current questions for skincare formulation
Hello all! brand new to this website but I have been trying to create a face moisturizer that is safe and has a good shelf life. I was wondering about the ingredient sodium anisate and what the dosage for that should be if I want to preserve my face cream containing hyaluronic acid. also how long should I expect it to preserve my product for? for reference here are all of the ingredients I am thinking of using and I would be so grateful if you could let me know if any adverse reactions between ingredients would be present.
-matcha powder(is this good idea?)
-rosehip seed oil
-tea tree oil
-small amount of castor oil
-sodium anisate (%?)
Thank you so much for your help I greatly appreciate it!!!
