In this post, we will discuss the topics in the title. This post will be an introductory one, as we need to cover some material to understand these in more depth.

Stock solutions are a great way to save time when formulating. Stock solutions are premade concentrated solutions that you add to other formulations. By doing this you can dilute it to the concentration that you want. In the case of hyaluronic acid, it saves time waiting for the HA to disperse and hydrate overnight. Because it is a formulation its self, it will need a preservative.

In this post, I am going to share a detailed introduction to skin anatomy. It is important for formulators to understand the basic skin anatomy. Not just for taking care of it but how it works, how actives affect the skin, and what can go wrong. Of course, we need to remember that we are making cosmetics and not drugs so we still need to be careful. We can not treat acne, we can reduce the appearance. 

There is also a lot of misinformation on the skin that will be addressed in this post. This blog post was based on a free textbook. I encourage you to read it as well. Warning, there may be some images that some may find disturbing. 

I have not made a lotion in a while and I need something for the warmer weather. So I wanted to make a summer lotion. I want this formula to be very lightweight hydrating, and moisturizing.

In this post, I will be detailing how to make your first emulsion. I got this idea from someone asking me in the DMs. You know how you are, thank you so much. This will be geared towards beginners, but I encourage anyone to follow along. If you have not read my post about the basic equipment, read it here. (Link). I do not want this post to be overwhelming, so I will focus on basic techniques here. I would do way more if I were formulating for a business. ​

In this post, we will discuss if we can use a single surfactant in a formulation. I got this question over an Instagram DM and thought that it would be a good post for the blog. So let's talk about it. I would encourage you to read about surfactants.

​Just wanted to share a quick link on vanilla. Vanilla can really affect formulas in two different ways. They tend to turn brown over time, thinning out surfactant formulas. Find out the culprit and how to prevent it. 

I have shared a series of videos that I needed for one of my chemistry lab courses. I thought i would share them as they are quite applicable.

In this post, I am going to be making a facial cleanser with a new surfactant. If you are new to making facial cleansers. Check out my series on surfactants and facial cleansers.

Learn about the different chemical classes for surfactants. As a reminder, surfactants, emulsifiers, and solubilizers are all chemically the same.
