Description:

Hexabromocyclododecane is a brominated flame retardant formerly used in building materials, textiles, and electronics. It is classified as a Persistent Organic Pollutant (POP) under the Stockholm Convention, and its use has largely been replaced by alternative flame retardants.

Health concerns:

Reproductive Toxicity

May alter hormone function and harm reproduction.

Genotoxicity

May cause mutations or damage DNA in cells.

Ecotoxicity

May be toxic to ecosystems and wildlife.

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.
