Testing Stability of Your Cosmetic Formulations

18 Days left to register

Tuesday Jun 23, 2020

Ensure your new or revised formula meets the chemical, physical and microbiological quality standards. Confidently discard sample of your formula batch with stability issues by better organizing & combining your cosmetic product testing (stress testing, micro testing, accelerated / long-term testing…) and identify the formula that pass faster!

Eric Abrutyn will discuss how to achieve reliable results (what test, in which conditions…) & how to assess the impact of external factors (packaging, transport…) on end-product stability.

Why should you attend?

Regulation requires that any cosmetic product has guaranteed stability & integrity until shelf-life. It takes lots of time to run stability tests, and we all want to avoid as much as possible stability issues in the final development steps… which would imply to start everything all over again! That’s exactly why we are offering this course, because (too) many formulators still run stability tests by habit and there is a better way! Join & learn to:


  1. Define reliable & efficient test plan to best combine predictive tests (accelerated / long-term testing, micro testing...) depending on your formulation (highly viscous...)

  2. Better assess shelf-life of your product by reviewing how to play with parameters that can affect or accelerate stability (light, temperature, moisture, agitation…)

  3. Minimize the occurrence of “unfortunate surprise” by understanding the effects of test equipment and packaging (interaction with container material and label...)
Testing Stability of Your Cosmetic Formulations

Who should attend?

Cosmetic Formulators, technicians, R&D people and Process developers

Course Outline

  1. Defining and understanding stability
    • Definition
    • Regulatory guidelines
    • Types of stability (preliminary, initial, pilot plant, plant trial)
    • Parameters affecting stability

  2. Predictive tests
    • Types of stability tests (accelerated/long term, stress studies...) and how to combine them
    • Test conditions
    • How to choose the right test for your formulation (solid, semisolid, liquid): you shouldn't do it by habit!

VERY GOOD ! The presentation made us think of 1 or 2 new ideas as complementary items in our safety assessment protocol.
