MSM is hygroscopic - meaning it is a humectant - and we buy it in as a water soluble white powder so it's easier and less stinky to use than sulphur powder. We add it in the heated water phase of our lotions and other creations so it will dissolve properly. When added to lotions and other emulsified things, it can cool down and leave shards behind that are most unpleasant on the skin if not properly dissolved (it's a lot like allantoin in that way). Start at 1% and see how you like it in your products - you can use it up to 5% for products intended for oily hair or skin related products, up to 10% for pain relief.
You cannot use it in an anhydrous product (non-water, oil only containing product) as it is water soluble. This means you cannot put into a lotion bar, whipped butter, balm, or salve. You have to use it in a product that contains water, like a lotion. If you check out the newbies section of the blog, you'll see a nice basic lotion that could easily accept MSM into it. Start with 1% in the heated water phase to see what you think of it. Make a small 100 gram batch of lotion and see what you think of it before making a larger batch and adding more MSM.
Let us know how it turns out!
Phenonip, fie_jia asks: Can i use optiphen plus or germall plus for my lip product recipe such as lip stain that contain water ? Or can you suggest me a better preservative for lip product that contain water ? Thank you : )
If you want to know more about a preservative and the information isn't here on the blog, a great idea is to do a Google search for "preservative name" + data bulletin +lip safe. You'll find quite a lot of information. If it isn't immediately obvious, take a look at the products for which they suggest the preservative, and you can get a better sense of how to use it.
No, you can't use liquid Germall Plus in lip products. I can't find anything about Optiphen Plus being lip safe or not - I would say "not", based on the data sheets I found that don't include any suggestions for using it in lip products - but I have found quite a lot about parabens being lip safe. So you might want to look into Phenonip or Germaben II. Optiphen might also be safe. I think you'll have to do a bit more research about one of these preservatives before putting it in a lip product.
