ACRYLONITRILE
Overview
Acrylonitrile is a flammable, toxic synthetic organic compound banned in EU cosmetics (Annex II/682, CMR1B) and classified by IARC as Group 2B (possible human carcinogen). It has no cosmetic function and is listed in regulatory databases as a prohibited substance. Its primary industrial importance is in the manufacture of acrylic fibers, ABS plastics, and nitrile rubber. It has no legitimate use in personal care formulations.
Also known as: Acrylonitrile, Vinyl Cyanide, Propenenitrile, AN
Key Benefits
No skin benefits. Acrylonitrile is a prohibited cosmetic substance with no intended cosmetic function.

π Why Regulations Differ
The EU banned acrylonitrile in cosmetics (Annex II/682) as a CMR Category 1B carcinogen. IARC classifies it as Group 2B (possibly carcinogenic to humans). The US and Japan do not specifically list it as a prohibited cosmetic ingredient, but it has no functional role in personal care products.

Strictness Ranking
πΏ Natural Sources
Not found in nature. A fully synthetic organic compound. However, small amounts can be released from certain plastics during combustion.
π How It's Made
Produced by the SOHIO process (developed in 1957): propylene, ammonia, and oxygen react over a catalyst at about 450Β°C. About 6 million tonnes are produced annually worldwide.
π Uses in Cosmetics
Used in cosmetic products primarily for not reported.
π¬ Other Applications
Used to make acrylic fibers (clothing), ABS plastics (electronics, automotive), nitrile rubber (chemical-resistant gloves), and carbon fiber precursors (aerospace).
π‘ Fun Facts
- β’ Acrylonitrile is the building block of acrylic fibers β the material in most synthetic sweaters, socks, and 'fake fur'
- β’ ABS plastic (acrylonitrile-butadiene-styrene) is made partly from acrylonitrile β it's what LEGO bricks are made of
- β’ Despite being classified as a probable carcinogen, it's one of the world's most important industrial chemicals due to the vast range of plastics it helps create

Frequently Asked Questions
Why is ACRYLONITRILE banned in the EU but allowed in the US?
The EU follows a precautionary principle, banning ACRYLONITRILE under II/682 - CMR1B due to potential safety concerns. The US FDA has not found sufficient evidence to prohibit its use, allowing it under different safety assessment standards. This reflects differing regulatory philosophies between the two regions.
Why is ACRYLONITRILE banned in the EU but allowed in Japan?
The EU prohibits ACRYLONITRILE (II/682 - CMR1B) based on their strict safety criteria. Japan's Ministry of Health, Labour and Welfare (MHLW) has evaluated the ingredient and permits its use, potentially with different safety data or usage conditions.
What is ACRYLONITRILE used for in cosmetics?
ACRYLONITRILE is primarily used for not reported in cosmetic products. The ingredient is commonly found in various cosmetic and personal care products.
Which countries regulate ACRYLONITRILE?
ACRYLONITRILE is banned in EU, UK. The ingredient is freely allowed in JP, US.
Are there alternatives to ACRYLONITRILE?
Due to regulatory restrictions on ACRYLONITRILE, cosmetic manufacturers often use alternative ingredients with similar functions. For not reported, alternatives may include other approved ingredients in the same category. Consult product labels for specific formulations, and look for products compliant with your region's regulations.
