Vivid products do not contain irgarol / cybutryne as a biocide. CAS #28159-98-0

Hence the ban on such ingredient should not affect this product line. Vivid may contain a different biocide to mitigate algae growth of it may not have any biocide and thus does not mitigate against algae growth.

Vivid list of ingredients is included in the Safety Data Sheet linked here.

FYI, the colorant choice of a bottom paint does not change the active ingredients, it is no consequence other than visual appearance to persons not aboard the vessel.

Pettit has been advertising Triton Odyssey https://www.pettitpaint.com/triton

Their advertised testing looks very encouraging.

I was waiting for this new product to be available in red, but that color took longer for the EPA to approve. I believe it is now available in all their color range.

So far Pettit only list blue and black in their list of SDS for Triton product of ablative antifouling line.

It could be that they have yet to publish the SDS for any other color but that would be a huge error as to marketing and regulations and would result in loads of paint being returned as rejected deliveries. No published or accompanying SDS, no acceptance of delivery for goods being the norm. Returned goods become a major expense to the manufacturer for which heads will roll.

Triton uses Tralopyril as an active ingredient. Tralopyril is a pyrrole resulting from the N-dealkylation of the ethoxymethyl group of chlorfenapyr. It is the active insecticide of the proinsecticide chlorfenapyr. It has a role as an acaricide, an insecticide and an antifouling biocide. It is an organochlorine acaricide, an organochlorine insecticide, an organofluorine acaricide, an organofluorine insecticide, a member of pyrroles, a nitrile, a member of monochlorobenzenes and an organobromine compound.

Water stability of a new antifouling biocide Tralopyril and its toxicity to freshwater algae,
Annual Congress on Environmental Pollution and Sustainable Energy

July 20-22, 2017 Melbourne, Australia

https://www.longdom.org/proceedings/...api-38033.html

Abstract :
Statement of the Problem: The attachment of the aquatic organisms on unprotected ship hulls significantly increases the fuel consumption. The principal strategy to prevent the biofouling is the application of antifouling system, containing biocides. One of the newly emerged biocides is tralopyril (TLP) showing promise especially towards hard fouling (e.g., barnacles and mussels). Since all antifouling biocides are toxic by nature, the risks of their toxicity to non-target species has to be evaluated, however not much scientific ecotoxicity data is available for TLP. The aim of our study was to investigate the toxicity of TLP on freshwater algae, Pseudokirchneriella subcapitata together with the water stability study of TLP. Methodology: Acute, 72-hours toxicity test was performed on freshwater algae P. subcapitata, following ISO guideline. Six TLP concentrations (1-100 μg/L) were tested and algal density for each concentration was measured after 0, 24, 48 and 72 hours using fluorometry. The stability of TLP in algal media was assessed using HPLC with fluorescence detector. Findings: Chemical analysis showed that TLP rapidly hydrolyzes in water media with a half-life of 1.8 hours for the initial concentration 100 μg TLP/L. Along the TLP degradation, one degradation product (CL) formed, of which concentrations were also quantified. The toxicity to freshwater algae was observed already after 24 hours exposure with a 100% algal growth inhibition at 100 μg TLP/L. Due to the rapid degradation of TLP, the growth inhibition could only be plotted against the nominal concentrations. The following nominal EC50s were obtained: 53, 60 and 73 μg/L for 24, 48 and 72 hours exposure time, respectively. Conclusions: Results indicate high acute toxicity of TLP to freshwater algae, which is with time diminished due to the transformation of TLP to a less-toxic transformation product.

I had an email from Pettit last week that announced the red, green and white colors were now available.

[George DuBose]

Black and blue Triton Odyssey were available since February 2021.

Acute toxicity of tralopyril, capsaicin and triphenylborane pyridine to marine invertebrates

Abstract
A need for environmentally acceptable alternative antifouling (AF) biocides has arisen through restrictions in the use of many common biocides in the European Union through the Biocidal Product Regulation (Regulation EU No. 528/2012). Three such alternatives are triphenylborane pyridine (TPBP), tralopyril and capsaicin. This study aims at extending the available information on the toxicity of these three emerging AF biocides to key marine invertebrates. Here we investigate the toxicity of tralopyril and capsaicin to the early life stages of the mussel Mytilus galloprovincialis and the sea urchin Paracentrotus lividus and also of tralopyril, capsaicin and TPBP to the early life stages of the copepod Tisbe battagliai. The EC50 that causes abnormal development of mussel’s D-veliger larvae and impairs the growth of sea urchin pluteus larvae are respectively 3.1 and 3.0 μg/L for tralopyril and 3,868 and 5,248 μg/L for capsaicin. Regarding the copepod T. battagliai, the LC50 was 0.9 μg/L for tralopyril, 1,252 μg/L for capsaicin and 14 μg/L for TPBP. The results obtained for the three substances are compared to a reference AF biocide, tributyltin (TBT), and their ecological risk evaluated. These compounds pose a lower environmental risk than TBT but still, our results suggest that tralopyril and TPBP may represent a considerable threat to the ecosystems.

I remember when they banned TBT it was still on hardware store shelves as an anti-mold additive.

If I'm wrong, someone will clarify for me, but I think "biocide" (usually listed as the copper amount, e.g., 37%, 40%, 60%) and "anti-slime" (sometimes referred to as bio-booster) are being convoluted. I don't use Trinidad, but Micron CSC, Micron Extra, and Biocop TF all use cuprous oxide for biocide. For anti-slime, Extra uses irgarol, and Biocop uses zinc omidine. CSC doesn't have an anti-slime.


As far as Pettit paint, you may still find paint with irgarol but they're not manufacturing paint with irgarol any longer. Ultima SR 60 and 40 use cuprous oxide (60% and 40% respectively) with irgarol (SR is "slime resistant") as the bio-booster/antislime. Odyssey 60 uses 65% cuprous oxide and no antislime. The tech rep was big on their new product, Triton that uses a triple biocide formula of copper thiocyanate, ECONEA, and zinc omadine. I don't know what it equates to as far as copper load % that is traditionally used, but on Defender it lists copper thiocyanate as 15%, and ECONEA and zinc omadine as 6% respectively. That's a significantly lower copper load, but it may be comparing apples and oranges. I don't know the chemical differences of copper thiocyanate and cuprous oxide. Maybe you don't need as much copper thiocyanate as you do if you use cuprous oxide in order to get the same protection. I think the copper thiocynate is "white copper." They don't separate biocide and antislime as they seem to view it as a combination for Triton Triple. Triton has an 18 month warranty, but I don't know if it has restrictions, i.e., has to be professionally applied, certain weather, etc. The tech did say they've used it in the Bahamas and recently got permission to market it in the US.


If anyone has used Triton, I'd appreciate feedback. I looked on line and some places are out of stock or have limited colors.

Zengirl, I being a Montanan typically carry bear spray when going walk about.

It is not necessary in the dead of winter when we go cross country skiing as the bears are in hibernation and no longer a biohazard to contend with, or at least one hopes such to be the case.

Wind drifted bear spray is very harsh on one's eyes and lungs, can be quite debilitating. If you get a back blast of the fog, the good thing is that one can't continue to see where the bear is or if it still is around, so there is that lessening of the visual awareness fear factor, and the pain in your eyes will override any pain from being mauled by the bear.

Bear spray [a.k.a. bruin seasoning] also works on other animals and ornery people.

Fstbttms, what is your experience with Trinidad HD? I just hauled my boat, 5 years on Petit Trinidad 1875 (Black). Still looked almost perfect. I contacted Petit, and they recommended HD. I’d been leaning toward SR or Pro or even 75. On-the-hard for a couple of weeks, and need to order. Oh, and I’m in Washington state, San Juan Island area.

I don't believe I have any experience with Trinidad HD. If I have cleaned any boats that use it, I am unaware of it.

Just got two gallons of the Trinidad Odyssey, (Blue) after reading these posts I will be wearing my best breathing filter when sanding. I hope it works well. They are sure pretty proud of it. ($$)

Smart. Never mess with sanding any boat thing without a respirator.
