Definitions

• the present invention relates to polygalactomannan compositions and more particularly guar gum compositions which, when crosslinked with titanate organic chelating agents, form discrete guar particles which are capable of being easily dispersed in water which permits subsequent processing of the guar such as washing.
• the guar and its derivative are desirable for use in applications such as personal care or household care products, and the like.
• Polygalactomannans and their derivatives are used in various applications such as oil recovery, personal care products, textile applications, paper applications, coating applications, food applications, etc. Polygalactomannans and their derivatives are difficult to disperse in aqueous solutions, as they tend to form sticky particles which clump and agglomerate, making dissolution difficult.
• crosslinking agents such as borax, are used to allow for water-washing of the polygalactomannan after reaction and for improved dispersibility of the polygalactomannan in water.
• crosslinking agents based on borate salts, aluminum salts, copper, iron, lead, calcium, and sodium salts have been described.
• Other crosslinking agents such as metal salts based on titanium and zirconium have been mentioned, without clear definition of the method or procedure for their use.
• a boron free coating onto the substrate, that reduces the energy needed to move a comb through hair in the wet or dry state or delivers a silky, soft feel to skin or to fabric.
• This coating can also act to improve the luster and moisture retention of hair and skin, as well as their manageability and feel.
• the present invention relates to a process for producing a polygalactomannan.
• the polygalactomannan is produced in a process comprising the steps of obtaining a polygalactomannan and then contacting the polygalactomannan with an effective amount of a non-borate metal salt or chelate to produce a crosslinked polygalactomannan particle.
• the preferred non-borate metal salt or chelate comprises a metal salt based on titanium or zirconium.
• the crosslinked polygalactomannan particle is then dispersed in water having a pH in the range of from below about 12 to about 7 and washed in the water to remove impurities from the crosslinked polygalactomannan particle.
• the present invention is directed to a personal care or household care composition
• a personal care or household care composition comprising a non-borate metal salt or chelate crosslinked polygalactomannan polymer and derivatives, especially titanium and zirconium crosslinked polygalactomannan containing cationic substituents.

• the low impurity content polygalactomannan is of particular utility in applications where the use of boron containing compounds is to be reduced or eliminated.
• Polygalactomannans are polysaccharides composed principally of galactose and mannose units and are usually found in the endosperm of leguminous seeds such as guar, locust bean, honey locust, flame tree, and the like.

• the most commonly used polygalactomannan is guar.
• the guar may be underivatized guar as well as derivatized guars such as cationic guar, anionic guar, hydrophobic guar, and hydroxyalkyl guar.
• An advantage of the use of titanate chelates over borate salts is that borate salts disassociate in water at a higher pH than titanate chelates. This results in the formation of swelled gel particles or a gel mass at a higher pH.
• washing of the polygalactomannan over a greater pH range may be performed and thereby permitting removal of impurities that would not be removed at the higher pH ranges, such as alkaline species. These impurities may reduce the clarity of aqueous solutions of the polygalactomannan or be harmful if permitted to remain with the galactomannan in certain end use applications, such as personal care.
