What is it?"Lotioncrafter Serum SE is a proprietary blend of self emulsifying silicone fluids designed to make the creation of water-in-silicone emulsions (or serums) simple. Along with Lotioncrafter Serum SE, serums are created and stabilized using a sodium chloride/sodium citrate buffer. This reduces interfacial tension and improves freeze-thaw stability, as does the addition of glycerin and/or glycols (dipropylene, propylene or butylene glycol). These also contribute to increased preservative efficacy."
This is a great way to get loads of cosmeceuticals or actives into your product, and it's fantastic to use underneath make-up. In fact, if you're looking to make an under make-up primer, this is a great product!
You'll want to add a sodium chloride (salt) and sodium citrate buffer to it, so don't forget to order the latter when you order this emulsifier. Oh, and get yourself some propylene glycol as well. I've tried it with 10% glycerin, and it was a bit sticky for my tastes!
How do we use it? You can get all your ingredients together and follow the instructions. The down side is that you have to mix it for 10 to 15 minutes with a hand mixer, so if you have a stand mixer, all the better! (Trust me, your arm will get tired!) It is made cold with no heating and holding, so make sure you are using distilled water and avoid using a lot of botanical ingredients to preserve it well.
I'm linking to a few sample recipes before I share what I've made with you tomorrow. The process is fairly similar for each one, so if you want to go nuts and make one tonight, just follow the easy to use instructions Jen from Lotioncrafter has included in this basic water in silicone serum recipe!
