LEARNING OUTCOMES
The aim of the course is for students to understand the basic principles of development, design, compatibility and control study of packaging materials, which are necessary for the creation and production of safe and quality cosmetic products.
The goal of the course is to teach students the different types of materials (using polymer science), which proper cosmetic products will be packaged in them, and to be able to apply their stability and control methods to the final products.
Learning results :
After the end of the course the students will be able to know:
- How to choose (design) the appropriate packaging materials for the respective types of cosmetic products. E.g. baby, sunscreen cosmetics, products for the oral cavity, face, hair etc.
- How to perform the appropriate tests of the stability and compatibility with the product, applying appropriate protocols (methods).
- The methods of control of the packaging materials, upon delivery at the cosmetics factory, in accordance with the Good Manufacturing Practice (GMP) guidelines and the requirements of the National Organization for Medicines.
- The control and evaluation of the final formulations, over time, for the final evaluation of stability (lifetime) of the product.
- How to evaluate, through the appropriate tests (physicochemical, microbiological, testing of packaging materials), the Period After Opening (PAO), which is mandatory to be mentioned on the packaging.
