Description
Benzoic acid appears as a white crystalline solid. Slightly soluble in water. The primary hazard is the potential for environmental damage if released. Immediate steps should be taken to limit spread to the environment. Used to make other chemicals, as a food preservative, and for other uses.;DryPowder; Liquid; OtherSolid; PelletsLargeCrystals;White crystalline powder;Solid;Solid;WHITE CRYSTALS OR POWDER.;white crystal scales or needles with a faint urine, almond odour
