Uses in Cosmetics: Boric Acid has been used in cosmetics for its versatile properties, including its function as a pH adjuster and preservative. It helps stabilize the pH of cosmetic formulations, ensuring they remain within the desired range. Additionally, it has been used to prevent the growth of microorganisms in cosmetic products, thereby extending their shelf life.

Skin Sensitivities and Allergies: Boric Acid can potentially pose risks to sensitive skin consumers. It has been known to cause skin irritation and can trigger allergic reactions in some individuals. Allergic reactions may manifest as redness, itching, or discomfort, particularly in those with hypersensitive skin. Therefore, individuals with sensitive skin should exercise caution when using products containing boric acid.

Other Risks Associated with Use: Apart from skin sensitivities, there are concerns about the safety of boric acid in cosmetics. It's important to note that boric acid should not be ingested, as it can be toxic when consumed in large quantities. Additionally, exposure to high levels of boric acid can have adverse effects on reproductive health and may harm the developing fetus.

California Ban: Boric Acid is one of the ingredients banned in cosmetics by the state of California, as per Assembly Bill No. 496, effective from January 1, 2027. This legislative action reflects growing concerns about the safety of boric acid in cosmetic products. The ban aligns California with more stringent ingredient safety regulations, aimed at protecting consumer health and safety.

For consumers with sensitive skin, it is advisable to check product labels carefully and choose cosmetics that do not contain boric acid, especially if they are located in regions with such bans in place. This ensures a reduced risk of skin irritation and potential exposure to its associated health risks.
