Stability Testing for Product Safety & Compliance
At Q Laboratories, we provide comprehensive stability testing services tailored to the unique needs of personal care, cosmetics, and OTC products. With dedicated stability resources and over 25 chambers including a walk-in real-time chamber, our laboratory offers the capacity, expertise, and flexibility to support your product development and compliance goals.
Our approach ensures that testing for your studies is performed all on one campus, eliminating the need to ship samples to multiple facilities. This streamlined process reduces complexity, shortens timelines, and provides you with a single trusted partner.
Our Capabilities
Our scientists and stability specialists bring deep experience in pharmaceutical testing, ensuring precision and regulatory alignment throughout your study.
All studies are conducted in accordance with International Council for Harmonisation (ICH) guidelines, supporting global regulatory requirements.
We offer real-time, intermediate, and accelerated stability testing under ICH-recommended conditions.
Tailored testing environments to meet specific product or market needs, including refrigerated, frozen, and low/high humidity conditions.
Including freeze-thaw cycles, photostability, and stress testing to evaluate product robustness.
Scalable capacity for small to large-scale programs, including a full walk-in chamber for bulk studies.
Available ICH Stability Testing Conditions
Additional custom conditions available upon request (e.g., refrigeration at 5°C, freezing at –20°C, low humidity studies, high humidity studies, or freeze-thaw cycles).
