My midterm went well - an A! - and life is getting less busy, so I thought I'd start this Friday off with some comments you've made over the last two weeks! I love hearing from you, so please comment wherever you can and I'll be sure to see it! Or visit the Weekend Wonderings post and share that thing you've always wanted to know! I do check there first when writing these posts!
this post on honeyquat, Anonymous asks: Would you recommend using honeyquat in a sugar scrub either emulsified or a regular oil based scrub? Would it be hard to preserve? I am using a preservative.
When considering using an ingredient, ask yourself a few questions: Why does this ingredient appeal to you? What kind of ingredient is it, water soluble or oil soluble? Into which phase should you include it? How much should you use? And can you find it easily?
Why do you want to include the ingredient? What is it about honeyquat that appeals to you? It's a positively charged or cationic polymer that offers conditioning properties that behaves as a humectant. It sounds like a great inclusion in an emulsified scrub! It's positively charged, so it will work well with a neutrally charged emulsifier like Polawax or e-wax, or a positively charged one like BTMS-50 or Ritamulse BTMS-225. Sounds like a good fit.

Is it water soluble or oil soluble? It's water soluble, so it would work with the emulsified scrub, but not the oil based scrub. (Click here for more on this topic!)
Into which phase should we include it? The cool down phase! Honeyquat is heat sensitive! (Click here for the post on how to figure out into which phase an ingredient should go!)
How much should I include? Up to 5% in the cool down phase.
Can I find this easily? It depends upon where you live, but I can get it at quite a few shops in Canada now. If you can't, then consider using something similar. For instance, you could use another cationic polymer like polyquat 44 or polyquat 7, but they don't tend to be humectants. You'd get the awesome conditioning power, but you'd have to find something else like glycerin to be the humectant.
So what's the verdict? Yep, you could use it at up to 5% in the cool down phase of an emulsified scrub. If you're making an oil based scrub, it wouldn't work.
There are other things to consider like cost - honeyquat isn't a cheap ingredient - and whether or not you really have a cool down phase in an emulsified scrub - I don't think it gets down to 45˚C - but these are the main ones!
And I'm happy to see you're including preservatives in your oil based and emulsified scrubs! We must always use preservatives in products that might be exposed to water! (Click here for that link!)
this post on my new solid perfume Snapguide, Andrea asks: I took a quick look at your Snapguide and it reminded me that I've been meaning to ask you about the set up of a double boiler. I've seen someone create a double boiler by adding water to a frying pan and setting a Pyrex measuring bowl on top of it. It struck me that this set up defeated the whole purpose of the double boiler since the Pyrex was in direct contact with the bottom of the frying pan. Am I wrong in my thinking?
Yeah, I often forget to put the rack at the bottom of my electric fondue pot/double boiler, but what we're looking for is a more indirect type of heat than putting it in a pot on the stove. The water works to heat the ingredients more slowly than if you put the ingredients in a pot and heated them directly, which is a good thing as we don't want to risk burning the ingredients. Without a rack, the containers might be in contact with the bottom of the pan, but I honestly haven't seen a big difference between having the rack and not having the rack in temperature.
Having said all of this, experience has shown me that using the rack is a good idea. I've lost two really large Pyrex jugs full of expensive ingredients when they cracked on me! Pyrex might be heat resistant, but they can only take so much abuse!
