Nonadecafluorodecanoic acid

Nonadecafluorodecanoic acid is a chemical compound with the CAS number 355-76-2. It belongs to the class of perfluorinated compounds (PFCs), which are characterized by the replacement of all hydrogen atoms by fluorine atoms on their carbon backbone. This gives the compound unique properties such as high stability and repellency towards water and oils.

Nonadecafluorodecanoic acid may be used in cosmetics and personal care products for its unique properties like water and oil repellency. This makes it suitable for use in products like water-resistant mascara, foundation, and other makeup products. Additionally, it can be used in household products for similar repellent properties, for instance, in stain repellents for fabrics and carpets.

The potential for skin sensitivities or allergies from Nonadecafluorodecanoic acid is not well documented. However, perfluorinated compounds, in general, have been a topic of concern due to their potential to cause irritation and other adverse reactions.

There has been increasing concern regarding the safety of perfluorinated compounds including Nonadecafluorodecanoic acid. Studies have shown that these compounds can be persistent in the environment and may accumulate in the human body over time, potentially posing risks to human health and the environment.

As per the California Assembly Bill No. 496 (Chapter 441), effective from January 1, 2027, the manufacturing, selling, delivering, holding, or offering for sale of any cosmetic product that intentionally contains Nonadecafluorodecanoic acid among other specified ingredients is prohibited. This prohibition is a part of a larger regulation aimed at ensuring the safety of cosmetic products and protecting the public from potential health hazards associated with certain chemical compounds.

Considering the regulatory restrictions and potential health and environmental concerns surrounding Nonadecafluorodecanoic acid and other perfluorinated compounds, consumers, especially those with sensitive skin, are advised to exercise caution when selecting cosmetic and household products. Checking product labels for this ingredient or its synonyms can be a prudent step towards making safer product choices.
