Abstract

The invention relates to a disinfecting agent, more specifically, to a Gemini-tamed iodine composite bactericide, wherein the agent is recombined from Gemini and I2, the effective iodine content is 6-10 wt%, the constitutional formula is disclosed in the specification. The Gemini-tamed iodine bactericidal agent is an organic-inorganic compound system with greatly improved stability and lowered excitation.

Description

technical field [0001] The invention relates to a disinfectant and bactericide, in particular to a compound bactericide of didodecyl bisquaternary ammonium salt iodophor. Background technique [0002] Quaternary ammonium salt is an important variety of cationic surfactants. Because of its strong adsorption capacity for negatively charged substances, it has antistatic, soft and bactericidal effects. Since DomagkG discovered that the long-chain alkyl quaternary ammonium salt has strong bactericidal properties more than half a century ago, the synthesis of cationic active disinfectants has been one of the more active fields in the research of disinfectants. At present, foreign cationic active disinfectants have been developed to the fifth generation, that is, didodecyl diquaternary ammonium salt (Gemini). Didodecyl diquaternary ammonium salt has a unique molecular structure, and its molecule is usually composed of two (or three) hydrophobic chains, two hydrophilic groups and a...
