Molecular Composition of Nonionic Vesicles Prepared from Span 80 or Span 85 by a Two‐Step Emulsification Method

Journal of Dispersion Science and Technology, 2006
The molecular compositions of the commercial nonionic surfactants Span 80 and Span 85 were analyzed by reversed phase high performance liquid chromatography (HPLC). Both surfactants are mixtures of fatty acid esters, containing monoesters, diesters, triesters, and tetraesters.

Photoluminescent properties of SPAN-80 coated intrinsic and extrinsic ZnO nanostructures

Physica E: Low-dimensional Systems and Nanostructures, 2016
Abstract Semiconductor nanostructures catch the attention due to morphology tunable properties. SPAN-80-Capped intrinsic and extrinsic ZnO nanostructures have been synthesized by the simple wet-chemical synthesis route. Structural behavior (morphology and crystallography) and photoluminescence performance of synthesized nanomaterials have been ...

HLB of Tween 80/Span 80 effects on microemulsion system for methotrexate delivery

This research aimed to studying effects of HLB on microemulsion systems which composed of Tween 80/ Span 80 as surfactants, 1,2-octanediol as a co-surfactant, Isopropyl myristate (IPM) as an oil phase, and acetate buffer pH 5.5 as an aqueous for hydrophilic (methotrexate; MTX) drug delivery. It was found that increasing of HLBs from 6 to 12 resulted in

FORMULATION AND STABILITY EVALUATION OF DICLOFENAC POTASSIUM MICROEMULSION FORMULATION USING TWEEN 80 : SPAN 80 AS SURFACTANT

JURNAL ILMIAH FARMASI AKADEMI FARMASI JEMBER
Diclofenac potassium is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits hydrophobic properties and causes gastrointestinal side effects, necessitating its formulation as a topical microemulsion. This study aimed to investigate the physical stability of diclofenac potassium microemulsions prepared using a Tween 80:Span 80 surfactant mixture (

Influence of the Ratio of Tween 80 to Span 80 on the Quality Parameters of Microemulsions with Sea Buckthorn Oil

Background: Microemulsion (ME) is thermodynamically stable dispersion of oil and water, stabilized by an interfacial film of surfactants along with co-surfactants [1]. The dosage and type of surfactants used in ME directly influence the ME formation size and stability [2].
