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...

Better crafting through chemistry: Esters – isopropyl myristate (IPM) – updated, 2021

by

Original post from 2009!  If you’ve been following this blog for any length of time, you’ll know I’m a fan of isopropyl myristate or IPM. I use it primarily as a dry or astringent emollient to reduce the greasy feeling of other oils in a lotion or lotion bar. You can use it in large...

Esters: Isopropyl esters

by

Isopropyl esters, like isopropyl myristate (IPM), are those based on isopropyl alcohol and a fatty acid. Esters are created by combining an alcohol and an acid, usually a fatty alcohol, like cetyl alcohol, Cetearyl alcohol, stearyl alcohol, or myristyl alcohol, and a fatty acid, like lauric acid, myristic acid, palmitic acid, and stearic acid. Isopropyl esters,...

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)...

How did it get to be almost halfway through 2021 already? It’s supposed to get to 31˚C (88˚F) here today, and that’s just too hot for me, so I’m hiding in the house with my lovely air conditioner in my favourite writing chair with a pup nestled between my knees and wishing for a proper … Read more
