1 Substance identity and sameness of Oleochemicals M.Mennicken-Meuthen Brussels, 27 April 2015 Peter Greven GmbH & Co.KG

2 Content Short introduction - APAG - Oleochemicals Substance identity qualitative descriptors additional naming increments description of sameness Examples Advantages

3 APAG APAG is the European Oleochemicals and Allied Products Group and represents the European producers of Fatty Acids Glycerine Alcohols Metallic Soaps Fatty Esters

4 Oleochemicals a short introduction Vegetable & Animal Oils and Fats (& Petrochemicals) Processing Oleochemicals & Allied Products Fatty Acids, Glycerine, Alcohols, Fatty Esters, Metallic Soaps Detergents, Soaps, Laundries Softeners, Cosmetics, Pharmaceuticals, lubricating Oils & Greases, Plastics, Paper Recycling, Coatings,.

5 Oleochemicals a short introduction Difference between the types of fatty acids derived from different types of feedstock: degree of saturation carbon chain length distribution Depend on the initial fat or oil used as feedstock But C-chain distribution might not be exclusive for a specific fat or oil C-chain lengths appear between C6 and C24 Vast majority between C12 and C18

6 Few products have a wider range of applications than - Oleochemicals

7 Substance identity qualitative descriptors Qualitative descriptors: Length of carbon chain (carbon number) Saturation Structure (linear or branched) Functional group (position of the group) The chemical identity of the constituents can be described and systematically named by using the following three descriptors: The alkyl descriptor which describes the number of carbon atoms in the carbon-chain length(s) of the alkyl group(s). The functionality descriptor which identifies the functional group of the substance, e.g. amine, hydroxyl group, alcohol, carboxylic acid. The salt descriptor, the cation / anion of any salt, e.g. sodium (Na+), magnesium (Mg2+), carbonate (CO3 2-), chloride (Cl-).

8 Substance identity additional naming increments Additional rules beyond common CAS and IUPAC naming also requested from ECHA to be used for all Oleochemicals: linear branched even numbered or odd numbered Mono/di/tri partial esters saturated unsaturated Current inventory lists use these elements sometimes in a non systematic way CAS Fatty acids, C16-18 CAS Fatty acids, C16-18 and C18-unsatd. CAS Fatty acids, C14-18 and C16-18 unsatd., triesters with trimethylolpropane

9 Substance identity description of sameness Within APAG a compromise was developed which was accepted by the member companies: Implement the additional naming increments via old CAS and new reference substance name The quantitative description is given in the IUCLID description field resulting from the SIEF communication (80 % rule and 10 % rule)

10 EINECS NAME EINECS NAME Qualitative descriptor / EU ECHA NAME

11 Qualitative descriptor / EU ECHA NAME EINECS NAME Quantitative descriptor: SIP plus reference to core CAS (EINECS)

12 EINECS NAME

13 EINECS NAME Qualitative descriptor / EU ECHA NAME EINECS NAME

14 Qualitative descriptor / EU ECHA NAME EINECS NAME Quantitative descriptor: SIP plus reference to core CAS (EINECS)

15 EINECS NAME

16 Advantages Global inventory naming and others will not be changed ( core cas name will be kept) e.g. TSCA, DSL, EINECS, AICS, PICCS, ASIA-PAC, Cosmetic positive list, food contact, pesticides, biocides. In EU additional information to the CAS name will be provided regarding substance to be registered in the reference substance and/or description field (SIP: SUBSTANCE IDENTIFICATION PROFILE) IUPAC rules will be ignored for Oleochemicals by implementing the ECHA rules The link between CAS name and (eco)toxicological studies will be kept All pre-registrations for phase-in substances are kept Identifier of the substance will be kept globally harmonized
