@Sam0794, if you truly are new to formulating, you should probably leave chemical exfoliants for when you have some more experience.
Granted, handling and formulating with fruit acid extract is not as worrisome as handling glycolic or lactic acids, but it can still be a difficult thing to do safely for a novice.
So before you start this endeavors, I would like to ask you the following:
- How are you measuring your ingredients? Do you have good quality scale/balances that allows you to measure “at least” fractions of grams (on one end), and “at least” hundreds of grams (on the other end)?
- What tools do you have to measure the pH of your final product, down to 0.1 units of pH?
- What other ingredients are you planning to use? The most basic AHA liquid could contain only water, AHA, pH adjuster, preservative. From there you can add other ingredients, humectants, emollients, rheology modifiers, claim (or fancy label) ingredients that don’t do much; the AHAs will do all the hard work, but you added 0.01% of Internecivus raptus extract, so now you can make the unsubstantiated claim that it was the extract that did its job).
However, not all ingredients will be ultimately compatible or stable for long at your target pH.
It doesn’t take much to transform a lightly exfoliating overnight formula to a low-strength chemical peel.
