[0144] Chemical treatments that may be mentioned include esterification, etherification, amidation and oxidation reactions. These treatments can lead to polymers that may especially be nonionic, anionic or amphoteric.
[0145] Preferably, the polysaccharide are not chemically or physically treated.
[0146] The nonionic guar gums that may be used according to the invention may be modified with Ci-C6(poly)hydroxyalkyl groups.
[0147] Among the Ci-Ce (poly)hydroxyalkyl groups, mention may be made, for example, of hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.
[0148] These guar gums are well known in the prior art and may be prepared, for example, by reacting the corresponding alkene oxides, for instance, propylene oxides, with the guar gum so as to obtain a guar gum modified with hydroxypropyl groups.
[0149] The degree of hydroxyalkylation preferably varies from 0.4 to 1.2 and corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functional groups present on the guar gum.
[0150] Such nonionic guar gums optionally modified with hydroxyalkyl groups are sold, for example, under the trade names Jaguar HP8, Jaguar HP60 and Jaguar HP 120 by the company Rhodia Chimie.
[0151] Among the starches that may be used, mention may be made, for example, of macromolecules in the form of polymers comprising base units which are anhydroglucose units. The number of these units and their assembly make it possible to distinguish between amylose (linear polymer) and amylopectin (branched polymer). The relative proportions of amylose and amylopectin, as well as their degree of polymerization, can vary according to the botanical origin of the starches.
[0152] The botanical origin of the starch molecules that may be used in the present invention may be cereals or tubers. Thus, the starches are chosen, for example, from com starch, rice starch, cassava starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch.
[0153] The starches may be chemically or physically modified, in particular by one or more of the following reactions: pregelatinization, oxidation, crosslinking, esterification, etherification, amidation, heat treatments.
[0154] Distarch phosphates or compounds rich in distarch phosphate will preferentially be used, for instance the product sold under the references Prejel VA-70-T AGGL (gelatinized hydroxypropyl cassava distarch phosphate), Prejel TK1 (gelatinized cassava distarch phosphate) and Prejel 200 (gelatinized acetyl cassava distarch phosphate) by the company Avebe, or Structure Zea from National Starch (gelatinized com distarch phosphate).
[0155] According to the invention, amphoteric starches may also be used, these amphoteric starches comprising one or more anionic groups and one or more cationic groups. The anionic and cationic groups may be bonded to the same reactive site of the starch molecule or to different reactive sites; they are preferably bonded to the same reactive site. The anionic groups may be of carboxylic, phosphate or sulfate type, preferably carboxylic. The cationic groups may be of primary, secondary, tertiary or quaternary amine type.
[0156] The starch molecules may be derived from any plant source of starch, in particular those such as com, potato, oat, rice, tapioca, sorghum, barley or wheat. It is also possible to use the hydrolyzates of the starches mentioned above. The starch is preferably derived from potatos.
[0157] The starches may be optionally Ci-Ce hydroxyalkylated or Ci-Ce acylated (such as acetylated). The starches may have also undergone heat treatments.
[0158] The polysaccharide may be cellulose-based polymers not comprising a C10-C30 fatty chain in their structure.
[0159] According to the invention, the term "cellulose-based, polymer" means any polysaccharide compound having in its structure sequences of glucose residues linked together via D-1,4 bonds; in addition to unsubstituted celluloses, the cellulose derivatives may be anionic, cationic, amphoteric or nonionic.
[0160] Thus, the cellulose polymers that may be used according to the invention may be chosen from unsubstituted celluloses, including those in a microcrystalline form, and cellulose ethers.
[0161] Among these cellulose-based polymers, cellulose ethers, cellulose esters and cellulose ester ethers are distinguished.
[0162] Among the cellulose esters are mineral esters of cellulose (cellulose nitrates, sulfates, phosphates, etc.), organic cellulose esters (cellulose monoacetates, triacetates, amidopropionates, acetatebutyrates, acetatepropionates and acetatetrimellitates, etc.), and mixed organic / mineral esters of cellulose, such as cellulose acetatebutyrate sulfates and cellulose acetatepropionate sulfates. Among the cellulose ester ethers, mention may be made of hydroxypropylmethylcellulose phthalates and ethylcellulose sulfates.
[0163] Among the nonionic cellulose ethers without a C10-C30 fatty chain, i.e. which are "non- associative", mention may be made of (Ci-C4)alkylcelluloses, such as methylcelluloses and ethylcelluloses (for example, Ethocel standard 100 Premium from Dow Chemical);
[0164] (poly)hydroxy(Ci-C4)alkylcelluloses, such as hydroxymethylcelluloses, hydroxyethylcelluloses (for example, Natrosol 250 HHR provided by Aquaion) and hydroxypropylcelluloses (for example, Klucel EF from Aquaion); mixed (poly)hydroxy(Ci- C4)alkyl-(Ci-C4)alkylcelluloses, such as hydroxypropylmethylcelluloses (for example, Methocel E4M from Dow Chemical), hydroxyethylmethylcelluloses, hydroxyethylethylcelluloses (for example, Bermocoll E 481 FQ from Akzo Nobel) and hydroxybutylmethylcelluloses.
[0165] Among the anionic cellulose ethers without a fatty chain, mention may be made of (poly)carboxy(Ci-C4)alkylcelluloses and salts thereof. By way of example, mention may be made of carboxymethylcelluloses, carboxymethylmethylcelluloses (for example Blanose 7M from the company Aquaion) and carboxymethylhydroxyethylcelluloses, and the sodium salts thereof.
[0166] Among the cationic cellulose ethers without a fatty chain, mention may be made of cationic cellulose derivatives such as cellulose copolymers or cellulose derivatives grafted with a water-soluble quaternary ammonium monomer, and described in particular in patent US 4,131,576, such as (poly)hydroxy(Ci-C4)alkyl celluloses, for instance hydroxymethyl-, hydroxyethyl- or hydroxypropylcelluloses grafted in particular with a methacryloylethyltrimethylammonium, methacrylamidopropyltrimethylammonium or dimethyldiallylammonium salt. The commercial products corresponding to this definition are more particularly the products sold under the names Celquat L 200® and Celquat H 100® by the company National Starch.

[0289] The nomenclature of the silicone resin is known in the art under the name of “MDTQ” nomenclature, by which a silicone resin is described according to the various repeating siloxane monomer moieties which constitute the polymer. Each letter of “MDTQ” corresponds to a different type of moiety.
[0290] The symbol “M” corresponds to the monofunctional moiety R -SiOi / i. This moiety is regarded as monofunctional because the silicon atom shares only one oxygen for the formation of the chain. The R1group indicates a hydrocarbon group, preferably an alkyl group or aryl group, and more preferably a C1-C10 alkyl group, in particular a C1-C4 alkyl group, such as a methyl group, an ethyl group, a propyl group, or a butyl group. The “M” moiety can be represented by the following structure:

[0301] In one preferred embodiment, the siloxysilicate is trimethylsiloxysilicate, which is represented by [(CH3)3SiO]x(SiO4 / 2)y in which x and y represent from 10 to 150, preferably from 20 to 120, more preferably from 40 to 100, and in particular from 50 to 80, for example, sold by the company Momentive Performance Materials under the name SR 1000 MQ Resin.
