OEKO-TEX® Standard 100

OEKO-TEX® is the world’s leading certification of textiles tested for harmful substances. Each garment component has been tested for harmful substances and declared safe; therefore, aligned with our standard of quality at Purest Thread.


What is OEKO-TEX Certified® Apparel?

From the coating on the zippers to the print that is on the garment, every component goes through the testing process to ensure its safety. With everything that goes into producing garments, it is imperative that all apparel components are examined when going the extra step to give the consumer confidence and accreditation of quality. This ensures that no part of the garment is harmful to human or environmental health.


Why It Matters

Unfortunately, the dyeing process of clothing can use harmful substances such as formaldehyde. The OEKO-TEX® certification is designed to ensure that the result of apparel dyeing and wet-processing does not have a negative effect on human or environmental health. This ensures that garments are safe for manufacturers, consumers, and the environment.


The Importance of Non-Toxic Clothing

The sad reality is that many of the garments that are produced use residual dyes, hazardous chemicals, heavy metals, microfibers, and mordants to help bond dyes with fabric. Many of these synthetic dyes, specifically azo dyes, are carcinogenic and are therefore not found in non-toxic cotton. Azo dyes are water-soluble making them easy for skin to absorb and, as a result, may cause skin and eye irritation. Being non-toxic certified guarantees no trace of these harmful chemicals in any of our products.

Even though most countries have banned these toxic dyes, there are still parts of the world that still use these in production to support the high demand of fast fashion. Many countries can’t access clean drinking or bathing water because of the contamination caused by harmful dyes. This effect of apparel production is obviously very harmful and not sustainable, which leads us to be different and prioritize safety by producing non-toxic wholesale clothing.
