Low Health Concerns
Current research suggests ingredient may be safe for use.
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.
