inny Posted July 19, 2021 Share Posted July 19, 2021 Hello, I am considering using the Stephenson bath whip for a whipped soap and a foaming sugar scrub, however, I’ve realized that the base does not use a broad spectrum preservation system… I loved the base I ordered, however, now I’m concerned about using it. I was also considering using the base from Crafter’s Choice (which does have broad spectrum preservation), however, it just wasn’t as good . I really wanna stick with the Stephenson one. Could I add some extra preservative to the base in order to make it safer? However, since I don’t know the exact measurements for the preservative added, I’m afraid I might accidentally add too much.. Quote Link to comment Share on other sites More sharing options...
TallTayl Posted July 19, 2021 Share Posted July 19, 2021 Hi! Welcome, and great question. I would be inclined to drop a quick message to Stephenson to ask. They use phenoxyethanol which can be considered broad spectrum when combined with EDTA. I like reading Paula’s Choice articles when considering options: https://www.paulaschoice.com/ingredient-dictionary/preservatives/phenoxyethanol.html Phenoxyethanol is a stand alone preservative for many formulas when combined with EDTA (as this formulation seems to be). https://library.essentialwholesale.com/preserving-natural-cosmetics-with-phenoxyethanol-and-edta/ It can be combined with others, such as ethylhexyl glycerin (caprylyl glycol). Here’s one pre-combined to give you an idea of the intention of the combo. https://naturallythinking.com/phenoxyethanol-ethylhexylglycerin For others following along, if this is the one being compared to from WSP, you can see their choices of preservative at the end. Looks like Germall Plus to me. The formaldehyde donor turns a lot of people off from this preservative system. Quote Link to comment Share on other sites More sharing options...
NightLight Posted July 20, 2021 Share Posted July 20, 2021 I would contact the manufacturer. I would use product as is, unless you’re adding things that might make base a bacteria soup when wet. They do design the base with safety in mind and always tell customers not to add water into container. Quote Link to comment Share on other sites More sharing options...
