Preservative for Shea Whip Butter ?

Posted by prow18 on April 1, 2024 at 3:34 pm

I’m looking to make an oil based shea whip butter formula and am looking for some direction on preservatives. Currently I’ve been looking at phenoxyethanol. Would this be a good choice? Would tocopherol or Rosemary Oleoresin be something to add in addition to Phenoxyethanol or would they be redundant?

Thanks!

Aloha…

First… ROE and Vit E….are not preservatives AT ALL (that is just mommy blogger lore that has refused to die….decade after decade). Sometimes as antioxidants, they are said to ‘preserve’ oils….or keep them from going rancid. So, you have to watch the lingo in cosmetics. Secondly….they would not be redundant with phenoxy…since they do not do anything in common with the latter. However…they might be redundant with each other…. albeit I use both…in all formulas that contain natural oils.

A little hard to answer your question….without knowing….is there ANY water at all in your product?

If you can clarify that….you can get better answers. ????

@Graillotion

You are correct, I over-applied the term “preservative”. I understand ROE/Tocopherol will only help slow rancidity, I just wasn’t sure if Phenoxy did the same.

It’s an oil formula, no water.

Any suggestions on % for ROE/Tocopherol?

  .1% will be quite a plenty, on the ROE or E. Don’t get caught up in internet lore….or E will do the opposite of what you want…as level rise.
  
  If you are making for yourself…and keeping it away from any splash-in water…or high humidity bathrooms… microbial preservation would be optional. If you are consider selling…. Always remember….customers are utterly filthy….and NEVER follow directions. Hence, keep that in mind…as well as how good your insurance is. If you add a preservative….you might be putting yourself on an island. Just depends on your customer target. We are assuming no added bug-food.

Anhydrous oil, why do you need an antimicrobial preservative?

  So not necessary?

    No water? Nothing in ingredients? Does it take up water in a humid bathroom?

        If no water - as in none added and none in ingredients - doubt you need a preservative. You still need to test for content - numbers of microbes.
