I added methyl paraben to a base before running it through the food processor. Is methyl paraben like SB in that it takes several days to work it’s magic? If I want the base to stay exactly how it is can/should I store it in the fridge while I wait for it to work or would room temperature, or unregulated she’d work equally as well?

Since it’s an anti fungal, and funguses take a while to start growing, I’ve never worried about it.

Throw it in, mix it up, walk away.
