Tween 80 and Triton A20 are two water-dispersible, non-ionic, surface-active agents which favor dispersed growth of tubercle bacilli in aqueous media probably by wetting the bacterial surface. Tween 80 is a polyoxyethylene ester of sorbitan monooleate and is liable to enzymatic hydrolysis by lipases. Triton A20 in an arylalkyl polyether of phenol which appears resistant to the known enzymes of ...
Article history: Received 8 January 2014 Received 30 April 2014 Accepted 30 April 2014 Available online 16 October 2014 Climate change is supposed tohave influences onwater quality and ecosystem.However, only few studies have assessed the effect of climate change on environmental toxic contaminants in urban lakes. In this research, response of several toxic contaminants in twelve urban lakes in...
AIM γ-oryzanol (OZ) is a rich source of commercially-important bioactive phytochemicals, most of them of interest in nutrition, pharmacy and cosmetics. However, the poor solubility of OZ limited the use. In the paper, ultraviolet-visible (UV-Vis) analysis was conducted to analysis the solubilization of OZ under combined use of Tween 80 in vitro. In addition, to further confirm the solubilizing ...
Drug resistance has become a main obstacle for the effective treatment of lung cancer. To address this problem, a novel biocompatible nanoscale package, poly(d,l-lactide-co-glycolide)-Tween 80, was designed and synthesized to overcome paclitaxel (PTX) resistance in a PTX-resistant human lung cancer cell line. The poly(d,l-lactide-co-glycolide) (PLGA)-Tween 80 nanoparticles (NPs) could efficient...
The nonionic surfactant Tween 20 [polyoxyethylene(20)sorbitan monolaurate] is one of the more frequently encountered xenobiotics. Surface-active agents of the Tween type are used as constituents of cleaning agents, as food additives and as vehicles in the drug and cosmetic industry [1], Because of its good solubilizing properties Tween 20 has been used in teratological experiments as a solubili...
Smegmatocin, a protein produced by Mycobacterium smegmatis ATCC 14468, was found to have an esterase activity, hydrolyzing Tween 80, polyoxyethylene sorbitan monooleate, added to the assay medium for various "bacteriocins" from mycobacteria. Because M. diernhoferi ATCC 19340 (indicator strain for smegmatocin) is highly susceptible to oleic acid and smegmatocin requires Tween 80 for manifestatio...
A Tween 80 hydrolysis test substrate was found to be stable at room temperature for at least 6 months.
MacConkey agar modified with Tween 80, and deoxyribonuclease agar modified with Tween 80 plus sorbitol were used in differentiating Yersinia enterocolitica colonies from other lactose-negative bacterial colonies.
Kencur ( Kaempferia galanga L.) rhizome ethanol extract contains a lipophilic compound of ethyl p-methoxycinnamate. Self-nanoemulsifying drug delivery system (SNEDDS) formulation can increase the solubility in water. The purpose this study was to determine effect surfactant combination on kencur SNEDDS system. formulations were carried out by selecting ratio Tween 80:Span 80 and 80:Chremophor R...
