THE PRESENT INVENTION PRESENTS A CATIONIC POLYMER. WHEN A HAIR TREATMENT COMPOSITION CONTAINING THE CATIONIC POLYMER IS USED TO DAMAGED HAIR, EXCELLENT CONDITIONING EFFECTS ARE SHOWN. WHEN A SKIN COSMETIC TREATMENT COMPOSITION CONTAINING THE CATIONIC POLYMER, FOAM FORMATION AND FOAM QUALITY ARE IMPROVED AND GOOD USE FEELING IS OBTAINED. THE PRESENT INVENTIONS RELATES TO CATION-MODIFIED PURIFIED GALACTOMANNAN POLYSACCHARIDES PREPARED BY PURIFIYING A CRUDE GALACTOMANNAN POLYSACCHARIDE OBTAINED FROM ALBUMENS OF SEEDS WHICH COMPRISES A MAIN CHAIN COMPOSED OF MANNOSE UNITS AND A SIDE CHAIN COMPOSED OF GALACTOSE UNITS AND HAS MANNOSE TO GALACTOSE RATIO OF 4:1 AND/OR 3:1 TO PRODUCE PURIFIED GALACTOMANNAN POLYSACCHARIDE IN WHICH THE GALACTOMANNAN CONTENT IS 80 WT%, AND PARTIALLY SUBSTITUTING HYDROXYL GROUPS OF THE PURIFIED GALACTOMANNAN POLYSACOHARIDE WITH A QUATERNARY NITROGEN-CONTAINING GROUP OF FORMULA (1), WHEREIN A CATION CHARGE DENSITY DERIVED FROM THE QUATERNARY NITROGEN-CONTAINING GROUP CAN BE OBTAINED IN A SPECIFIC RANGE, AND COSMETIC COMPOSITION CONTAINING THE SAME. FORMULA (WHERE R? AND R? EACH INDEPENDENTLY REPRESENT AN ALKYL GROUP HAVING 1 TO 3 CARBON ATOMS; R? REPRESENTS AN ALKYL GROUP HAVING 1 TO 24 CARBON ATOMS; X REPRESENTS AN ANION; N IS EITHER 0 OR 1 TO 30; AND, WHEN N IS 1 TO 30, (R?O)n REPRESENTS A POLYMER RESIDUE OF AN ALKYLENE OXIDE HAVING 2 TO 4 CARBON ATOMS AND FORMS A POLYALKYLENE GLYCOL CHAIN COMPOSED OF A SINGLE ALKYLENE OXIDE AND/OR A POLYALKYLENE GLYCOL CHAIN COMPOSED OF TWO OR MORE TYPES OF ALKYLENE OXIDE). |
