Silicone Oil Emulsion |
| 配方组成： |
Sodium Hydroxide (10% sol'n.)/6.0
"Carbopol" 934/2.0
Water/200.0
Brookfield Visc., 20 rpm---18,000 mPa.s or cP
Dodecylamine/1.0
"Dow Corning" 200 Fluid/200.0
pH---7.0 |
| 配制方法： |
Carefully disperse the "Carbopol" 934 resin in the water and mix to a thin, cloudy dispersion without lumps. Add the sodium hydroxide and then the amine with mild agitation. The dispersion will gel immediately.
Add the "Dow Corning" 200 Fluid in a slow, steady stream with good mixing. A white, stable emulsion forms immediately.
Note: The emulsion contains 50% silicone oil and 0.5% "Carbopol" 934 resin. Lower viscosity, stable emulsions can also be prepared by using lower concentrations of "Carbopol" 934 resin and proportionately less neutralizing agent, or preferably, by using "Carbopol" 941 resin and neutralizing agent. The formulation also works with the different viscosity grades of similar silicone fluids. |
