Personal care products cationic polymers

Cationic and hydrophobe modified polysaccharides are preferred excipients for personal care products since they are substantive (adherent) to anionic or hydrophobic substrates (skin, hair, mucosa), hydrophilic, film forming, compatible with many therapeutic agents, nonpenetrating, and nonirritating. Polymer JR and Quatrisoft (Figure 1), are two such materials... 

Nearly all hair care products incorporate one or more cationic conditioning agents, where the latter can be either cationic surfactants or cationic polymers. The cationic surfactants can be further divided into four major classes, i.e. alkylamines, ethoxylated amines, alkyl imidazolines, and quaternaries. The quaternaries are the most widely used in the personal care industry because of their strong affinity to the hair fibre surface.
