Procedure<
/strong> |
Phase A – Add
Phase A to main
vessel with shear
mixing. Begin
heating to 75-80°C.
Phase B – In a
separate vessel, add
Phase B with shear
mixing and begin
heating to 75-80°C.
Phase C – When
Phase B reaches
desired temperature,
add Phase C to Phase
B and continue
mixing with heat to
75-80°C. Hold heat
and ensure
uniformity of
sunscreens. Once
both vessels reach
75-80°C add Phase
BC to Phase A with
high shear mixing.
Begin cool down.
Phase D – Premix
Phase D in a
separate vessel.
When main vessel has
cooled to 45-50°C
add Phase D to main
vessel and continue
mixing until
uniform. Phase E –
Add Phase E to main
vessel and continue
shear mixing until
uniform. Phase F –
When batch has
cooled below 40°C,
add Phase F under
high shear mixing.
Note: Allot time for
batch to thicken and
reach uniformity.
Transfer to final
container. |
