Weekend Wonderings: Can I combine cationic ingredients with non-ionic or anionic surfactants?

I’m doing my best to respond to your comments, but considering the other day I made it through three comments before spending a morning researching and writing yesterday’s post on cetrimonium chloride, it’s not as simple as writing a few lines and being done if I want to offer you the most information I can....

Math and active surfactant matter calculators

It seems that everyone wants to calculate the active surfactant matter in their surfactants before adding them to products. I’ve been loathe to suggest any calculators as I think we need to practice math to get better at it, and these calculations are much easier than you think. Example: If we have a surfactant than...

Member exclusive video: Small alterations in the type of fragrance oil you use can make a massive difference in viscosity

It’s pretty incredible to see how changing one small thing – the type of fragrance oil you use – can make such a huge difference in the viscosity of surfactant based products, like bubble baths, body washes, cleansers, and more. In the video below, I used this formula for my ultra bubbly bubble bath. I thickened...

Viscosity!

In these posts on surfactants I’ve been writing recently, I’ve mentioned viscosity quite a lot, so I thought we should take a look at this concept. The easy way to think about viscosity is about the thickness of a fluid. Water has low viscosity while something like glycerin has a higher viscosity. I liked this...

Member exclusive Q&A: What’s that goop in my surfactant bottle?

In the March Q&A, Doris asked: I finished up a litre bottle of Bioterge today and was surprised to find quite a large amount (maybe 10-15% of the total) of a solid/gel/something like that at the bottom of the bottle. I went to get the new bottle I received just a week ago and discovered...
