8.3 Production of Emulsion
1) Prepare water, heat to 75°C
2) Mix substances of Phase B and stir until the oils moisten the surfactant, then heat to 75°C
3) Just before emulgation takes place, disperse Phase C into the hot Phase B
4) Absorb Phase B/C into Phase A, homogenize slightly
5) Add Phase D to the above mixture and homogenize strongly
6) Cool to 40°C, stirring constantly
7) While stirring, add Phases E and F, homogenize slightly
8) Cool to 30°C, stirring constantly
8.4 Stability Data
The emulsion DAY 0403 should reach a droplet size of 1-10 micrometers.
The following results were obtained with heat stability tests conducted with that emulsion:
After 1 month After 2 months After 3 months
at 3°C OK OK OK
at 20°C OK OK OK
at 40°C OK OK OK
at 50°C OK Increase of droplet size Separation
Temperature stability tests resulted in no changes in droplet size, viscosity or pH levels except at
50°C.
After one month, no changes occurred at 50°C. After two months an increase of droplet size was
observed. This increase led to the separation of the emulsion after 3 months.
