- Toxicity Summary: The inorganic borates display low acute toxicity. They are either not irritant or mild skin and eye irritants. They are not skin sensitisers, nor are they mutagenic or carcinogenic. The most sensitive endpoints of toxicity are considered to be effects on the reproductive organs, fertility in males, and developmental effects. The doses that cause these effects are far higher than any levels to which the human population could be exposed... /Inorganic borates/ Source: Hazardous Substances Data Bank (HSDB)
