The role of antioxidants in protecting formulations
Hi everyone! Long time no see!I’ve been thinking for a while about the role of antioxidants in protecting formulations and I’ve recently dealt with some interesting questions on this topic.1 - Do they also act to protect the aqueous phase, or are they limited to the oily phase?2 - Are there natural options on the market to meet the “natural-lovers” that appear so often searching for these ingredientes?3 - Is there any “improved” action when used in association with chelating agents? (I can hardly find technical materials on, for example, BHT - I imagine it’s because it’s a commodity - and the only one I had access to said “best used in combination with EDTA”)
4 - What examples besides BHT, Tinogard TT (Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate) and Vitamin E do you know and use?
In all of the above cases, the focus is only on the formulation, not the skin.Thank you for your time!
