N-Hance™ HP Series hydroxypropyl guar
Odor: odorless
Use: N-Hance hydroxypropyl (HP) guar is a nonionic polymeric thickener and film former. It is often specified in personal care formulations to take advantage of its characteristic high level of lubricity as well as excellent salt and alcohol tolerance in aqueous solutions. N-Hance HP guar is offered in a buffered self-hydrating grade (HP-40S) as well as a non-buffered grade (HP-40). Solutions of HP guar will be slightly hazy.
