Organic pigments are sensitive to light, heat, and air. It is important to store them properly to prolong their lifespan. When storing organic pigments, it is important to keep them in a cool, dark place. Exposure to light can cause the pigments to degrade, so it is best to store them in a place where they will not be exposed to direct sunlight. Additionally, organic pigments should be stored in airtight containers to prevent exposure to air, which can also cause degradation. It is also important to store organic pigments away from heat sources, as high temperatures can accelerate the degradation process. By following these storage guidelines, you can help prolong the lifespan of your organic pigments and ensure that they remain vibrant and usable for as long as possible.
