Chemistry Thursday: Some more esters we use as emulsifiers – glyceryl stearate, glyceryl stearate SE, and lactylate esters – with some emulsion theory, including charge stabilization, part 34

Welcome back to this introduction to cosmetic chemistry course! Let’s continue our look at esters by investigating those that work as emulsifiers. We’ll get into some emulsion theory, information on the HLB system, then get into those esters! Today we’re looking at more esters we use as emulsifiers – glyceryl stearate, glyceryl stearate SE, and lactylate...

Let’s try a few different preservatives in a hand & body lotion formula to see how we would adapt them to not lose viscosity – Jeecide CAP-5 formulas (part three)

I thought I’d share some formulas to demonstrate what we covered in our short series on adding ingredients to the cool down phase of emulsions. In part one, we looked at why we added hydrolyzed proteins, mixed tocopherols, actives & cosmeceuticals, fragrance oils, and essential oils to the cool down phase along with some emulsion...

Quick reminder: Don’t forget about the upcoming cold process emulsifier series!

A schedule for the cold process emulsifier series detailing what we're doing each month. This is decorative as the information is in the text

Woo hoo! We’re starting our new introduction to cold process emulsifiers series in October 2025 that’ll be available to Foundation, Formulation, and Innovation subscribers to the site here. Starting October 3rd, 2025, every Friday – for Formulating Friday – we’ll be playing with awesome cold process emulsifiers that’ll help us make emulsions in 10 minutes...

Why are we adding some ingredients to the cool down phase? Why do my emulsions lose viscosity when I add some preservatives? How do I make it not lose viscosity? (Part two)

A close up diagram of a micelle. The oil is in yellow, the emulsifier has a red head, and the OH is the hydroxyl group sticking out into the blue water.

Welcome back to part of two of this short series in which we’re looking at why we might add some ingredients to the cool down phase of a formula. In part one, we looked at why we added hydrolyzed proteins, mixed tocopherols, actives & cosmeceuticals, fragrance oils, and essential oils to the cool down phase...

Basic instructions for lotion making (updated September 2025)

These are what I consider to be the basic instructions for making lotions for most types of emulsifiers, including Polawax, emulsifying wax, Incroquat BTMS-50, Simulsol 165/Lotionpro™ 165, and more. Always check how the emulsifier you’re using needs to be used as this method won’t work for other emulsifiers, like Olivem 1000, Montanov 68 MB, Varisoft...
