The chemical is corrosive to the skin (GHS Category 1), or likely to be corrosive to the skin. That is, the chemical is a strong acid (pH less than or equal to 2) or base (pH greater than or equal to 11.5), and has high high buffering capacity (if relevant).
Both of the following:
- a suitable in silico prediction for acute toxicity (LD50) of the chemical of greater than 2,000 mg/kg bw/day
- test results from an in vitro study on the chemical or from suitable read across information for acute toxicity (LD50), conducted following an acceptable test guideline for acute oral toxicity, of greater than 300 mg/kg bw
Information that demonstrates the chemical is a high molecular weight polymer that has:
- less than 5% by mass of molecules with molecular weight less than 1,000 g/mol and
- less than 2% by mass of molecules with molecular weight less than 500 g/mol
The chemical's included in the Select Committee on GRAS Substances (SCOGS) Database as a Type 1 conclusion, and the human health exposure expected from the industrial use of the chemical is no higher than the human health exposure expected from food use.
The chemical has been notified to the US FDA GRAS notification program and FDA had no questions about the notifier’s conclusion of GRAS status, and the human health exposure expected from the industrial use of the chemical is no higher than the human health exposure expected from food use.
The chemical is permitted to be used as a food additive according to Schedule 15 of the Australia New Zealand Food Standards Code – Standard 1.3.1 – Food Additives, and the human health exposure expected from the industrial use of the chemical is no higher than the human health exposure expected from food use.
Information that demonstrates the chemical is a substance covered by Entry 9 of Annex V of the REACH Regulation.
A test result from at least one in vivo study on the chemical or from suitable read across information, as detailed below, with the administration route dependent on the most relevant route of exposure (or the oral route if information on the most relevant route is not available):
- conducted following an acceptable test guideline for acute oral toxicity with an LD50 greater than 300 mg/kg bw
- conducted following an acceptable test guideline for acute dermal toxicity with an LD50 greater than1,000 mg/kg bw
- conducted following an acceptable test guideline for acute inhalation toxicity, with an LC50:
- for gases - greater than 2,500 ppmV/4h or
- for vapours - greater than 10 mg/L/4h or
- for dusts/mists/fumes - greater than 1 mg/L/4h
Test results from an in vivo study via the oral route on the chemical or from suitable read across information, conducted following an acceptable test guideline for subacute oral toxicity, with a NOAEL greater than or equal to 1,000 mg/kg bw/day.
