The rapid development of nanotechnology has transformed the cosmetics industry, leading to the growing application of nanomaterials into cosmetic products globally. Renowned for unique physical properties, these materials enhance product performance by improving ingredient dispersibility, providing antimicrobial and antioxidant benefits, and increasing the transparency of sunscreen formulations.
However, the use of nanomaterials in cosmetics has also raised safety concerns. While no evidence currently links nanotechnology in cosmetics to health risks, uncertainties remain in many aspects about its long-term effects on human health and the environment. Due to their microscopic size and high permeability, nanoparticles may penetrate the skin, enter the bloodstream, and potentially affect vital organs such as the brain and lungs.
In response to these potential risks, regulatory authorities worldwide have begun implementing measures to ensure the safe use of nanomaterials in cosmetics. This article explores the regulatory landscape for nanomaterials in cosmetic regulations across key global regions.
