À propos des DEHP

ConvaTec n’utilise plus de DEHP

 

Le plastique polychlorure de vinyle (PVC) est utilisé dans la fabrication de dispositifs médicaux à application cruciale comme l’alimentation entérale, le drainage des plaies et la ventilation des voies respiratoires. Toutefois, ce matériau est dur et friable à la température ambiante. Pour le rendre flexible, il doit être ramolli au moyen d’un additif chimique appelé « plastifiant ».

Les plastifiants utilisés le plus communément de nos jours sont les phtalates.  

Le DEHP (benzène-1,2-dicarboxylate de bis(2-éthylhexyle), appelé également « phtalate de dioctyle » ou DPO, est le phtalate plastifiant qui a été utilisé le plus couramment2 dans l‘industrie des dispositifs médicaux.

 Growing concern over exposure to DEHP

Numerous studies have indicated that phthalates, especially DEHP, may impair testicular testosterone production in rats.1-2 Phthalates have also been associated with adverse reproductive system outcomes in animal tests, including reduced semen quality, altered male genital development and respiratory symptoms.3-11 Recent research provides the first evidence that DEHP can inhibit testosterone production in the adult human testis.11

The ConvaTec Answer

Based on these concerns, ConvaTec is replacing DEHP with DEHT. Despite the similar name, DEHT is not a phthalate.

DEHT (Di-(2-ethylhexyl) terephthalate), also known as dioctyl terephthalate, is a general-purpose non-phthalate plasticizer. It has been available and researched for more than 30 years and has an extensive toxicological profile that demonstrates suitability in applications such as toys, beverage closures and medical devices.

In 2008, SCENIHR – The Scientific Committee on Emerging and Newly Identified Health Risks of the European Commission – analyzed and compared toxicological data of available plasticizer alternatives.1 DEHT was found not to be genotoxic (like DEHP) and does not show reproductive toxicity. At doses where DEHP and other alternatives altered sexual differentiation, DEHT was inactive.1
