We've also listed other suppliers who stock all or some of the ingredients in the list below. Keep in mind that not every supplier will stock every single ingredient (unfortunately buying ingredients is not like going to the supermarket!), so you may need to shop around. If your chosen supplier is out of stock of the ingredients, then just try a different ingredient that appeals to you by following Lesson 8, follow the supplier’s usage recommendation and chat to us during our live Q&As to find out if there are any restrictions. Know of a brilliant supplier who you think your fellow Masterclass students should know about? Post up your recommendations in our Facebook group and inspire your fellow formulators!
