Silkyboo certified by OEKO TEX Standard 100

All Silkyboo’s beautiful bamboo garments have been certified by OEKO TEX Standard 100, which means all our products have been tested and certified as not containing any harmful substances. Read on to find out about the exact testing, certification procedure and auditing involved to be given this standard.

The Oeko Tex Standard 100 is an independent test and certification system for textile raw, intermediate and end products at all stages of processing. Items that can be certified are yarns, fabrics, manufactured articles (clothing, household textiles, bedding, towels, soft toys)


The tests for harmful substances cover :

  • legally banned and controlled substances
  • chemicals known to be harmful to health (but not yet legally controlled)
  • parameters for health protection

Taken in their entirety, the requirements go far beyond existing national legislation.

Laboratory tests and product classes 

The Oeko Tex testing for harmful substances is always geared towards how the textile will be used. The more closely the product is in contact with the skin, the stricter the human ecology requirements that it must meet.

  • Product class I : textile articles for babies and toddlers up to 3 years old
  • Product class II : textiles used close to the skin (underwear, bedding, t shirts)
  • Product class III : textiles used away from the skin (jackets, coats)
  • Product class IV : furnishing materials (curtains, tablecloths, upholstery)


The prerequisite for textile products to be certified under the Oeko Tex Standard 100 is that all components of an article, without exception, comply with the required criteria – so not only the outer material, but also the sewing threads, linings, prints etc and any non textile accessories such as buttons, zips, rivets etc.

Certification procedure 

  • The company applies to one of the 16 Oeko Tex member institutes for certification, including submitting representative samples of the materials for laboratory testing.
  • The institute in question carries out the laboratory testing. The test report is sent to the applicant.
  • If the testing is successful, the applicant must present a written statement of conformity, declaring that the articles he is producing are identical to the tested samples. Credible evidence of an appropriate quality control system for testing which must be presented to the Oeko Tex institute.
  • Certificates are issued for a period of one year – in Germany and France by the relevant Certification Centre and in other countries by the Oeko Tex member institute in question.

Company audits 

In the interests of providing targeted assistance with optimising operational quality control at the companies around the world that are involved in the Oeko Tex system, a compulsory element of the certification process is for the Oeko Tex member institutes to carry out an audit of the company applying for certification. This monitoring of the company takes place immediately before or shortly after the certificate has been issued and is repeated every three years.

Control testing

The Oeko Tex Association conducts annual control testing of certified products, at a rate of at least 25% of all certificates issued. It tests articles bearing the Oeko Tex Label that are available in retail shops and also samples of materials from factories. In addition, independent auditors carry out random checks of companies holding Oeko Tex certificates, in the form of unannounced inspections.
