Stability Testing And Prediction Of Cosmetic Formulation: How To Avoid Stability Failures?

Stability Testing And Prediction Of Cosmetic Formulation: How To Avoid Stability Failures?

Stability is one of the first conditions that have to be respected when one wishes to develop new Cosmetics products. The purpose of stability testing cosmetic products is to ensure that a new or modified product meets the intended physical, chemical and microbiological quality standards as well as functionality and aesthetics when stored under appropriate conditions. Because the development cycle of cosmetic products is relatively short, and also, in order that the testing activity does not become economically disproportionate in view of the multitude of product launches each year, each manufacturer must have at their disposal tests that are adapted to their activity. In order to obtain stability data in a short period of time, predictive stability test can be carried out.

This training has for purpose to help manufacturers of cosmetic products in the selection and the refinement of the appropriate stability tests. With this scope, a review of the basic requirement for cosmetics stability testing in normal conditions will be done including the techniques that are used in almost all the cosmetics products stability follow-up. Use of advanced characterization techniques will also be analyzed with emphasis in the predictive tests that can give precious indications on the product stability in a very early development stage. In order to avoid stability failure during the product development, theoretical concepts that affect the stability of colloidal systems will be considered by exploring the interaction forces that drive the main causes of instability.

Here is training snippet


Your participation in this training will help you to understand how to identify the critical quality product attributes that need to be followed during stability testing. Technical knowledge on stability of cosmetics will help you to perform in the best conditions stability tests for cosmetics products. The instructor will share his expertise in colloidal science and formulation technology explaining the key formulation parameters necessary to stabilize satisfactorily cosmetics products. The technical review of techniques available to predict stability of products will help to conclude on the viability of cosmetics product in the very first steps of the product development.


R&D chemists involved in formulation development, active & functional ingredient suppliers. Some advanced knowledge in physical chemistry would help to follow this training course.
