It's definitely looking like Christmas these days, and I'm so happy that you want to give bath & body products to those you like and love this holiday season! I thought we'd take a moment to look at a few questions I've been posed in the last few weeks...
What you need to know about making any products (part one), water soluble ingredients are those that dissolve and mix well with water. This includes things like aloe vera, hydrosols, floral waters, and other water based ingredients.
Oil soluble ingredients are those that dissolve and mix well with oils, butters, esters, and other oily ingredients.
The only way to bring the two together is to include an emulsifier. No emulsifier, no coming together, and we end up with the oil floating on top of the water or end up with water seeping out of the oil.
You cannot dissolve water soluble powders into oil based products. For instance, you can't mix something like chamomile powder into an oil because it simply won't mix. This powder is designed to work with water soluble things, and the only way to incorporate that powder into this oil is to make a product that contains water so you can dissolve the powder. If you really want to use an extract in your anhydrous product, consider some of the oil based extracts you can get at shops like Brambleberry or Formulator Sample Shop.
Back to the very basics: Lotions
It's time to make a lotion!
Creating a whipped anhydrous butter
What you need to know about making any products (part one), if you are using water in your product or if your product will be exposed to water, you must use a preservative. There are no exceptions to this rule. None. Nada. Nil. Zip. Zero. Zilch. No exceptions.
Oh wait, there's one exception...Nope, there isn't. That was a trick. There are no exceptions.
If you'd like to learn more about preservatives, check out this post - what you need to know about making any products (part two) - as a starting point. I have an entire section devoted to this topic because preservatives are so important in our products, and you can learn more about each preservative there.

Have fun formulating!
P.S. Have I mentioned lately how addicting making bath & body products can be? I better mention it now. It is very addicting. You will find yourself drooling over new butters, trying out new oils, and ordering a little bit of everything off suppliers' web sites just to give it a try. Do not worry: This is normal. You're just falling in love with the best darned hobby in the world!
