CI 73000

Description

CI 73000, also known as Brilliant Blue FCF or Blue 1, is a synthetic colorant widely used in cosmetics and personal care products. This water-soluble dye imparts a vibrant blue hue to various formulations, including skincare products, makeup, and hair care items. Its molecular structure allows for excellent color stability across a wide pH range, making it versatile for different product types.

In skincare formulations, CI 73000 is primarily utilized for its aesthetic properties, helping to create visually appealing products that can enhance consumer experience. It is particularly effective in clear or translucent formulations where its intense blue color can be showcased. The dye has been approved by regulatory bodies such as the FDA and EU Commission for use in cosmetics, with specific concentration limits depending on the application.

While CI 73000 does not offer direct skin benefits, its role in product formulation is crucial for brand identity and consumer preference. It's important to note that some individuals may be sensitive to synthetic dyes, including CI 73000. Formulators should consider potential allergenic properties and adhere to regulatory guidelines when incorporating this colorant into skincare products. Always perform appropriate safety assessments and stability testing when using CI 73000 in new formulations.
