Cationic cassia derivatives and applications therefor

A method for using a cationically functionalized cassia galactomannan as a deposition aid for chemically, cosmetically, or physiologically active ingredients contained in a personal care or healthcare composition, said method comprising applying said personal care or healthcare composition to hair, skin, nails, scalp, mouth, mucous membranes, teeth and eyes, wherein a portion of the hydrogen groups in the pendant hydroxy groups of the cationically functionalized cassia galactomannan are substituted with a group represented by the formula:

• -AR1
• wherein A is a substituted or unsubstituted alkylene group containing 1 to 6 carbon atoms, and R1is a group independently selected from —N(R3)3+X−, —S(R3)2+X−, and —P(R3)3+X−, wherein R3 independently represents substituted and unsubstituted C1to C24 alkyl, substituted and unsubstituted benzyl and substituted and unsubstituted phenyl;
• and X is any suitable anion that balances the charge on the onium cation.
