SUBSTANCE IDENTIFICATION

This document provides information on substance identification under REACH, specifically focused on biodiesel substances. It includes a list of biodiesel substances covered under the EBB Biodiesel REACH Consortium Agreement and guidance on substance identification. The document also discusses the REACH Annex VI and provides examples of substance names using the Soap and Detergent Association (SDA) Alkyl-Range Descriptors.

  1. SUBSTANCE IDENTIFICATION Mark BLAINEY EBB Biodiesel Consortium REACH Expert EBB Consortium Technical Committee Conference Call Brussels, May 28th, 2009 EBB BIODIESEL REACH CONSORTIUM

  2. Substance Identification under REACH Substance definition a chemical element and its compounds in the natural state or obtained by any manufacturing process, including any additive necessary to preserve its stability and any impurity deriving from the process used, but excluding any solvent which may be separated without affecting the stability of the substance or changing its composition. Substances on the European market between 1st January 1971 and 18th September 1981 are listed in the European Inventory of Existing Commercial Chemical Substances (EINECS). Pre-registration of phase-in substances on EINECS but then substance identification according to REACH (Annex VI.2 and Guidance on Substance Identification).

  3. Biodiesel Substances Covered under the EBB Biodiesel REACH Consortium Agreement Biodiesel (animal): EINECS 287-322-7 (Fatty acids, animal, unsatd., Me-esters). Biodiesel (animal): EINECS 262-989-7 (Fatty acids, tallow, Me esters). Biodiesel (animal): EINECS 272-743-0 (Tallow, Me esters). Biodiesel (soy): EINECS 272-898-4 (Fatty acids, soya, Me esters). Biodiesel (soy): EINECS 267-055-2 (Soybean oil, Me esters). Biodiesel (rape): EINECS 287-828-8 (Fatty acids, rape-oil, Me esters). Biodiesel (sun): EINECS# 272-900-3 Fatty acids, sunflower-oil, Me esters. Biodiesel (palm): EINECS 293-086-6 (Fatty acids, palm-oil, Me esters). Biodiesel (vegoils): EINECS 273-606-8 (Fatty acids, vegetable-oil, Me esters). Biodiesel (mixtures, general): EINECS 267-007-0 (Fatty acids, C14-18 and C16-18-unsatd., Me esters). Biodiesel (mixtures, general): EINECS 267-015-4 (Fatty acids, C16-18 and C18-unsatd., Me esters). Biodiesel (mixtures, general): EINECS 310-005-2 (Fatty acids, C16-18 and C16-18-unsatd., Me esters).

  4. REACH Annex VI – Identification of the Substance

  5. REACH Annex VI – Identification of the Substance (cont.)

  6. Guidance on Substance Identification: Substance Types Substances can be divided into: Well defined substances: a defined qualitative and quantitative composition. Mono-constituent substances: one main constituent ≥ 80%. Multi-constituent substances: a mixture (reaction mass) of main constituents each between ≥10 and <80%. UVCB substances: Substances of Unknown or Variable composition, Complex reaction products or Biological materials. Variability is relatively large and/or unpredictable.

  7. Guidance on Substance Identification: Substance Types Substance should be identified by: The IUPAC and/or other name and other identifiers The molecular and structural information The chemical composition Normally, the primary name would be the IUPAC name or another well defined internationally accepted name of the substance, including the Soap and Detergent Association (SDA) Alkyl-Range Descriptors.

  8. Soap and Detergent Association (SDA) Alkyl-Range Descriptors System for naming substances derived from natural fats and oils and their synthetic substitutes. Describes long-chain alkyl derivatives based on: an alkyl descriptor (describing the principal long-chain alkyl groups of a substance while optionally disregarding certain minor components); a functionality descriptor (identify the associated functional group(s) a salt descriptor, if necessary. Example: Substance derived from unfractionated or uncombined soybean oil has the alkyl descriptor: C16-18 and C18-unsaturated. The same alkyl descriptor is also used to describe unfractionated or uncombined palm oil, rapeseed oil and sunflower oil. Example: Based on the SDA alkyl descriptor for derivatives of the parent animal fats, the methylesters produced by treatment of tallow, lard, or poultry fat, or combinations of those fats may be consolidated under: SDA Substance Name: C14-C18 and C16-C18 unsaturated alkyl carboxylic acid methyl esters.

  9. Sample Substance Information

  10. Next Steps Analysis of substance composition from EBB REACH consortium members Finalization of substance consolidation: Aim: smallest possible number of substances for registration Concentrate on biodiesel substances, then cover all pre-registered substances Use of consolidated substance list to finalize ‘gap analysis’
