Abstract
This patent discloses the use of poly-substituted isothiouronium salts (T1 where R1, R2, R3, R4=hydrogen, alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, heteroaryl, etc. and X−=Cl−, Br−, NO3−, CH3CO2−, or any other common anion), poly-substituted guanidinium salts (G1 where R1, R2, R3, R5, R6=hydrogen, alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, heteroaryl, etc. and X−=Cl−, Br, NO3−, CH3CO2−, or any other common anion), or mixtures of two or more of the above compounds, as the biocidal component of microbiocidal or anti-fouling formulations.
Claims9
A composition comprising a compound selected from the group consisting of compounds having a first formula
- 3
- where R4 and at least one of the other R1, R2 or R3 groups are selected independently from the group consisting of alkyl, cycloalkyl, alkenyl, cycloalkenyl, and heteroaryl other than phthalocyanine, the remaining R1, R2 or R3 groups are independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, alkenyl, cycloalkenyl, and heteroaryl, and X− is an anion;
- compounds having a second formula
- 4
- where R4 and at least one of the other R1, R2 or R3 groups are independently selected from the group consisting of alkyl, cycloalkyl, alkenyl, cycloalkenyl, and heteroaryl other than phthalocyanine, and the remaining R1, R2 or R3 groups are independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, alkenyl, cycloalkenyl, and heteroaryl;

- compounds having a fourth formula
- 6
- where R1, R2, R3, R5, and R6 are selected such that at least two of the R1, R2, R3, R5 or R6 groups are selected from the group consisting of alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, and heteroaryl and the remaining R1, R2, R3, R5 or R6 groups are independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, and heteroaryl;
- and
