Creating formulas with isopropyl palmitate (IPP): Silky, smooth, non-greasy, emulsified lotion bar for the shower

by

Over the last week, 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. We met isopropyl myristate (IPM), then made a less greasy, lighter anhydrous whipped body butter with shea, then we met isopropyl palmitate (IPP), which you could use...

#alltheingredients: Isopropyl stearate (IPS) – an isopropyl ester

by

Isopropyl stearate (IPS) is an isopropyl ester related to isopropyl myristate (IPM), isopropyl palmitate (IPP), and isopropyl isostearate (IPIS). It’s a low viscosity, non-greasy, hydrophobic (water-hating) ester derived from stearic acid. To learn more about these isopropyl esters, check out this post on isomers and this post on comparing isopropyl esters! Click here to learn...

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...

#alltheingredients: Isopropyl palmitate (IPP) – an isopropyl ester, updated 2021

by

Isopropyl palmitate is related to isopropyl myristate (IPM), the difference being IPP is derived from palmitic fatty acid (C16) and IPM is derived from myristic fatty acid (C14). (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...

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

by
A cup of isopropyl myristate. It's being poured from a bottle into a plastic shot glass that sits on a brown coffee table.

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...
