Creating formulas with isopropyl myristate (IPM): Anhydrous whipped body butters with shea

by

Over the last few days, we’ve learned that the isopropyl esters are light, fast spreading, non-greasy, and silky, and they can be used with emulsified or anhydrous (without water) products. One of the easiest ways to see how isopropyl myristate (IPM) feels on your skin is to make a simple anhydrous formula and substitute it...

(Click here for the chemistry of esters!) Since we’re a little more familiar with IPM, we’ll end up contrasting and comparing the two at some point, so...

Chemistry: Isomers and how they relate to the isopropyl esters…

by

I thought I’d share a little about the chemistry of isomers before we get into isopropyl esters, like isopropyl myristate, isopropyl palmitate, isopropyl stearate, and isopropyl isostearate. I have to point out that you don’t need to know all of this to enjoy making products or using ingredients like isopropyl myristate (IPM) or isopropyl palmitate (IPP)...
