Uses in Cosmetics: In the past, Malachite Green was used as a colorant in cosmetics, contributing its distinctive green hue to a range of products. These cosmetic items included items such as eyeshadows, nail polishes, and hair dyes. However, it's essential to note that its use in cosmetics has significantly declined due to safety concerns.

Skin Sensitivities and Allergies: Malachite Green has been associated with skin sensitivities and allergies. Individuals with sensitive skin should exercise caution when using products that contain this ingredient, as it may lead to skin irritation, redness, or itching. Allergic reactions can vary from mild to severe, and it's advisable to perform a patch test before using products containing Malachite Green, especially if you have a history of skin sensitivities.

Other Risks: Apart from potential skin sensitivities, Malachite Green has been the subject of concern due to its safety profile. The compound has been scrutinized for its potential health risks, particularly when used in cosmetics. It has raised concerns about its safety in personal care products.

California Ban (Assembly Bill No. 496): As part of an effort to enhance consumer safety, California has taken legislative action through Assembly Bill No. 496. Commencing January 1, 2027, this bill prohibits the manufacture, sale, delivery, holding, or offer for sale in commerce of any cosmetic product that contains Malachite Green (CAS no. 569-64-2) as an intentionally added ingredient.

This legislative move reflects the growing recognition of the potential risks associated with Malachite Green in cosmetics. California, known for its strict safety standards, is aligning itself with more stringent ingredient safety regulations. The ban aims to protect consumers, particularly those with sensitive skin, from potential adverse effects associated with this ingredient.

Exemption for Trace Quantities: It's important to note that if a cosmetic product contains a technically unavoidable trace quantity of Malachite Green stemming from impurities of natural or synthetic ingredients, the manufacturing process, storage, or migration from packaging, that trace quantity shall not cause the cosmetic product to be in violation of this section.

Conclusion: Given the concerns surrounding skin sensitivities, allergies, and the recent ban in California, it is advisable for consumers, especially those with sensitive skin, to be cautious when selecting cosmetic products and to check ingredient labels for the presence of Malachite Green
