Best embodiment of the invention After careful research, the inventors discovered that it is possible to propose a composition with improved foaming properties in terms of ease of foaming and foam volume, and thus finalized the invention. The composition according to the present invention comprises a combination of (a) at least one modified starch, (b) at least one C,3-C;5 fatty acid, (c) at least one powdered organic salt and (d) water. The present invention will be described in detail below. [Composition] One aspect of the present invention is a composition comprising: a) at least one modified starch; (b) at least one C13-C15 fatty acid; (c) at least one powdered organic salt; and (d) water. Each of the ingredients will be described in more detail below. (Modified starch) The composition according to the present invention comprises (a) at least one modified starch. Only one type of modified starch may be used, or two or more different types of modified starches may be used in combination. (a) Modified starch can be in powder form. In other words, modified starch (a) can be in granular form. In this case, the particle size of (a) modified starch is not limited. It is preferable that (a) the modified starch be film-forming, that is, that it be capable of forming a film. (a) Modified starch is based on base starch. Base starch, as used in this document, is intended to include all starches derived from any native source, any of which may be suitable for use in this document. Native starch, as used in this document, is starch found in nature. Starches derived from a plant obtained by standard breeding techniques, including crossing, translocation, inversion, transformation, or any other genetic or chromosome engineering process, to include variations thereof, are also suitable. In addition, starches derived from a cultivated plant from artificial mutations and variations of the above generic starches that can be produced by known standard processes of mutation breeding are also suitable in this document. Typical sources of starch include cereals, tubers, roots, legumes, and fruits. Native sources can include waxy varieties of maize, peas, potatoes, sweet potatoes, bananas, barley, wheat, rice, oats, sago, amaranth, cassava, arrowroot, canna, and sorghum, as well as their low- and high-amylose varieties. As used in this document, the term "low-amylose starch" refers to starchy foods. The term "amylose content" is intended to include starch containing no more than about 10%, in particular no more than 5%, and more particularly no more than 2% by weight of amylose. As used in this document, the term "high amylose starch" is intended to include starch containing at least about 50%, in particular at least about 70%, and more particularly at least about 80% by weight of amylose. High amylose starches may be preferable. (a) Modified starch can be pregelatinized. Pregelatinization and techniques for achieving pregelatinization are known in the art and disclosed, for example, in US patents Nos. 4,465,702, 5,037,929, 5,131,953, and 5,149,799. See also Chapter XXII, "Production and Use of Pregelatinized Starch," in Starch: Chemistry and Technology, Vol. II—Industrial Aspects, R.L. Whistler and E.F. Paschall, Editors, Academic Press, New York, 1967. The term pregelatinized is understood to refer to swollen starch particles that have lost their birefringence and / or Maltese crosses in polarized light. These 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 can also mean a colloidal dispersion. In one embodiment, the starch is completely pregelatinized. Pregelatinized modified starch is easily and quickly soluble, even in cold water. Pre-gelatinization can be achieved by methods including, but not limited to, drum drying, extrusion, and spray drying. In one embodiment, extrusion is used for the simultaneous cooking and drying of starch (see, for example, US Patent No. 3,137,592). This process uses the physical treatment of a starch / water mixture at high temperatures and pressures, resulting in the gelatinization of the starch, followed by expansion after exiting the nozzle with rapid evaporation of the water. In one embodiment, pre-gelatinization is carried out to provide good solubility and eliminate undissolved particles, which can give rise to an unpleasant, gritty feel in the composition. In one embodiment, the starch has a majority of intact starch granules. Aqueous dispersions of pregelatinized starch derivatives with a largely intact granular structure generally have a smoother, more uniform texture than aqueous dispersions of starches without a granular structure, which can have a slightly abrasive feel. In the case of pregelatinized starches with an intact granular structure, the native internal structure of hydrogen bonds is destroyed, but the external shape is maintained. (a) Modified starch can be crosslinked. Crosslinking of the starch chains can be achieved by suitable crosslinking agents, i.e., bifunctional compounds. In one embodiment, the crosslinking process used is phosphorylation, in which the starch is reacted with phosphorus oxychloride, phosphorus pentoxide, and / or sodium trimetaphosphate. Two starch chains are crosslinked by an anionic PO₄ group. The anionic nature of the crosslinking sites contributes to the emulsion-stabilizing action of the starch used according to the present invention. In another embodiment, the crosslinking process is carried out using C,-Cy alkene or alkane dicarboxylic acids, which include, without limitation, C4-C alkane dicarboxylic acids, an example of which is adipic acid. The alkane or dicarboxylic alkene links two starch chains via ester bonds.It can be in the form of a straight or branched chain. Derivatives can be obtained, for example, by reacting starch with mixed anhydrides of dicarboxylic acid and acetic acid. In one embodiment, less than 0.1% by weight based on the dry starch crosslinking agent is used. In another embodiment, approximately 0.06 to 0.1% by weight based on the dry starch crosslinking agent is used. It is preferable that (a) the modified starch be hydrophobic. It is even more preferable that the surface of (a) the modified starch be hydrophobic. The modification to make starch hydrophobic can be achieved by grafting hydrophobic functional groups such as the C,5 acyl (acetyl), C,5 hydroxyalkyl (hydroxyethyl or hydroxypropyl), carboxymethyl or octenyl-succinic group. The alkyl fraction of the functional group can have | up to 6 carbon atoms, preferably 2 to 5 carbon atoms and, more preferably, 3 or 4 carbon atoms. It is preferable that (a) the modified starch be hydroxyalkyl modified starch. The position of the hydroxyl group, which is linked to the starch backbone via an alkyl group (such as 2 to 6 carbon atoms in the alkyl group), is not critical and can be in the alpha to omega positions. In a suitable 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 unit of anhydroglucose. The hydroxyalkylation of a starch can be induced by reacting native starch with alkylene oxides having the appropriate number of carbon atoms, including, but not limited to, hydroxypropylation by reacting starch with propylene oxide. The hydroxyalkyl-modified starch may also contain more than one hydroxyl group per alkyl group. Hydroxyalkyl modified starch can be selected from the group consisting of hydroxyethyl starch, hydroxypropyl starch, hydroxyethyl starch phosphate, hydroxypropyl starch phosphate and a mixture of these. The processes for preparing hydroxyalkyl-modified starch can be carried out in any order. However, those skilled in the art would understand the advantages of certain orders. For example, hydroxypropylation would generally be carried out before crosslinking, if the starch is crosslinked, with phosphorus oxychloride, because the typical hydroxypropylation process would destroy some of the crosslinking achieved. Examples of hydroxyalkyl-modified starch preferably used in the present invention may include the following: Hydroxypropyl starch phosphate (pregelatinized corn starch) marketed by Akzo Nobel under the names Structure ZEA and XL; and Modified corn starch (hydroxypropyl, pregelatinized, high amylose content) marketed by Nouryon under the name AMAZE. 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. Furthermore, the amount of (a) modified starch in the composition according to the present invention may be 15% by weight or less, preferably 10% by weight or less, more preferably 5% by weight or less, and even more preferably 3% by weight or less, relative to the total weight of the composition. The amount of (a) modified starch in the composition according to the present invention may range from 0.01% to 15% by weight, preferably from 0.1% to 10% by weight, more preferably from 0.5% to 5% by weight, and even more preferably from 1% to 3% by weight, relative to the total weight of the composition. In the context of this paper, any combination of the upper limit values ​​and lower limit values ​​above may be available to represent the preferred range of quantity. (C,3-C15 fatty acid) The composition according to the present invention comprises (b) at least one C,3-C;s fatty acid. A single type of C,,,-C;5 fatty acid, or two or more different types of C,3-C;s fatty acids may be used in combination. It is preferable that (b) the C13-Cy5 fatty acid be saturated. The saturated C13-Cys fatty acid can be chosen from the group consisting of tridecyl acid (tridecanoic acid), myristic acid (tetradecanoic acid) and pentadecyl acid (pentadecanoic acid). It is possible that (b) the C,3-C;s fatty acid is unsaturated. The unsaturated C 13-Cys fatty acid can be chosen from the group consisting of tridecenoic acid, myristoleic acid (tetradecenoic acid) and pentadecenoic acid. It is preferable that (b) the C13-C15 fatty acid be myristic acid. The amount of (b) the C;3-C1;5 fatty acid in the composition according to the present invention may be 1% by weight or more, preferably 2% by weight or more, and more preferably 3% by weight or more, and even more preferably 4% by weight or more, relative to the total weight of the composition. Furthermore, the quantity of (b) the C;3-C;5 fatty acid in the composition according to the present invention may be 20% by weight or less, preferably 15% by weight or less, more preferably 10% by weight or less, and even more preferably 8% by weight or less, relative to the total weight of the composition. The quantity of (b) the C,3-C15 fatty acid in the composition according to the present invention can range from 1% to 20% by weight, preferably from 2% to 15% by weight, more preferably from 3% to 10% by weight, and even more preferably from 4% to 8% by weight, relative to the total weight of the composition. The weight ratio of the amount (weight) of (b) the C13-C;s fatty acid / the amount (weight) of (a) the 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. (a) Modified starch and (b) C,2-C,s fatty acid can form a complex. (Organic salt powder) The composition according to the present invention comprises (c) at least one powdered organic salt. Only one type of powdered organic salt may be used, or two or more different types of powdered organic salts may be used in combination. The (c) organic salt in powder form can act to improve the foaming properties of the composition according to the present invention. While not bound by theory, it is thought that (c) powdered organic salt can disrupt the network of water-based compositions, thereby facilitating the fusion of the composition with water upon contact. It is believed that such a function of powdered organic salt can impart improved foaming properties to the composition, particularly enhanced foaming ability. The term "powder" used in this document should be understood as particles of any shape, which are insoluble in the medium of the composition, in particular water. (c) Organic salt in powder form may be of any shape, platelet, spherical or oblong, regardless of the crystallographic form (e.g. lamellar, cubic, hexagonal, orthorhombic, etc). The average particle size of (c) powdered organic salt is not limited. For example, the average particle size of (c) powdered organic salt may be 50 µm or less, preferably 20 µm or less, and more preferably 10 µm or less. The average particle size of (c) powdered organic salt may be 0.01 µm or more, and preferably 0.1 µm or more. The term "average particle size" used in this document represents a number-average size-average diameter given by the statistical particle size distribution to half the population, denoted by DS0. For example, the number-average size-average diameter may be measured by a laser diffraction particle size distribution analyzer, such as the Mastersizer 2000 from Malvern Corp. (c) Powdered organic salt may be insoluble in water. The expression "insoluble in water" here indicates substances that are soluble in water at a concentration of less than 0.1% by weight, in particular less than 0.01% by weight, relative to the total weight of water at room temperature (25°C) and atmospheric pressure (10°Pa). A cationic fraction of the powdered organic salt may be selected from among the metallic cations and the organic cations. Preferably, the cationic fraction of the powdered organic salt is selected from among the metallic cations. Thus, (c) powdered organic salt is preferably a powdered organometallic salt. The (c) organic salt in powder form may be selected from organometallic salts with a monovalent metal ion and organometallic salts with a divalent or higher metal ion. Organometallic salts with a monovalent metal ion may include sodium salts, potassium salts, cesium salts, and lithium salts. Organometallic salts with a divalent or higher metal ion may include calcium salts, magnesium salts, cobalt salts, nickel salts, copper salts, iron salts, manganese salts, strontium salts, molybdenum salts, barium salts, zinc salts, and aluminum salts. In a preferred embodiment of the present invention, the powdered organometallic salt can be chosen from organometallic salts with divalent or higher metal ion, and more preferably from calcium salts, magnesium salts and aluminum salts. (c) powdered organic salt may also be chosen from organic salts with monovalent organic ions, such as ammonium salts, sulfonium salts and phosphonium salts. Organic powdered salt can be chosen from fatty acid salts, modified polysaccharide salts, and a combination thereof. The fatty acid salt(s) may comprise a long hydrophobic hydrocarbon chain, which is linear or branched and saturated and unsaturated, for example, having 6 to 30 carbon atoms, in the form of a carboxylate anion (a fatty acyl); and a cation, as illustrated in the following formula: (RC(=0)-0-),M(+) in which R is a linear or branched substituted or unsubstituted hydrocarbon chain of 6 to 30 carbon atoms, M* is a cation, and n is an integer representing the number of fatty acyls that interact with the cation, and also represents the charge number of the cation (e.g., 1, 2, 3, etc.). The fatty acid salts that can be used in some of the embodiments of the present invention may contain 1 to 3 fatty acyl chains, and preferably two chains. Thus, the fatty acid salt may be a salt of a monovalent ion, a divalent ion, or a trivalent ion, and preferably of a divalent ion. Each fatty acyl chain, independently, can be linear or branched, saturated and unsaturated, preferably linear and saturated, and / or can comprise 6 to 30 carbon atoms, preferably 8 to 24 carbon atoms, and more preferably 12 to 22 carbon atoms in length. The cations can be metal ions, such as a monovalent metal ion, a divalent metal ion, and a trivalent metal ion. The monovalent metal ion can be chosen from Na*, K*, Cs*, and Li*. The divalent metal ion can be chosen from Mg*, Ca®, Fe(II), Co²⁺, Ni²⁺, Cu²⁺, Mn²⁺, S²⁺, Mo²⁺, and Zn²⁺. The trivalent metal ion can be chosen from Fe(II) and Al**. Preferably, the metal ion is chosen from among the divalent metal ions, and more preferably from Mg²⁺ and Ca²⁺. The cations can be organic cations, which can be chosen from an ammonium cation, a sulfonium cation and a phosphonium cation. In a preferred embodiment, the fatty acid salt comprises metallic ions, which are called "metallic fatty acid salts". The fatty acid in fatty acid salts may be selected from linear or branched, saturated and unsaturated fatty acids, and preferably linear and saturated fatty acids, which may have lengths of 6 to 30 carbon atoms, preferably 8 to 24 carbon atoms, and more preferably 12 to 22 carbon atoms. Examples of fatty acids include stearic acid, arachidic acid, palmitoleic acid, oleic acid, linoleic acid, linolaidic acid, arachidonic acid, myristoleic acid, and erucic acid. Other fatty acids are also considered. In some preferred embodiments, the fatty acid salt is selected from metallic fatty acid salts.

In a preferred embodiment, the metallic salt of fatty acid is selected from calcium stearate, magnesium stearate, and a combination thereof. The modified polysaccharide salt may be a water-insoluble modified polysaccharide salt. In one embodiment, the polysaccharide has been modified to be water-soluble. Thus, it is preferable for the modified polysaccharide to be hydrophobic. It is even more preferable for the surface of the modified polysaccharide to be hydrophobic. Preferably, the polysaccharide in the modified polysaccharide salt is starch. Thus, the modified polysaccharide salt is preferentially chosen from among the modified starch salts. Modified starch is based on base starch. Starch is understood to include all starches derived from any native source, any of which may be suitable for use in this document. Native starch, as used in this document, is starch found in nature. Starches derived from a plant obtained by standard breeding techniques, including crossing, translocation, inversion, transformation, or any other genetic or chromosome engineering process, to include variations thereof, are also suitable. In addition, starches derived from a cultivated plant from artificial mutations and variations of the above generic starches, which can be produced by known standard mutation breeding processes, are also suitable in this document. Typical sources of starch include grains, tubers, roots, legumes, and fruits. Native sources can include waxy varieties of maize, peas, potatoes, sweet potatoes, bananas, barley, wheat, rice, oats, sago, amaranth, cassava, arrowroot, canna, and sorghum, as well as their low- and high-amylose varieties. Starches with a high amylose content may be preferable. Modified starch can be pregelatinized. In one embodiment, the starch is completely pregelatinized. Pregelatinized modified starch is easily and rapidly soluble, even in cold water. In one embodiment, the pre- Gelatinization is carried out to provide good solubility and eliminate undissolved particles, which can give rise to an unpleasant and gritty feeling in the composition. In one embodiment, the starch has a majority of intact starch granules. Aqueous dispersions of pregelatinized starch derivatives with a largely intact granular structure generally have a smoother, more uniform texture than aqueous dispersions of starches without a granular structure, which can have a slightly abrasive feel.

Two starch chains are crosslinked by an anionic PO₄ group. The anionic nature of the crosslinking sites contributes to the emulsion-stabilizing action of the starch used according to the present invention. In another embodiment, the crosslinking process is carried out using C₅-Cy₃ alkene or alkane dicarboxylic acids, which include, without limitation, C₄-Cy₅ alkane dicarboxylic acids, an example of which is adipic acid. The alkane or dicarboxylic alkene links two starch chains via ester bonds.It can be in the form of a straight or branched chain. Derivatives can be obtained, for example, by reacting starch with mixed anhydrides of dicarboxylic acid and acetic acid. In one embodiment, less than 0.1% by weight based on the dry starch crosslinking agent is used. In another embodiment, approximately 0.06 to 0.1% by weight based on the dry starch crosslinking agent is used. It is preferable for the modified starch to be hydrophobic. It is even more preferable for the surface of the modified starch to be hydrophobic. The modification to make starch hydrophobic can be achieved by grafting hydrophobic functional groups such as the C,5 acyl group (acetyl), C,5 hydroxyalkyl (hydroxyethyl or hydroxypropyl), phosphate, alkyl phosphate, hydroxyalkyl phosphate, carboxymethyl or octenylsuccinic. In some preferred embodiments of the present invention, the modification is an esterification.

The modified polysaccharide salt may be water-insoluble metallic salts of modified polysaccharides or water-insoluble organic salts of modified polysaccharides. In one embodiment, the modified polysaccharide salt is water-insoluble metallic salts of modified polysaccharides. Preferably, the water-insoluble metallic salts of modified polysaccharides are modified starch metallic salts. In some other preferred embodiments, the modified starch metal salt is selected from starch octenylsuccinate metal salts, such as aluminum starch octenylsuccinate and sodium starch octenylsuccinate, and more preferably aluminum starch octenylsuccinate. The quantity of (c) organometallic salt in powder form in the composition according to the present invention may be 0.1% by weight or more, preferably 0.3% by weight or more and, more preferably, 0.5% by weight or more, relative to the total weight of the composition.

Furthermore, the quantity (d) of water may be 70% by weight or less, preferably 65% ​​by weight or less, and more preferably 60% by weight or less, relative to the total weight of the composition. The quantity (d) of water may be from 20% to 70% by weight, preferably from 30% to 65% by weight and, more preferably, from 35% to 60% by weight, relative to the total weight of the composition. (Other ingredients) - Clay The composition according to the present invention may comprise at least one clay. One Only one type of clay can be used, but two or more different types of clay can be used in combination. The term "clay" refers to a natural material composed primarily of fine-grained minerals, which is generally plastic at an appropriate water content and hardens when dried or fired. Although clay usually contains phyllosilicates, it may contain other materials that impart plasticity and harden upon drying or firing. Associated phases in clay may include materials that do not confer plasticity and organic matter. A common definition is that of the Penguin Dictionary of Science: "finely divided rock materials whose mineral components are various silicates, primarily magnesium or aluminum." Clay includes kaolinite (typically defined as [Si,)AlO,O(OH)s.nH;O (n=0 or 4)), illite (typically defined as M,[SisAl, 2]AlFe O2:ME 750» (OH).), vermiculite (typically defined as .M,[Si;A]]AlFe.osMgosO» (OH),), smectite (typically defined as M,[Sig]Als2Feo.:MgosO2 (OH), chlorite (typically defined as (Al(OH)55)a [SissAlO, 2} Als4Mgo6)»O(OH);), and phylosilicate minerals or talc (typically defined as Mg:Si,O,O(OH)). . Another definition, frequently used by chemists, is "a sediment or sedimentary rock of natural origin composed of one or more minerals and accessory compounds, the whole usually being rich in hydrated aluminum silicate, iron or magnesium, hydrated alumina, or iron oxide, having particles predominantly of colloidal or near-colloidal size, and commonly developing plasticity when sufficiently pulverized and wetted" (see Kirk-Othmer, Encyclopaedia of Chemical Technology, Volume 5, page 544, 2nd edition, John Wiley and Sons, Inc., New York, 1964). Examples of clays are given in the book "Clay Mineralogy," S. Caillere, S. Hénin, M. Rautureau, 2nd edition 1982, Masson. Clays can be of natural or synthetic origin. Hydrophilic clay includes smectites such as saponites, hectorites, montmorillonites, bentonites, and beidellite. Hydrophilic clay includes synthetic hectorites (also called laponites) such as the products sold by the company under the name Laporte Laponite XLG, Laponite RD, Laponite RDS (these products are sodium silicates and magnesium silicates, in particular sodium, lithium, and magnesium silicates), bentonites such as the product sold under the name Bentone® HC Rheox, magnesium silicates, and aluminum-based products such as the hydrated products sold by the Vanderbilt company under the names Ultra Veegum®, Veegum® HS, Veegum® DGT, or calcium silicates, and in particular the synthetic form sold by the company under the name Micro-cel® C. Fuller's earth is primarily composed of hydrated aluminum silicates which They contain metallic ions such as magnesium, sodium, and calcium within their structure. Montmorillonite is the main clay mineral in fuller's earth, but it can contain other minerals such as kaolinite, attapulgite, and palygorskite, among other components. A lipophilic clay is a clay that swells in a lipophilic medium; the clay swells and forms a colloidal dispersion. Lipophilic clays include modified clays such as modified magnesium silicate (Rheox's Bentone VS38 gel), and hectorites modified with ammonium chloride of C,p to C2 fatty acids, such as ammonium chloride-modified hectorite, distearyldimethylammonium (CTFA name: Disteardimonium hectorite) sold as "Bentone 38 CE" by Rheox or Bentone® 38V by ELEMENTIS. The origin of such clay may be a natural or synthetic mineral clay, such as hectorite, bentonite and their quaternized derivatives, for example obtained by reacting the minerals with a quaternary ammonium compound, such as stearalkonium bentonite, hectorites, quaternized hectorites such as Quaternium-18 hectorite, carbonates such as propylene carbonate, bentones, and the like.
