SEM 1: Excipient: sucrose octaacetate; manufacturer: Sigma-Aldrich Inc.; LD50 (rabbit, skin): >5 g/kg lot no.: RS33841’08; magnification: 100; voltage: 5 kV. (3) LD50 (rat, oral): >5 g/kg

15 Handling Precautions Observe normal precautions appropriate to the circumstances and quantity of the material handled. When heated to decomposition, sucrose octaacetate emits acrid smoke and irritating vapors. Compatible chemical-resistant gloves and eye safety goggles are recommended. Respiratory protection is not required, but dust masks may be used for protection from nuisance levels of dust.

16 Regulatory Status GRAS listed. Approved by the FDA as both a direct and an indirect food additive, and as a nail-biting deterrent for over-the-counter drug products.(4)

SEM 2: Excipient: sucrose octaacetate; manufacturer: Sigma-Aldrich Inc.; 18 Comments lot no.: RS33841’08; magnification: 500; voltage: 5 kV. Sucrose octaacetate is a naturally occurring substance that has been isolated from plant material: the root of Clematis japonica contains 0.15% of sucrose octaacetate by dry weight. At a concentration of 0.06% sucrose octaacetate renders sugar too bitter for human consumption.(5) The EINECS number for sucrose octaacetate is 204-772-1. The PubChem Compound ID (CID) for sucrose octaacetate is 219904.
