Acids, bases & pH – oh my! Creating a Burst of citrus clarifying shampoo for oily hair

Let’s take a look at using our pH meters and strips to test, then potentially adjust, the pH of a formula for a citrus-y clarifying shampoo perfect for hot summer days! For some reason, I’m feeling really oily this summer, so I thought I should create a clarifying shampoo full of surfactants, hydrosols, and essential…...

Acids, bases, and pH – oh my! What kind of things that might affect pH?

What do you want to know about ingredients and pH? Let’s get this conversation started!  If an ingredient is water soluble, it has the potential to alter the pH. Glycerin, propylene glycol, hydrosols, floral waters, distillates, preservatives, proteins, humectants – these are all found somewhere on the pH scale, and they can have an impact…...

Video: The effects of pH on the viscosity of Iselux Ultra Mild

Yesterday, we took a look at measuring the pH of an Iselux Ultra Mild body wash formula, then testing it again after adjusting the pH. I forgot to share the before and after video so you can see the thickening from altering the pH alone! I’m sorry I couldn’t show you the pH adjusting bit,…...

Equipment review: Comparing all the meters I’ve tested with an Iselux Ultra Mild body wash formula

Now that we’ve met all the meters I have, let’s take a look at which ones I liked and which ones I didn’t! I find it helpful to gather all my meters and test the heck out of them using the same fluids. You can see this in action in this post where I compared…...

Equipment review: Etekcity pH meter

This one has a strange way of calibrating, by using a screwdriver to alter it if it doesn’t register exactly the reading you want.  This has an all in one glass electrode. It has an accuracy of +/- 0.05 pH. It doesn’t measure temperature and doesn’t have automatic temperature compensation, so if you’re measuring a liquid…...

Equipment review: WeePro pH814 pH meter

This is the worst meter I’ve tested thus far, completely inaccurate and annoying. This has an all in one glass electrode. It has an accuracy of +/- 0.05 pH. It doesn’t measure temperature and doesn’t have automatic temperature compensation, so if you’re measuring a liquid that’s less than 20˚C and higher than 25˚C, it won’t be…...

Equipment review: 7Pros pH meter

I tried this one at Windy Point Soap Making Supplies in 2017, and it was still calibrated in 2018! I can’t remember what we did out of the box, to be honest, but I think the instructions said to soak it for 2 to 3 hours in distilled water. This machine comes with three calibration…...

Equipment review: Dr Meter pH 100 pH meter

I bought this one by accident! I put a few different meters into my Amazon cart, and figured I’d hit “save for later” before checking out, but I didn’t, and it soon ended up at my house.  This one has a glass electrode and measures pH and temperature. It measures pH 0.1 to 14, +/- 0.02…...

Equipment review: Jenco VisionPlus pH630 pH meter

This was the first meter I ever owned, a lovely Christmas present from my husband and mom in 2010, and it served me well for seven long years.  This meter has a glass sensor and reference tube, and the electrode can be easily replaced. It measures temperature – -9.9˚C to 99˚C or 14˚F to 212˚F, the…...
