In the present study, tocotrienol rich fraction (TRF) nanoemulsions were produced as an alternative approach to improve solubility and absorption of tocotrienols. In the present study, droplet size obtained after 10 cycles of homogenization with increasing pressure was found to decrease from 120 to 65.1 nm. Nanoemulsions stabilized with Tween series alone or emulsifier blend Brij 35:Span 80 (0....

A very simple, selective, and fast flow injection spectrophotometeric method is developed for determination of nickel using furildioxime as complexing agent. Micellar solution of brij-35 is employed to solubilize the sparingly soluble complex of Ni-furildioxime in buffered aqueous system (pH-9.00). Under optimized conditions, absorbance is linear from 0.02 to 10 μg mL(-1) using 500 μL sample vo...

In this study, two different non-ionic surfactants have been evaluated as a plasticizer in lithium polymer electrolytes and compared with an organic carbonate-based plasticizer. To that end, molecular weight structure selected (Triton� X-100 Brij�L23) carbonates (EC:DEC1:1) plasticizers electrolytes. The effect of the content, salt content surfactant characteristics on properties such ionic con...

The separation and on-line concentrations of lysergic acid diethylamide (LSD), iso-lysergic acid diethylamide (iso-LSD) and lysergic acid N,N-methylpropylamide (LAMPA) in human urine were investigated by capillary electrophoresis-fluorescence spectroscopy using sodium dodecyl sulfate (SDS) as an anionic surfactant. A number of parameters such as buffer pH, SDS concentration, Brij-30 concentrati...

      In this work we sought to determine whether vesicles (liposomes/niosomes) were able to enhance finasteride concentration in the dermis layer, including the pilosebaceous units (PSU). Such enhancement could be beneficial in the treatment of some androgen-related skin disorders. Hamster flank skin was used to study  <span styl...

Karmosin (E122) bir gıda katkı maddesi olarak genellikle gıda, kozmetik ve ilaçlarda kullanılan boyadır. Bu çalışmada, bulutlanma noktası ekstraksiyonundan (CPE) sonra şurup numunesinde karmosinin (KAR) spektrofotometrik tayini için ekstraksiyon aşamasında Brij 58 kullanılmıştır. Ekstraksiyon sıcaklığı, pH, (yüzey aktif madde) konsantrasyonu Na2SO4 gibi bazı parametreler merkezi kompozit tasarı...
