The present invention is directed to cationic nanoparticles, methods to make them, and the use of compositions containing said nanoparticles in personal care compositions or formulations. The nanoparticles are useful in personal care applications and impart antimicrobial properties to home and personal care products containing them. These cationic nanoparticles also contribute useful conditioning properties to hair-care and skin-care products.

Preparation of cationic nanoparticles and personal care compositions comprising said nanoparticles
