Clay preservation
Greetings all
I formulate a natural deodorant magnesium cream.
Based on oils and powders. All served in a jar.
A few questions…
The is green clay presence in my deodorant (no water) - do i need to use preservation? My wish is to avoid it. Even if i i need to change to an airless pump battle. Or maybe even make a deodorant stick instead
Last question i promise.
As my goal to not use any presevetive system i made an experiment and made a deodorant with no clay at all (i put more starch and magnesium instead) and suddenly it didn’t work well. Is clay make the difference so much ?
Thanks in advance -

If your product doesn’t contain water and there is no risk that water may enter it, then you don’t need a preservative.As for why your product did or didn’t work, I don’t know. -
Yes, clay is going to absorb some odors better than starch so it is not surprising that it makes a difference.
Personally, I think not including a preservative in any system is a bad idea.

Thank you for answering ????

You’re using powdered magnesium in your product? It’s incredibly dangerous.

I never heard about dangerous magnesium DEO /: im using magnesium hydroxide

This is why it is important to use proper chemical descriptions. DEA is not cocamide DEA. Magnesium hydroxide is not, what you said, ‘magnesium’. It is as if I said there was “sodium” in a product instead of sodium chloride.

Hello
As long as you don’t have Propylene Glycol or Alcohol in the formula, I don’t encourage adding starch. Even, after some suppliers modified the starch hydrophobically by adding polymethylselsiquioxane to make it more compatible with oil, they used the blend in making Emulsions and SPF which still have water in the formula. May be that is why you said in your post: “It didn’t work well”.
