Documented Uses

• Cosmetics -> Antimicrobial; Deodorant; Antiplaque; Oral care
• Information on 15 consumer products that contain Domiphen bromide in the following categories is provided:
• 1-Dodecanaminium, N,N-dimethyl-N-(2-phenoxyethyl)-, bromide (1:1): ACTIVE
• Prepared by heating phenoxyethyldimethylamine with dodecyl bromide
• The efficacy and tolerability of domiphen bromide (domifen bromide), administered at a dosage of 0.5 mg every 4-6 hr in a double-blind placebo controlled study in 31 patients affected by acute infectious dental diseases, are described. After 2 days of treatment with the drug, there was a significant decrease in pain and inflammation. The drug elicited a good response, improved prognosis and reduced the number of days of illness.
• Domiphen bromide is a quaternary antiseptic with actions and uses similar to those of cationic surfactants.
