Name: Aluminum sulfate
CAS No.: 10043-01-3
HS CODE: 28332200
Chemical formula: Al2(SO4)3

1)Properties: Including anhydrous and hydrous(18 crystal water) type. Usually, the crystal separated out from aqueous solution at the normal temperature is Al2(SO4) 3.18H 2 O; When weathering, the average molecular structure is Al2(SO4)3.14H2O, may appear white powdery, with bright flake or crystalline flakelet, odorless, to change the taste from sweetness to slight astringency.
2)Uses: Solidifying agent(to purify grease and water) and stabilizer in pasteurization of albumin(including: Liquid or refrigerated whole egg, egg white or egg yolk), the maximum allowable use level(FAO/WHO. 1984) is 0.036%.
3)Standard: HG2225-2001
4)State: Flake or powder
