Description

[Technical Field]

[0001] This invention relates to modified starch, C 13 ~C 15 This invention relates to a composition comprising a combination of fatty acids and clay, and to the use of the composition. [Background technology]

[0002] The use of clay, a mineral, as a medicinal and cosmetic tool has long been popular.

[0003] Clay is used to absorb excess oil, dirt, and toxins from the skin while simultaneously exfoliating and improving skin circulation. Some clays, such as bentonite clay, are primarily consumed for medicinal purposes, such as detoxification or addressing mineral deficiencies.

[0004] Other clays, such as French green clay and Rasoul clay, are used topically for skin conditions and cosmetic purposes. Clays exist in a variety of colors, including red, green, white, and gray, and can have a wide range of textures, from coarse and heavy to fine and fluffy. The various colors of clays result from their natural mineral content.

[0005] In modern cosmetics, such clays are used as an important active ingredient in oil-controlling products and are sold in the form of oil-controlling facial cleansers, etc. Some rinse-off cosmetic compositions also contain clay.

[0006] Rinse-off cosmetic compositions containing clay can retain the clay on keratinous substances such as skin even after being washed off. Any remaining clay residue, if present, can contribute to oil control.

[0007] On the other hand, compositions containing clay may be unstable and therefore may undergo phase separation. [Prior art documents] [Patent Documents]

[0025] The composition according to the present invention may be a cosmetic composition, preferably a rinse-off composition, and more preferably a rinse-off cleansing composition.

[0026] The present invention also relates to a cosmetic method for keratinous substances such as skin, comprising the step of applying a composition according to any one of claims 1 to 12 onto the keratinous substance.

[0029] As a result of diligent research, the inventors have discovered that it is possible to provide a stable composition that can be washed off from keratinous substances such as skin, and that maintains enhanced adhesion of clay to keratinous substances even after the composition has been washed off.

[0030] The composition according to the present invention comprises (a) at least one modified starch and (b) at least one C 13 ~C 15 (c) A combination of fatty acids and at least one type of clay.

[0031] The composition according to the present invention is stable so as not to undergo phase separation over a long period of time.

[0032] The composition according to the present invention can be washed off from keratinous substances such as skin, and after washing off the composition from the keratinous substance, an increased amount of clay can remain attached to the keratinous substance.

[0033] Clay deposits can contribute to oil control. Since the composition according to the present invention can increase the amount of clay adhering to keratinous substances such as skin, it can provide a long-lasting oil control effect. Therefore, for example, the composition according to the present invention can control or suppress undesirable phenomena such as a greasy appearance caused by oily substances such as sebum on keratinous substances such as skin for an extended period. Furthermore, the increased amount of clay adhering to keratinous substances such as skin can provide a smooth feel for an extended period.

[0034] (c) Clay contains (a) modified starch and (b) C 13 ~C 15 They may be coated with fatty acids. (a) Modified starch and (b) C 13 ~C 15 Fatty acids can form complexes. Therefore, (c) clay is (a) modified starch and (b) C 13 ~C 15The material may be coated with a complex formed by fatty acids. Preferably, the complex is formed by hydrophobic modified starch and myristic acid.

[0035] (c) The hydrophobicity of clay is due to (a) modified starch and (b) C 13 ~C 15 Fatty acids, preferably (a) modified starch and (b) C 13 ~C 15 The clay can be reinforced with complexes formed by fatty acids, more preferably with complexes formed by hydrophobic modified starch and myristic acid. Thus, (c) clay can adhere more to keratinous materials such as skin due to hydrophobic-hydrophobic interactions between (c) clay and keratinous materials. This can consequently increase the amount of (c) clay that adheres to keratinous materials.

[0036] The present invention will now be described in detail.

[0037] [Composition] One aspect of the present invention is (a) at least one type of modified starch, (b) at least one type C 13 ~C 15 Fatty acids and, (c) at least one type of clay and It is a composition containing [the specified ingredient].

[0038] In one embodiment of the present invention, The amount of (a) modified starch in the composition is 0.01% to 15% by mass, preferably 0.1% to 10% by mass, and more preferably 0.5% to 5% by mass, relative to the total mass of the composition. (b)C 13 ~C 15 The amount of fatty acids is 1% to 20% by mass, preferably 3% to 15% by mass, and more preferably 5% to 10% by mass, relative to the total mass of the composition. (c) The amount of clay is 1% to 40% by mass, preferably 5% to 35% by mass, and more preferably 10% to 30% by mass, relative to the total mass of the composition.

[0039] (Modified starch) The composition according to the present invention comprises (a) at least one modified starch. A single type of modified starch may be used, or two or more different types of modified starches may be used in combination.

[0040] (a) Modified starch may be in the form of a powder. In other words, (a) modified starch may be in the form of particles. In this case, the particle size of (a) modified starch is not limited.

[0041] (a) Modified starch is film-forming, that is, it can form a film.

[0042] (a) Modified starches are based on base starches. When used herein, base starches are derived from any natural source and are intended to contain all starches suitable for use herein. When used herein, natural starches are those found in nature. More preferably are plant-derived starches obtained by standard breeding techniques, including crossbreeding, transposition, translocation, and transformation, or by any other method of genetic engineering or chromosome engineering to include such modifications. In addition, starches derived from plants grown from artificial mutants and varieties of the above-mentioned common starches, which can be produced by the known standard method of mutagenesis, are also preferred herein.

[0043] Typical starch sources are cereals, tubers, roots, legumes, and fruits. Natural sources may include maize, peas, potatoes, sweet potatoes, bananas, barley, wheat, rice, oats, sago, amaranth, tapioca (cassava), arrowroot, canna, and waxy varieties of sorghum, as well as their low-amylose and high-amylose varieties. In this specification, the term "low-amylose" starch is intended to include starch containing about 10% by mass or less, particularly 5% by mass or less, and more specifically 2% by mass or less of amylose. In this specification, the term "high-amylose" starch is intended to include starch containing at least about 50% by mass, particularly at least about 70% by mass, and more specifically at least about 80% by mass of amylose. High-amylose starch may also be preferred.

[0044] (a) The modified starch may be gelatinized. Gelatinization and techniques for achieving it are publicly known in the art and are disclosed, for example, in U.S. Patents 4,465,702, 5,037,929, 5,131,953 and 5,149,799. See also Chapter XXII, “Production and Use of Pregelatinized Starch,” Starch: Chemistry and Technology, Vol. III, Industrial Aspects, RL Whistler and EF Paschall, Editors, Academic Press, New York, 1967. The term gelatinization is intended to mean swollen starch particles in which birefringence and / or Maltese cross image in polarized light have been lost. Such gelatinized starch derivatives are substantially soluble in cold water without heating. In this regard, “soluble” does not necessarily mean the formation of a true molecular solution and may also mean a colloidal dispersion. In one embodiment, the starch is completely gelatinized.

[0045] Pregelatinized starch can be easily and quickly dissolved even in cold water.

[0046] Gelatinization can be achieved by methods including, but not limited to, drum drying, extrusion, and spray drying. In one embodiment, extrusion is used to simultaneously heat-cook and dry the starch (see, for example, U.S. Patent No. 3,137,592). This method utilizes the physical treatment of the starch / water mixture under high temperature and pressure that results in starch gelatinization, followed by expansion after exiting the nozzle due to the rapid evaporation of water.

[0047] In one embodiment, gelatinization is completed to obtain good solubility and remove undissolved particles that may give the composition an unpleasant gritty texture.

[0048] In one embodiment, the starch is mostly in the form of starch granules. An aqueous dispersion of a pregelatinized starch derivative having mostly the form of granular structure typically has a more uniform and smoother texture than an aqueous dispersion of starch without a granular structure, which may have a slightly rougher feel. In the case of pregelatinized starch with a granular structure, the natural internal structure of hydrogen bonds is broken, but the external shape or form is maintained.

[0049] (a) Modified starch may be crosslinked. Crosslinking of starch chains can be achieved by suitable crosslinking agents, i.e., bifunctional compounds. In one embodiment, the crosslinking method used is a phosphorylation reaction in which starch is reacted with phosphorus oxychloride, phosphorus pentoxide, and / or sodium trimetaphosphate. Two starch chains are crosslinked by an anionic PO group. The anionic properties of the crosslinking site help stabilize the emulsion of starch used according to the present invention. In another embodiment, the crosslinking method is C4-C8 alkanedicarboxylic acids, not limited to C4-C8, exemplified by adipic acid. 18The crosslinking is based on an alkane or alkenedicarboxylic acid. The alkane or alkenedicarboxylic acid links two starch chains via an ester bond. This can be in a linear or branched chain form. Derivatives can be obtained, for example, by reacting starch with a mixed anhydride of dicarboxylic acid and acetic acid. In one embodiment, less than 0.1% by mass of the crosslinking agent is used based on dry starch. In another embodiment, about 0.06 to 0.1% by mass of the crosslinking agent is used based on dry starch.

[0050] (a) It is preferable that the modified starch is hydrophobic. (a) It is even more preferable that the surface of the modified starch is hydrophobic.

[0051] The process of making starch hydrophobic is C 1~6 Acyl(acetyl), C 1~6 This can be carried out by grafting hydrophobic functional groups such as hydroxyalkyl (hydroxyethyl or hydroxypropyl), carboxymethyl, or octenyl succinate groups.

[0052] The alkyl portion of the functional group may have 1 to 6 carbon atoms, preferably 2 to 5 carbon atoms, more preferably 3 or 4 carbon atoms.

[0053] (a) The modified starch is preferably hydroxyalkyl modified starch.

[0054] The position of the hydroxyl group bonded to the starch backbone via an alkyl group, for example, 2 to 6 carbon atoms within the alkyl group, is not important and can be in the alpha to omega positions. In a preferred embodiment, the degree of substitution of the hydroxyalkylation is approximately 0.08 to 0.3. The degree of substitution is the average number of substituted OH groups in the starch molecule per anhydrous glucose unit. Hydroxyalkylation of starch can be achieved by reacting natural starch with an alkylene oxide having a suitable number of carbon atoms (including, but not limited to, hydroxypropylation by reacting starch with propylene oxide). Hydroxyalkyl-modified starch may also contain multiple hydroxyl groups per alkyl group.

[0055] Hydroxyalkyl-modified starch can be selected from the group consisting of hydroxyethyl starch, hydroxypropyl starch, hydroxyethyl starch phosphate, hydroxypropyl starch phosphate, and mixtures thereof.

[0056] Methods for preparing hydroxyalkyl-modified starch can be carried out in any order. However, those skilled in the art are expected to understand the advantages of a particular order. For example, since typical hydroxypropylation can destroy some of the crosslinks achieved, hydroxypropylation is typically considered to be carried out before crosslinking with phosphorus oxychloride when crosslinking starch.

[0057] Examples of hydroxyalkyl-modified starches that are preferred for use in the present invention include the following: Hydroxypropyl starch phosphate (pregelatinized corn starch), marketed by Akzo Nobel as Structure ZEA and XL; and Modified (hydroxypropylated, gelatinized, high-amylose) corn starch, marketed as AMAZE by Akzo Nobel.

[0058] The amount of (a) modified starch in the composition according to the present invention may be 0.01% by mass or more, preferably 0.1% by mass or more, more preferably 0.5% by mass or more, and even more preferably 1% by mass or more, based on the total mass of the composition.

[0059] On the other hand, the amount of (a) modified starch in the composition according to the present invention can be 15% by mass or less, preferably 10% by mass or less, more preferably 5% by mass or less, and even more preferably 3% by mass or less, based on the total mass of the composition.

[0060] The amount of (a) modified starch in the composition according to the present invention may be in the range of 0.01% to 15% by mass, preferably 0.1% to 10% by mass, more preferably 0.5% to 5% by mass, and even more preferably 1% to 3% by mass, based on the total mass of the composition.

[0061] (C 13 ~C 15 fatty acid) The composition according to the present invention includes (b) at least one C 13 ~C 15 Contains fatty acids. Single type C 13 ~C 15 Fatty acids may be used, but two or more different types of C 13 ~C 15 Fatty acids may be used in combination.

[0062] (b)C 13 ~C 15 Fatty acids are preferably saturated. Saturated C 13 ~C 15 The fatty acid can be selected from the group consisting of tridecyl acid (tridecanoic acid), myristic acid (tetradecanoic acid), and pentadecyl acid (pentadecanoic acid).

[0063] (b)C 13 ~C 15 Fatty acids can be unsaturated. 13 ~C 15The fatty acid can be selected from the group consisting of tridecenoic acid, myristoleic acid (tetradecenoic acid), and pentadecenoic acid.

[0064] (b)C 13 ~C 15 The fatty acid is more preferably myristic acid.

[0065] (b)C in the composition according to the present invention 13 ~C 15 The amount of fatty acids can be 1% by mass or more, preferably 3% by mass or more, more preferably 5% by mass or more, and even more preferably 6% by mass or more, based on the total mass of the composition.

[0066] On the other hand, (b)C in the composition according to the present invention 13 ~C 15 The amount of fatty acids can be 20% by mass or less, preferably 15% by mass or less, more preferably 10% by mass or less, and even more preferably 8% by mass or less, based on the total mass of the composition.

[0067] (b)C in the composition according to the present invention 13 ~C 15 The amount of fatty acids can be in the range of 1% to 20% by mass, preferably 3% to 15% by mass, more preferably 5% to 10% by mass, and even more preferably 6% to 8% by mass, relative to the total mass of the composition.

[0068] (b)C 13 ~C 15 The mass ratio of the amount (mass) of fatty acids to the amount (mass) of modified starch (a) can be 1.1 or higher, preferably 1.2 or higher, and more preferably 1.3 or higher.

[0069] (a) Modified starch and (b) C 13 ~C 15 Fatty acids can form complexes.

[0070] (Clay) The composition according to the present invention comprises (c) at least one type of clay. A single type of clay may be used, or two or more different types of clay may be used in combination.

[0071] The term "clay" refers to a natural material composed primarily of fine-grained minerals, generally plastic with appropriate moisture content, and hardening upon drying or firing. Clay typically contains phyllosilicates, but may also contain other substances that impart plasticity and harden upon drying or firing. Associated phases in clay may include substances that do not impart plasticity and organic matter. A common definition is that from the Penguin Dictionary of Science, namely, "finely fragmented rock material whose constituent minerals are primarily various silicates of magnesium or aluminum." Clay is a type of kaolinite (typically, [Si4]Al4O 10 (OH)8.nH2O (defined as n=0 or 4), illite (typically M x [Si 6.8 Al 1.2 ]Al3Fe .025 Mg .75 O 20 (OH)4 is defined as vermiculite (typically M x [Si7Al]AlFe .05 Mg 0.5 O 20 (OH)4 is defined as smectite (typically M x [Si8]Al 3.2 Fe 0.2 Mg 0.6 O 20 (OH)4 is defined as chlorite (typically (Al(OH) 2.55 )4[Si 6.8 AlO 1.2}Al 3.4 Mg 0.6 ) 20 It includes (defined as (OH)4).

[0072] Another definition frequently used by chemists is "a natural sediment or sedimentary rock composed of one or more minerals and by-compounds, the whole of which is usually rich in hydrated aluminum silicate, iron or magnesium, hydrated alumina, or iron oxide, and which is predominantly of colloidal size or near-colloidal size, and which usually exhibits plasticity when thoroughly ground and moistened" (see Kirk-Othmer, Encyclopaedia of Chemical Technology, Vol. 5, p. 544, 2nd edition, John Wiley and Sons, Inc., New York, NY 1964). An example of clay is described in the book "Clay mineralogy," S. Caillere, S. Henin, M. Rautureau, 2nd edition 1982, Masson. Clay may be of natural or synthetic origin.

[0073] Examples of hydrophilic clays include smectites such as saponite, hectorite, montmorillonite, bentonite, and byderite. Examples of hydrophilic clays include synthetic hectorite (also called laponite) such as products sold by companies under the names Laporte Laponite XLG, Laponite RD, and Laponite RDS (these products are sodium silicate and magnesium silicate, particularly sodium, lithium, and magnesium); bentonite such as products sold under the name Bentone® HC Rheox; aluminum products such as magnesium silicate and hydrated products sold by Vanderbilt Company as ultra Veegum®, Veegum® HS, and Veegum® DGT; and calcium silicate, especially in synthetic form, sold by companies under the name Micro-cel® C.

[0074] Fuller clay is primarily composed of hydrated aluminum silicate, which contains metal ions such as magnesium, sodium, and calcium within its structure. Montmorillonite is the main clay mineral in Fuller clay, but other minerals such as kaolinite, attapulgite, and palygorskite may also be present in its composition.

[0075] Lipophilic clay refers to clay that swells in a lipophilic medium, forming a colloidal dispersion. Examples of lipophilic clay include modified clays such as hectorite (CTFA name: disteardimonium hectorite) modified with ammonium distearyldimethylammonium chloride, sold by Rheox under the name "Bentone 38 CE" or by ELEMENTIS under the name Bentone® 38V, and modified magnesium silicate (Rheox's Bentone gel VS38) hectorite modified with ammonium chloride fatty acids C10-C22.

[0076] Such clays may be derived from natural or synthetic mineral clays such as hectorite, bentonite, and their quaternary derivatives. For example, these can be obtained by reacting minerals with quaternary ammonium compounds such as stearalkonium bentonite, hectorite, quaternary hectorite such as quaternium-18 hectorite, carbonates such as propylene carbonate, bentonite, etc.

[0077] Non-limiting examples of clays that can be used in this invention include: Fulah clay, Pinatubo volcanic ash clay from the Philippines, Aleppo clay from Syria, Pulau tiga volcanic clay from Malaysia, Nha Trang clay from Vietnam, white kaolinite from Korea, yellow clay from Korea, Jeju volcanic clay from Korea, Guanziling clay from Taiwan, Wudalianchi volcanic clay from China, black clay from Yuncheng salt lake in China, mineral clay from Tantou village in China, pottery clay (kaolin), maifan stone from China, Beppu Onsen fango from Japan, kucha from Japan, Tanakura clay from Japan, Cambrian blue clay from Russia, Blue Lagoon clay from Iceland, Saki Lake clay from Ukraine, Karlovy vary wetland clay from the Czech Republic, Heviz Georgikon wetland clay from Hungary, Alpine wetland clay from Austria, Bad wilsnack clay from Germany, Bavarian mineral salt mountain clay from Germany, Freiburg volcanic ash from Germany, Santorini clay from Greece, and Mar from Spain.

[0080] On the other hand, the amount of (c) clay in the composition according to the present invention can be 40% by mass or less, preferably 35% by mass or less, more preferably 30% by mass or less, and even more preferably 25% by mass or less based on the total mass of the composition.

[0081] The amount of (c) clay in the composition according to the present invention can be in the range of 1% to 40% by mass, preferably 5% to 35% by mass, more preferably 10% to 30% by mass, and even more preferably 15% to 25% by mass based on the total mass of the composition.
