preservative for dry shampoo
Hi all,
It’s the first time I make a dry shampoo and was wondering what’s the best preservative to use.I will mainly use corn starch and this will be a non-aerosol. I can’t use parabens, formaldehyde donors or IPBC.What should I consider when selecting a preservative for a powder?Thanks in advance -

how hygroscopic is your dry shampoo, and how likely is it to be exposed to moisture during the manufacturing and production process?

Can you use ethanol?
