Chem. 21. 719-800 (1970) ¸ 1970 Society of Cosmetic Chemists of Great Britatn The hygienic manufacture and preservation of toiletries and cosmetics ISSUED BY THE COUNCIL OF THE SOCIETY OF COSMETIC CHEMISTS OF GREAT BRITAIN A monograph prepared by a working party comprising:- Chairman: N. J. Van A bb• Members: H. Dixon O. Hughes R. C. S. Woodroffe Synopsis--This is a monograph prepared by a working party on behalf of the Society of Cosmetic Chemists of Great Britain and discusses in detail the complex factors influencing HYGIENIC MANUFACTURE and MICROBIAL CONTAMINATION. It does not prescribe standards, since the indusfry's Code of Good Practice is dealing with this aspect, but it suggests a full range of TESTING procedures. The problem of selecting PRESERVATIVES is discussed fully and METHODS for confirming preservative activity are described. The monograph also offers advice on the DESIGN and operation of MANUFACTURING PROCESSES to minimise CONTAMINATION. 719

720 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS Preface In December 1967, the Society of Cosmetic Chemists of Great Britain and the Toilet Preparations Federation set up a Select Committee of three members of each body with the following terms of reference:-- "To investigate and report upon the desirability and/or advisability of recommending legislative control in the interests of public safety, as to the ingredients in and composition of toilet preparations and the uses for which they are promoted and to recommend the form and nature of such control, bearing in mind, in addition, international harmonization of such control." The Committee completed the production of a Code of Good Practice early in 1970. The original text of this forms Appendix A of this monograph. The Select Committee will be publishing an appendix to the Code setting standards for hygiene and microbiological safety, and may amend these from time to time. Readers are urged to obtain a set of these as soon as they are available to use in conjunction with this monograph. As the Select Committee felt it was not appropriate for it to give guidance on methodology, the Society of Cosmetic Chemists of Great Britain are publishing this monograph as an aid to their own members and to any other interested scientists in ensuring adherence to the standards laid down from time to time in the Code of Good Manufacturing Practice.
