Description:

Bronopol is a formaldehyde-releasing preservative used in personal care products, cleaning products, and topical medications. It preserves products by releasing low levels of formaldehyde over time, a chemical known to be a carcinogen and endocrine disruptor. It is also used in some industrial processes.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Endocrine Disruption

May alter hormone function and contribute to chronic diseases and disorders.

Genotoxicity

May cause mutations or damage DNA in cells.

Neurotoxicity

May impact brain function or development.

Organ System Toxicity

May cause organ damage and disease.

Immunotoxicity & Allergens

May impact immune system function or cause allergic reactions.

Respiratory Toxicity & Asthmagens

May damage the lungs or trigger asthma.

Irritant

May cause skin, eye, or respiratory irritation.

Ecotoxicity

May be toxic to ecosystems and wildlife.

Contaminants:

  • formaldehyde

HOW MILLION MARKER SCORES CHEMICALS

Million Marker's Ingredient Hazard Scoring uses multiple chemical databases and a science-backed scoring system to compute hazard scores for thousands of chemicals found in consumer products and listed on ingredient labels.

We identified key chemicals based on a database compiling dozens of authoritative sources, screening tools, and QSAR models.

Hazard scores within 11 different health categories (carcinogens, endocrine disruptors, reproductive toxicants, developmental toxicants, genotoxicity, neurotoxicity, organ system toxicity, immunotoxicity, respiratory toxicity, skin/eye/respiratory irritants, and ecotoxicity).

They are weighted based on several factors, including strength of evidence for adverse impacts in humans, severity, and potential contamination.
