In our previous publication identified several elements allergens that can cause contact dermatitis. Many of these elements, although not included in the composition of the products are used in the manufacture of textile articles that we use and wear in everyday life.


The answer can only be given through the certification of products and raw materials and technical tests.

In Europe, one of the main certifications conferred is the standard 100 by OEKO-TEX®.

Ensure Confidence in textiles is one of the main objectives of this certification.


"THE STANDARD 100 by OEKO-TEX® is an international certification system, consistent, for raw materials, intermediate and end products of the textile sector at all stages of processing. The goal is to achieve exempted products of substances harmful to human health."

"The list of criteria covers tests to legally banned and regulated substances, chemical substances with harmful effects to health and other essential parameters in terms of prevention to human health. The tests are performed exclusively by research institutes and textile and authorized test, independent and professional competence proven."

How it works?

"The fundamental basis is the modular system OEKO-TEX®: The certifications are possible in all phases of the textile chain, being that the intermediate certificates are recognized.

Products and groups of articles that have been successfully tested can be advertised and marketed with the label OEKO-TEX®. "Confidence in textiles" is a synonym for responsible textile production - from the raw material to the final product that is exposed in the shops. It is a guarantee for the industry, for the trade and to consumers ."

What are the classes?

The certification OEKO-TEX® is performed by classes of products. In this way were created four classes:

The product class I - Textiles and textile materials toys for babies and children up to three years: underwear, babygrows, clothing and other items for bed, soft toys, etc.

The product class II - textiles in that a large part of the surface comes in direct contact with the skin: underwear, pants, shirts, socks, bed linens, articles in Turkish, etc.

The product class III -Textiles that do not come into contact with the skin or in which only a small part of the surface comes in contact with the skin: jackets, coats, billboard, etc.

The product class IV - Materials used for decoration: table linen, curtains, furniture fabrics, etc.

It should be noted that the skintoskin clothing is only produced with raw materials certified in class I.

What are the criteria?

"Since its creation in 1992, the STANDARD 100 by OEKO-TEX® has as main objective the development of a broad set of criteria, limit values and test methods with scientific basis. The list of comprehensive and rigorous criteria of STANDARD 100 by OEKO-TEX®, with several hundreds of individual substances regulated, takes into account:

  • Legally Prohibited substances and regulated as azo dyes, formaldehyde, pentachlorophenol, cadmium, nickel, etc
  • Numerous substances harmful to health, even if they are not legally regulated
  • Requirements of Annex XVII and XIV of the European Regulation on chemical substances REACH, as well as those of the candidate list of SVHC, ECHA that have been deemed relevant by groups of experts of the Association OEKO-TEX® for textiles, clothing and accessories. The discussions and relevant developments are considered as soon as possible and effective way in updates of the list of criteria of STANDARD 100 by OEKO-TEX®
  • Requirements of the US Consumer Product Safety Improvement Acts (CPSIA) concerning lead
  • Various types of substances which are also relevant for the environment.

In this way, with its decades of experience, the STANDARD 100 by OEKO-TEX® ensures the consumer a high and effective product safety."

What other certifications can be found?

The Global Organic Textile Standard" - GOTS is a certification that can only be found in textile products containing at least 70% of organic fibers. All chemicals such as dyes and auxiliaries used must meet certain environmental criteria and toxicological tests. The choice of accessories is also limited in accordance with the ecological aspects. For manufacturers is required the existence of an installation of wastewater treatment, where there are processes with water. This certification also requires the fulfilment of certain social criteria.


In addition to the certifications mentioned, some markets require certain tests with the objective of guaranteeing the absence of hazardous substances: determination of the PH of the aqueous extract, determination of formaldehyde, discoloration of textiles (sweat and saliva), biocompatibility, among others.

In fact, the analysis of formaldehyde in textile substrates has gained a great importance due to the problems that this compound can bring to human health.

On the other hand, there is also a major concern when the articles intended for babies / children, being that the color fastness of textiles to saliva testing is particularly important. This test uses an artificial saliva and has as its purpose to determine if the colors may be transferred from the textile industry to the mouth.

As has been said, the raw materials in the origin of skintoskin® products are certified by oeko-tex class 1. In addition, there are several tests that attest to the safety and reliability of our products. Therefore, do not hesitate to consult here our solutions to the Eczema
