A novel series of cleavable alkyltrimethylammonium surfactants with different hydrocarbonchain lengths (C8-16) were synthesized. A carbonate break site inserted between the polar headand the hydrocarbon chain makes these compounds hydrolyzable. The reagents used arerenewable, (bio)degradable or reusable. The hydrolysis of these cleavable surfactants will lead tothe generation of fatty alcohols and choline, which is an essential biological nutrient. The surfaceactivities in aqueous solution of the synthesized carbonates fulfill the requirement of being goodsurfactants. In addition, the cleavable compounds containing n-decyl and n-dodecyl chainsshowed similar or higher antimicrobial activities when compared to a non-cleavable analog
