ACID YELLOW 73

Description

Acid Yellow 73, also known as Fluorescein sodium or D&C Yellow No. 8, is a synthetic organic compound widely used in the cosmetic and pharmaceutical industries. This water-soluble dye belongs to the xanthene class and is characterized by its bright yellow-green fluorescent properties.

In skincare formulations, Acid Yellow 73 serves primarily as a colorant, imparting a vibrant yellow hue to various products. Its fluorescent nature makes it particularly useful in products designed for visual appeal or those requiring easy identification. The ingredient is FDA-approved for use in drugs and cosmetics, with specific regulations governing its concentration in different applications.

Beyond its cosmetic uses, Acid Yellow 73 has significant medical applications. It's employed in ophthalmology for diagnostic purposes, such as detecting corneal abrasions and assessing tear film dynamics. In dermatology, it can be used in photodynamic therapy for certain skin conditions.

While generally considered safe when used as directed, some individuals may experience sensitivity to this dye. As with any colorant, patch testing is recommended before widespread use in skincare products. Formulators should be aware of regulatory limits and potential interactions with other ingredients when incorporating Acid Yellow 73 into their formulations.
