Transcription

1 LOWINOX 22M46-45D dispersion Aqueous preparation of an antioxidant Description LOWINOX 22M46-45D dispersion is a 45% by weight water-based dispersion of the hindered phenolic antioxidant LOWINOX 22M46 stabilizer. Active Ingredient LOWINOX 22M46 stabilizer Chemical Name Phenol, 2,2'-methylenebis[6-(1,1-dimethylethyl)-4-methyl- Synonym 2,2 -Methylenebis(6-t-butyl-4-methylphenol) CAS-Number: EINECS-Number: Formula LOWINOX 22M46 stabilizer Typical physical properties of LOWINOX 22M46-45D dispersion Appearance White liquid Antioxidant content (% weight) 45 Particle Size ( D 50 ) [µm] < C 9,5-10,5

2 Application LOWINOX 22M46-45D dispersion provides the highly efficient antioxidant LOWINOX 22M46 stabilizer in an easy-to-handle water-based liquid form. LOWINOX 22M46 stabilizer is one of the most widely used antioxidants for white, light colored and transparent vulcanates that are based on natural or synthetic rubbers. In light colored vulcanates, LOWINOX 22M46 stabilizer retards the crazing effect caused by exposure to light. LOWINOX 22M46 stabilizer does not influence processing and vulcanizing properties. It exhibits low volatility and migration which makes it suitable for use in POM and ABS. For more detailed advice on applications please contact your local Addivant TM sales representative. General Advantages Liquid form of a highly efficient antioxidant suited for emulsion and dispersion manufacture of polymers Excellent storage stability Adjusted viscosity to assure accurate and easy dosage Water based system with no dust and no VOC (volatile organic compounds) exposure of the workforce All ingredients have broad food contact approvals

3 Food Contact Approval The components of LOWINOX 22M46-45D dispersion can be used in applications that come into contact with food according to the following regulations: LOWINOX 22M46 stabilizer: This compound has broad food contact approvals; for details please contact Addivant TM Regulatory Affairs Polymer Additives. EEC: The substance is listed under Reference No in the 6th amendment of the plastic material directive amending Directive 90/128/EEC (relating to plastic materials and articles intended to come into contact with foodstuffs) with a SML (specific migration limit) of 1.5 mg/kg. USA: - FDA 21 CFR Antioxidants and/or stabilizers for polymers. - FDA 21 CFR Resinous and Polymeric Coatings - FDA 21 CFR (c) Olefin Polymers - FDA 21 CFR Polyoxymethylene copolymer - FDA 21 CFR Polyoxymethylene homopolymer - FDA 21 CFR Rubber articles intended for repeated use. Other Components Emulsifier: USA: - FDA 21 CFR adhesives - FDA 21 CFR resinous & polymeric coatings - FDA 21 CFR components of paper and paperboard in contact with aqueous and fatty foods - FDA 21 CFR components of paper and paperboard in contact with dry food - FDA 21 CFR defoaming agents used in the manufacture of paper and paperboard - FDA 21 CFR cellophane - FDA 21 CFR closures with sealing gaskets for food containers - FDA 21 CFR laminate structures for use at temperatures of 250 F and above

4 - FDA 21 CFR hydroxyethyl cellulose film, water-insoluble - FDA 21 CFR rubber articles intended for repeated use - FDA 21 CFR animal glue Other Components Thickener: The respective compound is used as direct food additive/food ingredient and is generally recognized as safe (GRAS). It can therefore be used in food contact applications as well. Other Components Biocide: EEC: The compound is listed on the draft positive list of additives used in the manufacture of plastic articles and materials intended to come into contact with foodstuffs (the Synoptic Document). A complete dossier for the compound was submitted before the 31/12/2006 for inclusion into the transitional list. It is expected that the substance will be restricted to a specific migration limit of 1.2 mg/kg. Therefore the biocide can continue to be used in accordance with the Framework Regulation and National Legislation and in accordance with Directive 2002/72/EEC once the transitional list is published: Germany BGA XIV for use in plastic dispersions used in food packaging BGA XXI for use in articles prepared from natural or synthetic rubber BGA XXXVI for use in paper, cardboard and pasteboard used in food packaging Spain Resolución de 4.XI.82 listed on Annex 1 modificada por of Royal Decree 1125/1982 Orden de 3.VII.85 The Netherlands Warenwet CAT 33 Warenwet CAT 39 listed on HFDST 2, para 1. (Paper and board for general use) as a slimicide for use only in industrial process waters listed on HFDST 2, para 1. (Paper and board for general use) as a preservative for preservation of coatings only.

The dispersions/emulsions consist of two phases: a finely dispersed polymer stabilizer phase and a continuous aqueous phase. These phases tend to separate and occasionally to discolor if the dispersion/emulsion is exposed to adverse conditions, e.g. excessive heat, frost, light and emulsion breaking or heavily oxidizing chemicals. Therefore the constant quality of Addivant TM dispersions/emulsions can only be guaranteed if the advice given below is thoroughly followed. For additional handling and toxicological information consult the Addivant TM Material Safety Data Sheet. Transport The containers (in general 1000L IBCs) should be placed during transportation in a place where they are protected against: Heat and frost: Direct sunlight: Evaporation: Aggressive chemicals: avoid temperatures below +5 C and above +35 C long distance transport only in covered trucks close container thoroughly close container thoroughly (exhaust gases) Storage For storage the containers should be kept in a place where they are protected against: Heat and frost: Direct sunlight: Evaporation: Aggressive chemicals: avoid temperatures below +5 C and above +35 C long term storage only in warehouses close container thoroughly close container thoroughly (exhaust gases)

6 Handling No phase separation or solidification should occur during the recommended shelf life of the product (6 months) if the above storage measures are taken. Prior to use it is recommended that the dispersion/emulsion is mixed in order to destroy inhomogeneities and to redisperse occasionally separated water appearing at the bottom or the top of the container as a thin layer (according to the density of the dispersed material). If the dispersion is only partly used, the remaining quantities should be stored under the conditions described above. If a single container of product is to be used over a long period of time, care should be taken to avoid exposure to heat, frost and light and conditions promoting evaporation. Repeated opening and improper closing could result in bacterial contamination.
