Life has become quite insane lately, what with work, the groups, university, crafting, and everything else, I am having a hard time getting into the workshop and a hard time writing up posts. Bear with me as this might continue for the rest of the week. (Long weekend coming up for Canadian Thanksgiving, so I'll have time then to make a ton of stuff!)
Lipidthix to create a butter, I wasn't really all that happy with my rice bran butter. I wanted it to be thicker. So I made a 25% Lipidthix version and really liked it. But here I am with a container with 20% Lipidthix. Could I add more and make it more buttery? Yes!
I added 5% more Lipidthix to the 20% Lipidthix butter and remelted it. I held it at around 65˚C for 15 minutes, then put it straight into the freezer. I left it there about 20 minutes or so - I'm afraid I didn't time it very well as I had things to do, like put away stuff from craft group - then removed the container.
This leads me to one of the more frequently asked questions - can I re-heat this product to include something I missed or to make it emulsify better? The answer is maybe...
If you have a product like this one, an anhydrous product (meaning, a product without water) you can generally re-heat it again. If you have a water containing product - say a lotion, toner, shampoo, conditioner, and so on - you can't. What's the difference?
Ingredients that can handle heat. If you have a product like my rice bran butter, you have two ingredients - the oil and the Lipidthix. Both can handle heat well. So I can heat and hold it at 70˚C and it will be fine. If I added a little fragrance or essential oil to it, those things don't survive heating, and I'd have to add more when it cooled down or accept that my fragrance will be less noticeable.
If you have a product like a lotion or conditioner, you could have many ingredients that don't like heat. Silicones, vitamins, extracts, and preservatives - to name a few things - don't like heat. Re-heating a lotion that failed or one to which you want to add more ingredients, means you're heating things that don't like heat and all kinds of wacky things can happen then! Your preservative might be inactivated, your extracts might break up in the heat and smell funny, your honeyquat will definitely smell funny, and your silicones might turn into a goopy mess. In short, your separated lotion was an improvement on the mess you'll have after heating it a second time.
If you want to re-heat a product, there are two conditions to consider. If your product contains water, you can't re-heat it. If your product contains heat sensitive ingredients, you can't re-heat it. If you have an anhydrous product with fragrance or essential oil, you can re-heat it but you might have to add more fragrance to the mix. (Adding more essential oil might be a bad thing if it contains some active properties, so consider this carefully!)
Why do we heat and hold anhydrous products? (scroll down a bit)
How do we know when to add an ingredient?
