> (manufactured by Maruzen Pharmaceutical Co., Ltd.)", and "Yuzu Extract-J (manufactured by Maruzen Pharmaceutical Co., Ltd.)".

Yuzu fruit extract is known to have astringent, moisturizing, and blood circulation promoting effects, but in the present invention it is used to improve skin redness.

The amount of component (B) used in the skin cosmetic composition of the present invention is preferably 0.001% to 3%, and more preferably 0.005% to 1%. If it is 0.001% or more, redness of the skin can be improved, and if it is 3% or less, stickiness can be suppressed by combining it with component (C) described below.

<(C) Glucosyltrehalose>
The component (C) used in the skin cosmetic composition of the present invention is glucosyltrehalose. Glucosyltrehalose is a non-reducing carbohydrate having a structure in which 1 to 3 glucose units are bound to trehalose. These components are available as commercially available cosmetic raw materials. An example of a commercially available product is "Tornale (manufactured by Hayashibara Co., Ltd.").

Glucosyltrehalose is known to be used as a binder, emulsion stabilizer, film former, moisturizer, and skin protectant, but in the present invention, it has been found that glucosyltrehalose suppresses stickiness caused by components (A) and (B).

More surprisingly, in the present invention, it was found that while glucosyltrehalose alone does not improve the barrier function, adding glucosyltrehalose to component (A) synergistically improves the barrier function of (A).

The amount of component (C) is preferably 0.001% to 3%, and more preferably 0.005% to 1%. If it is 0.001% or more, the stickiness caused by components (A) and (B) can be suppressed, and if it is 3% or less, the component (C) will not cause wrinkling during application.

The ratio of the amount of component (C) to the amount of components (A) and (B) ((C)/(A+B)) is preferably 0.25 or more. If it is 0.25 or more, the stickiness caused by the combined use of components (A) and (B) can be improved.

<Other ingredients>
In addition to the components described above, the skin cosmetic composition of the present invention may contain other components, such as anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, oils, polymeric compounds, thickeners, powders (colorants, resins, pigments), preservatives, fragrances, moisturizers, physiologically active ingredients, mineral salts, solvents, antioxidants, chelating agents, pearlizing agents, neutralizing agents, pH adjusters, plant extracts other than those listed under component (C) used in the skin cosmetic composition of the present invention, enzymes, and the like, as appropriate, within the scope of the object of the present invention.

The skin cosmetic composition of the present invention may also contain a suitable amount of physiologically active ingredients, provided that the purpose of the present invention is not impaired. A physiologically active substance is a substance that imparts some physiological activity to the skin when applied to the skin, and examples of such substances include anti-inflammatory agents, anti-aging agents, UV protection agents, astringents, antioxidants, blood circulation promoters, antibacterial agents, germicides, drying agents, cooling agents, warming agents, vitamins, amino acids, wound healing promoters, irritation mitigators, analgesics, and cell activators.

<Skin cosmetics>
The skin cosmetic composition of the present invention can be produced according to a conventional method. Examples of the skin cosmetic composition of the present invention include lotions, milky lotions, creams, gels, serums, sheet masks, makeup, body lotions, body gels, body creams, makeup bases, etc. The dosage form can also be selected arbitrarily depending on the purpose. That is, examples include liquids, creams, gels, milky lotions, sheets, sticks, aerosols, etc. The skin cosmetic composition of the present invention is not limited to general cosmetics, but includes quasi-drugs, designated quasi-drugs, external medicines, etc.

△: Somewhat poor (the average score of the five participants was 2 points or more but less than 3 points)
×: Poor (the average score of 5 people was less than 2 points)

2. Skin Moisture Evaluation Test The forearms of 10 evaluation panelists were washed with lukewarm water, and then allowed to acclimate for 20 minutes in an environment with a temperature of 25°C and a relative humidity of 50%. Then, an appropriate amount of the skin cosmetic composition of the present invention and the comparative example was applied, and the skin was allowed to acclimate for 20 minutes again in an environment with a temperature of 25°C and a relative humidity of 50%, after which the stratum corneum moisture content (conductance value) was measured using a Corneometer (MPA580, Courage+Khazaka). The moisturizing effect was evaluated by calculating the moisturizing effect (%) from the following formula, averaging the values of the five panelists, and based on the following criteria.
<Skin moisturizing effect rating>
Moisture effect (%) = (skin moisture content of stratum corneum after application / skin moisture content of stratum corneum before application) x 100
(Evaluation criteria for skin moisturizing effect)
⊚: Moisturizing effect (%) was 150% or more.
Good: The moisturizing effect (%) was 125% or more and less than 150%.
Δ: Moisturizing effect (%) was 100% or more and less than 125%.
×: Moisturizing effect (%) was less than 100%.

3. Evaluation test of skin moisture After washing the forearms of 10 evaluation panelists with lukewarm water, each was allowed to acclimate for 20 minutes in an environment at a temperature of 25°C and a relative humidity of 50%. Then, an appropriate amount of the skin cosmetic composition of the present invention and the comparative example was applied, and after acclimatization for 20 minutes again in an environment at a temperature of 25°C and a relative humidity of 50%, a sensory evaluation of skin moisture was performed using the following scoring method. The evaluation of skin moisture was classified as follows, using the average value of the total scores of the five panelists according to the following evaluation criteria.

△: Somewhat poor (the average score of the five participants was 2 points or more but less than 3 points)
×: Poor (the average score of 5 people was less than 2 points)

4. Redness Improvement Effect Measurement Ten evaluation panelists were subjected to continuous application of appropriate amounts of the skin cosmetic compositions of the Examples and Comparative Examples of the present invention for 10 days. The test sites before and after continuous application were measured using a color difference meter (CM-700d: manufactured by Konica Minolta) and the a* value was quantified. The redness improvement effect was evaluated based on the following criteria, with the redness reduction rate (%) calculated from the following formula and the average value of the five panelists being calculated. The greater the redness reduction rate, the greater the redness improvement effect.
<Score for redness improvement effect>
Redness reduction rate (%) = (a* value of skin after continuous use / a* value of skin before continuous use) x 100
(Evaluation criteria for redness improvement effect)
⊚: Redness reduction rate (%) was 5% or more.
Good: The redness reduction rate (%) was 2.5% or more and less than 5%.
Δ: The redness reduction rate (%) was 0% or more and less than 2.5%.
×: The redness reduction rate (%) was less than 0%.

5. Measurement of turnover normalization effect Ten evaluation panel members were subjected to continuous application of appropriate amounts of the skin cosmetic compositions of the examples and comparative examples of the present invention for 10 days. Before and after continuous application, the forearms were washed with lukewarm water, and then allowed to acclimate for 20 minutes in an environment of 25°C and 50% relative humidity. Next, cellophane tape (manufactured by Nichiban) 4 cm x 2.5 cm was applied to the measurement site of the forearm and peeled off. This application-peel off operation was repeated five times to collect the stratum corneum. The peeled cellophane tape was then observed under a microscope (manufactured by Keyence Corporation, VHX-1000). The turnover normalization effect was scored in three items, "cell morphology,""multiplepeeling," and "arrangement regularity," on a five-level evaluation scale as shown below. Furthermore, the total score of the two items was calculated using the following formula, and the evaluation was performed based on the following criteria. The results are shown in the table.
<Score for turnover normalization effect>
Turnover normalization effect (points) = (evaluation standard points for cell morphology, multiple detachment, and regularity of cell arrangement after continuous use) - (evaluation standard points for cell morphology, multiple detachment, and regularity of cell arrangement before continuous use)
(Cell morphology evaluation criteria)
5 points: the cells are clearly pentagonal or hexagonal; 4 points: the cells have some corners; 3 points: the cells have almost no corners; 2 points: the cells are slightly rounded; 1 point: the cells are generally rounded (evaluation criteria for multiple detachment)
5 points: Less than 20% of the removed stratum corneum cells are overlapping; 4 points: Between 20% and less than 40% of the removed stratum corneum cells are overlapping; 3 points: Between 40% and less than 60% of the removed stratum corneum cells are overlapping; 2 points: Between 60% and less than 80% of the removed stratum corneum cells are overlapping; 1 point: Between 80% and more of the removed stratum corneum cells are overlapping (criteria for evaluation of arrangement regularity)
5 points: 80% or more of cells are arranged neatly and without gaps; 4 points: 60% or more but less than 80% of cells are arranged neatly and without gaps; 3 points: 40% or more but less than 60% of cells are arranged neatly and without gaps; 2 points: 20% or more but less than 40% of cells are arranged neatly and without gaps; 1 point: Less than 20% of cells are arranged neatly and without gaps (evaluation criteria for turnover normalization effect)
⊚: Turnover normalization effect (score) was 4 points or more and less than 6 points.
◯: Turnover normalization effect (points) was 2 points or more and less than 4 points.
Δ: Turnover normalizing effect (points) was 0 points or more and less than 2 points.
×: Turnover normalization effect (points) was 0 points or less.

6. Barrier function effect measurement test A continuous use test was conducted for one week in which the skin cosmetic of the present invention was applied to either the left or right forearm of five panels, and pure water was applied to the other forearm, twice a day at 0.05 mL/cm2. Before and after continuous use, the measurement site was washed with lukewarm water, and then, after 20 minutes of acclimation in an environment of 25°C and 50% relative humidity, the transepidermal water loss (TEWL value) of the stratum corneum of the forearm was measured using a tewameter (MPA580, Courage+Khazaka). The TEWL value can be used to confirm the barrier function of the stratum corneum, and it is possible to examine the effect of improving rough skin and the effect on skin smoothness. The barrier function effect was evaluated by calculating the barrier function effect (%) from the following formula to obtain the average value of the five panels, and based on the following criteria.
<Score and details regarding barrier function effect>
Barrier function effect (%) = {1 - (amount of moisture lost from stratum corneum one hour after application / amount of moisture lost from stratum corneum before application)} x 100
(Evaluation criteria for the barrier function effect measurement test)
⊚: Barrier function effect (%) was 30% or more.
Good: The barrier function effect (%) was 10% or more and less than 30%.
Δ: The barrier function effect (%) was −10% or more and less than 10%.
×: The barrier function effect (%) was less than −10%.
