  HPMC Question

  Posted by Anonymous on October 15, 2014 at 9:23 am

  I always see hydroxyethyl cellulose in leave on applications as the sole
  gelling agent, but I never see hydroxypropyl methylcellulose as a sole
  gelling agent in leave on applications. I only see HPMC in surfactant
  systems (rinse off applications).

  My question is if your going to
  make a gel (leave on) product is there any reason why it is not advised to only
  use HPMC? Would it affect the absorption of ‘actives’ in your product?

  Thanks, Dan V.

  I suspect it’s down to product aesthetics/skin feel more than anything else; HEC gels have short flow and are well suited to skincare, while HPMC gels have long flow and are better suited to surfactant systems
