DICHLOROMETHANE
Commonly Found In
Overview
Dichloromethane (methylene chloride) is a volatile chlorinated solvent banned in EU cosmetics (Annex II/1389) and classified by IARC as Group 2A (probable human carcinogen). It has no valid cosmetic function and is listed as a prohibited substance in EU/UK regulatory databases. Historically used as an industrial solvent in paint strippers and extraction processes, its cosmetic relevance is as a banned ingredient that must not be present in formulations. Skin and inhalation exposure can cause CNS depression and has been linked to hepatotoxicity.
Also known as: Dichloromethane, Methylene Chloride, DCM, Methylene Dichloride
Key Benefits
No skin benefits. Dichloromethane is a prohibited cosmetic solvent with no intended cosmetic benefit to skin.

π Why Regulations Differ
The EU banned dichloromethane in cosmetics (Annex II/1389) due to its IARC Group 2A carcinogen classification and hepatotoxicity concerns. The US has banned it in paint strippers (consumer use) but not specifically from cosmetics; it has no practical cosmetic function. Japan has no specific cosmetic ban.
Recent Regulatory Changes

Strictness Ranking
πΏ Natural Sources
Produced naturally in small amounts by oceanic sources, macroalgae, wetlands, and volcanic emissions. However, the vast majority in the environment is of industrial origin.
π How It's Made
Produced industrially by chlorination of methane or methyl chloride. Methane reacts with chlorine gas at 400-500Β°C to produce a mixture of chloromethanes, from which dichloromethane is separated by distillation.
π Uses in Cosmetics
Used in cosmetic products primarily for perfuming, solvent.
π¬ Other Applications
Used as a solvent in paint strippers, pharmaceutical manufacturing, coffee decaffeination, metal cleaning, and as a blowing agent in polyurethane foam production.
π‘ Fun Facts
- β’ Dichloromethane was the solvent used in most commercial paint strippers until it was banned or restricted in many countries due to health risks
- β’ It's used to decaffeinate coffee β the beans are soaked in it to dissolve and remove caffeine, then the solvent is removed
- β’ Despite being banned in EU cosmetics, it's still widely used in pharmaceutical manufacturing and food processing globally
