Chemistry Thursday: Chemical reactions

I see it all the time: Vendors being asked if they have lye in their soaps because it’s a “dangerous” ingredient (which is usually followed by someone saying they have a friend who makes soap and she doesn’t use lye…). If the soap maker said no, there is no lye in her soap, she’d be...

Chemistry Thursday: More ways to measure – molarity

In this Saturday’s Weekend Wonderings, we discussed molarity and % w/v (weight/volume), but let’s get into a little more detail. In chemistry, what is a mole? A mole is how much 6.02 x 10(23) atoms weighs. (The 23 is to the power of as in 10(2) is 10 x 10. So 10(23) is 10 x 10...

Ingredient: PEG-40 hydrogenated castor oil – my methods for testing

I finally found time to play with my PEG-40 hydrogenated castor oil over my holidays, so let’s take a look at the results of my experiments! (I’ve done this kind of testing before using caprylyl/capryl glucoside. Check out the post here!) I chose four different fragrances that I hoped would cover the kinds I might...

Weekend Wonderings: Where to get supplies and how to figure out w/v or molarity!

Apparently holiday time means loads of playing in the workshop, but less time working on the blog. I have so much to write, I admit I’m having trouble figuring out where to start. I’m hearing back from my testers about the eye liner sealant gel and I’m waiting to hear from other testers about the...
