What is isocyanuric acid?
Isocyanuric acid, at concentrations of about 25 mg/L (0.19 mM), is used in swimming pools to prevent the destruction of available chlorine by ultraviolet light. In the laboratory, isocyanuric acid is used for the production of cyanic acid. Sodium isocyanurate is not produced commercially in the United States.
What is the difference between cyanuric acid and isocyanuric acid?
Forms of stabiliser Stabiliser is available as cyanuric acid, which does not contain chlorine and lowers the pH when added to swimming pool water. Trichloro-isocyanuric acid (trichlor) contains 90% available chlorine that dissolves slowly and is highly acidic when added to pool water.
What is isocyanuric acid used for?
Cyanuric acid is known as a stabilizer for the chlorine in swimming pools exposed to sunlight. It helps reduce the chlorine loss by protecting the free chlorine in the pool from the sun’s ultraviolet rays, reducing the amount of chlorine needed to maintain proper sanitizer levels.
Is cyanuric acid carcinogen?
There is inadequate evidence for carcinogenicity in humans (IARC 1999). Cyanuric acid has low acute toxicity in mammals, with a rat oral LD50 of 7,700 mg/kg body weight for rats (OECD 1999).
Is cyanuric acid the same as baking soda?
Baking Soda is used for raising the total alkalinity of the pool, which is the key to keeping the ph in balance. It’s not a stabilizer. That’s cyanuric acid.
What do you do when pool cyanuric acid is high?
Yes, the most economical way to lower CYA is to partially drain and dilute the pool with fresh water. Consult a pool professional if you want to drain more than 1/3 of your water, because there are risks with hydrostatic pressure and other concerns.
How harmful is cyanuric acid?
Although cyanuric acid offers a low level of toxicity without any serious health concerns, having high-levels of this chemical in a pool puts people at risk because of the chlorine’s diminished ability to kill bacteria and viruses.
Is it safe to swim if cyanuric acid is high?
Does bleach contain cyanuric acid?
Regular bleach, or sodium hypochlorite – contains no cyanuric acid.
Is cyanuric acid harmful?
Does cyanuric acid affect pH?
All alkaline materials are buffers. Cyanuric acid happens to be the most common buffer found in pool water. In effect, cyanuric acid helps stabilize both chlorine and pH. It binds with chlorine to prevent photolysis and it keeps pH elevated.
Is it safe to swim in a pool with high cyanuric acid?
What are the negative effects of isocyanuric acid?
Isocyanuric acid was found to give primarily negative results in a variety of prokaryotic and mammalian assays for genotoxicity. Isocyanuric acid, however, did induce an increase in chromatid and chromosomal aberrations in human lymphoid cells, and was reported to be incorporated into the nucleic acid of Escherichia coli .
Is it safe to use isocyanuric acid on rabbits?
50values for isocyanuric acid and sodium isocyanurate indicate that the compounds are slightly toxic to practically nontoxic. Application of isocyanuric acid in aqueous solution to rabbit skin caused slight to severe irritation, whereas application of isocyanuric acid in saline solution produced no irritation.
Which is the biodegradable form of isocyanuric acid?
Isocyanuric acid is readily biodegraded into carbon dioxide and ammonia by microorganisms, provided that there is no other source of nitrogen (Zeyer et al., 1980, 1981; cited by Shayela et al.,1988). Isocyanuric acid biodegrades particularly well in either low or zero dissolved-oxygen levels (HSDB, 1996).
What is the formula for triallyl isocyanurate in PubChem?
Triallyl isocyanurate is a white crystalline solid. (NTP, 1992) Computed by LexiChem 2.6.6 (PubChem release 2019.06.18) InChI=1S/C12H15N3O3/c1-4-7-13-10 (16)14 (8-5-2)12 (18)15 (9-6-3)11 (13)17/h4-6H,1-3,7-9H2
