Synopsis This paper examines two methods of lipstick bulk manufacture: one via a direct method and the other via stock concentrates. The paper continues with a comparison of two manufactured bulks moulded in three different ways – first by split moulding, secondly by Rotamoulding, and finally by Ejectoret moulding. Full consideration is paid to time, labour and cost standards of each approach and the resultant moulding examined using some novel physical testing methods. The results of these tests are statistically analysed. Finally, on the basis of the gathered data and photomicrographical work a theoretical lipstick structure is proposed by which the results may be explained.
