Perfluorooctanoic Acid (PFOA)

Perfluorooctanoic Acid (PFOA), with the CAS number 335-67-1, is a synthetic compound belonging to the group of perfluorinated compounds (PFCs). It is a colorless, odorless solid that has been used in various industrial and consumer applications due to its water and grease repellent properties.

PFOA has been used as a surfactant in the formulation of cosmetics and personal care products, providing a smooth, consistent texture and aiding in the distribution of pigments and other ingredients. In household products, it has been utilized for its stain-resistant and water-repellent properties in items like carpeting, upholstery, and cookware.

While PFOA may not directly cause skin irritations or allergies, its presence in products can lead to systemic absorption, which may pose significant health risks. Consumers with sensitive skin may want to avoid products containing PFOA or related compounds to minimize potential exposure.

PFOA is associated with several health risks, including liver toxicity, disruption of lipid metabolism, immune system disorders, and potential carcinogenicity. Moreover, PFOA is persistent in the environment, leading to long-term exposure and accumulation in living organisms.

In California, legislation effective from January 1, 2025, under Assembly Bill No. 496, bans the use of PFOA in cosmetic products due to its associated health risks. The prohibition extends to the manufacturing, selling, delivering, holding, or offering for sale of cosmetic products containing PFOA among other specified ingredients, aiming to protect public health and the environment from the potential harms of PFOA exposure.

Due to the significant health and environmental risks associated with PFOA, its use in cosmetics and household products is being regulated and phased out in places like California. Consumers, especially those with sensitive skin, are advised to check the ingredient lists of products and avoid those containing PFOA or related compounds.
