Combining emollients: Section four, viscosity – Creating an anhydrous body oil (part three, creating a formula)

by

Welcome to section four of this series on combining emollients! In this part of the series, we’ll be making an anhydrous body oil (one without water) with all the information we have about viscosity and spreading values to see how those might impact the choices we make to create a smooth cascade of emollients with...

Preservatives: Choosing preservatives that work with cationic emulsifiers

by

In the previous Newbie Tuesday and Formulating Friday series/course, we took a look at different preservatives we could use instead of Germall Plus liquid. For the Ritamulse SCG series, we considered those which would work for anionic or negatively charged emulsifiers; for the Polawax, e-wax NF, Phytomulse, or Natragem EW series, we considered those that...

Combining emollients: Section four, viscosity (part four) – Spreading values and viscosity

by

Welcome to section four, part three of this series on combining emollients! Today, we’ll practice what we’ve learned so far about viscosity and spreading values and everything else! Part one of this section, introduction to viscosity! Part two: Looking at specific emollients, then considering the impact of fatty acid carbon chain length and saturation on...
