Abstract
A novel process for the manufacture of a lipstick is described which comprises melting a combination of colour pellets together with a measured amount of an oil blend with mixing to give a lipstick base composition and moulding said base composition into a lipstick of a predetermined colour. A colour pellet comprises: 1-50% by weight of a wax component; b) 30-65% by weight of an oil component; and c) 10-35% by weight of a pigment and/or a pearlising agent. A kit of parts suitable for implementing the process is described. The process is particularly suitable for the clean and efficient manufacture of lipsticks, of a wide range of colour, at the point of sale.
