The magnitude of CMC value of SLS was decreased in large amount in presence of MB due to the cationic and anionic (electrostatic) interaction, while a little bit decrement was obtained with tween 80 and no remarkable change was obtained with CTAB. Since, both the observed values with ...
(30 μg/lane) were separated on a sodium dodecyl sulfate polyacrylamide gel, then electrotransferred to polyvinylidene difluoride membranes. The blots were washed twice with Tris-buffered saline plus Tween (TBST; 20 mM Tris [pH 7.4], 0.9% NaCl, and 0.1% Tween-20), blocked with 5% bovine ...
This was determined by the surface tension of the industrial oleic acid, naphthenic acid and their mixtures at different temperatures CMC, visited Tween 80, polyethylene glycol, polyether and other non-ionic surfactant effects on the CMC of sodium oleate, was at the same concentration of Tween 80...
) be- tween the activity ofCMCasefrom Dictyophora strains for test and the growth rate of the hyphae, the weightlessness of the culture media, the cillulose loss of the media is presented. 本文主要报道供试竹荪菌株在不同基物上所产生的CMC酶活与菌丝生长速度,基物失重,基物纤维素损失量间的正...
(HLB值13~18, Tween20; poloxamer…) *增溶质---被增溶的物质。 *最大增溶浓度 MAC maximum additive concentration 当表面活性剂用量为1g时增溶药物达到饱和的浓度。 如: 1g Tween80 可增溶0.19g丁香油. 达到MAC后继续加入增溶质→溶液不再澄明。 一般...
The power-time curves of the micelle formation process were determined for the nonionic surfactant Tween80/nonaqueous solvent (DMF)/long-chain alcohol (n-heptanol, n-octanol, n-nonanol, and n-decanol) systems by titration microcalorimetry at temperatures of (298.15, 303.15, 308.15, and 313.15) ...
传统的表面活性剂有聚山梨醇酯(如Tween-80)、聚乙二醇蓖麻油(如Cremophor EL)等;新型的表面活性剂有:甘油酯44/14、聚乙二醇硬脂酸酯15(Solutol HS-15)。新型比传统表面活性剂,助溶效果、生物相容性及安全性更好,所以现在常用Solutol HS-15替代Tween-800。

The studied derivatives showed, in spite of moderate surface tension-lowering effects, excellent emulsifying activity for 'oil in water' type emulsions comparable to that of the commercial emulsifier Tween 20. The viscometric properties were investigated in the dilute domain. For all HM-CMC solutions...
