Category

Biocides/Disinfectants

Description

Halohydantoins: Usually off-white solids; [Reference #1] White or yellowish-white solid with an odor of strong halogens or bromine; [Redox Chemicals MSDS]

Sources/Uses

Halohydantoins: Used as disinfectants in swimming pools, hot tubs, toilet bowls, and industrial systems (cooling water, pulp and paper, wastewater, and sewage); Also used as slimicide for paper/paperboard for food contact; [Reference #1]

Comments

Halohydantoins: The persistent metabolites, 5,5-Dimethylhydantoin (DMH) and 5-Ethyl-5-methylhydantoin (EMH), are used for developing toxicity data for this group of compounds; Quickly decomposed by water forming hypochlorous or hypobromous acid (the true biocidal agents) and DMH or EMH; DMH/EMH: Sub-chronic, developmental, reproductive, and chronic toxicity animal studies have shown non-specific toxicity at high doses (no evidence of carcinogenicity, reproductive or developmental toxicity, and limited evidence of mutagenicity); [Reference #1] An oxidizer that may cause fire on contact with combustible materials; Causes burns; May cause skin sensitization; Inhalation causes irritation to nose and throat; May cause liver and kidney injury; Harmful by ingestion; [Redox Chemicals MSDS] See "1,3-Dichloro-5,5-dimethylhydantoin."
