Hi,

I worked with similar solutions for mammalian tissue research in PA, and they were allowed to pour it down the drain, but I am not sure about NY state law. This was part of a histology core at a university. One of the main ingredients, propylene glycol is regarded as safe when orally consumed in small amounts according to the FDA.

I"d call a waste disposer in NY and ask to be sure.

Hope that helps.

thanks,
Jahan

It is a liquid that is used to preserve dead pigs and our biology department has gallons of it. This mixture consist of water (89%), propylene glycol (10.01%), 2-amino-2-ethyl-1,3- propanediol (0.66%) and 2-Phenoxyethanol (0.33%), according to the SDS.
