Ensuring the stability and longevity of your cosmetic products is essential for compliance and consumer confidence. Our stability testing services evaluate how your product performs under different storage conditions, helping you bring safe and reliable products to market.
Why Stability Testing is Important
To legally sell cosmetic products—especially in the UK and EU—you must confirm their stability. According to Cosmetic Regulation (EC) No. 1223/2009, products must demonstrate at least 30 months of stability.
Our accelerated stability testing simulates this by exposing products to higher temperatures over 12 weeks, replicating 30 months of real-time storage at 20°C.
What We Test
We conduct stability testing for a wide range of products, including:
✔ Personal Care (skincare, haircare, body care)
✔ Household Care (cleaning solutions, detergents)
✔ Fragrances & Candles

…and more!
