Distearyl dimethyl ammonium bromide (or dimethyldioctadecylammonium bromide (or DDA), a quaternary ammonium salt, that stimulates immune responses and binds to antigens. DDA enhances the immunogenicity of the soluble antigen. It was shown, that complexes of DDA and antigen were effective in eliciting a delayed hypersensitivity reaction, which was desirable for an antitumor effect. Besides, as a part of liposomal adjuvants, DDA can modulate T-helper 1-immune responses.

Malachite green, an N-methylated diaminotriphenylmethane dye, is used primarily as a therapeutic agent in aquaculture. It controls fungal attacks, protozoan infections and some other diseases caused by helminths on a wide variety of fish and other aquatic organisms. In solution, the dye exists as a mixture of the cation (chromatic malachite green) and its carbinol base, with the ratio depending on the pH of the solution; the dye also can undergo chemical and metabolic reduction to a leuco derivative. Malachite green intercalates with DNA, with a preference for A:T-rich regions, and the leuco derivative bears a structural resemblance to carcinogenic aromatic amines that can form covalent DNA adducts. In mammalian cells, it shows marked cytotoxicity and the ability to induce cell transformation and lipid peroxidation. The toxicity of this dye increases with exposure time, temperature and concentration. It has been reported to cause carcinogenesis, mutagenesis, chromosomal fractures, teratogenecity and respiratory toxicity.

DIDECYLDIMONIUM (as a salt, didecyldimethylammonium chloride (DDAC)) is used in many types of biocidal products including tableware, carpets, humidifiers, and swimming pools. It shows a broad spectrum of activity against both gram-positive and gram-negative bacteria and is also effective on fungi and viruses, including those that are enveloped.

Benzododecinium, a quaternary ammonium compound, is an antiseptic agent and disinfectant. Benzododecinium is used as preservative in different pharmaceutical formulations. Thus, the dispenser of Timoptol-LA, used for the treatment of patients with ocular hypertension, contains benzododecinium bromide as a preservative. It is used as preservative and the corneal permeability enhancer in formulation. Benzododecinium is effective against gram-positive microbes.
