@Vicci C Personally, I don't make products for retail, this is stuff that I have learned and made over the years to help treat various health concerns of my friends, family, and ofc course myself. I got into making products like this with long shelf lives simply whenever I had a health condition pop up, I typically did not have the go-to ingredients I personally go to to help treat said condition, which I found frustrating. So I learned to make 500-gram to 1kg jars of Creams, Lotions, salves, gels, etc., without any active ingredients, just my base products, which I store in the refrigerator, and when needed, I can dispense what I need into my dosage jars/bottles. I always formulate these base products to allow between 15 to 20% additive ingredients (hydrosols, essential oils, fixed oils, etc) to ensure the preservation of the final product is not compromised. When it comes to product and Licensing, Australia is very much unique. If you're making products to sell in your personal Clinic/Online Clinic Shop, as long as you don't make medical or therapeutic claims, and you meet the Australian labelling guidelines, then you can sell products. If making therapeutic/medical claims, then you are subject to the TGA (Therapeutic Goods Administration) in Australia. If going into retail, such as selling items through a third-party store, then the rules are very much different, as your manufacturing space needs to meet certain work health and safety and manufacturing guidelines.
