Warming scrub
Hi All,
I’m currently working on a warming scrub similar to the below body scrub that’s on the market. My product has to be oil-free and can only contain vegetable or mineral derived ingredients. For this reason, my only options for solvent is Glycerin (99.7%) and Magnesium Sulfate Anhydrous for warming.
The issue that I’m observing is that the product is thickening considerably over time. One of my colleagues mentioned that Magnesium Sulfate Anhydrous is taking moisture from Glycerin. This is the first time I work with this raw material so I’m wondering if this is what could be happening? Other ingredients in the formula are cetearyl alcohol/cetearyl glucoside for thickening and coconut shell powder. I would like my scrub to maintain the same viscosity throughout its shelf life…any thoughts on what could be happening?
Thanks!

It doesn’t exactly sound “similar” to the Sephora product, frankly. First, unless you list the formula, we can’t help you. Having checked the Sephora LOI it appears to me that it is not in proper order.

Sorry, when I said similar, I meant an anhydrous scrub with warming effect.
Formula:
Glycerin q.s.
Magnesium Sulfate Anhydrous 15%
Montanov 68 (cetearyl alcohol, cetearyl glucoside) 2%
Silica dimethyl silylate 2.5%
Coconut Shell powder 1.5% -
Sephora doesn’t use glycerin, so why not try another solvent? Then you’ll probably have the answer..
