Acids, bases, and pH – oh my! Creating a light, non-greasy summer weight lotion with Varisoft EQ 65 (part two, the oil phase)

Let’s pick up where we left off yesterday in creating this light, non-greasy summer weight lotion using Varisoft EQ 65. We figured out what we wanted to include in our water phase, so let’s take a look at the oil phase. As I mentioned yesterday, I’m using Varisoft EQ 65 as the emulsifier to create a…...

Acids, bases, and pH – oh my! Creating a light, non-greasy summer weight lotion with Varisoft EQ 65 (part one, the water phase)

I hate summer so very much, but I’m handling it far better this year because we just had central air conditioning installed, and it can get so chilly, I need to put on a light cardigan. (I’m the type who wears shorts all year ’round, so this is a big big deal!) But I know…...

Creating a light hydrating summer body milk with Olivem 1000 – part one

On Thursday, we met a new-to-me oil, tamanu oil! Let’s take a look at how we might use this in a lotion! As a note, I find the smell too strong to use in huge amounts in an anhydrous product, like a lotion bar or whipped butter, but you could certainly use it in those…...

Emulsifiers: Glyceryl stearate SE

Glyceryl stearate SE seems like an old school emulsifier – we can use it with the HLB system as it has a value of 5.5 to 5.9 – but it makes lovely light, fluffy, non-greasy lotions with an elegant skin feel. It’s a modified version of glyceryl stearate, so it can be used as the sole…...

Formulating Fun! Modifying the Saje Psoria Ease Healing Treatment Lotion with a fatty alcohol

Way back in January, I shared with you this potential duplication for Saje Psoria Ease Healing Treatment Lotion. There were four parts to this series – analyzing the ingredient list, part one and part two, a prototype formula, then a modified formula – but I had to add a part five! I really liked that formula, which…...

Adapting formulas to use ECOcert ingredients: Simulgreen 18-2 – using fatty alcohols (updated)

Originally posted to Patreon on Dec 7, 2017 at 4:59am I don’t think it’s any surprise that I really love this emulsifier, Simulgreen 18-2, given I’ve been formulating with it like crazy lately. I started working with it back in June 2015, and it’s become one of my favourites. Let’s see how we can use…...
