Sodium nonadecafluorodecanoate (CAS no. 3830-45-3) 

Definition
Sodium nonadecafluorodecanoate is a chemical compound with the CAS number 3830-45-3. It belongs to the class of per- and polyfluoroalkyl substances (PFAS), which are a group of man-made chemicals that have been used in various industries around the world since the 1940s.

Usage in Cosmetics and Household Products
The usage of Sodium nonadecafluorodecanoate in cosmetics and household products is not as common as some other chemicals. However, PFAS, the class of chemicals it belongs to, are known for their water- and grease-repellent properties and can be found in a range of consumer products including non-stick cookware, water-repellent clothing, stain-resistant fabrics and carpets, some cleaning products, and some firefighting foams. The exact role of Sodium nonadecafluorodecanoate in cosmetics or household products would require more specific industry knowledge, but it could potentially be used for its water- or grease-repelling properties.

Other Names/Synonyms
There may be other chemical or trade names for Sodium nonadecafluorodecanoate but they are not well publicized. Its unique identifier is its CAS number 3830-45-3.

Skin Sensitivities and Allergies
There's limited information available on the specific skin sensitivities or allergies related to Sodium nonadecafluorodecanoate. However, other PFAS compounds have been associated with skin irritation in some individuals. It's always advisable for individuals, especially those with sensitive skin, to exercise caution when using products containing unfamiliar ingredients.

Other Risks
PFAS, in general, have been associated with a variety of health issues when humans are exposed to them at high levels or over long periods. These issues include liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression, and cancer.

Regulatory Ban
In the text of California Assembly Bill No. 496 (Chapter 441), Sodium nonadecafluorodecanoate is listed as one of the banned ingredients in cosmetic products effective January 1, 2027. The prohibition extends to the manufacturing, selling, delivering, holding, or offering for sale in commerce any cosmetic product that intentionally contains Sodium nonadecafluorodecanoate among other specified ingredients due to the associated risks of PFAS chemicals.

Conclusion
Given the risks associated with PFAS compounds, Sodium nonadecafluorodecanoate has been subjected to regulatory bans in places like California. While there's limited specific information on Sodium nonadecafluorodecanoate, its association with PFAS compounds suggests a need for caution, especially among consumers with sensitive skin or those looking to minimize their exposure to potentially harmful chemicals.
