Hello, I do not recommend, but if you want to try to adjust the formula. can do but must have expertise and understanding To check the stability of the formula The formula will definitely not have the same stability because Ethyl Ascorbic acid affects the pH of the formula and Perfect-C has an effect on transparency. and the stability of the emulsion because it is oil
