Oeko-Tex Standard 100
All Linen Butler pillows and duvets carries the Oeko-Tex Label. The Oeko-Tex
Standard 100 is a globally uniform testing and certification system for textile raw
materials, intermediate and end products at all stages of production.
The tests for harmful substances comprise substances which are prohibited or
regulated by law, chemicals which are known to be harmful to health, and
parameters which are included as a precautionary measure to safeguard health.
A tested textile product is allocated to one of the four Oeko-Tex product
classes based on its intended use. The more intensively a product comes into
contact with the skin, the stricter the human ecological requirements it must fulfil.
Manufacturers are entitled to mark successfully tested products or article groups
with the Oeko-Tex label and to advertise in other forms as long as it has been
proven within the extensive laboratory tests that all components, including
accessories, comply with the specified test criteria without exception. A certificate
which is issued applies for one year and can be renewed as often as required.

Objectives
The testing and certification system of the Oeko-Tex Standard 100 satisfies the
many and varied requirements consumers make of modern textile products and
at the same time takes into account the complex production conditions in the
textile industry: global organisation, a strong tendency towards the international
division of labour, different mentalities with respect to the use of potentially
harmful substances.
• Manufacturing textile products of all types, ecologically harmless for
humans.
• Simplifying and accelerating terms of delivery for manufacturers and
retailers who wish to offer their customers textile products which pose no
risk whatsoever to health.
• A reliable product label for consumers who specifically aim to buy textiles
which are harmless to health.

Testing
The test methods to be used for the Oeko-Tex tests for harmful substances by
the authorised member institutes are summarised in the normative document
"Oeko-Tex Standard 200 – testing procedures".
The laboratory tests currently comprise around 100 test parameters and are
based on international test standards and other recognised testing procedures.
These also include simulation tests, which take into account all possible ways by
which harmful substances could be absorbed into the human body (orally, via the
skin, by inhalation).
The tests involved on a textile depend on the chemicals used at each stage of
processing which result in a qualitative change to the textile. The scope of the
human ecological requirements is based on the intended use of the textile. In
principle, the more intensively a textile comes into contact with the skin, the
stricter the limit values it must fulfil.

Tests for harmful substances
The internationally binding test catalogue according to Oeko-Tex Standard 100 is
based on scientifically proven parameters and is revised annually in line with the
latest legislation and research.
It includes:
• substances which are prohibited by law, such as carcinogenic dyestuffs
• substances which are regulated by law, such as formaldehyde, softeners,
heavy metals or pentachlorophenol
• substances which according to current knowledge are harmful to health,
but which are not yet regulated or prohibited by law, such as pesticides,
allergy-inducing dyestuffs or tin-organic compounds
• parameters such as colourfastness and a skin-friendly pH-value, which
are precautionary measures to safeguard consumers heath
