A novel series of cleavable alkyltrimethylammonium surfactants with different hydrocarbon chainlengths (C8-16) were synthesized. A carbonate break site inserted between the polar head and thehydrocarbon chain makes these compounds hydrolyzable. The reagents used are renewable,(bio)degradable or reusable. The hydrolysis of these cleavable surfactants will lead to the generationof fatty alcohols and choline, which is an essential biological nutrient. The surface activities inaqueous solution of the synthesized carbonates fulfill the requirement of being good surfactants. Inaddition, the cleavable compounds containing n-decyl and n-dodecyl chains showed similar or higherantimicrobial activities when compared to a non-cleavable analog.
