Safflower red is an active substance extracted from the flowers of the safflower plant (Carthamus tinctorius)[1]. As a natural pigment, safflower red is widely used in cosmetics, food products, and traditional medicine due to its vibrant color and natural origin[2]. Additionally, safflower red is considered a safe coloring agent and has been approved for use in several countries[3].
