Health Hazard
Excerpt from NIOSH Pocket Guide for Starch:
Exposure Routes: Inhalation, ingestion, skin and/or eye contact
Symptoms: Irritation eyes, skin, mucous membrane; cough, chest pain; dermatitis; rhinorrhea (discharge of thin nasal mucus)
Target Organs: Eyes, skin, respiratory system (NIOSH, 2023)
Reactivity Profile
STARCH is combustible. Presents a dust explosion hazard if dispersed as a fine dust in air in sufficient concentrations. Granules swell greatly in water and produce a colloidal suspension. Incompatible with oxidizing agents, acids, iodine, bases. Reacts with nitric acid/sulfuric acid mixtures to give nitrostarch, an explosive.
Belongs to the Following Reactive Group(s)
- Alcohols and Polyols
- Ethers
Potentially Incompatible Absorbents
