Description

[Technical field]

[0001] The present invention relates to a cosmetic composition and a cosmetic composition for hair. [Background technology]

[0002] Skin and hair are easily damaged by ultraviolet rays, heat (hair dryers, etc.), friction (brushing), etc. Hair damage can be felt particularly in changes to the feel of the hair, such as thinning, loss of elasticity and strength, and difficulty in running your fingers through it. Hair damage can also be felt in changes to the appearance, such as loss of shine and slackness.

[0003] Normally, hair is protected by the cuticle. Dyed hair is protected by the cuticle with the pigment fixed inside the hair. When dyed hair is damaged by ultraviolet rays or the like, the long-chain fatty acids on the surface of the cuticle are released and the hair is damaged. Then, the pigment is removed from the damaged cuticle, and the hair becomes prone to fading. Therefore, by preventing damage to dyed hair and making it difficult for the pigment to be removed from the cuticle, the color retention of dyed hair can be improved.

[0004] Patent Document 1 discloses a technique for a hair composition containing a color fading suppressing component. However, this technique is intended to suppress color fading (discoloration) of dyed hair caused by heat, but is not intended to suppress color fading caused by ultraviolet rays.

[0005] Patent Document 2 discloses a technology relating to a cosmetic composition for improving hair strength. However, this technology does not suppress color fading of dyed hair due to ultraviolet rays. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 7281931 [Patent Document 2] Special Publication No. 2015-513560 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been made in consideration of the above problems and circumstances, and an object of the present invention is to provide a cosmetic composition and a hair cosmetic composition that reduce damage caused by ultraviolet rays and are less sticky. [Means for solving the problem]

[0008] In order to solve the above problems, the present inventors investigated the causes of the above problems and discovered that a cosmetic composition containing a fermentation product of a plant extract with lactic acid bacteria can reduce damage caused by ultraviolet rays and suppress stickiness, thereby arriving at the present invention. That is, the above-mentioned problems of the present invention are solved by the following means.

[0009] 1. Contains almond extract fermented by lactic acid bacteria A cosmetic composition comprising:

[0010] 2. It is oily 2. The cosmetic composition according to claim 1,

[0011] 3. Also contains shea butter 3. The cosmetic composition according to claim 1 or 2,

[0012] 4. The content of the fermented product is within the range of 0.008 to 0.170% by mass relative to the total mass of the cosmetic composition. 3. The cosmetic composition according to claim 1 or 2,

[0013] 5. The lactic acid bacteria is a bacillus. 3. The cosmetic composition according to claim 1 or 2,

[0014] 6. The lactic acid bacterium is a member of the genus Lactobacillus. 6. The cosmetic composition according to claim 5,

[0016] 8. For use on dyed hair 8. The hair cosmetic composition according to claim 7,

[0017] 9. Use as a styling product or leave-in treatment 8. The hair cosmetic composition according to claim 7, Effect of the Invention

[0018] According to the above-mentioned means of the present invention, it is possible to provide a cosmetic composition which reduces damage caused by ultraviolet rays and is less sticky.

[0019] Although the mechanism by which the effects of the present invention are manifested or the mechanism by which the effects of the present invention are acted upon has not been clearly understood, it is speculated as follows.

[0020] It is known that the intake of almonds strengthens the skin's ability to protect itself from UVB (ultraviolet B rays). However, according to the inventors, although the relationship with ultraviolet rays is unclear, the inventors found that the function of reducing damage caused by ultraviolet rays is dramatically improved by further fermenting the components extracted from almonds with lactic acid bacteria. In particular, it was found that the color retention of dyed hair is improved (fading can be suppressed).

[0021] Additionally, ingredients extracted from almonds contain many antioxidants, such as vitamin E. Antioxidant action refers to the ability to inhibit oxidation caused by active oxygen, and one of the causes of active oxygen is ultraviolet light. Although it is not clear, it is believed that ingredients with antioxidant action likely contribute to reducing damage caused by ultraviolet light.

[0022] The cosmetic composition of the present embodiment contains the fermented product and thus has the function of absorbing ultraviolet rays. Therefore, it is considered that by applying the cosmetic composition to skin, hair, etc., damage to skin, hair, etc. caused by ultraviolet rays can be reduced.

[0023] Compared to ultraviolet absorbers that have conventionally been used in cosmetic compositions, the fermented product is less sticky, and it is believed that stickiness can also be suppressed in cosmetic compositions containing the fermented product.

[0024] Fermented products also contain a lot of lactic acid, which is a natural moisturizing factor (NMF), and so applying them to skin or hair is thought to help maintain moisture and give the skin or hair a smooth feel. [Brief description of the drawings]

[0025] [Figure 1] SEM images of hair a in Example 1 and Comparative Example 4 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The cosmetic composition of the present embodiment is characterized by containing a fermentation product of an almond extract with lactic acid bacteria. This feature is a technical feature common to or corresponding to the following embodiments.

[0027] In this embodiment, from the viewpoint of imparting a smooth feel to the skin and hair, an oily composition is preferable.

[0028] In this embodiment, it is preferable to further contain shea butter from the viewpoint of improving color retention for dyed hair.

[0029] In this embodiment, from the viewpoint of being able to adequately impart the ultraviolet absorbing function to the cosmetic composition and obtaining sufficient storage stability, it is preferable that the content of the fermented product is within the range of 0.008 to 0.170 mass % relative to the total mass of the cosmetic composition.

[0030] In this embodiment, from the viewpoint of obtaining the effects of the present invention significantly, the lactic acid bacteria are preferably bacilli, and more preferably the lactic acid bacteria belong to the genus Lactobacillus.

[0031] The hair cosmetic composition of the present embodiment is characterized by containing the above-mentioned cosmetic composition.

[0032] The hair cosmetic composition of the present embodiment is preferably used on dyed hair, from the viewpoint of also obtaining the effect of improving color retention.

[0033] The hair cosmetic composition of the present embodiment is preferably used as a styling agent or a leave-in treatment, from the viewpoint of obtaining the effects of the present invention prominently.

[0034] The present invention, its components, and modes and aspects for carrying out the present invention will be described in detail below. In this application, the symbol "to" is used to mean that the numerical values ​​before and after the symbol "to" are included as the lower limit and upper limit.

[0035] 1. Overview of cosmetic compositions The cosmetic composition of the present embodiment is characterized by containing a fermentation product of an almond extract with lactic acid bacteria. In this specification, the term "cosmetic" refers to cosmetics and quasi-drugs, and the cosmetic is used by applying it to the skin or hair.

[0036] Natural ingredients such as plants contain many components. Therefore, it is known that natural ingredients such as plants exert useful functions on the human body that cannot be obtained from chemically synthesized ingredients. In recent years, natural ingredients such as plants are blended as active ingredients in many cosmetics.

[0037] Sugar is broken down into lactic acid, organic acids, etc. by the enzymes contained in lactic acid bacteria. This series of processes is called "fermentation." The components obtained by fermentation with lactic acid bacteria are significantly different from the original components. Therefore, the components after fermentation may have functions that the components before fermentation did not have, and in recent years, fermented products of components extracted from plants have been attracting attention.

[0038] The inventors have found that by further fermenting the components extracted from almonds with lactic acid bacteria, the function of reducing damage caused by ultraviolet rays is dramatically improved. In particular, it has been found that the color retention of dyed hair is improved (fading can be suppressed).

[0039] 2. Components of the cosmetic composition The cosmetic composition of the present embodiment may contain, in addition to the fermentation product of an almond extract with lactic acid bacteria, known ingredients contained in cosmetic compositions, such as vegetable oils and fats, as necessary.

[0040] (1) Almond extract fermented with lactic acid bacteria In this specification, "fermentation product of almond extract with lactic acid bacteria" refers to a product obtained by fermenting almond extract with lactic acid bacteria, and is also simply referred to as "fermentation product."

[0041] In reality, plant extracts contain many components, some of which are decomposed and fermented by enzymes derived from lactic acid bacteria. Therefore, the "fermented product" contains components contained in the almond extract that are not involved in the fermentation reaction, lactic acid bacteria, and components newly produced by fermentation. The "components newly produced by fermentation" include not only the components produced by decomposition with enzymes derived from lactic acid bacteria, but also components produced by the reaction of these and other components.

[0042] (1.1) Almond extract The scientific name for almonds is "Prunus dulcis" or "Prunus amygdalus." The almond extract is not particularly limited as long as it is extracted from almonds. The extract includes not only those extracted with a solvent, but also raw materials and dried products. The part to be extracted may be any of leaves, flowers, seeds, buds, etc., but among them, seeds are preferable. These may be used as they are, or may be processed by crushing or the like.

[0043] The form of the extract is not particularly limited, and examples thereof include the extract itself, a diluted solution of the extract, a concentrated solution of the extract, a dried product thereof, a roughly purified product thereof, and a purified product thereof.

[0044] When extracting with a solvent, the extraction method and the extraction solvent are not particularly limited. Examples of the extraction method include immersion in the extraction solvent and extraction with supercritical carbon dioxide.

Among these, Lactobacillus plantarum is preferred from the viewpoints of efficient proliferation and strong activity of the fermented product obtained.

[0049] The form of the lactic acid bacteria is not particularly limited, and may be, for example, a lactic acid bacteria powder. Specific examples include freeze-dried cells, cells treated with an enzyme and freeze-dried, etc. In addition to powder, the lactic acid bacteria may be in the form of a culture solution. Specific examples include a culture solution containing the cells, a culture supernatant, etc. In addition, the cells may be centrifuged, treated with an enzyme, etc., as necessary. Examples of the enzyme in the enzyme treatment include protease, lipase, etc.

[0050] (1.3) Fermented products The plant extract is fermented by lactic acid bacteria to obtain a fermented product. The fermentation conditions such as fermentation time and fermentation temperature are not particularly limited and can be adjusted as necessary. The fermentation method is also not particularly limited and can be, for example, static fermentation, stirring fermentation, shaking fermentation, and aeration fermentation.

[0051] The cosmetic composition of the present embodiment may contain the entire fermented product obtained by fermenting a plant extract with lactic acid bacteria, or may contain only a portion of the fermented product. However, when the cosmetic composition contains only a portion of the fermented product, it must contain the components newly produced by fermentation.

[0052] The form of the fermented product is not particularly limited and can be appropriately selected as needed. Examples of the form of the fermented product include a filtrate obtained by filtering the fermented product through a filter, a powder material obtained by freeze-drying the filtrate, and the like.

[0053] Examples of fermented almond extract include the Japan Cosmetic Industry Association's Ingredient Display Name: "Lactobacillus / Almond Seed Extract Ferment Filtrate" and the INCI Name: "Lactobacillus Prunus Amygdalus Dulcis (Sweet Almond) Seed Extract Ferment Filtrate."

[0092] 4. Manufacturing method of cosmetic composition The cosmetic composition of the present embodiment can be produced by uniformly mixing the above-mentioned components in predetermined amounts using a known method. EXAMPLES

[0093] The present invention will be described in detail below with reference to examples, but the present invention is not limited thereto. In the examples, the terms "parts" and "%" are used, but they represent "parts by mass" or "% by mass" unless otherwise specified. In the following examples, operations were carried out at room temperature (25° C.) unless otherwise specified.

[0094] 1. Preparation of Cosmetic Composition (1) Preparation of Cosmetic Composition 1 The following components were stirred at room temperature for 5 minutes to obtain cosmetic composition 1. Fermented almonds 0.17 parts by weight Caprylic / capric triglyceride 99.83 parts by weight The almond fermented product used was the Japan Cosmetic Industry Association ingredient name: "Lactobacillus / Almond Seed Extract Ferment Filtrate" and the INCI name: "Lactobacillus Prunus Amygdalus Dulcis (Sweet Almond) Seed Extract Ferment Filtrate."

[0095] (2) Preparation of Cosmetic Compositions 2 to 9 Cosmetic compositions 2 to 9 were obtained in the same manner as in preparation of cosmetic composition 1, except that the types and contents of the components were changed as shown in Tables I and II. Note that the "remaining amount" in Tables I and II refers to the remaining amount when the total amount is 100% by mass.

[0096] 2. Hair test Hair test bundles "Models: BM-WA and BS-C" (100% gray hair, manufactured by Beaulax) were dyed with a commercially available hair dye "Freshlight Milky Hair Color Champagne Pink" (manufactured by Henkel Japan). The dyed hair test bundles were then washed with a commercially available shampoo and rinsed with running water. The amount of shampoo was the same for each test. The dyed hair test bundles were then dried with a hair dryer to obtain dyed hair test bundle a (hair a).

[0097] 3. Evaluation Each cosmetic composition was subjected to the following evaluations.

[0098] (1) Stickiness evaluation (sensory evaluation) Each cosmetic composition was applied evenly to hair a and allowed to dry naturally. After that, hair a was touched and the stickiness was evaluated by two panelists on a 5-point scale. 5: Does not feel sticky at all. 4: Almost no stickiness. 3: Doesn't feel too sticky. 2: Neither. 1: Feels sticky.

[0099] The total score of the two panelists' five-point evaluation was used as the evaluation score, and the evaluation was performed according to the following criteria, where C or higher (A to C) was considered to be satisfactory for practical use. A: The evaluation score is 8 points or more (average score is 4 or more). B: The evaluation score is 6 or 7 points (average value 3 or 3.5). C: Evaluation score is 4 or 5 points (average value 2 or 2.5). D: The evaluation score is 3 points or less (average score is 1.5 or less).

[0100] Using the same evaluation method, each cosmetic composition was applied evenly to the skin and allowed to dry naturally. After that, the skin was touched and the sticky feeling was evaluated by two panelists on a 5-point scale. The evaluation results for the skin were the same as those for hair A.

[0101] (2) Hair cuticle evaluation Each cosmetic composition was applied evenly to hair a and allowed to dry naturally. Thereafter, the condition of the hair surface was photographed and observed using a scanning electron microscope (SEM) "TM4000Plus" (manufactured by Hitachi High-Tech Fielding Corporation). The condition of the hair surface was evaluated according to the following criteria. Note that a grade of C or higher (A to C) was deemed to be satisfactory for practical use. A: There is absolutely no peeling of the cuticle. B: There is almost no peeling of the cuticle. C: Cuticle peeling is only partially visible. D: Peeling of the cuticle is observed.

[0102] 1 shows SEM images of hair a in Example 1 and Comparative Example 4. No peeling of the cuticle was observed in hair a (Example 1) to which cosmetic composition 1 was applied, whereas it was found that the cuticle was peeled off overall in hair a (Comparative Example 4) to which cosmetic composition 9 was applied.

[0103] (3) Smoothness evaluation Each cosmetic composition was applied evenly to hair a and allowed to dry naturally. After that, a multipurpose hair tester "fibra.one" (manufactured by DiaStron) was used to slide a loaded contact on the surface of the hair bundle to measure the friction coefficient of the hair surface. The smaller the friction coefficient value, the smoother the hair is.

[0104] (4) Color retention evaluation (sensory evaluation) Each cosmetic composition was applied evenly to hair a. Then, the hair was irradiated with ultraviolet light for 24 hours using a UVA / UVB lamp. The irradiation conditions were: UVB: intensity 610 μW / cm 2 24 hours, UVA: 513μW / cm 2The hair a was washed with a commercially available shampoo, rinsed with running water, and then air-dried. The color fading inhibition effect (color retention) was visually evaluated according to the following criteria. A grade of C or higher (A to C) was deemed to be satisfactory for practical use. A: The color retention is extremely good. B: The color lasts very well. C: Color retention is good. D: The color doesn't last long.

[0105] (5) Color retention evaluation (color difference meter evaluation) First, for the hair test bundles before dyeing, "Model No.: BM-WA and BS-C" (100% gray hair, manufactured by Beaulax), * a * b * L in color space * , a * and b * was measured using a spectrophotometer "CM-700d" (manufactured by Konica Minolta Japan). Next, each cosmetic composition was applied uniformly to hair a. Then, ultraviolet light was irradiated for 24 hours using a UVA / UVB lamp. The irradiation conditions were as follows: UVB: intensity 610 μW / cm 2 24 hours, UVA: 513μW / cm 2 Hair a was washed with a commercially available shampoo, rinsed with running water, and then air-dried. After exposure to ultraviolet light, hair a was * a * b * L in color space * , a * and b * was measured using a spectrophotometer "CM-700d" (manufactured by Konica Minolta Japan, Inc.).

[0106] The difference between the values ​​of hair a before dyeing and hair a after dyeing and UV irradiation is ΔL * , Δa * and Δb * Then, the color difference ΔE is calculated using the following formula: * ab was calculated. Color difference ΔE * The higher the ab value, the better the color retention. (Formula)ΔE *ab = {(ΔL * ) 2 +(Δa * ) 2 +(Δb * ) 2} 1 / 2

[0107] Tables I and II show the composition and evaluation results of each cosmetic composition. In the composition of Tables I and II, "-" indicates that the corresponding component is not contained. In addition, in the hair cuticle evaluation in Tables I and II, only Examples 1 to 5 and Comparative Examples 2 and 4 were observed. Comparative Examples 1 and 3 were not observed.

[0108] [Table 1]

[0109] [Table 2]

[0110] From the examples and comparative examples, it can be seen that by using the cosmetic composition of the present embodiment, peeling of the hair cuticle is reduced, and the hair feels smoother. It can also be seen that the color retention of dyed hair is improved. Furthermore, it can be seen that stickiness is suppressed.

[0111] A comparison between Example 1 and Comparative Example 2 shows that the fermented almond product contains components that reduce damage caused by ultraviolet rays and suppress stickiness, while non-fermented almond oil does not contain components with these functions.

[0112] Comparison of Example 1, Comparative Example 1, and Comparative Example 3 shows that the fermented almond product suppresses stickiness. On the other hand, shea butter and VP / eicosene copolymer, which are conventionally used in cosmetics, are found to cause relatively stickiness.

[0113] A comparison between Example 1 and Comparative Example 4 reveals that the fermented almond product contains ingredients that reduce damage caused by ultraviolet rays and suppress stickiness. On the other hand, ethylhexyl methoxycinnamate, a UV absorber that has been conventionally used in cosmetics, has the function of improving color retention, but is also known to cause stickiness.

[0114] Furthermore, a comparison between Example 1 and Example 3 shows that the cosmetic composition of the present embodiment further contains shea butter, thereby improving color retention.
