Abstract

In this work, microencapsulation is undertaken with the coacervation method, using gelatin and gum arabic polymer mixtures. The behaviours of these microcapsules have been investigated by using violet, lemon and peach parfumes in the media of gelatin and gum arabic coacervates which are crosslinked with formaldehyde and formaldehyde/urea. In this investigation, the concentration of parfumes released from microcapsule walls into the carbon tetrachloride medium are measured depending on time. It was observed that the released amount of perfumes decreased with increased amount of formaldehyde in microcapsule wall. The relesed amount of perfumes decreased more by adding urea into formaldehyde medium. The evaluation according to perfume types showed that the released amounts decreased in the following order: violet> lemon>peach.

Özet

Bu çalışmada jelatin ve arap zamkı polimer karışımları kullanarak koaservasyon yöntemi ile mikrokapsüller oluşturulmuştur. Bu mikrokapsullerin formaldehit ve formaldehit/üre ile çapraz bağlı jelatin ve arap zamkı koaservatlan ortamındaki davranışları, menekşe, limon ve şeftali parfümleri kullanılarak incelenmiştir. Yapılan bu incelemede, parfümlerin mikrokapsül duvarından zamana bağlı olarak karbon tetra klorür ortamına salınan konsantrasyonları ölçülmüştür. Mikrokapsül duvarındaki formaldehit miktarı arttıkça mikrokapsüllerden salınan parfüm konsantrasyonunun azaldığı, formaldehit ortamına üre ilave edildiğinde ise bu salınmanın daha da azaldığı gözlenmiştir. Parfüm cinsine göre yapılan değerlendirmede ise, salınmanın menekşe > limon > şeftali yönünde azaldığı belirlenmiştir.
