OEKO-TEX® recognises that chemical recipes including bills of substances (BoS) are highly valued, proprietary information. However, OEKO-TEX® requires the publication of all constituent substances and known contaminants / by-products that are regulated by OEKO-TEX® or that are classified as hazardous in accordance with GHS or article 57 of the REACH regulation 1907/2006. By declaring all constituent substances and contaminants, the testing effort is reduced as are the costs for the Analytical Verification of the certification process. The information a chemical producer provides is encrypted and stored by the certifying institute and OEKO-TEX®.

The certification of a chemical with OEKO-TEX® ECO PASSPORT or an entry by ACP in the ACP-List of OEKO-TEX® gives the right to refer to OEKO-TEX® STANDARD 100 or other OEKO-TEX® standards where applicable. Without this certification or listing, OEKO-TEX® has no possibility to verify the suitability of this chemical for the use in mentioned context. In such cases, OEKO-TEX® marks are prohibited to be used in any form in direct relation to specific products by the chemical manufacturer or seller. If a chemical manufacturer or seller, however, chooses to refer to OEKO-TEX® standards via a text reference, it is considered as a mere self-declaration by the chemical manufacturer or seller. The chemical manufacturer or seller shall highlight any “self-declarations” regarding the suitability to OEKO-TEX® STANDARD 100 as an “unverified self-declaration”. Under no circumstances shall such claims be perceived as having been made in the name of or on behalf of OEKO-TEX®. OEKO-TEX® does not accept any liability whatsoever in such cases and any such claim shall not use the OEKO-TEX® trademarks.
