Creating a toner, Susan asks: To my question, which may seem obvious, but I just want to make sure. When you list a % for a botanical extract, such as chamomile or green tea extract, is that in the powdered form, before it is hydrated? So this recipe for toner would be 0.5% powdered chamomile extract? Just want to make sure as I have made some fails in the past using extracts incorrectly in the recipe when it was not clearly stated. A lovely lotion I made turned ugly when I added green tea extract - the author apparently had used a liquid form.
Yes. When I add 0.5% powdered chamomile extract, in a 100 gram toner I would add 0.5 grams of powdered chamomile extract to the toner. This is powder straight from the container.
Liquid extracts and powdered extracts generally have very different suggested usage rates. For intance, I have liquid extracts I can use up at up to 10%, whereas I've never seen a powder that was to be used at more than 0.5%. If you used 10% powder, your lotion would be a big, green, mushy mess!
Always check with your supplier for their suggested usage rates. They are the experts on this topic, and they should know what the manufacturer of that powder recommends.
