Product Description:
Eosin Y is widely used in histology as a staining agent, particularly in hematoxylin and eosin (H&E) staining, to highlight cytoplasmic components, collagen, and muscle fibers in tissue samples. It provides a pink or red coloration, aiding in the differentiation of cellular structures under a microscope. In the field of biology, it is employed to stain cells and tissues for microscopic examination, helping to identify abnormalities or specific features. Additionally, Eosin Y is used in the cosmetics industry as a dye in lipsticks, blushes, and other makeup products due to its vibrant red color. It also finds application in the textile industry for dyeing fabrics and in the ink industry for producing red inks. Furthermore, it is utilized in photography as a sensitizer in certain photographic processes. Its versatility makes it a valuable compound across various scientific and industrial fields.
