| Uses |
Erythrosin B (FD&C Red #3) is a colorant. It is not recommended for use below ph 5.0, being insoluble at ph 3–5 but being stable at ph 7 and 8. It has a solubility in water of 9 g/100 ml at 25°c. It has fair stability to oxidation and poor to fair stability to light, while having good stability in 10% sugar systems. It has exceptional clarity and brilliance, having a bluish pink hue with very good tinctorial strength. It has poor compatibility with food components and is used in candies and confections as well as cherry dyeing. The common name is erythrosine.
