NEW E-LEARNING! Stability Testing for Cosmetics

CTPA launched a new e-learning in its Online Learning Platform on stability testing for cosmetic products.  The e-learning can be accessed here.

This e-learning was developed with expert members in this field, and provides a comprehensive training on stability and compatibility testing for cosmetic products, outlining industry’s best practices in this area.  It includes two modules:

  • Module 1 provides a comprehensive description of best practices in stability and compatibility testing, explaining how these tests are carried out and key consideration for test design.
  • Module 2 covers how to interpret the results from stability and compatibility testing, how to calculate the shelf life of the product and assess the Best Before End (BBE) date or Period After Opening (PAO).

This resource can be accessed for free by CTPA members; it is also available to non-members at £95+VAT.
