I have found several base formulas for cucumber peel off face masks.
All of them use Poly Vinyl Alcohol as the film former (which later can be peeled off when dries)
I did my home work and found out that I need to use a certain grade (PVA-224)
I haven't been able to find a proper supplier for this grade of PVA for skincare applications.
Kindly help me out.
