COMMISSION DECISION

of 28 April 2011

on establishing the ecological criteria for the award of the EU Ecolabel to detergents for dishwashers

(notified under document C(2011) 2806)

(Text with EEA relevance)

(2011/263/EU)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 66/2010 of the European Parliament and of the Council of 25 November 2009 on the EU Ecolabel (1), and in particular Article 8(2) thereof,

After consulting the European Union Ecolabelling Board,

Whereas:

(1)

Under Regulation (EC) No 66/2010, the EU Ecolabel may be awarded to those products with a reduced environmental impact during their entire life cycle.

(2)

Regulation (EC) No 66/2010 provides that specific EU Ecolabel criteria are to be established according to product groups.

(3)

Commission Decision 1999/427/EC (2) has established the ecological criteria as well as the related assessment and verification requirements for detergents for dishwashers. Following the review of the criteria set out in that Decision, Commission Decision 2003/31/EC (3) has established revised criteria which are valid until 30 April 2011.

(4)

Those criteria have been further reviewed in the light of technological developments. It results from the review that it is necessary to modify the definition of the product group so as to include a new sub-product group and to establish new criteria. Those new criteria, as well as the related assessment and verification requirements, should be valid for 4 years from the date of adoption of this Decision.

(5)

Decision 2003/31/EC should therefore be replaced for reasons of clarity.

(6)

A transitional period should be allowed for producers whose products have been awarded the Ecolabel for detergents for dishwashers on the basis of the criteria set out in Decision 2003/31/EC, so that they have sufficient time to adapt their products to comply with the revised criteria and requirements. Producers should also be allowed to submit applications based on the criteria set out in Decision 2003/31/EC or on the criteria set out in this Decision until the lapse of validity of that Decision.

(7)

The measures provided for in this Decision are in accordance with the opinion of the Committee established by Article 16 of Regulation (EC) No 66/2010,

HAS ADOPTED THIS DECISION:

Article 1

The product group ‘Detergents for Dishwashers’ shall comprise detergents for dishwashers and products used as rinse aids, whether in powder, liquid or any other form, which are intended to be marketed and used exclusively in automatic domestic dishwashers and in automatic dishwashers for professional use, the size and usage of which is similar to that of domestic dishwashers.

Article 2

For the purpose of this Decision, the following definitions shall apply:

‘Substance’ means a chemical element and their compounds in the natural state or obtained by any production process, including any additive necessary to preserve the stability of the products 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.

Article 3

In order to be awarded the EU Ecolabel under Regulation (EC) No 66/2010, a detergent for dishwashers shall fall within the product group ‘Detergents for Dishwashers’ as defined in Article 1, and shall comply with the criteria set out in the Annex to this Decision.

Article 4

The criteria for the product group ‘Detergents for Dishwashers’, as well as the related assessment and verification requirements, shall be valid for 4 years from the date of adoption of this Decision.

Article 5

For administrative purposes the code number assigned to the product group ‘Detergents for dishwashers’ shall be ‘015’.

Article 6

Decision 2003/31/EC is repealed.

Article 7

1.   By derogation from Article 6, applications for the EU Ecolabel for products falling within the product group ‘Detergents for Dishwashers’ submitted before the date of adoption of this Decision shall be evaluated in accordance with the conditions laid down in Decision 2003/31/EC.

2.   Applications for the EU Ecolabel for products falling within the product group ‘Detergents for Dishwashers’ submitted from the date of adoption of this Decision but by 30 April 2011 at the latest may be based either on the criteria set out in Decision 2003/31/EC or on the criteria set out in this Decision.

Those applications shall be evaluated in accordance with the criteria on which they are based.

3.   Where the Ecolabel is awarded on the basis of an application evaluated according to the criteria set out in Decision 2003/31/EC, that Ecolabel may be used for 12 months from the date of adoption of this Decision.

Article 8

This Decision is addressed to the Member States.

Done at Brussels, 28 April 2011.

ANNEX

FRAMEWORK

The aims of the criteria

The criteria aim, in particular, at promoting products that have a reduced impact on aquatic ecosystems, contain a limited amount of hazardous substances and whose performance has been tested.

CRITERIA

These criteria cover the following areas:

1.

Total chemicals.

2.

Excluded or limited substances or mixtures.

3.

Toxicity to aquatic organisms: Critical Dilution Volume.

4.

Biodegradability of organics.

5.

Washing performance.

6.

Packaging requirements.

7.

Consumer information.

8.

Information appearing on the EU Ecolabel.

1.   Assessment and verification

(a)   Requirements

The specific assessment and verification requirements are indicated within each criterion.

Where the applicant is required to provide declarations, documentation, analyses, test reports, or other evidence to show compliance with the criteria, it is understood that these may originate from the applicant, and/or his supplier(s), and/or their supplier(s), etc., as appropriate.

Where possible, the testing should be performed by laboratories that meet the general requirements of EN ISO 17025 or equivalent.

Where appropriate, test methods other than those indicated for each criterion may be used if the competent body assessing the application accepts their equivalence.

Appendix I makes reference to the detergent ingredient database (DID list) which contains the most widely used ingredients used in detergent formulations. It shall be used for deriving the data for the calculations of the Critical Dilution Volume (CDV) and for the assessment of the biodegradability of the ingredients. For substances not present on the DID list, guidance is given on how to calculate or extrapolate the relevant data. The latest version of the DID list is available from the EU Ecolabel website or via the websites of the individual competent bodies.

Where appropriate, competent bodies may require supporting documentation and may carry out independent verifications.

(b)   Measurement thresholds

Constituent substances the concentration of which exceeds 0,010 % by weight of the preparation shall comply with the ecological criteria.

For preservatives, colouring agents and fragrance compliance with the criteria is required regardless of their concentration except for criterion 2(b) on the content of hazardous substances and mixtures.

Ingoing substances are defined as all substances in the product including additives (e.g. preservatives or stabilizers) in the ingredients. Impurities resulting from the raw material production, which are present in concentrations > 0,010 % by weight of the final formulation shall also comply with the criteria.

If the product has a water-soluble foil intended not to be removed before washing, the foil must be considered to be part of the product formulation in all requirements.

2.   Functional unit

The functional unit shall be the quantity of product required to wash 12 place settings with a standard soil (as defined by DIN or ISO standards).

3.   Reference dosage

The dosage recommended by the manufacturer to consumers for normally soiled dishes and 12 place settings is taken as a reference dosage under standard conditions, as laid down in the IKW washing performance test referred to in criterion 5.

Requirements relating to assessment and verification of (2) Functional unit and (3) Reference dosage: The full formulation comprising trade name, chemical name, CAS No, DID No (1), ingoing quantity including and excluding water, and function of all the ingoing ingredients (regardless of concentration) in the product must be submitted to the competent body. A sample of the artwork including dosage recommendations must be submitted to the competent body.

Safety data sheets for each ingredient shall be submitted to the competent body in accordance with Regulation (EC) No 1907/2006 of the European Parliament and of the Council (2).

The DID list can be found on the EU Ecolabel website: http://ec.europa.eu/environment/ecolabel/ecolabelled_products/categories/did_list_en.htm

Appendix I

Detergents Ingredients Database (DID) list

The DID list (Part A) is a list containing information of the aquatic toxicity and biodegradability of ingredients typically used in detergent formulations. The list includes information on the toxicity and biodegradability of a range of substances used in washing and cleaning products. The list is not comprehensive, but guidance is given in Part B of the DID list concerning the determination of the relevant calculation parameters for substances not present on the DID list (e.g. the Toxicity Factor (TF) and degradation factor (DF), which are used for calculation of the critical dilution volume). The list is a generic source of information and substances present on the DID list are not automatically approved for use in EU Ecolabelled products. The DID list (Parts A and B) can be found on the EU Ecolabel website.

For substances with no data regarding aquatic toxicity and degradability, structure analogies with similar substances may be used to assess the TF and DF. Such structure analogies shall be approved by the competent body granting the EU Ecolabel license. Alternatively, a worst-case approach shall be applied, using the parameters below:

Documentation of ready biodegradability

The following test methods for ready biodegradability shall be used:

(1)

Until 1 December 2010 and during transition period from 1 December 2010 to 1 December 2015:

 

The test methods for ready biodegradability provided for in Directive 67/548/EEC, in particular the methods detailed in Annex V.C4 to that Directive, or their equivalent OECD 301 A-F test methods, or their equivalent ISO tests.

 

The 10 days window principle shall not apply for surfactants. The pass levels shall be 70 % for the tests referred to in Annex V.C4-A and C4-B to Directive 67/548/EEC (and their equivalent OECD 301 A and E tests and ISO equivalents), and shall be 60 % for tests C4-C, D, E and F (and their equivalent OECD 301 B, C, D and F tests and ISO equivalents).

(2)

After 1 December 2015 and during transition period from 1 December 2010 to 1 December 2015:

The test methods provided for in Regulation (EC) No 1272/2008.

Documentation of anaerobic biodegradability

The reference test for anaerobic degradability shall be EN ISO 11734, ECETOC No 28 (June 1988), OECD 311 or an equivalent test method, with the requirement of 60 % ultimate degradability under anaerobic conditions. Test methods simulating the conditions in a relevant anaerobic environment may also be used to document that 60 % ultimate degradability has been attained under anaerobic conditions.

Extrapolation for substances not listed in the DID-list

Where the ingredients that are not listed in the DID-list the following approach may be used to provide the necessary documentation of anaerobic biodegradability:

(1)

Apply reasonable extrapolation. Use test results obtained with one raw material to extrapolate the ultimate anaerobic degradability of structurally related surfactants. Where anaerobic biodegradability has been confirmed for a surfactant (or a group of homologues) according to the DID-list, it can be assumed that a similar type of surfactant is also anaerobically biodegradable (e.g. C12-15 A 1-3 EO sulphate [DID No 8] is anaerobically biodegradable, and a similar anaerobic biodegradability may also be assumed for C12-15 A 6 EO sulphate). Where anaerobic biodegradability has been confirmed for a surfactant by use of an appropriate test method, it can be assumed that a similar type of surfactant is also anaerobically biodegradable (e.g. literature data confirming the anaerobic biodegradability of surfactants belonging to the group alkyl ester ammonium salts may be used as documentation for a similar anaerobic biodegradability of other quaternary ammonium salts containing ester-linkages in the alkyl chain(s)).

Perform screening test for anaerobic degradability. If new testing is necessary, perform a screening test by use of EN ISO 11734, ECETOC No 28 (June 1988), OECD 311 or an equivalent method.

(3)

Perform low-dosage degradability test. If new testing is necessary, and in the case of experimental problems in the screening test (e.g. inhibition due to toxicity of test substance), repeat testing by using a low dosage of surfactant and monitor degradation by 14C measurements or chemical analyses. Testing at low dosages may be performed by use of OECD 308 (August 2000) or an equivalent method.
