Ammonium perfluorononanoate

Ammonium Perfluorononanoate (CAS no. 4149-60-4) 

Ammonium perfluorononanoate (CAS no. 4149-60-4) is a fluorinated compound. This substance belongs to the class of per- and polyfluoroalkyl substances (PFAS), which are known for their water- and grease-repellent properties. They are made up of carbon chains to which fluorine atoms are strongly bonded.

Ammonium perfluorononanoate, like other PFAS, has been used for its ability to repel water and oil, making it useful in a range of products including water-repellent fabrics, non-stick pans, and in certain cases, cosmetics and personal care products. In cosmetics, it could be used to impart water-resistance to products like mascara or eyeliner.

There is limited specific information available on the skin sensitivities and allergies caused by ammonium perfluorononanoate. However, PFAS in general have been associated with skin irritation and other adverse health effects. Individuals with sensitive skin may experience irritation or allergic reactions when exposed to products containing this ingredient.

PFAS, including ammonium perfluorononanoate, have been associated with a range of health concerns including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression, and cancer. Their environmental persistence and potential to bioaccumulate also pose significant environmental risks.

The regulation surrounding the use of ammonium perfluorononanoate in cosmetics and household products may vary by jurisdiction. In California, according to Assembly Bill No. 496 (Chapter 441), the use of ammonium perfluorononanoate in cosmetic products will be prohibited from January 1, 2027. This ban reflects the growing concern surrounding the health and environmental risks associated with PFAS.

Given the significant health and environmental concerns surrounding PFAS, including ammonium perfluorononanoate, its use in cosmetics and household products is increasingly being scrutinized and restricted. Consumers, particularly those with sensitive skin, are advised to exercise caution and avoid products containing this and other PFAS compounds.
