Presented by Perry Romanowski
Stability testing is one of the most common types of testing cosmetic formulators perform, and yet it’s not a topic covered in college. Knowing what stability testing is and when and how to conduct tests is critical for anyone who wants to be a successful formulator. In this free webinar, Chemists Corner blogger and Prospector Contributing Author Perry Romanowski will give you the information you need to properly perform stability tests on your cosmetic formulations, including:
- The philosophy behind stability testing.
- The basic format of a stability test.
- The types of products that need to be tested.
UL offers a wide selection of testing and verification services, including cosmetic stability testing. Find out more here…

Perry: Hello, everyone, thank you, Trey, for that, and thank you, UL Prospector for setting this up. I’m really excited to talk to you about today’s topic, Stability Testing. And so in this presentation, we’re gonna be talking for about a half hour, and along the way, we’ll be taking questions. There’s a question box there so you can put in your questions for me to answer later at the end. So let’s begin with stability testing. Just a moment, there we go. Actually, let’s begin with a little bit about me since you may or may not know me, Trey did a nice introduction there, but currently, I’m the vice president of a company I started called Element 44, which I provide cosmetic science information, and I do a little bit of consulting. And so, you can contact me through my website chemistcorner.com. For years I was a Cosmetic Chemist, a Formulator. And the stuff that I’m gonna present to you today comes out of my experience as a formulator because I had to do these types of tests all the time. Stability testing isn’t a thing that anybody learns in college or while you’re studying chemistry, but it turns out to be one of the primary activities that you spend your time as a formulator doing. It’s extremely important both in regards with creating new formulations, and with regards to keeping yourself legal in terms of having the proper background information for your formulations that are sold on the market.
In addition to being a Formulator for, geez, almost 17 years in hair care and skin care products, I’m an author, and you might be familiar with “Beginning Cosmetic Chemistry,” which is a book I co-wrote with Randy Schuler. Which just gives you an introduction to the cosmetic industry, and you can find information about testing, like stability testing in there, but about raw materials, formulating, and that sort of thing. So that book is still available I encourage you to check that out. And also, here’s my website Chemist Corner, this provides more detailed information that formulators would wanna know. And so I encourage you to check out that resource, most of things there are free. And I just wanted to give you special attention to our forum at Chemist Corner, another free resource, but this is a place where any questions you want answered about cosmetic science you can find them here. We have a number of formulators from around the world actually, who participate in discussions here. And so, this is a good free resource for anybody who has questions from anywhere about cosmetic science in the world. And then finally, there’s the practical cosmetic formulator which is online training, and you can get that through there, so. All right, that is my commercial introduction, let me get into the bulk of the presentation today.
Today, we’re going to be talking about Stability Testing, and I’m really going to cover it in three sections. First, we’ll define stability testing, what it is, and why you would ever want to do that. Then we’ll talk about when you’re gonna test your formulas, and why you’re gonna test them. And then finally, I’ll get right into some specifics about the basics of conducting a stability test.
The objectives of this presentation, so hopefully, after listening to this webinar, going through this, you’re gonna first know the basic philosophy of stability testing, you’re also going to be aware of the relevant regulations and the rules that you have to follow. You’re also going to know why and when you’re going to conduct a stability test. It’s not always obvious whether you should or not. And then finally, probably most important, you’re gonna know how do you could conduct those stability tests. So we’ll get into each of these along the way, hopefully, you’ll come out of this knowing these things. I also want to mention that I’m a U.S. based formulator, cosmetic science, and so, my focus is really on what we do here in the U.S., and things around the world might be a little different. I know in the EU they have some different kinds of stability guidelines, in Asia they also do. And I also realize that we have a worldwide audience here. So I can provide links to some of the relevant EU and Asian sources. But I have to say that most of the things that you’re gonna learn in here are applicable anywhere around the world. And as a Formulator this certainly is practical information that would be applicable to anybody wherever they’re formulating. Now, whether the specific paperwork that you got to follow or keep track of, that might be different in other places around the world, but the specific testing really applies anywhere.
