Indian StandardUST OF

PlGMENTS AND COLOURANTS FORUSE IN PLASTICS IN CONTACT WITH

FOODSTUFFS, PHARMACEUTICALSAND DRINKING WATER

O. FOREWORD

0.1 This Indian Standard was adopted by the Indian StandardsInstitution on 5 March 1981, after the draft finalized by the PlasncsSectional Committee had been approved by the Petroleum, Coal andRelated Products Division Council.

0.2 The packaging of foodstuffs and pharmaceuticals is essential fortheir conservation, transport and handling. It also avoids contarnmarionand maintains hygienic conditions. There" always a possibIlity oftransfer of part of packaging matertal to the packed matenial due tointimate contact of each other. Therefore, formulation 01 the packagingmaterial must be selected to ensure that any such transfer is at a mini­mum and substances which do migrate f,om package to the packedmaterial cause no toxic hazard on consumption. These considerationsare equally important in case of processing equipment and utensils whichcome 10 contact with food, pharmaceuticals, etc.

0.3 This standard is expected '0 serve as a basic guide on the constitu­tion of the plastics with regard to their colouring matters whicb areconsidered toxicologically safe and not on tbe manner of their actualprocessing or use. The list of pigments and coJourants prescr-ibed inthis standard IS based on the information available through publishedliterature of the French Regulation and other naeronal legislarionreports. The toxicological effects of these colourants have not beeninvestigated so far.

0.3.1 In this standard, limits for copper and ti" have not beenprescribed as copper and tin are not released from metallic pigments totoxic Iimirs.
