使用上の注意
殺菌力は菌体への吸着によるものであるが、有機物の存在や汚染により競合吸着が発生し、殺菌力が低下するので注意が必要である。また、石鹸(陰イオン界面活性剤)は沈殿を発生し、殺菌力を低下させる。
説明
Benzalkonium chloride is a quaternary ammonium
mixture of alkyl, dimethyl and benzyl ammonium
chlorides.It is an irritant rather than a sensitizer,
but may cause contact dermatitis in nursing and
medical personnel. An unusual case was reported in a
farm worker who used a detergent containing benzalkonium
chloride to clean the piggery.
化学的特性
Benzalkonium chloride occurs as a white or yellowish-white
amorphous powder, a thick gel, or gelatinous flakes. It is
hygroscopic, soapy to the touch, and has a mild aromatic odor
and very bitter taste.
使用
benzalkonium chloride is a preservative with anti-microbial and deodorant properties. It can also be used as a surfactant. With continuous use, it may cause occasional allergic reactions.
定義
ChEBI: A class of quaternary ammonium chloride salts in which the nitrogen is substituted by a benzyl group, two methyl groups and an even-numbered alkyl chain.
調製方法
Benzalkonium chloride is formed by the reaction of a solution of Nalkyl-
N-methylbenzamine with methyl chloride in an organic
solvent suitable for precipitating the quaternary compound as it is
formed.
危険性
Highly toxic; poison.
応用例（製薬）
Benzalkonium chloride is a quaternary ammonium compound used
in pharmaceutical formulations as an antimicrobial preservative in
applications similar to other cationic surfactants, such as cetrimide.
In ophthalmic preparations, benzalkonium chloride is one of the
most widely used preservatives,at a concentration of
0.01–0.02% w/v. Often it is used in combination with other
preservatives or excipients, particularly 0.1% w/v disodium edetate,
to enhance its antimicrobial activity against strains of Pseudomonas.
In nasal, and otic formulations a concentration of
0.002–0.02% w/v is used, sometimes in combination with
0.002–0.005% w/v thimerosal. Benzalkonium chloride 0.01%
w/v is also employed as a preservative in small-volume parenteral
products. Benzalkonium chloride was also shown to enhance the
topical penetration of lorazepam.
Benzalkonium chloride is additionally used as a preservative in
cosmetics.
农业用途
Biocide, Algaecide, Fungicide: Used as an algaecide to control slime mold, algae,
fish pathogens, and mollusks in ponds, canals and bodies of water. Also widely used in deodorants, detergents,
sanitizers and germicides for applications in food plants,
laundries, and operating rooms. Not listed for use in
EU countries
. Registered for use in the U.S. but not
California.

接触アレルゲン
This quaternary ammonium cationic surfactant is a
mixture of alkyl, dimethyl, and benzyl ammonium
chlorides (-R). It is an irritant rather than a sensitizer,
but may cause allergic contact dermatitis from creams,
detergents/antiseptics, ophthalmic preparations, and in
nursing, veterinary, dental, and medical personnel. Its
presence was observed in plaster of Paris.
臨床応用
Alkylbenzyldimethylammonium chloride (Zephiran) is a mixtureof alkylbenzyldimethylammonium chlorides of the generalformula [C6H5CH2N(CH3)2R] Cl , where R represents amixture of alkyl chains beginning with C8H17 and extendingto higher homologues with C12H25, C14H29, and C16H33. The higher–molecular-weight homologues compose the majorfractions. Although variations in the physical and antimicrobialproperties exist between individual members of the mixture,they are of little importance in the chemistry of the overallproduct. Benzalkonium chloride occurs as a white gel thatis soluble in water, alcohol, and organic solvents. Aqueous solutionsare colorless, slightly alkaline, and very foamy.
Benzalkonium chloride is a detergent, an emulsifier, anda wetting agent. It is used as an antiseptic for skin and mucousmembranes in concentrations of 1:750 to 1:20,000. Forirrigation, 1:20,000 to 1:40,000 concentrations are used. Forstorage of surgical instruments, 1:750 to 1:5,000 concentrationsare used, with 0.5% NaNO3 added as a preservative.
副作用
Clinically, benzalkonium chloride may cause eye irritation and is known to discolour soft contact lenses.
Benzalkonium chloride in eye drops has also been reported to cause punctate keratopathy and/or toxic
ulcerative keratopathy, especially in frequent or prolonged use or in conditions where the cornea is
compromised.
貯蔵
Benzalkonium chloride is hygroscopic and may be affected by light,
air, and metals.
Solutions are stable over a wide pH and temperature range and
may be sterilized by autoclaving without loss of effectiveness.
Solutions may be stored for prolonged periods at room temperature.
Dilute solutions stored in polyvinyl chloride or polyurethane
foam containers may lose antimicrobial activity.
The bulk material should be stored in an airtight container,
protected from light and contact with metals, in a cool, dry place.
不和合性
Incompatible with aluminum, anionic surfactants, citrates, cotton,
fluorescein, hydrogen peroxide, hypromellose,iodides, kaolin,
lanolin, nitrates, nonionic surfactants in high concentration,
permanganates, protein, salicylates, silver salts, soaps, sulfonamides,
tartrates, zinc oxide, zinc sulfate, some rubber mixes, and
some plastic mixes.
Benzalkonium chloride has been shown to be adsorbed to
various filtering membranes, especially those that are hydrophobic
or anionic.
規制状況(Regulatory Status)
Included in the FDA Inactive Ingredients Database (inhalations, IM
injections, nasal, ophthalmic, otic, and topical preparations).
Included in nonparenteral medicines licensed in the UK. It is also
included in the Canadian List of Acceptable Non-medicinal
Ingredients.
