Organic substances are flammable substances which contain elements such as sulfur, phosphorus and nitrogen, which have carbon, hydrogen and oxygen in their structure, have low melting and boiling points, have high molecular weights and are less soluble in water. It is important to know the structural properties of these organic compounds, ie properties and contents such as solubility, volatility, density and hydrophobicity. This is because it is possible to understand and control its effects.

The Ministry of Customs and Trade issued a Communiqué on Market Surveillance for the Hazardous Chemical Content of Some Consumer Products in 2015. With this legal regulation, certain restrictions on the use of hazardous chemicals used in certain consumer products placed on the market and included in the annex of the communiqué have been introduced.

Restrictions on textile and leather products in the annex of the Communiqué are included under the title of Organostanic Compounds (TBT and DBT). According to this,

• Tributyltin (TBT) compounds will not be used in products such that the tin content is higher than 0.1 by weight.
• Dibutyltin (DBT) compounds will not be used in mixtures and commercially available products with tin content higher than 0.1 by weight.

Tributyltin (TBT) is used in textile sector to prevent bacteria formation and bad odors caused by sweating in socks and sportswear. Some tinned organic compounds are used in PVC products. The high values ​​of these compounds show toxic effect. These substances absorbed through the skin cause reproductive disorders.

For the protection of consumers' health and safety, it is important to quantify TBT, DBT and other tinned organic compounds in textile products. These tests and analyzes are carried out by authorized laboratories. These studies are based on the following standards:

• TS EN ISO 17353 Water quality - Determination of tinned organic compounds - Gas chromatography method
• DIN 38407-13 German standard methods for the detection of water, wastewater and sludge - Co-identifiable substances (group F) - Part 13: Determination of selected organotin compounds by gas chromatography
