Acid Violet 43 (Uncertified Ext. D&C Violet No. 2)
What is Acid Violet 43 (Uncertified Ext. D&C Violet No. 2)?
Acid Violet 43, also called Uncertified Ext. D&C Violet No. 2 or CI 60730, is a synthetic colorant from the anthraquinone family. It arises from chemical processes sulfonating anthraquinone structures for solubility and vibrant hue. Primarily featured in cosmetics for external application like nail polishes, bath products, and some eye area items, it functions by dispersing evenly to deliver a stable violet shade. This dye binds to substrates or remains suspended, resisting fading from light or friction for uniform appearance during use. The uncertified status means it skips FDA batch testing but must adhere to purity specs set by regulators for cosmetic inclusion, distinguishing it from certified counterparts.
