what is photo stability

Answer Posted / g. subvrahmanyam

Photo stability deals with direct human exposure hazards aside, over-exposure to light for certain materials and chemicals can cause disastrous changes in their physical and chemical properties leading to product damage, reduced efficacy, hazardous interactions, or some combination of the three. In certain applications, where use of photosensitive substances is heavy, continuous testing for photo stability, or how resistant a substance is to change from light exposure, is performed to maintain product quality or safety.
