Description

[Technical Field]

[0001] The present invention relates to a composition, preferably a cosmetic composition, more preferably a dermocosmetic composition, capable of forming a film. [Background technology]

[0002] In skin care field, one of the objectives is to instantly lighten skin tone, which can be achieved by, for example, scattering light on skin.It is believed that the non-transparent film on skin, for example, semi-transparent film, will scatter light on skin, while the highly transparent film will not scatter light.

[0003] Hyaluronic acid has been widely used in cosmetics in search of moisturizing effects, etc. Hyaluronic acid can form a film on keratinous materials such as skin, etc. However, the film of hyaluronic acid is very transparent, and therefore cannot provide any skin lightening effect.

[0004] On the other hand, polyglutamic acid has been proposed for use in cosmetics in search of moisturizing effects, etc. Polyglutamic acid can also form a film on keratinous materials such as skin, but the film of polyglutamic acid is very transparent and therefore cannot provide any skin lightening effect.

[0023] As a result of extensive research, the present inventors have discovered that it is possible to provide a composition comprising a polyamino acid such as polyglutamic acid or a salt thereof, and a polysaccharide such as hyaluronic acid or a salt thereof, which is capable of forming a film that is not very transparent.

[0024] Thus, one aspect of the present invention is (a) at least one polyamino acid or a salt thereof; (b) at least one polysaccharide; (c) at least one metal salt; (d) at least one surfactant; A composition comprising: (c) the amount of metal salt is greater than 0.01% by weight, preferably 0.05% by weight or more, and more preferably 0.1% by weight or more, based on the total weight of the composition; It is a composition.

[0025] The composition according to the present invention is capable of forming a not very transparent film, preferably a translucent or opaque film, more preferably a translucent film.

[0026] The film formed by the composition according to the present invention is capable of lightening keratinous materials such as the skin.

[0027] When dissolved in water, (b) polysaccharides can provide a thickening effect greater than that of (a) polyamino acids or salts thereof. For example, a 1% by weight aqueous solution of (b) polysaccharides can have a viscosity (at 20°C) that is at least 10 times, preferably 50 times, and more preferably 100 times higher than that of a 1% by weight aqueous solution of (a) polyamino acids or salts thereof. The viscosity can be measured under atmospheric pressure using a viscometer such as a Brookfield viscometer or a rheometer. This viscosity difference can cause viscoelastic phase separation (Phys. Rev. Lett. 1993, 71, 3158), resulting in the formation of a less transparent film.

[0028] The compositions according to the invention are suitable for cosmetic skin treatments such as skin care and skin make-up.

[0029] The compositions according to the present invention may also provide additional benefits.

[0030] (a) Polyamino acids such as polyglutamic acid or salts thereof are water-absorbing and film-forming, and therefore, the composition according to the present invention containing (a) polyamino acids or salts thereof can form a film on keratinous materials such as skin that can provide a moisturizing effect.

[0031] Polysaccharides such as (b) hyaluronic acid and its salts are also water-absorbing and film-forming, and therefore, the composition according to the present invention containing (b) polysaccharides can form a film on keratinous materials such as skin that can provide a moisturizing effect.

[0032] When the composition according to the present invention further comprises (f) water, the composition according to the present invention can also provide good hydration effect and a refreshing feeling.

[0033] The present invention will now be described in more detail.

[0034] [Composition] The composition according to the present invention comprises (a) at least one polyamino acid or a salt thereof; (b) at least one polysaccharide; (c) at least one metal salt; (d) at least one surfactant; Including, (c) The amount of metal salt is greater than 0.01% by weight, preferably 0.05% by weight or more, and more preferably 0.1% by weight or more, based on the total weight of the composition.

[0035] (Polyamino acid or its salt) The composition according to the present invention comprises (a) at least one polyamino acid or a salt thereof. A single type of polyamino acid or a salt thereof may be used, or two or more different types of polyamino acids or salts thereof may be used in combination.

[0036] Preferably, the polyamino acid is selected from polyglutamic acid. Component (a) in the composition according to the invention is therefore preferably at least one polyglutamic acid or a salt thereof.

[0037] Polyglutamic acid or a salt thereof has the following chemical formula (1): ROOC-CH2CH2-CH(-COOR)-NH-[CO-CH2CH2-CH(-COOR)-NH-] n -CO-CH2CH2-CH(-COOR)-NH2(1) (In the formula, R independently represents a hydrogen atom, an alkali metal atom such as a sodium atom or a potassium atom, or an ammonium group such as a tetramethylammonium group or a tetraethylammonium group; n is an integer of 2 or more, preferably 4 or more, and more preferably 6 or more. It may have a chemical structure represented by:

[0038] The polyglutamic acid or a salt thereof represented by the above chemical formula (1) can be called a γ-polyglutamic acid or a salt thereof because the carboxylic acid group at the γ-position and the amino group at the α-position form a peptide bond.

[0039] It may be preferable that the molecular weight of the polyglutamic acid or a salt thereof is 1000 or more and the degree of polymerization is 8 or more ("n" in the above chemical formula (1) is 6 or more).

[0040] It may be more preferable that the molecular weight of the polyglutamic acid or a salt thereof is 100,000 or more and the degree of polymerization is 770 or more ("n" in the above chemical formula (1) is 768 or more).

[0044] Glutamic acid, which is a constituent amino acid of polyglutamic acid or its salts, may be in the D-form, L-form, or racemic form. However, in consideration of commercial availability, biocompatibility, and biodegradability, it may be preferable to use polyglutamic acid composed only of L-form glutamic acid or polyglutamic acid composed of a mixture of L- and D-form glutamic acid. However, polyglutamic acid composed of D-form glutamic acid, which has the same effect but is less degradable, can also be used.

[0045] The method for producing polyglutamic acid or its salts is not particularly limited. Examples include organic synthesis using a peptide synthesizer, organic synthesis by polymerization of glutamate N-carboxylic anhydride, and organic synthesis by polymerization of N-benzyloxycarbonylglutamic anhydride. Microorganisms belonging to the genus Bacillus (particularly Bacillus subtilis, Bacillus anthracis, Bacillus licheniformis, and Bacillus megaterium) capable of producing γ-polyglutamic acid can also be used in fermentation to produce polyglutamic acid or its salts.

[0046] The culture medium used in the fermentation method includes natural culture media consisting of natural products such as shochu distillery wastewater culture media and soybean extract culture media, as well as the following ingredients: carbon sources such as glucose, fructose, galactose, sucrose, maltose, mannose, lactose, glycerol, and starch; inorganic nitrogen sources such as ammonium sulfate, ammonium phosphate, and ammonium chloride; an organic nitrogen source such as glutamic acid or a salt thereof, or aspartic acid or a salt thereof; Major inorganic salts such as sodium chloride, magnesium sulfate, monopotassium phosphate, phosphorus and disodium hydrogen phosphate, trace amounts of inorganic salts containing atoms such as iron, copper, zinc, cobalt, nickel, boron, manganese, molybdenum, tin, selenium, silicon, arsenic, vanadium, chromium, and fluorine; Vitamins such as biotin, nicotinamide, calcium pantothenate, thiamine, riboflavin, and pyridoxine hydrochloride; organic acids such as citric acid, tartaric acid, malic acid, and glycolic acid; Natural product extracts such as yeast extract, meat extract, potato extract, tomato extract, and soybean peptides Any synthetic or semi-synthetic medium consisting of any one of the above may be used at any concentration.

[0047] The culture conditions for the microorganisms may be set in the range of 20° C. to 37° C. and may be further controlled during the microbial growth process and the polyglutamic acid production process, and the pH may be set in the range of 5.0 to 8.0 and may be further controlled during the microbial growth process and the polyglutamic acid production process.

[0048] After the cultivation is completed, polyglutamic acid or a salt thereof can be extracted from the culture medium and purified by any known method such as acid precipitation, solvent precipitation, or membrane purification.

[0049] As polyglutamic acid or a salt thereof, it is preferable to use polyglutamic acid or an alkali metal salt thereof, such as sodium polyglutamate.

[0050] Commercially available products may be used as polyglutamic acid or a salt thereof. Examples of polyglutamic acid or a salt thereof include Hyafactor™ PGA-HM sold by Bloomage Biotechnology Co., Ltd. in China, and Bio-PGA Solution HE, HB, LB, and LE, as well as Bio PGA Na powder sold by Ichimaru Pharcos Co., Ltd. in Japan.

[0051] The amount of (a) polyamino acid or a salt thereof in the composition according to the present invention may be 0.01% by mass or more, preferably 0.05% by mass or more, more preferably 0.1% by mass or more, relative to the total mass of the composition.

[0052] On the other hand, the amount of (a) polyamino acid or a salt thereof in the composition according to the present invention may be 5% by mass or less, preferably 3% by mass or less, more preferably 1% by mass or less, relative to the total mass of the composition.

[0053] Therefore, the amount of (a) polyamino acid or a salt thereof in the composition according to the present invention may be in the range of 0.01% by mass to 5% by mass, preferably 0.05% by mass to 3% by mass, and more preferably 0.01% by mass to 1% by mass, relative to the total mass of the composition.

[0054] (polysaccharide) The composition according to the present invention comprises (b) at least one polysaccharide. A single type of polysaccharide may be used, or two or more different types of polysaccharides may be used in combination.

[0055] (b) The polysaccharide may be selected from any conventional polysaccharide used in the cosmetic field.

[0056] (b) It may be preferred that the polysaccharide is selected from linear polysaccharides.

[0057] The term "linear" as used herein in reference to a polysaccharide means that the polysaccharide does not have side chains or branches containing at least one saccharide. In other words, each monosaccharide unit in a linear polysaccharide chain contains only one or two glycosidic bonds.

[0058] Examples of such linear polysaccharides include gellan gum, alginic acid and its salts, such as sodium alginate, pectin, carrageenans, such as κ-carrageenan, linear dextrin, mucopolysaccharides (glycosaminoglycans), such as hyaluronic acid and chondroitin sulfate, cellulose and its derivatives, such as carboxymethylcellulose, hydroxyethylcellulose, and hydroxypropylmethylcellulose.

[0059] In a preferred embodiment, (b) the polysaccharide may be selected from the group consisting of hyaluronic acid, hyaluronic acid salts, hyaluronic acid derivatives, hyaluronic acid derivative salts, and mixtures thereof (referred to as the "hyaluronic acid component").

[0060] Hyaluronic acid is the predominant glycosaminoglycan found in the skin. Therefore, fibroblasts predominantly synthesize collagen, non-collagenous matrix glycoproteins (fibronectin, laminin), proteoglycans, and elastin. Keratinocytes, for their part, predominantly synthesize sulfated glycosaminoglycans and hyaluronic acid. Hyaluronic acid is also called hyaluronan.

[0061] Hyaluronic acid exists in free state in epidermis and dermis, and it is responsible for the turgor of skin.This polysaccharide can actually hold a large volume of water, up to 1000 times its mass.In this sense, hyaluronic acid plays an important role in increasing the amount of water bound in tissue, and also in the mechanical properties and wrinkle formation of skin.

[0062] Hyaluronic acid can be represented by the following chemical formula:

[0063] [ka]

[0064] In the context of the present invention, the term "hyaluronic acid" specifically refers to a compound of the formula:

[0065] [ka]

[0068] The term "hyaluronic acid," in the context of the present invention, includes linear polymers comprising the above-listed polymer units linked together in a chain via alternating β(1,4) and β(1,3) glycosidic bonds, with molecular weights (Mw) that can range between 380 and 13,000,000 daltons, which depends primarily on the source from which the hyaluronic acid is obtained and / or the method of preparation.

[0069] The term "hyaluronic acid" in the context of the present invention also includes hydrolyzed hyaluronic acid.

[0070] The term "hyaluronic acid derivatives" in the context of the present invention includes hyaluronic acid esters, in particular those in which all or part of the carboxylic acid groups of the acid function are esterified with oxyethylenated alkyls or alcohols containing 1 to 20 carbon atoms, in particular those in which the degree of substitution at the level of D-glucuronic acid of hyaluronic acid ranges from 0.5 to 50%.

[0071] Mention may in particular be made of the methyl, ethyl, n-propyl, n-pentyl, benzyl and dodecyl esters of hyaluronic acid, which are described in detail in D. Campoccia et al., "Semisynthetic resorbable materials from hyaluronan esterification", Biomaterials 19 (1998) pp. 2101-2127.

[0072] In one embodiment, the hyaluronic acid derivative may be, for example, acetylated hyaluronic acid.

[0073] The term "hyaluronic acid derivatives" in the context of the present invention also includes cationic hyaluronic acid.

[0074] Cationic hyaluronic acid contains at least one cationic moiety. The cationic moiety is -N + The cationic moiety may be a trialkylammonium group such as (CH3)3. The cationic moiety may contain at least one hydroxyl group. An example of a cationic group is -CH2-CH(OH)-CH2-N + (CH3)3 is an example.

[0075] An example of a cationic hyaluronic acid is hydroxypropyltrimonium hyaluronate.

[0076] Hyaluronic acid salts or hyaluronic acid derivative salts include alkali metal salts such as sodium salts and potassium salts, alkaline earth metal salts such as magnesium salts, ammonium salts, and mixtures thereof.

[0077] The molecular weight of the hyaluronic acid component selected from the group consisting of hyaluronic acid, hyaluronic acid salts, hyaluronic acid derivatives, hyaluronic acid derivative salts, and mixtures thereof is not limited. The molecular weight of the hyaluronic acid component may be 5 kDa or more, preferably 20 kDa or more, and more preferably 100 kDa or more. The molecular weight of the hyaluronic acid component may be 20 MDa or less, preferably 10 MDa or less, and more preferably 2,000 kDa or less. Therefore, the molecular weight of the (b) hyaluronic acid component may be 5 kDa to 20 MDa, preferably 20 kDa to 10 MDa, and more preferably 100 kDa to 2,000 kDa.

[0078] Unless otherwise defined in the description, "molecular weight" may mean weight average molecular weight.

[0079] The hyaluronic acid component may specifically be hyaluronic acid supplied by Centipro under the trade name HyActive™ (MW: 10-150 kDa), by Givaudan under the trade name Cristalhyal™ (registered trademark) (MW: 1-1.4 MDa), by Bioland under the trade name Nutra™ HA (MW: 907,600 Da), by Bioland under the trade name Nutra™ HAF (MW: 74,600 Da), by Bioland under the trade name Oligo™ HA (MW: 0.5-10.1 kDa), by Res Pharma under the trade name D-Factor™ (registered trademark) (MW: 380 Da), or by Bloomage Freda Biopharm under the trade name Hybloom™ Sodium Hyaluronate (HA-T) (MW: 1,000 kDa-1,800 kDa).

[0080] A single hyaluronic acid component having a single molecular weight or a combination of two or more hyaluronic acid components having different molecular weights may be used as the hyaluronic acid component.

[0081] (b) The polysaccharide is preferably selected from hyaluronates, more preferably alkali metal hyaluronates, and even more preferably sodium hyaluronate.

[0082] The amount of (b) polysaccharide in the composition according to the present invention may be 0.01% by mass or more, preferably 0.05% by mass or more, more preferably 0.1% by mass or more, relative to the total mass of the composition.

[0084] Therefore, the amount of (b) polysaccharide in the composition according to the present invention may be in the range of 0.01% by mass to 5% by mass, preferably 0.05% by mass to 3% by mass, and more preferably 0.1% by mass to 1% by mass, relative to the total mass of the composition.

[0085] (metal salts) The composition according to the present invention comprises (c) at least one metal salt. A single type of metal salt may be used, or two or more different types of metal salts may be used in combination.

[0233] (Examples 1 to 6 and Comparative Examples 1 to 4) [Preparation] The following compositions according to Examples 1 to 6 and Comparative Examples 1 to 4 shown in Table 1 were prepared by mixing the components shown in Table 1. All numerical values ​​for the amounts of components shown in Table 1 are based on "mass %" of the active ingredient. Symbols (a) to (f) in Table 1 correspond to components (a) to (f).

[0234] [Table 1]

[0235] [evaluation] (Transparency of the film) Each of the compositions according to Examples 1 to 6 and Comparative Examples 1 to 4 was cast onto a glass substrate and dried at room temperature (25°C) to prepare a film. The transparency of the prepared film was visually evaluated according to the following criteria, where the transparency of the film prepared from the composition according to Example 1 was set as the reference or standard. 5: Not transparent (very opaque) 4: Less transparent than the reference (no transparency) 3: Referential (no transparency) 2: More transparent than the reference (less transparent) 1: Highly transparent (very transparent)

[0236] The results are shown in Table 1.

[0237] (Summary) The compositions according to Examples 1 to 6 were capable of preparing less transparent films (eg, the films were translucent) and were capable of lightening keratinous materials such as skin.
