Example: Dettol(It is a mixture of chloroxylenol &1,tepineol),savlon,tincture of iodine(2-3% solution of iodine in alcohol &water),antiseptic used in bathing soap(bathional) Disinfectants-are chemical substances used to kill the micro organism Example:Phenol,DDT, Phenol in lower concentration use as antiseptic but in higher concentration used as disinfectant. Antihistamines-The drugs which is used to prevent the secretion of histamines & stop the allergy action Example:Bromphenyramine(avil),cetrizine,Benadryl(diphenyl hyramine)

9. Soaps & Detergents- are the sodium salts of higher molecular masses fatty acids & aromatic acids. Types of detergents-cationic detergent –the dtergent in which the large hydrocarbon part is cation Example: cetyltrimethylammoniumbromide. Anionic detergent: the detergent in which the large hydrocarbon part is anionic Example:Sodiumdodecylbenzenesulphonate, sodiumlaurylsulphate.

10. Nonionicdetergent:The dtergent having no cationic and anionic part. Example:Polyethyleneglycol steriate. Difference between soaps &detergent 1.Soaps are biodegradable Detergents are nonbiodegradable. 2.Soap form lather with soft water while detergents form lather with soft &hard water.
