Chemistry Thursday: The difference between solubilizers and emulsifiers redux

by

In this post on solubilizers, someone asked: I still don’t get the difference between a solubilizer and a emulsifier. If I mix propylene glycol (in substitution for the surfactant), cetyl alcohol or stearic acid in water, will I be getting a lotion?  The quick answer is no because there’s nothing in your question that is...

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?

by

Still suffering from this horrible cold, although my throat is feeling better and my skin doesn’t hurt so much. 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...
