Stability testing
We offer a full suite of product stability testing to ensure your product is robust in a multitude of shelf and storage conditions. Accelerated studies help you to bring your product to market more quickly without compromising on its durability.
Avoiding Shelf Issues Down the Line.
For a product to be sold on the market it is important to determine how stable it is. In Europe for example, it is a legal requirement under Cosmetic Regulation (EC) No. 1223/2009 to demonstrate that a cosmetic product is stable for 30 months. Accelerated Stability testing means that a formulation can be tested at elevated temperatures for 12 weeks, which is equivalent to 30 months real-time at 20°c. ADSL is specialised in testing a wide range of products such as Personal Care, Household Care, Fragrances, Candles, Sun Care, Wet Wipes, Novel Foods and much more.
