Weekend Wonderings: Difference between carbomer vs. acrylates/C10-30 alkyl acrylate crosspolymer? What conditioner can I use for very fine hair? What’s the difference between dilution and ratio?

I keep drinking vast quantities of chicken soup and honey & lemon tea and spraying my throat with echinacea while sucking on zinc tablets, and I think it’s all working. I’m sure the rest isn’t hurting...

Chemistry Thursday: Chemical reactions

by

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

by

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...

(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...
