Jesus … it’s the limonene. You’re lucky only a few people are experiencing a burning sensation.

i’m thankful to you all for taking out ur time and reply !… @belassi .. i m not so sure as we have put bentonite in other masks and no issues et al.. may b the acid structure is different here which doesnt burn in case of bentonite.. and with limonene only we tested it and didnt experience any burn…so far we believe and after hit and trial come to the conclusion its phenoxy…any suggestion friends wat preserative we can use instead of phenoxy which doesnt burn or can we neutralize phenoxy in this case with ethyhexylglycerin or any other?

@ngarayeva001.. Should i use propyl or methyl or combination of both and upto what percentage we should test it?

I would advice to buy a ready mix. I use Paraben DU (Propylparaben, methylparaben, diazolidinyl urea, propylene glycol) by makingcosmetics. I like it because it doesn’t change viscosity of the product, easy to use, effective at a low % and has less strong odour than preservatives with phenoxyethanol. Regarding percentages, follow recommendations of the supplier (0.3-1%). A product pacakged in an airless pump requires less preservative than a product in a jar. I don’t have a lot of experience with clays, but I heard it’s difficult to preserve them, pkus you have a lot of other food for bacteria in your formula, so maybe you should use close to the max recommended amount. Do some research on preserving products with clays.
