In the production of lipstick compounds, mixtures of different polyethylene glycols, as well as gelatin, glycerol, waxes and colour pigments are used.
Lipstick compounds can consist of emulsions, suspensions or solutions of different active substances and fats.
When producing lipstick compounds, not only hygiene, but also the handling of a wide range of viscosity levels must be taken into consideration.
Innovative process plants are extremely flexible and efficient devices that can produce this performance.
Provided that installation and equipment possibilities for the homogeniser chamber, the recirculation lines and the lid area are available in order to ensure efficient suction, mixing and dosing, optimal batch times can be achieved.
From temperature control and melting of fats, through homogenisation to the incorporation of colour pigments, all production steps in the agitators employed should take place simultaneously. Pressure and vacuum-proof process plants enable processing of ingredients with differing viscosities under aseptic conditions in one homogenisation step. In the case of viscose products, such as the lipstick compounds, excellent radial and vertical mixing must be guaranteed, in order to ensure a homogeneous and uniform distribution of the insoluble colour pigments.
Mechanical equipment specially designed for these processes favours the production of lipstick compounds, as it can provide convenient methods of sucking in or dispersing powders and colour pigments.
By means of the highest possible speeds of the rotor/stator system, these components and colour pigments can be efficiently incorporated in the lipstick compounds.
The colour pigments then no longer need to be pre-milled to reduce their particle size.
Furthermore, the mixer is intended to enable a low-dust processing of volatile powders and colour pigments.
Particular attention should be paid to precise temperature control and thermoregulation of the product-carrying container areas and the pipelines.
The GMP-compliant CIP device should already be installed in the process plant to reduce the lengths of the production cycles.
Special cleaning agents should be used for the cleaning of products with colour pigments.
Due to the intensive treatment of the homogeniser, wear protection for the rotor/stator toothing should be considered when processing colour pigments.
The lipstick compounds are emptied and filled in a flowable state.
