#alltheingredients: Isoamyl laurate and isoamyl cocoate – isoamyl esters, aka Naturderm IL, Gosulin IL

We met isoamyl laurate the other day – also known as dermofeel® sensolv – so let’s meet isoamyl cocoate, then take a look at the ingredient that might be called Naturderm IL or Gosulin IL. Isoamyl laurate only consists of the C12 fatty acid, lauric acid, while isoamyl cocoate has an array of fatty acids...

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

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...
