Course Description

Avoid instability issues in your cosmetic emulsions (O/W, W/O, HIPE, Pickering…) by learning how to quickly select surfactants & characterize emulsions.

Minou Nabavi (Founder, Azad Chem Consulting) will explain the causes of instability (creaming, flocculation, Ostwald ripening…) and share practical strategies to detect & counter the challenges. Topics like how to make an emulsion, assessing emulsion stability, dilution and conductivity test will be addressed in detail.

Why should you view this course?

Guaranteeing the long-term stability of cosmetic emulsions is necessary but difficult and costly. As many factors trigger instability, you may lose too much time finding the right causes and appropriate solutions. Join this online course, and you will be able to:

  1. Master the core fundamentals: Understand emulsion science (Bancroft rule, HLB, etc.) and how to make emulsions.

  2. Troubleshoot faster by detecting early the root causes of instability (flocculation, Ostwald ripening, etc.) in your own system.

  3. Quickly select surfactants and understand how to characterize emulsions with expert tips.

  4. Learn to assess emulsion stability & prevent emulsion degradation.

  5. Reduce the development time of your cosmetics by applying practically-proven strategies.

Who should join this course?

  • This course is ideally suited for cosmetics formulators looking for a way to gain control over emulsion stability for faster troubleshooting and product development.

  • This course is suitable for intermediate level proficiency
