It's really looking a lot like Christmas! A few questions I've seen a lot in the last little while...

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...

As I mention in 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.

Also from the post 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!

Hi Susan,
Thank you again for hammering home the importance of a preservative. Although I try and keep my products as natural as positive, I will not pass up on a preservative. I'd rather have a small amount of preservative in my product, than a huge amount of microscopic bacteria invading my precious creations! I have used some of the Ecocert preservatives with good results, however am looking for an all round product that when in doubt, I can choose that one (ie: works both in aqueous and anhydrous products, is okay with acorbic acid, etc.). I see you mention phenonip quite a bit, but I have not been able to find it. What supplier do you obtain them from here in Canada? I have tried Voyageur and other local suppliers in Alberta without any success.
Thank you so much for your wonderful blog! It truly is the best addiction hobby ever!!

Dear Susan,

A different question: the ingredients we use result in different skin feels of the end product. Like BTMS or Behenyl Alcohol that leave a more powdery feel and cetyl that leaves a more silky, even waxy feel ... Does this skin feel also mean that your skin is less moisturized? In other words: does the perception part of the ingredient correlate with the functional part of the ingredient?

Thanks a lot in advance for giving this question some thoughts.

B! This is an epic question and one that cannot be answered in a mere comment. I am using this a spring board to talk about our ingredients further. So the down side is that it might take me a week or two to get a few answers up. The up side is that there will be more than one post looking at this question!!!
