Trichloroacetic Acid (TCA)

Uses in Cosmetics: TCA is primarily used in cosmetics as a chemical peel agent. It is employed in various skincare products, including chemical peels and exfoliating treatments. Its exfoliating properties help rejuvenate the skin, reduce the appearance of fine lines, and promote a more even skin tone.

Skin Sensitivities and Allergies: TCA is a potent acid and can cause skin sensitivities, especially in higher concentrations or when not used correctly. Individuals with sensitive skin are more prone to adverse reactions, which can include redness, burning, and peeling of the skin. It's crucial to follow product instructions and consult with a dermatologist or skincare professional before using products containing TCA, especially for individuals with sensitive skin.

Other Risks: Apart from skin sensitivities, TCA may pose risks if not used as directed. It's essential to be cautious when using TCA-containing products and follow the recommended application guidelines to avoid over-exfoliation or excessive skin irritation.

California Ban (Assembly Bill No. 496): As of January 1, 2027, California has implemented Assembly Bill No. 496, which prohibits the manufacture, sale, delivery, holding, or offering for sale in commerce of cosmetic products containing Trichloroacetic Acid (CAS no. 76-03-9), along with several other specified ingredients. This legislative action reflects the state's commitment to enhancing the safety of cosmetic products.

The ban is in place to protect consumers, especially those with sensitive skin, from potential adverse reactions associated with the use of Trichloroacetic Acid. Cosmetic companies must comply with this regulation by removing products containing this ingredient from the market to ensure consumer safety and adhere to the evolving regulatory landscape.
