1,3-Dibromo-5,5-dimethylhydantoin: Does not have an individual approval but may be used under an appropriate group standard

Evidence of thyroid hypofunction in repeated dose study of rats; [RTECS] Corrosive to skin; Not sensitizing to guinea pigs; 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 can intensify fire; Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; Toxic by ingestion; [Aldrich MSDS] See 1,3-Dichloro-5,5-dimethylhydantoin.

Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626)

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]

Pulp and Paper Processing [Category: Industry]

1,3-Dibromo-5,5-dimethylhydantoin is an organobromide compound derived from the heterocycle called dimethylhydantoin. It is widely used as a disinfectant used for drinking water purification, recreational water treatment, as a bleaching agent in pulp and paper mills, and for treating industrial/commercial water cooling systems. Diatomic bromine does not occur naturally, but bromine salts can be found in crustal rock.
