NITROMETHANE.

Avoid CAS 75-52-5 / ANTICORROSIVE

Nitromethane is an organic compound primarily incorporated into cosmetic formulations to act as an anticorrosive agent, safeguarding packaging integrity. It offers no inherent beneficial effects or functional contributions to the skin itself.

Summary

Anticorrosive agent

Science

Mechanism of Action

Within cosmetic systems, Nitromethane's sole mechanism is the prevention of packaging corrosion. It exhibits no observed biological activity or therapeutic effects when applied topically to the skin.

0.3%

The inclusion of Nitromethane in skincare formulations is solely for packaging preservation, providing no dermatological value. Given its classification as a suspected carcinogen and reproductive toxicant, its presence, even at legally restricted concentrations (up to 0.3%), represents a significant safety concern for direct skin application.

Nitromethane is listed under Annex III of the EC Cosmetics Regulation as a restricted substance, permissible only as a rust inhibitor at a maximum authorized concentration of 0.3%. It is categorized as IARC Group 2B (possibly carcinogenic to humans) and is a reportable ingredient under California's Safe Cosmetics Program due to carcinogenicity. Safety Data Sheets indicate potential for cancer and damage to fertility or the unborn child. Regulatory bodies like the FDA express concerns regarding carcinogens and substances with potential reproductive toxicity in cosmetic products.
