Abstract
Use of a long chain alkyl ester as a temporary microbicide at pH-values from about 6 to about 8.5. The long-chain alkyl ester has the formula ##STR1## where R.sup.I, R.sup.II, and R.sup.III are hydrogen or lower alkyl groups and R.sup.IV is an long chain alkyl group having 10-18 carbon atoms, R.sup.V is hydrogen or a group having the formula R.sup.VI N.sup.+ H.sub.3 where R.sup.VI is an alkylene group having 3-4 carbon atoms, A is a monovalent counter ion and n is the number of cationic groups in the ester compound. The ester exhibits a temporary microbicidal effect due to a hydrolytic reaction. As a consequence the toxic effect on human and animals cells and tissues will be low.
Claims14
A process of disinfecting at least one of food, human beings, animals and products to be brought in contact with one of food, human beings, and animals to combat microorganisms, comprising:
- exposing the at least one of food, human beings, animals and products to a freshly prepared composition having a pH-value ranging from about 6 to about 8.5 and being comprised of an aqueous medium and a long-chain alkyl ester compound having the formula:
- ##STR8## where R.sup.I, R.sup.II, AND R.sup.III are hydrogen or lower alkyl groups, R.sup.IV is a long-chain alkyl group having 10-18 carbon atoms, R.sup.V is hydrogen or a group having the formula R.sup.VI N.sup.+ H.sub.3, where R.sup.VI is an alkylene group having 3-4 carbon atoms, A is a monovalent counter ion and n is a number of cationic groups in the ester compound.
A process of disinfecting at least one of food, human beings, animals and products to be brought in contact with one of food, human beings and animals to combat microorganisms, comprising:
- exposing the microorganisms to inactivate the microorganisms in an initial phase to a freshly prepared composition having a pH-value ranging from about 6 to about 8.5 and being comprised of an aqueous medium and a long-chain alkyl ester compound having the formula:
- ##STR12## where R.sup.I, R.sup.II, AND R.sup.III are hydrogen or lower alkyl groups, R.sup.IV is a long-chain alkyl group having 10-18 carbon atoms, R.sup.V is hydrogen or a group having the formula R.sup.VI N.sup.+ H.sub.3, where R.sup.VI is an alkylene group having 3-4 carbon atoms, A is a monovalent counter ion and n is a number of cationic groups in the ester compound, and
- detoxicating the long-chain alkyl ester compound of the composition due to hydrolytic reaction thereof which takes place concurently with and subsequently to the initial phase and which reduces the ester compound content of the composition to innocuous levels.
