natrosol™ 250 pharm hydroxyethylcellulose

Ashland webinar:
Optimized design and formulation of liquid and semi-solid pharmaceuticals


on-demand replay

This webinar will address relevant solutions for oral, topical and ophthalmic formulation development that contribute to patient acceptability and clinical efficacy. It will cover the excipient and the process used to achieve a targeted rheology profile for liquids, and the desirable attributes in the development of topical dosage forms.

Join us to learn about mechanical and rheological properties such as viscosity, ease of removal from the container, spreadability on the skin, adhesion retention, the influence of gel former on drug release and drug absorption and more…

key learning objectives:

  • targeted rheology, texture, and stabilization in pharmaceutical liquid and semisolid dosage forms
  • design and formulation of pharmaceutical semisolids and liquids
    • liquids for oral administration
    • sugarless syrups (non sucrose-based)
    • topical gels: rheological and mechanical properties of semisolids
    • ophthalmic solutions: properties, heat sterilization, and sterile filtration of solutions
  • properties of natrosol™ 250 pharm HEC
    • chemistry, features, grades, viscosity profiles and mechanical properties
    • effects of concentration, pH, temperature, and shear rate on viscosity
  • case studies: sugarless syrups, topical gels and eyedrops for dry-eye syndrome
