Every product introduced has a specific life span. This life span is divided into different phases. Introduction stage of product life cycle. Growthstage of product life cycle.

Product life cycle of add gel pens

In an organic lab, you mix chemicals together and hope something happens. Ideally, you get a chemical reaction you expect. As a formulating chemistyou mix chemicals together and hope nothing happens.

Unfortunately, they often do react or otherwise change so you need to test your formulas to see how long they will last. This is called Stability Testing and is something a cosmetic scientist spend much of her time doing.

What is stability testing? Stability testing is simply an experiment in which you create a batch of your formula and put samples of it at different environmental conditions for a set period of time.

These conditions vary in temperature and light levels and are meant to simulate what will happen to the product during its life cycle. At select intervals you evaluate your samples for various physical, chemical and performance characteristics to see how they have changed.

This means you can have confident that when the formula is shipped to stores and ultimately customers, it will still be as good as when it was first manufactured. The underlying assumption in stability testing is that increasing storage temperature speeds up any aging reactions that will occur. A handy rule of thumb is that a sample stored at 45C for 8 weeks is equivalent to one that is stored at room temperature for one year.

A sample stored at 45C for 8 weeks is equivalent to one stored at room temperature for a year When do you perform stability testing? But there are times when you need to do stability testing. Here is a short list of some of the most important times to conduct a stability test. New manufacturing procedure — Manufacturing is always trying to find faster ways to make formulas.

This often means they change some order of addition or shorten mixing time. Whenever changes like these happen, it could affect your formula. Run a stability test to see if the change is acceptable. New packaging — Cosmetic products change their look almost yearly so packaging is constantly being modified.

Stability testing helps ensure that it is. How do you stability test a cosmetic? There are no set rules on how you must conduct a stability test for cosmetic products. See the FDA website for more information.

Here is a basic format you can follow for conducting a cosmetic formula stability test. Step 1 — Make your batch. Step 2 — Fill your samples. When appropriate, fill glass jars with the product along with the finished package.

In stability testing, you want to do both glass and packaging if possible. The number of samples depends on how much testing your doing but at minimum you should have 2 samples for each storage condition.

Step 3 — Take initial readings. For aerosol products you will test spray patterns. Step 4 — Put samples at different conditions. Stability testing requires different temperature and light conditions.

Different lighting conditions involve a fluorescent light box and a natural light box to simulate sunlight. Step 5 — Evaluate the product.

Samples should be evaluated at the following intervals. Only the RT, 37C and 4C samples will be evaluated after one year. The highest temperature samples and the light exposed samples only need to be evaluated for the first three test intervals.

The evaluation tests should be the same ones you conducted when taking your initial readings. Step 6 — Determine stability.

After 8 weeks you can confidently decide whether your formula is stable or not. Nearly all products will exhibit some change so it will be up to you and your boss to decide whether the product passed or not.
