Acrylonitrile and pregnancy

Not Recommended

Acrylonitrile is a highly toxic industrial chemical that should never appear as an ingredient in cosmetic products. It's used in manufacturing plastics and synthetic fibers, not in finished consumer products. Its presence in a cosmetic indicates serious contamination or manufacturing error. According to the EPA and ATSDR (Agency for Toxic Substances and Disease Registry), acrylonitrile is a known developmental toxicant. Animal studies show it can cause fetal malformations, reduced birth weight, and developmental delays. It's readily absorbed through skin and by inhalation, reaching the bloodstream and potentially crossing the placental barrier. The International Agency for Research on Cancer (IARC) classifies it as a probable human carcinogen. The EU explicitly prohibits acrylonitrile in cosmetic products under Annex II of the Cosmetics Regulation. ACOG and toxicology experts strongly advise avoiding all exposure during pregnancy. If you encounter a product listing this ingredient, do not use it and report it to regulatory authorities (FDA in the US, relevant agency in your country).

BreastfeedingAVOID

Acrylonitrile and breastfeeding

Not Recommended

Acrylonitrile should never be present in cosmetic products. It's a volatile industrial toxin used in polymer manufacturing. If absorbed, it would readily enter breast milk due to its chemical properties. According to toxicological data, acrylonitrile and its metabolites can pass into breast milk and pose serious health risks to breastfed infants, including potential carcinogenic and neurotoxic effects. The compound is metabolized to toxic substances including cyanide. Any product containing this ingredient should be avoided entirely and reported to health authorities. The presence of acrylonitrile in a cosmetic product represents a serious safety violation.

PostpartumAVOID

Acrylonitrile and postpartum

Not Recommended

Acrylonitrile is a prohibited industrial chemical that should never appear in cosmetic products. It's classified as a probable human carcinogen and is toxic through skin contact, inhalation, and ingestion. Do not use any product listing this ingredient. Report such products to the FDA or your country's regulatory authority immediately, as this represents a serious safety hazard.

Trying to ConceiveAVOID

Acrylonitrile and trying to conceive

Not Recommended

Acrylonitrile is a prohibited industrial chemical with known developmental toxicity. It should never appear in cosmetic products and must be avoided completely when trying to conceive. The presence of this ingredient in a cosmetic product indicates serious contamination or manufacturing error. Report any such product to the FDA or relevant regulatory authority and discontinue use immediately.

PCOSAVOID

Acrylonitrile and PCOS

Not Recommended

Acrylonitrile is a toxic industrial chemical that is prohibited in cosmetics. It should never be used by anyone, regardless of health conditions. If found in a product, this represents a serious safety violation. The chemical is a probable carcinogen and highly toxic through multiple routes of exposure. Do not use any product containing this ingredient. Report it immediately to regulatory authorities.

General UseAVOID

Acrylonitrile and general use

Not Recommended

Acrylonitrile is a volatile, toxic industrial chemical used in manufacturing plastics, synthetic rubber, and acrylic fibers. It is NOT approved for use as a cosmetic ingredient and should never appear in consumer skincare or beauty products. This chemical is classified as a probable human carcinogen (IARC Group 2B) and is highly toxic. According to the EPA and OSHA, exposure causes severe irritation to skin, eyes, and respiratory system, as well as central nervous system effects. Long-term exposure is linked to increased cancer risk, liver and kidney damage, and neurological problems. Even brief skin contact can cause burns and systemic toxicity. The EU explicitly bans acrylonitrile from cosmetic products (Annex II, EU Cosmetics Regulation). If you encounter a product listing this as an ingredient, do not use it. This indicates either dangerous contamination or a counterfeit/illegal product. Report it immediately to the FDA (in the US) or your country's cosmetic safety authority. Legitimate cosmetic products will never contain this ingredient.
