In this post, I wanted to talk about mixing active ingredients in formulations. We want our formulations to do something. This leads to adding multiple actives to approach skin issues from different angles. It can be confusing on what we can add together or not.  Everyone approaches this differently; however, I want to make sure that they are done in a way that makes sense. 

In this post, we are going to do an ingredient guide to Caprylyl/Capryl Glucoside (C/CG). Let me know other ingredients you would like me to do ingredients guides for. 

I was inspired to get this ingredients from the Institute of Personal Care Science (IPCS). They used this ingredient in a "natural" foundation formulation. It suspends pigments and stabilize the emulsion, but without adding viscosity. This is very unusual, typically we need some viscosity to suspend things. ​

I researched this topic a while ago and it occasionally comes up, but I do want to talk about why I still heat and hold. I have seen multiple argument for it. There are some that are based on science and others on bias.

There has been a ton of buzz with Niacinamide. So, I have been getting a ton of questions about how to formulate with it. The main questions was what pH should we formulate it to as there is a lot of contradicting information. I was going to make a series of formulations; however, I needed to address this first. Let's dive into it.

Did you know you can blend emulsifier blends? I touched on why commercial products do it (link), but there are other reasons as well. Some are based on chemistry, and others on aesthetics. That is what I want to discuss in this post. As well as how I would blend emulsifiers.
