This invention relates to a cationically and hydrophobically modified polygalactomannan with repeating units with a D-mannosyl to D-galactosyl residue ratio of at least 5 to 1 and to compositions containing same. A portion of the hydrogen atoms of hydroxyl groups situated on the mannosyl and galactosyl residues of the galactomannan are replaced with a hydrophobic substituent and a cationic substituent.

This invention generally relates to galactomannan derivatives. More specifically, the invention relates to cationically and hydrophobically modified galactomannan polymers obtained from the endosperm of seeds obtained from the plant genus Cassia and to their use in personal care, health care, household, institutional and industrial care compositions and the like. The cationically and hydrophobically modified Cassia galactomannan polymers of this invention are useful as deposition aids, stabilizers, emulsifiers, spreading aids and carriers for enhancing the efficacy, deposition and delivery of chemically and physiologically active ingredients. In addition, such polymers are useful as an active component in personal care compositions as film formers, hair fixatives, hair conditioners, deposition aids, and skin conditioners. These polymers are also useful for improving the psychosensory and aesthetic properties of personal care formulations in which they are included.
