(Received ß loth December 1959) SOCIETY OF COSMETIC CHEMISTS OF GREAT BRITAIN Third Year Diploma Examination BRU'NEL COLLEGE PAPER I (Monday, 22nd June 1959) Candidates must answer Question 1 and any FOUR other questions. Do not attempt to answer more than five questions, including Question 1. Candidates should commence each question on a separate sheet of paper. 1. What are the chief characteristics of the two-phase system in a pressurized pack ? Illustrate this diagrammatically. Discuss the characteristics which determine whether a Surface Spray or a Space Spray will result. Suggest a formula for a Hair Lacquer (Surface Spray) and a Room Deodorant (Space Spray).
