OEKO-TEX® Standard 100

1.What is OEKO-TEX® Standards 100?

The OEKO-TEX® standards 100 is developed and managed by the International OEKO-TEX® Association, a group of 16 textile research and test institutes in Europe and Japan, with representative agencies and contact offices in over 60 countries worldwide.

Products that pass the test in this system are allowed to carry a certification label that guarantees to the consumers that the product does not contain harmful substances at levels that can be dangerous to the human body. No matter beddings or sleepwears, most of Mommesilk's products own the OEKO certification and are safe and healthy for your skin.


OEKO-TEX® Standard 100 applies throughout the textile industry and its scope covers textile and leather items at all levels of production, including textile and non-textile accessories. The standard is also applicable to mattresses, feathers and downs, foams, upholstery, and others material with similar characteristics.

OEKO-TEX® products classes are divided based on their intended use:

Class I: Textiles and textile toys for babies and small children up to the age of three, e.g. underwear, romper suits, bed linen, bedding, soft toys etc. (43% of all certificates.)

Class II: Textiles having a large part of their surface in direct contact with the skin, e.g. underwear, bed linen, terry goods, shirts, blouses etc. (53% of all certificates.)

Class III: Textiles which do not come into contact with the skin, or only have a small part of their surface in contact with the skin, e.g. jackets, coats, interlining materials etc. (1% of all certificates.)

Class IV: Furnishing materials for decorative purposes such as table linen and curtains, but also textile wall and floor coverings etc. (3% of all certificates.)

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 fulfill.

Mommesilk has obtained Oeko-Tex Standard 100 Class II certification. This means our product passed a highly reliable test consisting of over 100 strict test standards determined by the above research institutions.

An OEKO-TEX® certificate is valid for 12 months. At the end of this time, it can be renewed for another year. This approach is recommended to ensure continuous product safety and smooth processes all along the textile production chain.
