Description

[0001] The present invention relates to the field of aqueous thickening compositions, in particular compositions capable of increasing the viscosity of aqueous paint or varnish compositions, detergent compositions or cosmetic compositions, in particular cosmetic compositions comprising ethoxylated surfactant compounds. The compositions according to the invention comprise at least 40% by weight of water and combine specific thickening compounds and non-ionic compounds comprising at least one hydrophilic saccharide group, said hydrophilic saccharide group being bound to at least one linear or branched hydrophobic chain.

[0002] A variety of thickeners are known to increase the viscosity of aqueous compositions, in particular polyurethane thickeners. However, these thickeners generally have a high viscosity in aqueous solution. Certain thickeners in the prior art are waxy at room temperature. The high viscosity in aqueous solution makes them difficult to transport or handle, especially when they are dispersed in the composition to be thickened. In particular, these thickeners must have a viscosity that enables them to be pumped. When preparing these thickeners, too high a viscosity can also cause problems.

[0003] To control this viscosity, thickeners in the prior art are generally diluted, in particular with water or organic solvents. Also to control their viscosity, thickeners in the prior art can be combined with plasticizer compounds, such as cyclodextrins, cyclodextrin derivatives or surfactant compounds, in particular ethoxylated surfactant compounds, anionic surfactant compounds or ethoxylated anionic surfactant compounds, and mixtures thereof.

[0004] These various means of controlling the viscosity of thickeners in the prior art have many disadvantages.

[0005] Dilution with water reduces the relative amount of thickener. Thus reducing the effect of viscosity control. Diluting the thickener with an organic solvent causes the same problem, as well as environmental problems and the diffusion of volatile organic compounds.

[0006] Controlling the viscosity of thickeners with plasticizer compounds in the prior art also causes problems. These problems can occur when using these thickeners or preparing them.

[0007] For example, the use of cyclodextrins, cyclodextrin derivatives or surfactant compounds introduces ionic charges into the thickener. The presence of these ionic charges makes the thickener sensitive to changes in pH during use. Then this sensitivity unpredictably disrupts the thickening effect.

[0008] Combining these plasticizer compounds with thickeners in the prior art results in a relative reduction in the amount of thickener, which disrupts viscosity control. Due to the potential adsorption of surfactants, the combined addition of water causes the same problem. Some surfactant plasticizer compounds can also disrupt or inhibit the thickening effect of thickeners in the prior art.

[0009] If several methods for controlling the viscosity of thickeners in the prior art are combined, other problems may arise, especially because of their chemical, physical or functional incompatibilities with each other. Combining different thickeners may also result in antagonistic effects.

[0010] Document CA 2816039 relates to a method for preparing polyurethanes that requires the presence of metal carboxylates. Document US6479573 relates to a method for thickening aqueous systems using water-soluble polyurethanes or hydrophobically terminated poly(acetal-ether).

[0011] Therefore, improved thickeners are necessary. These thickeners must be able to control the viscosities of the different components of the aqueous compositions in which they are used. For example, for coating compositions, the thickeners must be able to control the Brookfield viscosity, ICI viscosity, and Stormer viscosity at different shear gradients.

[0012] Preferably, the thickeners should also be partially or completely of natural origin. The stability of the thickeners must also be improved, especially: their stability during preparation, transportation, or storage.

[0013] The thickeners must also maintain their properties despite pH changes.

[0014] The compositions according to the invention can solve all or part of the problems of thickeners in the prior art.
