Patent ID: 8449868

Claim:
A personal care composition comprising (a) an effective amount of at least one cationic nanoparticle of formula (I) wherein said cationic nanoparticle core comprises an inorganic material and where A is an organic substituent covalently bound to the core nanoparticle surface and containing at least one cationic group L; B is an organic substituent covalently bound to the core nanoparticle surface and containing at least one cationic moiety G; C is an organic substituent covalently bound to the core nanoparticle surface containing at least one functional group Z; a is a number from 1 to n a ; b is a number from 0 to n b ; c is a number from 0 to n c ; where the sum of n a +n b +n c is a number from 1 up to n l , where n l is limited by the geometry and surface area of the core nanoparticle and the steric requirements of the respective substituents A, B, C; and (b) a cosmetically acceptable adjuvant.
