Our Certificate in Natural Cosmetic Preservation is a far more comprehensive course than the single module in our Advanced Diploma in Organic Cosmetic Science, which discusses natural preservation formulation skills.
In our Advanced Diploma in Organic Cosmetic Science, you will learn the important points that need to be evaluated while choosing your preservative system, how to correctly use natural preservatives and how to feel comfortable experimenting with them. We provide a short list of natural preservatives that may be suitable for your formulations.
However, because cosmetic preservation is a very important and extensive topic, we run our in-depth Certificate in Natural Cosmetic Preservation. This course takes you beyond the experiments you'll have conducted in the Advanced Diploma in Organic Cosmetic Science and gives you extensive flowcharts and guidance for choosing the right natural preservative for your needs.
The content between these two courses does not overlap. If you want to learn how to choose the right natural preservative for your needs then we recommend enrolling for our Certificate in Natural Cosmetic Preservation.
