EU Ecolabel award
1. The objective of the Community eco-label award scheme (hereafter referred to as the
Scheme) is to promote products which have the potential to reduce negative environmental
impacts, as compared with the other products in the same product group, thus contributing to
the efficient use of resources and a high level of environmental protection. This objective shall
be pursued through the provision of guidance and accurate, non-deceptive and scientifically
based information to consumers on such products.
The Community Eco-label award scheme is designed to:
- promote products which have a reduced environmental impact compared with
other products in the same product group.
- provide consumers with accurate and scientifically based information and
guidance on products.

ZnO Legislation
Under new EU legislation Zinc Oxide has been
classified as Dangerous to Environment
(N: R50/53 - Very toxic to aquatic organisms,
may cause long-term adverse effects in the
aquatic environment).
This new legislation means that labels bearing
an environmental warning are now required on
products with a zinc oxide content of 25% and
above.

protection/face protection P305 + P351 + P338: IF IN EYES: Rinse cautiously with water
for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing
Hazard
XI: Irritant Risk
36: Irritating to eyes. 52/53: Harmful to aquatic organisms, may cause long-term adverse
effects in the aquatic environment. Safety
26: In case of contact with eyes, rinse immediately with plenty of water and seek medical
advice. 39: Wear eye/face protection. 61: Avoid release to the environment. Refer to
special instructions / safety data sheets.
Used as an anti-foaming- and emulsifying agent in the production of adhesives
TMMD
A study carried out at the Spanish University
of Saragosa showed the presence of TMDD
in 50% of adhesives used in the food industry.
As to the possibility of TMMD migrating to
packaged food the European Adhesives
Industry is conducting a project to establish
whether or not such migration occurs.
TMDD is assigned to Toxicity Class III, which
is a very high rating.

GREEN PERFORMANCE
• For packaging applications used for a few days (then thrown away) both the
impact of the product carbon footprint and the recyclability/biodegradability/
biocompostablility aspects can become important.
• Development of biodegradable adhesives based on renewable resources goes
hand-in-hand with the development of biodegradable plastic products in general.
• Possible application: The use of the hydrolysable (water soluble adhesives) for
bottle labels.
• Advantage: Such an adhesive would improve the ability to recycle plastic and
glass bottles by permitting easy removal of the paper labels.
• The adhesive dissolved in the water would then biologically degrade very easily.

BOD-5: biochemical oxygen demand
Biochemical oxygen demand or BOD = the amount of oxygen
that bacteria need to biologically oxidise the organic compounds
present in wastewater = « natural degradation ».
BOD-5 = biological oxidation over a 5-day period.
To determine the BOD-5, several dilutions in H ² O (containing
« seed-bacteria ») of a test-sample are analyzed for dissolved
oxygen before and after a 5-day incubation period at 20° C in
the dark.
BOD-5 unit = mg O ² /litre.

COD: chemical oxygen demand
Chemical oxygen demand or COD = the amount of oxygen that is
needed to chemically oxidise the organic compounds present in
wastewater = « chemical degradation ».
The COD test is carried out on waste water and/or test sample
diluted with pure water by adding a mixture of bichromate and
sulphuric acid which chemically oxidises all biologically- and non
biologically degradeable organic materials.
COD unit = mg O ² /litre.
BOD-5/COD ratios in relation to the
biodegradeability of adhesives
• The higher the BOD-5/COD ratio (expresed as a percentage)
the more easily will the material degrade biologically. We
have identified 3 classes of products:
• Readily biodegradeable : BOD-5/COD ratio > 50 %:
includes caseins and starches, altough there is an indication
that starches degrade more slowly.
• Moderately biodegradeable: BOD-5/COD ratio between
40 – 50 %.
• Non-biodegradable : BOD-5/COD ratio < 30 %: typical of a
synthetic-base material.

Legal Considerations To the best of our knowledge and experience, the data / information we have provided is
reliable but it does not amount to a statement of assured properties in the context of the
latest regulations issued by the Federal Court of Justice. With regard to the many
options available in terms of alternative applications and operating conditions the data /
information can only be regarded as of a non-binding nature. In each separate case it is
necessary for you to carry out your own trials before large-scale use although, of
course, in that respect our application technology is available to you upon request.
