I’m new here so I first wanted to thank everyone for taking the time to provide such useful information. I’m really thankful to have found this website as being new to making these products, the chemistry is the part that is just over my head a bit, and googling only gets me so far, so I appreciate the expertise. 

I had a question I was hoping someone could expand on with dry clay masks.

I see I do not need a preservative if it remains anhydrous. Does adding essential oils make them no longer anydrous and will then require preservatives?

I’m planning on leaving mine in clay/powdered form for a variety of reasons but would like to use some EO for scent purposes.

It will be different clays with other powders such as hibiscus powder, aloe vera *powder*, rosehip botanical extract powder, mango powder, etc…everything would be in dry form except for the EO and then it would be mixed with water in a separate bowl when using. 

Thanks again for the help.
