Product Status. Antifouling (AF) biocides are the active ingredients in AF paints that prevent the widely used over a number of decades, for example Irgarol 1051 and diuron, once again become the predominant antifouling biocide, but its use in AF paints monly used 'booster' biocides, e.g. diuron and Irgarol 1051), their occurrence Sep 7, 2020 and irgarol, a biocide used in agriculture and antifouling paints. marine environment, with a half-life for irgarol-1051 between 100. Apr 12, 2017 In the past, Irgarol 1051 was the most common co-biocide in use. However, it has not been available since late 2014.

(PDF) Antifouling Paints Biocides (Irgarol 1051 and Diuron) in the Selected Ports of Peninsular Malaysia: Occurrence, Seasonal Variation and Ecological Risk Assessment. Irgarol® 1051 [ N ′- tert -butyl- N-cyclopropyl-6- (methylthio)-1,3,5-triazine-2,4-diamine], 96.0–99.0%, provided by BASF Chemicals, and Econea® biocide [ (4-bromo-2- (4-chlorophenyl)-5- (trifluoromethyl)-1H-pyrrole-3‑carbonitrile)], 98%, provided by Janssen PMP, were the selected antifouling agents to be immobilized (SI Fig. S1). As required by the U.S. Environmental Protection Agency, Irgarol 1051 is prominently listed in the active ingredients, usually under its systematic name, N-Cyclopropyl-N- (2-methyl-2-propanyl)-6- (methylsulfanyl)-1,3,5-triazine-2,4-diamine. It typically represents about 2 percent of the paint by volume. This brings us to Irgarol 1051, an antifouling algaecide that is added to boost the performance of the copper biocide in antifouling paint.

Occurrence and impacts of a new antifouling biocide Irgarol-1051 (2-methylthio-4-tert- butylamino -6-cyclopropylamino -s-triazine) have been studied in coral reef waters around Okinawa Islands, Japan. The average concentration of Irgarol detected at commercial and fisheries Ports was 24.70 ± 9.88 ng/L. 2009-06-01 Abstract. The biocide Irgarol 1051 has been reported to have negative effects on a large number of living components including non-target organisms, but information on its impact on the marine meiofauna and benthic prokaryotes is completely lacking. Irgarol is a highly effective biocide used in antifouling coatings to prevent the growth of periphyton. Environmental concentrations of Irgarol in marine and freshwater have often exceeded the effect concentrations of autotrophic organisms tested in the laboratory and give reason for concern that natural periphyton communities may be endangered. Irgarol-1051 is a major antifouling biocide used worldwide.

Please note: A dangerous goods surcharge may apply - more information can be found on our delivery term sustainability of the use of the antifouling biocides tributyltin (TBT), copper, Irgarol® 1051, Sea-Nine™ 211 and zinc pyrithione, used for the protection of Irgarol-1051 is one among the common antifouling compounds of the group of booster biocides. Irgarol-1051 has been widely used as alternative antifouling chemical after the prohibition of tri-butyl tin (TBT) by International Maritime Organization (IMO) (Gatidou et al., 2007). Emerging booster biocides contamination raises particular attention in the marine ecosystem health. This study provides the baseline data on the occurrence of Irgarol-1051 (2-methylthio-4-tert-butylamino-6-cyclopropylamiono-s-triazine) in the selected coastal water around Malaysia. The chemical compound 2-methythiol-4- tert -butylamino-6-cyclopropylamino- s-triazine (Irgarol-1051) is booster biocide that has been used to prevent biofouling on submerged surfaces such as boats, navigational buoys, underwater equipment and ships in marine environment.
