C18-22 Hydroxyalkyl Hydroxypropyl Guar

What is C18-22 Hydroxyalkyl Hydroxypropyl Guar?

C18-22 Hydroxyalkyl Hydroxypropyl Guar originates from guar gum extracted from the seeds of the guar plant (Cyamopsis tetragonoloba). It undergoes chemical modification where hydroxypropyl groups and C18-22 hydroxyalkyl chains—derived from fatty alcohols—are grafted onto the guar polysaccharide structure. This results in a hydrophobically modified, water-soluble polymer primarily featured in rinse-off hair care products such as shampoos and conditioners, with occasional use in skin cleansers and lotions. Functionally, it adsorbs onto hair cuticles and skin surfaces, creating a lubricious film that minimizes friction between strands or against skin, enhances slip during application, and imparts a smooth, conditioned feel without heavy buildup.
