CAS 13473-26-2: Red No. 27

Description: Red No. 27, also known as D&C Red No. 27, is a synthetic dye primarily used in cosmetics, personal care products, and some food applications. It is classified as a water-soluble azo dye, characterized by its vibrant red hue. The chemical structure of Red No. 27 includes azo (-N=N-) linkages, which are common in many synthetic dyes, contributing to their color properties. This dye is known for its stability under various conditions, making it suitable for use in a range of formulations. However, like many synthetic dyes, it is subject to regulatory scrutiny due to potential health concerns, including allergic reactions in sensitive individuals. The dye is approved for use in specific applications by regulatory bodies, but its use in food products may be limited or prohibited in certain regions. Overall, Red No. 27 is valued for its intense color and versatility, but safety assessments are essential to ensure consumer protection.
