I seek the same unswer,o more logically,it will be added at the end of formulation, im just guessing,but my question how to konw how much ,in un example i found after i have done my calculation that i sould add almoust 7 % of buffer solution , i found this too much ??

If i can add a question,I’m new in formulation,so this oil micellar based,will contain only oils??? Plant oil??

I’m trying the same to make the same formula,and i found that urea dissolve well in glycerine,but i m concerned about preservatif, does this amount of 5%glycerine,and 10% of urea need to be preserved, and if it is so.wich preservative will work ??

Thanks a lot for your answer, i think i would refer to add a preservative, may be paraben complex?? Another question please,if we are solublising the urea in glycerine,then the aqueous phase will be 45%, or we will just considering the amount of glycerine?? Im beginner ????

Without using an emulsifier?? And wich amount of glycerine we use,what about preservatif?? I m dealing with the same issue
