Surface Active Agents - Bio-based surfactants - Requirements and test methods

This Technical Specification 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 (standard) 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.

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 20th 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, resulting in standards developed by CEN/TC 276. This Technical

Specification 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

Technical Specification are complementary to the horizontal standards by CEN/TC 411.

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

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.

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.

1 Scope

This Technical Specification 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 surfactants

Surfactants 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 potentia
