HYDROQUINONE Chemical compatibility with O-rings, rubbers, & plastics

Hydroquinone is a white, crystalline solid with the chemical formula C₆H₄(OH)₂, widely used in various industrial and cosmetic applications. It serves as a photographic developer, an antioxidant in rubber production, and a key ingredient in skin-lightening products for treating hyperpigmentation. Despite its utility, hydroquinone poses significant health risks. Prolonged exposure can cause skin irritation, respiratory issues, and potential carcinogenic effects. In cosmetic use, it may cause ochronosis, a condition leading to skin darkening. Proper handling, storage, and adherence to safety regulations are essential to minimize health risks and ensure the safe use of hydroquinone in industrial and consumer products.
