Dispersible non-borate metal salt or chelate treated polygalactomannan polymers for use in personal care and household care applications
The present invention relates to polygalactomannan compositions, and more particularly guar gum compositions, which, when crosslinked with organic chelating agents, such as non-borate metal salt or chelates, to 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 derivatives are desirable for use in applications such as personal care and household care products.

a non-borate metal salt or chelate treated polygalctomannan, and an active ingredient agent, wherein the composition is a personal care or household care product.
2 . The composition of claim 1 , wherein the non-borate metal salt or chelate treated polygalactomannan comprises a non-borate metal salt or chelate treated cationic polygalctomannan.
3 . The composition of claim 1 , wherein the non-borate metal salt or chelate treated cationic polygalctomannan is a non-borate metal salt or chelate treated cationic guar.
4 . The composition of claim 3 , wherein non-borate metal salt or chelate treated cationic guar has a substituent degree of substitution (DS) lower limit of about 0.001 and an upper limit of about 3.0.
5 . The composition of claim 3 , wherein non-borate metal salt or chelate treated cationic guar has a weight average molecular weight (Mw) with a lower limit of about 50,000 and an upper limit of about 5,000,000.
