Having trouble with Montanov™ & Olivem 1000 emulsifiers? The soaping effect – the impact of shear, viscosity, and melting point with naturally compliant formula (part seven).

by

Welcome to part seven of this series on troubleshooting Montanov™ emulsifiers! In today’s post, we’ll look at the impact of shear, viscosity, and surface tension on the soaping effect in emulsions made with these emulsifiers. This post also applies to Olivem 1000 as they use similar emulsifiers as the Montanov™ series. As you’ve seen over...

Having trouble with Montanov™ or Olivem 1000 emulsifiers? Why more water soluble emulsifiers like these cause more soaping (part six)

by

Welcome to part six of this series on troubleshooting Montanov™ emulsifiers! In today’s post, we’ll take a look at why these emulsifiers soap the way they do – it’s thanks to their increased water solubility! As you’ve seen over the last five posts, the Montanov™ series of emulsifiers – 202, 68 MB, and L –...

Having trouble with Montanov™ & Olivem 1000 emulsifiers? Let’s look at making our formulas less soaping by using solid or simple esters, like Lauryl Laurate or cetyl esters (part five, modifying the formula)

by

Today, in part five of this series, we’ll be looking at the hand & body base formula and modifying them to include esters as our structuring agents. These can have a lower melting point than the fatty alcohols and acids, plus they have lower surface tension, which we know can reduce soaping. This post also...

Shampoo bars: Video link and questions from the Zoom workshop in March 2026! (Formulation & Innovation subscribers) – part two

by
A photo of three shampoo bars on the metal top of a digital scale. From right to left, the largest one is pink; the middle one is pink and smaller because it's been used; the final one is white and it's very small because it's been used a lot.

Thanks for joining me for part two of this short series of posts post-Zoom workshop on shampoo bars! I’m going through the chat from the workshop to answer questions we discussed in the workshop and questions I didn’t get to as there was so much going on, and I want to make sure I addressed...

Zoom workshop on shampoo bars! Link to the replay video! Questions about substituting surfactants, my equipment, using starches, and loads of links to great information! (Formulation and Innovation subscribers)

by

Woo hoo! That Zoom workshop was fun, eh? I’ve been going through the chat and I’ll be answering some of those questions here. I did answer a lot in the workshop, but let’s go through and make sure they’re answered properly with links and such. This post consists mostly of short answers to the questions...
