Combining emollients: Part seven, part one: Interfacial tension and polarity!

Welcome back! Join me today as we take a look at how interfacial tension and polarity of a molecule can influence the spreading values, viscosity, and more. Then we’ll take a look at molecular structure, shape, size, and weight tomorrow before practising all this wonderful stuff we’ve been learning in this series! Let’s recap!  Click...

Q&A: What can I substitute for polyquaternium 7 in a conditioner bar?

In the December Q&A, Sherri asked, I was hoping to make conditioner bars for my girls’ stockings, but I’m almost out of polyquaternium 7, and my usual Canadian supplier is sold out. Are there any substitutions I can use? Quick note: I’ve started a Q&A post on conditioner bars that you’ll find pinned to the right...

Combining emollients: Part six, viscosity and surface tension – part two, the worksheet!

Welcome to part two of our look at the relationship between viscosity and surface tension as we review both concepts, then work through a worksheet where we combine the two concepts before we make a few products with these ideas in mind. In section one, we took a look at the concept of combining emollients...

Combining emollients: Part six, viscosity and surface tension – part one, reviewing the concept

Welcome back to our series on combining emollients! In this part – part or section six – we’ll combine the concepts of viscosity and surface tension to see how they affect the spreadability, spreading values, sensory characteristics, and other properties when it comes to using emollients in our products. In section one, we took a...
