Sodium heptadecafluorononanoate

Sodium Heptadecafluorononanoate (CAS no. 21049-39-8) is a chemical compound characterized by its chain of nine carbon atoms, with a sodium atom at one end and a fluorine atom at the other. It belongs to a family of chemicals known as per- and polyfluoroalkyl substances (PFAS).

Sodium Heptadecafluorononanoate, due to its PFAS characteristics, may have applications in cosmetics and household products for its water- and grease-repellent properties. It could be used in formulations to provide a smooth, non-stick or water-resistant finish, and might be found in products like mascara, foundation, or other makeup and personal care items.

• Sodium 1H,1H,2H,2H-heptadecafluorononanoate

The safety profile of Sodium Heptadecafluorononanoate is not well established, and there might be concerns related to skin irritation or allergies, especially for sensitive skin consumers. Its PFAS characteristics could potentially result in adverse skin reactions upon exposure.

The broader class of PFAS chemicals has been associated with various health issues such as liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression, and cancer. They are also persistent in the environment and can accumulate over time, leading to long-term exposure risks.

The California Assembly Bill No. 496 (Chapter 441) lists Sodium Heptadecafluorononanoate (CAS no. 21049-39-8) among the banned ingredients in cosmetic products effective January 1, 2027. This prohibition is due to the recognized health and environmental risks associated with PFAS chemicals.

Due to the potential health risks and environmental concerns associated with Sodium Heptadecafluorononanoate, its usage in cosmetics and household products is under scrutiny and is banned in California from January 1, 2027. Consumers, particularly those with sensitive skin, are advised to check product labels for this ingredient and exercise caution.
