The effect of light on product stability is not negligible as heat. Some retail products cause photo-catalytic reactions such as oxidation and degradation by absorbing sunlight, which causes product failure, which is why some products require opaque packaging. Therefore, studying photostability is essential to provide a reasonable formulation, production process and storage conditions.
As an expert in stability testing, Alfa Chemistry’s multidisciplinary scientists conduct light stability testing in strict accordance with the guidelines of the ICH and other regulatory agencies. We use light sources in confined spaces to perform light stability tests on directly exposed products and packaged products. The output of these sources is similar to outdoor daylight, simulating the exposure of retail merchandise to artificial daylight, and the light stability of the test product helps determine if the product formulation or packaging needs to be replaced before marketing. For more information on light stability studies, please feel free to contact us.
The light sources Alfa Chemistry uses include but not limited to:
Artificial daylight tubes
Xenon lamps
Tungsten-mercury lamps
Natural light
Cool white fluorescent lamp
