Benzoyl peroxide

Over-the-counter acne gels, creams, and washes; workplaces where it’s used as a curing/polymerization agent for plastics, resins, and fiberglass products [1][2].

Skin contact from acne products, accidental eye contact, or breathing dust or mists during manufacturing, mixing, or cleanup at work [1][2].

Can cause skin and eye irritation or allergic contact dermatitis; inhaling dust irritates the nose and throat and may worsen asthma. IARC: not classifiable as to carcinogenicity in humans (Group 3) [1][2].

Workers handling benzoyl peroxide powders/pastes; people with sensitive skin, eczema, or asthma; frequent users of acne products, especially at higher strengths [1][2][3].

For acne, follow the label, start with a small test area, use the lowest effective strength, avoid eyes and broken skin, and wash hands after use [3]. At work, use local exhaust, minimize dust, store away from heat, and wear gloves/eye protection per your safety data sheet [1].
