410 JOURNAL OF TI-IE SOCIETY OF COSMETIC CHEMISTS independent tests should be carried out by small selected Panels who are concerned only with preference of style of package and preference for ease of use from one type of package rather than another, but this Panel is not concerned with the actual user evaluation of the product. You will, I trust, realise that in this short talk I am unable to cover fully the subject of testing prior to marketing a new product. There are many extra tests which must be laid down for special products or special packing for example, I would not be satisfied with a product of the aerosol type if it had been subjected only to the tests I have described. Further, some of the tests I have spoken of would not be applicable to products of dissimilar nature to the emulsion samples taken. The object of this talk is to instil a line of thought into those of my audience who have not, perhaps, hitherto given due consideration to planned testing of new products prior to marketing, and my talk will have achieved its object if I leave the following thought in your mind. Such planning may cost several days of labour plus 30 days of waiting with a few hours of observation, and necessitates written reports but this is a small price to pay when set against the costs which can arise through inadequate experimental work and which are involved in the exchange of faulty stock a few months after the introduction of a new product plus the undeterminable cost of loss of goodwill. SOCIETY OF COSMETIC CHEMISTS OF GREAT BRITAIN DIPLOMA EXAMINATION, 195f) This examination was held at Acton Technical College on Monday and Wednesday, June 25 and 27, 1956. Two three-hour papers were set to candidates who had satisfactorily attended a three-year course covering the syllabus for the Diploma and had passed the session examinations held at the end of the first and second years. PAPER ONE 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. Write a short account of the emulsifying agents used in toilet and cosmetic preparations.
