[0217] These guar gums are well-known in the prior art and can be prepared, for example, by reacting a corresponding alkene oxide, such as propylene oxide, with guar gum to obtain a guar gum modified with hydroxypropyl groups.

[0218] 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 in the guar gum.

[0219] Such nonionic guar gums optionally modified with hydroxyalkyl groups are sold, for example, under the trade names Jaguar HP8, Jaguar HP60, and Jaguar HP120 by Rhodia Chimie.

The anionic groups and cationic groups may be bonded to the same reaction site or different reaction sites of the starch molecule; preferably, they are bonded to the same reaction site. The anionic group can be of the carboxyl, phosphate or sulfate type, preferably of the carboxyl type. The cationic group can be of the primary, secondary, tertiary or quaternary amine type.

[0224] The starch molecule can particularly be derived from any plant starch source such as corn, potato, wheat, rice, tapioca, sorghum, barley or rye. It is also possible to use the hydrolyzates of the starches mentioned above. The starch is preferably derived from potato.

[0225] The non-associative thickening polymer of the present invention can be a cellulose-based polymer that does not contain a C 10 ~C 30 fatty chain.

[0228] Among these cellulosic polymers, cellulose ethers, cellulose esters, and cellulose ester ethers are well known.

[0229] Among cellulose esters, there are inorganic cellulose esters (such as cellulose nitrate, sulfate, phosphate, etc.), organic cellulose esters (such as cellulose monoacetate, triacetate, amidopropionate, acetate butyrate, acetate propionate, and acetate trimellitate, etc.), and organic / inorganic mixed esters of cellulose, such as cellulose acetate butyrate sulfate and cellulose acetate propionate sulfate. Among cellulose ester ethers, hydroxypropyl methylcellulose phthalate and ethylcellulose sulfate can be mentioned.

Examples include carboxymethyl cellulose, carboxymethyl methyl cellulose (e.g., Blanose 7M manufactured by Aqualon) and carboxymethyl hydroxyethyl cellulose, as well as their sodium salts.

[0306] (c) It is preferred that the colorant is selected from hydrophobic pigments.

[0307] Preferably, the hydrophobic pigment is selected from hydrophobic coated pigments. The term "hydrophobic coated pigment" means any pigment coated with at least one lipophilic or hydrophobic compound. The term "lipophilic compound" means any compound that is soluble or dispersible in oil. The term "hydrophobic compound" means any compound that is insoluble in water.

[0308] According to certain embodiments of the present invention, the pigments coated with at least one lipophilic or hydrophobic compound are selected from inorganic and organic pigments.

[0309] The hydrophobic pigment may have at least one coating comprising at least one lipophilic or hydrophobic compound. This lipophilic or hydrophobic coating may be present on the outermost surface of the hydrophobic pigment.

[0310] For the purposes of the present invention, "coating" of a pigment generally refers to the overall or partial surface treatment of the pigment with a surface treatment agent that is absorbed, adsorbed or grafted onto the pigment. Thus, the hydrophobic pigment may be a surface-treated pigment.

[0311] Surface-treated pigments can be prepared by surface treatment techniques of chemical, electronic, mechanochemical or mechanical nature, which are well known to those skilled in the art. Commercially available products can also be used as surface-treated pigments.

[0312] The surface treatment agent can be absorbed, adsorbed or grafted onto the pigment by evaporation of the solvent, chemical reaction and creation of covalent bonds.

[0313] According to one variant, the surface treatment consists of a coating of the pigment.

[0314] The hydrophobic pigment may also have at least one coating comprising at least one non-lipophilic or non-hydrophobic compound, for example at least one hydrophilic compound. For example, the non-lipophilic or non-hydrophobic compound can be selected from metal hydroxides, such as aluminum hydroxide, and metal chlorides, such as magnesium chloride. This non-lipophilic or non-hydrophobic coating may be present between the pigment itself and the lipophilic or hydrophobic coating.

[0315] The coating may occupy from 0.1% to 20% by weight, specifically from 0.5% to 5% by weight, based on the total weight of the coated pigment.

[0316] The coating can be carried out, for example, by simply mixing the particles with the surface treatment agent while stirring, optionally with heating, before incorporating the particles into the other components of the composition used for the purposes of the present invention, so as to adsorb the liquid surface treatment agent onto the surface of the solid pigment particles.

[0317] The coating can be carried out, for example, by chemically reacting the surface treatment agent with the surface of the solid pigment particles to create a covalent bond between the surface treatment agent and the particles. This method is described in particular in US-B-4,578,266.

[0318] The chemical surface treatment may consist of diluting the surface treatment agent in a volatile solvent, dispersing the pigment in this mixture, and then slowly evaporating the volatile solvent so that the surface treatment agent is deposited on the surface of the pigment.

[0319] According to a particular embodiment of the present invention, the pigment can be coated with at least one lipophilic or hydrophobic compound selected from silicone-based surface treatment agents, fluoro surface treatment agents, fluorosilicone surface treatment agents, metal soaps, fatty acids, N-acyl amino acids or their salts, lecithin and its derivatives, monoalkyl triacyl titanates such as isopropyl triisostearyl titanate, isostearyl sebacate, natural plant or animal waxes, polar synthetic waxes, fatty esters, phospholipids, and mixtures thereof.

Monoalkyl triacyl titanates, also referred to as monoalkyl titanates, can be represented by the formula RO-Ti-(OR')3, where R is an alkyl and R' is an acyl group, which may be the same or different.

[0321] In certain embodiments of the monoalkyl triacyl titanate, the alkyl is C 1~5 an alkyl group, specifically C 1~4 an alkyl group, and the acyl is derived from acrylic acid or an acrylic acid derivative, such as methacrylic acid, or a fatty acid. The acyl group is particularly C 6~30 a fatty acid, more specifically C 12~24 a fatty acid, even more specifically C 16~20 derived from a fatty acid. Such fatty acids may be capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, hydroxystearic acid, oleic acid. The acyl groups in these triacyl titanates may be the same or different. A preferred embodiment is monoisopropyl triacyl titanate, see U.S. Patent Application Publication No. 20050019284 (specifically paragraphs
