Personal care and household care compositions comprising a conditioner and rheology modifier based on a cationic galactomannan or cationic xyloglucan having cationic degree of substitution comprised between 0.01 and 3, free from (3-chloro-2-hydroxypropyl)trimethyl ammonium chloride and free from (2,3-epoxypropyl) trimethyl ammonium chloride.

Cosmetic and household care compositions

Method for inhibiting the swelling and the dispersion of shales in the treatment of subterranean shale formations comprising the use of a cationic tamarind gum and fluids for the treatment of subterranean shale formations comprising a cationic tamarind gum.

Shale inhibitors based on cationic tamarind gum, and drilling fluid comprising the shale inhibitor

Personal care and household care compositions comprising a conditioner and rheology modifier based on a cationic galactomannan or cationic xyloglucan having cationic degree of substitution comprised between 0.01 and 3, free from (3-chloro-2-hydroxypropyl)trimethyl ammonium chloride and free from (2,3-epoxypropyl)trimethyl ammonium chloride.

Cosmetic and household care composition

The present invention relates to ready-to-use drying joint compounds that exhibit improved performance characteristics due to the presence of a hydrophobically modified polygalactomannan.

Joint compounds

An aqueous adjuvant concentrate can be prepared using a formulation including: a. from about 15 to about 45% by weight of a potassium salt chosen among di-potassium phosphate, potassium sulfate, potassium nitrate, tri-potassium citrate, potassium salts of ethylenediaminetetraacetic acid and mixture thereof; b. from about 0.5 to about 6% by weight of at least one surfactant and c. from about 3 to about 9% by weight of a hydroxypropyl tamarind gum; wherein a, b, and c are dissolved into the aqueous adjuvant. The aqueous adjuvant can include other compounds such as ah herbicide.

Aqueous adjuvant concentrates with improved spray drift properties

The present disclosure relates to a method of treating a portion of a subterranean formation comprising the use of an aqueous fracturing fluid containing a fast dissolving and easily dispersible unpunfied polygalactomannan ether.

Method of treating subterranean formations

Aqueous adjuvant concentrate with improved spray drift properties and method for its preparation comprising the steps of: i) dissolving from 15 to 30% by weight, on the weight of the final concentrate, of ammonium sulfate in water; ii) adding to the solution from 1 to 10% by weight, on the weight of the final concentrate, of anionic esters of alkyl polyglycosides; iii) dispersing in the solution from 2 to 10% by weight, on the weight of the final concentrate, of hydroxypropyl guar or hydroxypropyl guar acetate; iiii) adding ammonium sulfate to the dispersion to reach an ammonium sulfate final concentration comprised between 33 and 40% by weight.

Compositions comprising a hydraulic binder such as cement or gypsum and a hydroxypropyl guar derivative that comprises unsubstituted linear or branched C-Calkyl chains possess excellent water retention characteristics.

Hydraulic binder composition

A glyoxal and boron free purified cationic polygalactomannan may be prepared by reacting a polygalactomannan flour, a nonionically derivatized polygalactomannan flour, or a mixture thereof, with a cationising reagent, adjusting the pH to be from about 4 to about 6; cross-linking the cationic with glyoxal, and filtering and water washing the cationic polygalactomannan to produce a glyoxalated purified cationic polygalactomannan containing not more than 70% by weight of water. In some cases it may be desirable to introduce a buffering agent to the glyoxalated purified cationic polygalactomannan to regulate the pH to from 8.0 to about 9.5, when measured at 1% (dry matter) in water. In other cases, it may be desirable to remove water to produce glyoxal free purified cationic polygalactomannan in powder form. Such compounds are particularly useful in personal care products.

Glyoxal free purified cationic polygalactomannan

Cationic hydrophobically modified galactomannan ethers having a cationic degree of substitution (DS) from 0.01 to 0.5 and hydrophobic degree of substitution (DS) below 0.001 are readily soluble in aqueous systems and useful to thicken, stabilize and condition cosmetics, detergent compositions and household cleaning products; they further improve the deposition of other ingredients on the treated surface (skin, hair or fabric).
