Surface Active Agents - Bio-based surfactants - Requirements and test methods
This document sets out requirements for bio-based surfactants in terms of properties, limits, application classes and test methods. It establishes the characteristics and details for assessment of bio-based surfactants as to whether they:
— are fit for purpose in terms of performance related properties;
— comply with the requirements regarding the health, safety and environment which apply to general surfactants;
— are derived from a certain minimum percentage of biomass; and
— comply with at least similar sustainability criteria as comparable (non-bio-based) surfactants.
The criteria of the regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) [11] also apply to bio-based surfactants.
NOTE EN 16575 defines the term “bio-based” as derived from biomass and clarifies that “bio-based” does not imply “biodegradable”. In addition, “biodegradable” does not necessarily imply the use of “bio-based” material.
Grenzflächenaktive Stoffe - Bio-basierte Tenside - Anforderungen und Prüfverfahren
Dieses Dokument legt die Anforderungen für biobasierte Tenside in Bezug auf die Eigenschaften, Grenzen, Anwendungsklassen und Prüfverfahren fest. Es legt die Merkmale und Details zur Bewertung biobasierter Tenside fest, um zu bewerten ob diese:
- im Hinblick auf die leistungsbezogenen Eigenschaften geeignet sind;
- mit den Anforderungen in Bezug auf Gesundheit, Sicherheit und Umwelt übereinstimmen, die für allgemeine oberflächenaktive Substanzen gelten;
- von einer bestimmten Mindest-Prozentzahl Biomasse abgeleitet sind;
- zumindest ähnliche Nachhaltigkeitskriterien einhalten wie vergleichbare oberflächenaktive (nicht biobasierte) Substanzen.
Die Kriterien für die Regulierung bezüglich Registrierung, Bewertung, Zulassung und Beschränkung von Chemikalien (REACH) [13] gelten auch für biobasierte Tenside.
ANMERKUNG EN 16575 definiert die Bezeichnung "biobasiert" als abgeleitet von Biomasse und macht deutlich, dass "biobasiert" nicht "biologisch abbaubar" impliziert. Zusätzlich impliziert "biologisch abbaubar" nicht unbedingt die Verwendung von "biobasiertem" Material.
Agents de surface Tensioactifs biosourcés Exigences et méthodes d'essais
Le présent document définit les exigences relatives aux propriétés, aux limites, aux classes d'application et aux méthodes d'essai concernant les agents tensioactifs biosourcés. Il fixe les caractéristiques et les informations permettant d'évaluer les agents tensioactifs biosourcés au regard des critères suivants :
- aptitude à l'emploi du point de vue des propriétés en rapport avec les performances ;
- conformité aux exigences en matière de santé, de sécurité et d'environnement, applicables aux agents tensioactifs en général ;
- origine : pourcentage minimal donné de biomasse dont ils sont issus ;
- conformité à des critères de durabilité au moins similaires à ceux d'agents tensioactifs (non biosourcés) comparables.
Les critères du règlement concernant l'enregistrement, l'évaluation et l'autorisation des substances chimiques, ainsi que les restrictions applicables à ces substances (REACH) [13], s'appliquent aussi aux agents tensioactifs biosourcés.
NOTE La définition du terme « biosourcé » dans l'EN 16575 est « issu de la biomasse ». Il est à préciser que le terme « biosourcé » n'est pas synonyme de « biodégradable », la notion de « biodégradabilité » n'impliquant pas nécessairement, par ailleurs, l'utilisation de matière « biosourcée ».

Introduction
Bio-based raw materials have been used for millennia in the manufacture of surfactants, e.g. the first
surfactant used by mankind, was already completely bio-based – soap. With the advent of modern
surfactants in the early 20 Century, petrochemical-based raw materials also became of interest. They
offered the opportunity to tune the surfactant properties, in a broader sense, to their various
applications.The last decades have seen the emergence of new bio-based raw materials for surfactants. Some of the
reasons for the increased interest lie in the bio-based products’ potential benefits in relation to the
depletion of fossil resources and climate change.Acknowledging the need for common standards for bio-based products, the European Commission
issued Mandate M/492 , resulting in a series of standards developed by CEN/TC 411, with a focus on
bio-based products other than food, feed and biomass for energy applications.The standards of CEN/TC 411 “Bio-based products” provide a common basis on the following aspects:
— common terminology ;— bio-based content determination;
— Life Cycle Assessment (LCA) ;
— sustainability aspects ;
— declaration tools.
It is important to understand what the term “bio-based product” covers and how it is being used. The
term “bio-based” means “derived wholly or partly from biomass”. It is essential to characterize the
amount of biomass contained in the product by, for instance, its (total) bio-based content or bio-based
carbon content.The bio-based content of a product itself does not provide information on its environmental impact or
sustainability, which may be assessed through Life Cycle Inventory (LCI), LCA and sustainability
criteria. In addition, transparent and unambiguous communication within bio-based value chains is
facilitated by a harmonized framework for certification and declaration.Breaking down the horizontal standards to bio-based products like bio-based surfactants, the European
Commission issued Mandate M/491 [12], resulting in standards developed by CEN/TC 276. This
European Standard has been developed with the aim to fulfil part of the Mandate to describe the
technical requirements of bio-based surfactants. The criteria for “bio-based surfactants” published in
this European Standard are complementary to the horizontal standards by CEN/TC 411.
1) A mandate is a standardization task embedded in European trade laws. The M/492 Mandate is addressed to
the European Standardization bodies, i.e. CEN, CENELEC and ETSI, for the development of horizontal European
Standards for bio-based products. The M/491 Mandate is addressed to the development of European Standards
for bio-solvents and bio-surfactants.2) EN 16575.

Surfactants are products which have the ability to reduce interfacial/surface tension, wet surfaces,
suspend materials or emulsify oils and fats. In Europe, thousands of producers, manufacturers and
nearly every inhabitant use surfactants every day in consumer or industrial applications. The
surfactant-producing industry is composed of mainly multinationals. Downstream users are found in
multinationals as well as SME's.Surfactants may be produced from both fossil and renewable carbon feedstock (ref. EN 16575 -
vocabulary). The amount of crude oil used for surfactant production is, however, low with less than 1 %
of the total world's crude oil consumption.Finally, the approach for these Technical Reports/Specifications/Standards intends to strengthen and
harmonize the reputation of “bio-based surfactants” and the confidence of the customer in this product
group.An overview and considerations for the compilation of this European Standard can be found in the WI
276071 [1]. It will describe existing raw material sources with regard to their current usage in surface
active agents, their source identification and conformation, and the options for communication same. It
should also include the current work on surfactants regarding their performances, their sustainability,
the LCA approaches and end of life options.---------------------- Page: 7 ----------------------

1 Scope
This European Standard sets requirements for bio-based surfactants in terms of properties, limits,
application classes and test methods. It lays down the characteristics and details for assessment of bio-
based surfactants as to whether they:— are fit for purpose in terms of performance related properties;
— comply with the requirements regarding the health, safety and environment which apply to general
surfactants;— are derived from a certain minimum percentage of biomass; and
— comply with at least similar sustainability criteria as comparable (non-bio-based) surfactants.
The criteria of the regulation on Registration, Evaluation, Authorization and Restriction of Chemicals
(REACH) [11] also apply to bio-based surfactants.NOTE EN 16575 defines the term “bio-based” as derived from biomass and clarifies that “bio-based” does not
imply “biodegradable”. In addition, “biodegradable” does not necessarily imply the use of “bio-based” material.

4 Generalities on surfactantsSurfactants are products which have the ability to reduce interfacial/surface tension, wet surfaces,
suspend materials, or emulsify oils and fats. They make it possible to process, apply, clean or separate
materials. Surfactants are widely used in consumer and professional products and for industrial
applications. Surfactants are typically used on their own or in combination with other surfactants and
other agents to fulfil the requirements of the respective applications.Examples of applications for surfactants are:
— cleaning agent;
— foaming/defoaming agent;
— wetting agent;
— emulsifier;
— viscosity modifier;
— surface tension reducer;
— process aid;
— fabric softener.
NOTE For many applications to perform effectively, surfactants are essential (see for examples the website of
the TEGEWA e.V. (TExtilhilfsmittel” (textile auxiliaries), “GErbstoffe” (tanning agents) and “WAschrohstoffe”
(detergent raw materials)) .5 Performance of surfactants
5.1 Generalities related to performance
Performance and properties of any molecule, including surfactants, is determined by its chemical
structure and not by the origin of its raw materials.This section gives a common set of technical properties characterizing the performance of surfactants
including bio-based surfactants. Due to the absence of international surfactant specification standards,
it is necessary to provide to potential users the means to qualify the bio-based surfactant products,
especially for its technical performance. Additionally, there are a number of other factors which will
determine the acceptance of a surfactant such as the Health, Safety and Environmental properties which
are treated in another section of this document.Surfactants are used in such a wide variety of applications that it is not convenient to evaluate
separately their performance with respect to each application. Therefore, a practical approach is to
