Analysis of Siloxane (D4, D5 and D6) in Cosmetics

Organosiloxanes are widely used in personal care products because they provide the desired properties in cosmetic products. However, the European Chemicals Agency (ECHA) recommends restricting the three siloxane compounds allowed in the wash, such as shampoos, conditioners, and body lotions. These are octamethylcyclotetrasiloxane (D4), decamethylcyclotetrasiloxane (D5) and dodesamethylcyclohexasiloxane (D6) compounds. These compounds are cyclic volatile methyl siloxane substances containing four, five and six siloxane groups, respectively, and they have a smoothing and refreshing effect in cosmetic products. with is preferred. As of 2020, the use of D4 and D5 compounds in products that need to be rinsed has been banned as considered among chemicals harmful to human health.

These are high production volume substances that have been the subject of activities that have been in hazard assessment and risk management for several years in European Union countries. Studies have shown that these compounds cause great damage to the environment, especially the marine ecosystem, as well as human health. In terms of human health, these compounds are known to interfere with hormone function and damage the liver. Therefore, these compounds are considered chemicals of high concern.

In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. Among the numerous tests performed in this context, there are also siloxane (D4, D5 and D6) analysis services in cosmetics.
