"I'm looking at your shower steamer recipe and you use 7.3% arrowroot powder (of the formulation). I wanted the steamer to last as long as possible (a couple, three showers) and wanted the steamer to be hard. Can I substitute the Bubble Cake Hardener for the Arrowroot? If so, what % of the recipe would you use as substitution? "

Sodium lactate makes a really good hardener for melt and pour soap. That's what I use.

Posted By: Melissa | Date: September 12, 2014

Was this answer helpful? Yes | No

im not sure about using this product to harden M&P bars, but i know that stearic acid will do the trick. the key is to melt it separately from your M&P base as it has a much higher melting point. after its melted just mix it in with your melted M&P base and it will both harden the finished bar and raise the melting temp. hope that helps!

Posted By: Katy | Date: September 12, 2014

I don't think this will make a harder bar of soap. People do add a little stearic acid to mp soap to harden it a bit. Remember anything extra you add can take away from lather.

COMMENTS: This product is pretty much a staple in all my recipes. I include this with my citric acid and find that it gives me confidence that my product will stay stable for shipping. Especially anything that has piped frosting on it. I really like the way it leaves my finished products very hard. It also is great for giving embeds an extra creamy foam and fizz to them.

	"Good Buy"
COMMENTS: Potassium bitartrate (a.k.a. Cream of Tartar, a.k.a. tartaric acid) is expensive. It’s a by-product from wine making and there’s a lot that goes into bringing it from wine vat to consumer, so it’s not going to be cheap anytime soon. But, Cream of Tartar is especially pricey if you buy it from the grocery store. This (which is just a proprietary name) is a more affordable option. Takeaway: Don’t buy the tiny jars at the grocery store. Buy this instead. And— My bubble bars turned out perfectly, first time trying. So fun!

"Great price"

COMMENTS: The BEST price around for cream of tartar. Plus, it's just the potassium bitartrate. Other vendors are using some kind of filler that allows it to work just as well, but I would have to fit three more things onto my ingredient label. My customers want natural and simple, so they are happy and I'm happy with the price.

COMMENTS: I originally used this in bath bubble cakes. The cakes never got hard. It is still a little damp so I am keeping them for myself. The end result is great. I just do not think the cakes will hold up in shipping with out falling apart. I did try it in a whipped soap to use on my Christmas soap. It really helped the soap to set faster and hold peaks better.
