Answer both parts:- a. You have used the manufacturing method detailed below to produce a lipstick, but you

are finding that it is very difficult to make batches of the product consistently the correct colour. When you look closely at the product you discover that the product has lots of specs in it, which are particularly noticeable in the lighter shades in the range. You have also noticed that when the lipsticks are moulded lots of tiny holes form in the bullets. Also the nice large particle size glittery pearls you have added don’t seem to be having the effect you had expected them to have.

Manufacturing Method:-

1) Place the waxes in a jacketed mixing vessel that is fitted with a high shear mixing head

2) Turn on the steam and melt the waxes

3) Place all the oil components of the formulation in a separate mixing vessel and stir into the, with a spatula, the colours (not the pearls)

4) Add the oil colour blend to the main mixing vessel and mix with high shear until homogeneous.

5) Add in the pearls and continue mixing with high shear until homogeneous again.
