Sources of exposure:

Industrial uses

Historical dry-cleaning fluids, household cleaning products, fire extinguishers, chemical manufacturing, and contaminated air or groundwater

Description:

Carbon tetrachloride is a volatile chlorinated solvent historically used in cleaning fluids, fire extinguishers, and industrial processes. Most consumer uses have been discontinued because of its toxicity and environmental effects, but it remains relevant in certain industrial applications. Exposure may occur through contaminated air, water, or occupational settings.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Reproductive Toxicity

May alter hormone function and harm reproduction.

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.

Ecotoxicity

May be toxic to ecosystems and wildlife.

Banned/restricted lists:

  • California Proposition 65 - OEHHA - cancer
  • EU Cosmetics Regulation Annex II - Prohibited
  • Health Canada Cosmetic Ingredient Hotlist - Prohibited

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.
