Abstract
Linear, polymeric biguanides or salts thereof wherein the polymeric chain is terminated at the cyanoguanidine end group by a C.sub.2 -C.sub.90 primary or secondary amine which is optionally substituted with a functionality such as fluoride, chloride, bromide, iodide, nitro, hydroxyl, ether, sulfide, disulfide, sulfoxide or sulfone. The polymeric biguanides have a high level of biocidal activity accompanied by a low level of toxicity to host organisms and are therefore useful in bactericidal, algicidal and fungicidal compositions, especially in ophthalmic compositions.
