Ok, a bit of back story as this is a bit different.
My face is v. sensitive to cleansers and the only thing I'm happy with is water and occasionally an oats wash, literally smearing my face with oats. As you can imagine, this is rather messy, so I started putting the oats in empty paper tea bags as a single use face wash. The teabag goes in a cup with a little boiling water whilst I'm cleaning my teeth. I then add some cold water and wash my face with the tea bag. This is awesome.
Over time I've added some other ingredients including various dried herbs/petals etc and a smidge of oils and mild surfactants.
My friends/family/customers eventually found out and asked to try out my Tea Face. I've handed out samples to some people. They love it too.....but.....no matter how much I told them that it was a single use product as it has no preservatives, I get comments like "It felt like a waste to only use it once, so I kept it in the fridge and reused it" ARGGH! Luckily for me, the bag disintegrates after a couple uses, but I can't help but think that someone will use it, leave it out for a few days and then use it again.
So, how to add a preservative to this product?
I'd be worried about proper dispersal with a powder. I've also thought about using an oil based preservative and adding it to the small amount of oil I add
to the product.
What are your collective thoughts my lovely people?
