During transportation of cosmetic products, it is not uncommon for them to encounter extreme temperature conditions, such as freezing or overheating. Thus, it is necessary for cosmetic products to be able to withstand a certain degree of temperature changes in transport. Freeze-thaw cycle testing is a part of stability testing that allows...
When testing a cosmetic or personal care product for shelf-life and stability, packaging is a major factor that should be taken into consideration. While the product itself may have a relatively stable shelf-life when tested in glass or another temporary package, the same stability may not be observed in...
Cosmetic and personal care products may be exposed to many different conditions throughout their life cycle. When considering a stability testing regimen, it is necessary to try to replicate the conditions that they are most likely to experience during their transport, storage and use. When we go outside and our bodies are...
Realtime Aesthetic Stability Testing is very similar to the accelerated aesthetic test in that it tests for all the same characteristics, however products tested in realtime are stored at room temperature or the product's recommended storage conditions for the full length of shelf life testing. Accelerated Testing is commonly used to screen...
Cosmetic and personal care products that are intended for storage at room temperature have two options for stability testing, real-time and accelerated testing. Many people are unaware that stability testing can be performed at an accelerated rate. Accelerated shelf-life testing is based on the idea that a product that...
