name: magnesium stearate
second, the formula: c36h70o4mg
third, weight: 591
fourth, the nature: the white powder, greasy feeling, a slight smell of grease, soluble in hot ethanol, the case stearic acid decomposition and the corresponding magnesium salts.
five quality indicators:
appearance: white powder chloride%: ≤ .0.15
6.7 to 7.5% magnesium sulfate%: ≤ 0.6
moisture%: ≤ 4 molysite%: ≤ 0.01
melting point °c: ≥ 88.5 heavy metals (ppm): ≤ 5
free acid%: ≤ 4% fineness (through 200 mesh): ≥ 99
six uses: it can be used as a non-toxic pvc heat stabilizers and lubricants, as well as cosmetics flour, lubricate skin ointment and medicine tablets materials (lubricants, anti-blocking agents, flow aids), the product is bakelite powder can make it in the lubrication bright and transparent. flat paint is also used as a transparent agent.
