[0003] To date, some prior art has reported cosmetic foaming cleansing products. For example, JP-A-2020-180062 discloses a cosmetic foaming cleansing product comprising (a) at least one modified starch and (b) at least one C 13 ~C 15 Disclosed is a composition comprising a fatty acid and (c) at least one clay, which is stable and can be rinsed off of the skin and leaves behind an enhanced deposition of clay on the skin after the composition is rinsed off of the skin.

[0004] In addition, JP-A-2022-95240 discloses a method for producing a starch composition comprising (a) at least one modified starch and (b) at least one C 13 ~C 15 Disclosed is a composition comprising: (a) a fatty acid; (c) at least one clay; and (d) at least one amphoteric surfactant, the composition being capable of being rinsed from keratinous materials, such as skin, and leaving behind an enhanced deposition of clay on the keratinous materials after the composition is rinsed from the skin.

[0005] However, there remains a need to enhance the lathering properties of cosmetic rinse-off compositions. [Prior art documents] [Patent documents]

[0024] After extensive investigation, the inventors have discovered that it is possible to provide a composition having improved foaming properties in terms of ease of foaming and foam volume, thus completing the invention.

[0025] The composition according to the invention comprises (a) at least one modified starch and (b) at least one C 13 ~C 15 (c) at least one powdered organic salt; and (d) water.

[0026] Hereinafter, the present invention will be described in detail.

[0027] [Composition] One aspect of the present invention is (a) at least one modified starch; (b) at least one C 13 ~C 15 Fatty acids, (c) at least one powdered organic salt; (d) Water and The composition comprises:

[0028] Each of these components will be described in more detail below.

[0029] (modified starch) The composition according to the 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.

[0030] The (a) modified starch may be in the form of a powder. In other words, the (a) modified starch may be in the form of particles. In this case, the particle size of the (a) modified starch is not limited.

[0031] (a) It is preferred that the modified starch is film-forming, i.e. capable of forming a film.

[0032] (a) Modified starch is based on base starch. Base starch, as used herein, is intended to include all starches derived from any natural source, any of which may be suitable for use herein. Native starch, as used herein, is as it is found in nature. Also suitable are starches derived from plants obtained by standard breeding techniques, including cross-breeding, transposition, transposition, transformation, or by any other method of genetic or chromosomal engineering to include their variants. In addition, starches derived from plants bred from artificial mutants and variants of the above common starches, which may be produced by known standard methods of mutation breeding, are also suitable herein.

[0033] Typical starch sources are cereals, tubers, roots, legumes and fruits. Natural sources can be corn (maize), peas, potatoes, sweet potatoes, bananas, barley, wheat, rice, oats, sago, amaranth, tapioca (cassava), arrowroot, canna and waxy varieties of sorghum, as well as low and high amylose varieties thereof. As used herein, the term "low amylose" starch is intended to include starches containing about 10% or less by weight, particularly 5% or less by weight, more particularly 2% or less by weight of amylose. As used herein, the term "high amylose" starch is intended to include starches containing at least about 50% by weight, particularly at least about 70% by weight, more particularly at least about 80% by weight of amylose. High amylose starches may be preferred.

[0034] (a) The modified starch may be pregelatinized. Pregelatinization and techniques for achieving pregelatinization are known in the art and are disclosed, for example, in U.S. Pat. Nos. 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, R.L. Whistler and E.F. Paschall, Editors, Academic Press, New York 1967. The term "pregelatinized" is intended to mean swollen starch particles that have lost their birefringence and / or Maltese cross in polarized light. Such pregelatinized starch derivatives are substantially soluble in cold water without cooking. In this context, "soluble" does not necessarily mean the formation of a true molecular solution, but may also mean a colloidal dispersion. In one embodiment, the starch is fully pregelatinized.

[0035] Pregelatinized modified starch can be easily and quickly solubilized even in cold water.

[0036] Pregelatinization can be achieved by methods including, but not limited to, drum drying, extrusion and spray drying. In one embodiment, the extrusion method is used to simultaneously cook and dry the starch (see, for example, US Pat. No. 3,137,592). This method utilizes the physical treatment of a starch / water mixture at high temperature and pressure, which results in gelatinization of the starch, followed by expansion after exiting a nozzle with the rapid evaporation of the water.

[0037] In one embodiment, the gelatinization is completed to obtain good solubility and to remove undissolved particles that may result in an unpleasant gritty feel in the composition.

[0038] In one embodiment, the starch has mostly intact starch granules. Aqueous dispersions of pregelatinized starch derivatives with mostly intact granular structure typically have a more uniform and smoother texture than aqueous dispersions of starches that do not have a granular structure, which may have a slightly grainy feel. In the case of pregelatinized starches with intact granular structure, the native internal structure of hydrogen bonds is disrupted, but the outer shape or morphology is maintained.

[0039] (a) The modified starch may be crosslinked. Crosslinking of the 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 the starch is reacted with phosphorus oxychloride, phosphorus pentoxide and / or sodium trimetaphosphate. Two starch chains are crosslinked by an anionic PO group. The anionic character of the crosslinking sites aids in the emulsion stabilizing action of the starch used according to the invention. In another embodiment, the crosslinking method is by the addition of C4-C8 alkanedicarboxylic acids, including but not limited to C4-C8 alkanedicarboxylic acids, exemplified by adipic acid. 18The cross-linking agent is selected from the group consisting of alkane or alkene dicarboxylic acids, which link two starch chains together via an ester bond. This can be in the form of a linear or branched chain. The derivatives can be obtained, for example, by reacting starch with a mixed anhydride of a dicarboxylic acid and of acetic acid. In one embodiment, less than 0.1% by weight of cross-linking agent is used, based on dry starch. In another embodiment, about 0.06-0.1% by weight of cross-linking agent is used, based on dry starch.

[0040] (a) It is preferred that the modified starch is hydrophobic. It is more preferred that the surface of the (a) modified starch is hydrophobic.

[0041] The modification of starch to make it hydrophobic is C 1~6 Acyl (acetyl), C 1~6 This can be achieved by grafting hydrophobic functional groups such as hydroxyalkyl (hydroxyethyl or hydroxypropyl), carboxymethyl or octenylsuccinic groups.

[0042] The alkyl portion of the functional group may have from 1 to 6 carbon atoms, preferably from 2 to 5 carbon atoms, and more preferably 3 or 4 carbon atoms.

[0043] (a) It is preferred that the modified starch is a hydroxyalkyl modified starch.

[0044] The position of the hydroxyl group attached to the starch backbone through the alkyl group, such as 2-6 carbon atoms in the alkyl group, is not critical and can be in the alpha to omega positions. In a preferred embodiment, the degree of substitution of the hydroxyalkylation is about 0.08-0.3. The degree of substitution is the average number of substituted OH groups of the starch molecule per anhydroglucose unit. Hydroxyalkylation of starch can be effected by reacting native starch with an alkylene oxide having an appropriate 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.

[0045] The hydroxyalkyl modified starch may be selected from the group consisting of hydroxyethyl starch, hydroxypropyl starch, hydroxyethyl starch phosphate, hydroxypropyl starch phosphate, and mixtures thereof.

[0046] The method of preparing hydroxyalkyl modified starch can be carried out in any order. However, a person skilled in the art will understand the advantages of a certain order. For example, hydroxypropylation will typically be carried out before cross-linking with phosphorus oxychloride when the starch is cross-linked, because the typical hydroxypropylation process will destroy some of the cross-linking that has been achieved.

[0047] Examples of hydroxyalkyl modified starches preferably used in the present invention include: Hydroxypropyl starch phosphate (pregelatinized maize starch), available as Structure ZEA and XL from Akzo Nobel; and A modified corn starch (hydroxypropylated, pregelatinized, high amylose) marketed as AMAZE by Nouryon.

[0048] The amount of (a) modified starch in the composition according to the present invention may be 0.01% by weight or more, preferably 0.1% by weight or more, more preferably 0.5% by weight or more, and even more preferably 1% by weight or more, relative to the total weight of the composition.

[0049] On the other hand, the amount of (a) modified starch in the composition according to the present invention may 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, relative to the total mass of the composition.

[0050] The amount of (a) modified starch in the composition according to the present invention may be in the range of 0.01% by mass to 15% by mass, preferably 0.1 to 10% by mass, more preferably 0.5% by mass to 5% by mass, and even more preferably 1% by mass to 3% by mass, relative to the total mass of the composition.

[0051] In the context of this specification, any combination of the above upper and lower limits can be used to express a preferred range of amounts.

[0058] (b) C in the composition according to the present invention 13 ~C 15 The amount of fatty acid may be in the range of 1% to 20% by mass, preferably 2% to 15% by mass, more preferably 3% to 10% by mass, and even more preferably 4% to 8% by mass, relative to the total mass of the composition.

[0059] (b)C 13 ~C 15 The mass ratio of the amount (mass) of fatty acid / the amount (mass) of (a) modified starch may be 1.0 or more, preferably 2.0 or more, more preferably 3.0 or more, and even more preferably 4.0 or more.

[0060] (a) Modified starch and (b) C 13 ~C 15 It can form complexes with fatty acids.

[0061] (Powdered organic salt) The composition according to the invention comprises (c) at least one powdered organic salt. A single type of powdered organic salt may be used, or two or more different types of powdered organic salts may be used in combination.

[0062] (c) Powdered organic salts can serve to enhance the lathering characteristics of the compositions of the present invention.

[0063] Without being bound by theory, it is believed that (c) the powdered organic salt may disrupt the water-based composition network, which makes the composition more likely to fuse with water when the composition comes into contact with water. This function of the powdered organic salt may result in imparting the composition with better foaming properties, particularly ease of foaming.

[0064] The term "powder" as used herein should be understood to mean particles of any shape that are insoluble in the medium of the composition, particularly water.

[0065] (c) Powdered organic salts may be of any shape, regardless of the crystallographic morphology (e.g. lamellar, cubic, hexagonal, orthorhombic, etc.), and may be platelet-shaped, spherical or oblong.

For example, the average particle size of the (c) powdered organic salt may be 50 μm or less, preferably 20 μm or less, more preferably 10 μm or less. The average particle size of the powdered organic salt may be 0.01 μm or more, preferably 0.1 μm or more. The term "average particle size" as used herein refers to the number average particle size given by statistical particle size distribution for half of the population, and is referred to as D50. For example, the number average particle size can be measured with a laser diffraction particle size distribution analyzer, such as the Mastersizer 2000 by Malvern Corp.

[0067] (c) The powdered organic salt may be water-insoluble.

[0068] The term "water-insoluble" as used herein means water-insoluble at room temperature (25°C) and atmospheric pressure (10 5 This term refers to substances that are soluble in water at a concentration of less than 0.1% by weight, specifically less than 0.01% by weight, based on the total weight of water (at 1000 Pa).

[0069] The cationic portion of the powdered organic salt can be selected from metal cations and organic cations. Preferably, the cationic portion of the powdered organic salt is selected from metal cations. Thus, (c) the powdered organic salt is preferably a powdered organometallic salt.

In the case of pregelatinized starches with intact granular structure, the native internal structure of hydrogen bonds is disrupted, but the outer shape or morphology is maintained.

[0089] The modified starch may be cross-linked. Cross-linking of the starch chains can be achieved by suitable cross-linking agents, i.e. bifunctional compounds. In one embodiment, the cross-linking method used is a phosphorylation reaction in which the starch is reacted with phosphorus oxychloride, phosphorus pentoxide and / or sodium trimetaphosphate. Two starch chains are cross-linked by an anionic PO group. The anionic character of the cross-linking sites aids in the emulsion stabilizing action of the starch used according to the invention. In another embodiment, the cross-linking method is the use of C4-C8 alkanedicarboxylic acids, including but not limited to C4-C8 alkanedicarboxylic acids, exemplified by adipic acid. 18 The cross-linking agent is selected from the group consisting of alkane or alkene dicarboxylic acids, which link two starch chains together via an ester bond.

[0103] (Other ingredients) - Clay The composition according to the invention may comprise at least one clay. A single type of clay may be used or two or more different types of clay may be used in combination.

[0104] The term "clay" refers to a naturally occurring material composed primarily of fine-grained minerals, which is generally plastic at the appropriate moisture content and hardens when dried or fired. Clays usually contain phyllosilicates, but clays may also contain other materials that impart plasticity and harden when dried or fired. Associated phases in clays may include materials that do not impart plasticity and organic matter. A common definition is that given in the Penguin Dictionary of Science: "a finely divided rock material whose constituent minerals are mainly various silicates of magnesium or aluminum." Clays are classified as kaolinite (typically [Si4]Al4O 10 (OH)8.nH2O (n = 0 or 4), illite (typically Mx[Si 6.8 Al 1.2 ]Al3Fe. 025 Mg. 75 O 20 (OH)4), vermiculite (typically M x [Si7Al]AlFe. 05 Mg 0.5 O 20 (OH)4), smectites (typically M x [Si8]Al 3.2 Fe 0.2 Mg 0.6 O 20 (OH)4), chlorite (typically (Al(OH) 2.55 )4[Si 6.8 AlO 1.2}Al 3.4 Mg 0.6 ) 20 (OH)4), and phyllosilicate minerals or talc (typically Mg3SiO4O 10 (defined as (OH)2).

[0105] Another definition often used by chemists is "a naturally occurring deposit or sedimentary rock composed of one or more minerals and accessory compounds, generally rich in hydrated aluminum silicates, iron or magnesium, hydrated alumina, or iron oxide, consisting mainly of particles of colloidal or near-colloidal size, and usually exhibiting plasticity when thoroughly crushed and moistened" (see Kirk-Othmer, Encyclopaedia of Chemical Technology, Vol. 5, p. 544, 2nd ed., John Wiley and Sons, Inc., New York, NY 1964). Examples of clays are given in the book "Clay mineralogy", S. Caillere, S. Henin, M. Rautureau, 2nd ed., 1982, Masson. Clays may be of natural or synthetic origin.

[0106] Hydrophilic clays include smectites, such as saponite, hectorite, montmorillonite, bentonite, beidellite.Hydrophilic clays include synthetic hectorites (also called laponites), such as the products sold by companies under the names Laporte Laponite XLG, Laponite RD, Laponite RDS (these products are sodium and magnesium silicates, especially sodium, lithium and magnesium), bentonites, such as the products sold under the name Bentone® HC Rheox, magnesium and aluminum silicate products, such as the hydrated products sold by Vanderbilt Company under the names ultra Veegum®, Veegum® HS, Veegum® DGT, or calcium silicate, especially the synthetic form sold by companies under the name Micro-Cel® C.

[0107] Fuller's earth consists primarily of hydrated aluminum silicates that contain metal ions such as magnesium, sodium and calcium within their structure. Montmorillonite is the predominant clay mineral in Fuller's earth, but it may contain other minerals such as kaolinite, attapulgite and palygorskite, among other components.

[0108] Organophilic clays are understood to mean clays that swell in an oleophilic medium, forming a colloidal dispersion by swelling. Organophilic clays include ammonium chloride fatty acid C hectorite, such as hectorite modified with ammonium distearyldimethylammonium chloride (CTFA name: disteardimonium hectorite), sold under the name "Bentone 38 CE" by the company Rheox, or Bentone® 38V by the company ELEMENTIS. 10 ~C 22 Examples of modified clays include modified magnesium silicate (Bentone gel VS38 manufactured by Rheox) and hectorite modified with .

[0109] The source of such clays can be natural or synthetic mineral clays such as hectorite, bentonite, and their quaternized derivatives, for example obtained by reacting minerals with quaternary ammonium compounds such as stearalkonium bentonite, hectorite, quaternized hectorites such as quaternium-18 hectorite, carbonates such as propylene carbonate, bentones, and the like.
