1.Discolor temperature:190-200'C. 2.Carbonization temperature:225-230'C. 3.Surface tension:47-53dyn/cm(25'C).
Physical and Chemical Properties:
1, Appearance: white or similar to white powder, odorless and tasteless, non-toxic, and slightly hygroscopic.
2, Solubility: hardly dissolves in waterless ethanol, aether or -acetone. Separate, expands, in hot water with temperature about 80°C to 90°C. swiftly dissolves when cool down. The solution is very stable. Gelatin at high temperature. Good humectants with good dispersibility, adhesive, thickener, emulsification, water keep ability and film forming ability and oil resistance. The film formed possesses good toughness, flexibility and transparent. It can dissolve in some organic solvents or some water-organic components. Can be mixed with other emulsification agent due to non hydronium structure but easy salt out. Solution is stabilized at PH2-12.
3,Speciality: excellent wettability, dispersion, adhesion, thichening, emulsification, water retension and non-permeability of oil.
4,Density: 1.3g/cm³.Apparent density: 0.25-0.7g/cm³.
5,Discolor temperature: 190-200°C.
6,Carbonization temperature: 225-230°C.
7,Surface tension: 47-53dyn/cm(25°C).
Main use:
Chemical ingredient MC is widely used as thickener, protective glue, auxiliary emulsification agent, coloring matter, adhesive of tablets or coating forming agent. Oral defecation agent as well as bases collutory and eye drop agent. Main raw materials of Oral defecation agent and eye drop agent. Also, it can be used as framework material. MC can be made to hydrophilic sol framework. Micro hole film coating or multi layer coating film it controlled released matrix agent. MC with low viscosity is ususlly used as emulsification agent of water packed oil emulsion while MC with high viscosity can be used as thickener, adhesive agent suspending agent and tablets agglutinate. MC can also be mixed with HPMC as film coating of tablets.
Packing, transport and storage:
25kg/barrel. Keep dry where good ventilated. Do not wet, and keep froom sunshine when transport.
