#alltheingredients: Isoamyl laurate – an isoamyl ester (aka dermofeel® Sensolv)

by

I bet you thought isomer month was over, but wait – there’s more! Let’s meet isoamyl laurate today before meeting it in combination with isoamyl cocoate tomorrow! Formulator Sample Shop was kind enough to send me a sample of this awesome isoamyl ester, Isoamyl laurate, also known as dermofeel® Sensolv, a polar oil that works...

#alltheingredients: Isohexadecane – C16 hydrocarbon (light, non-greasy, silky feeling emollient)

by

It really feels like it’s isomer month there on the blog! Let’s take a look at a new-to-me hydrocarbon, Isohexadecane (C16), the isomer of hexadecane! But first, if you aren’t familiar with hydrocarbons, check out these posts found in the emollients section of the blog! These are long chains of carbon and hydrogen atoms without...

#alltheingredients: Isopropyl isostearate (IPIS) – an isopropyl ester

by

Isopropyl isostearate (IPIS) is an isopropyl ester related to isopropyl myristate (IPM), isopropyl palmitate (IPP), and isopropyl stearate (IPS). It’s a low viscosity, non-greasy, hydrophobic (water-hating), medium polarity, water white, odourless, and clear ester derived from isostearic acid. We use it as a skin conditioning and occlusive emollient that’s more water resistant than isopropyl myristate...

#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...

#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...
