Tween 60

Tween 60 is a nonionic surfactant commonly used in biochemical and cell culture applications.
It is a polyoxyethylene sorbitan monostearate, with a hydrophile-lipophile balance (HLB) value of 14.9, making it suitable for emulsifying and solubilizing a wide range of compounds.
Tween 60 is known for its low toxicity and is often employed to enhance the solubility and stability of proteins, enzymes, and other biomolecules.
Its mild detergent properties make it useful in cell lysis, immunoassays, and other laboratory procedures that require the dispersion or extraction of cellular components.
Tween 60 is also used in the formulation of pharmaceuticals, cosmetics, and personal care products to improve the solubility and dispersion of active ingredients.

Design of Experiments 10.0.3 software (Stat-Ease Inc., Minneapolis, MN, USA) applying the Box-Behnken methodology was used to investigate the effect of self-governing variables (hydration time, hydration volume, and the cholesterol content; Table 1) on physicochemical features of E. angustifolia-loaded niosomes. Table 2 shows these factors, their degree, as well as their impacts on the nanoparticle size and entrapment efficiency (EE). The minimal size of the niosomes and the maximal entrapment efficiency were taken as the optimization criteria based on the multi-criteria optimization used [15 (link)]. The data optimization of the D-optimal study was performed based on the desirability index [16 (link)]. Furthermore, the discrepancies of the anticipated and the perceived results were computed, and the optimized formation was then discerned for more far-away studies [17 (link),18 (link),19 (link)].
The thin-layer hydration method described in our prior research with slight changes was used to prepare the E. angustifolia-loaded niosomes [20 (link)]. Briefly, Span 60, Tween 60, and cholesterol were suspended in an organic solvent (2:1 of chloroform:methanol (v/v), 10 mL), accompanied by evaporation of solvents using a rotary evaporator (150 rpm, 60 °C, 30 min). Subsequently, thin layers were hydrated, and 15 mg of the drug (concentration of 1.5 mg mL−1) with different hydration volumes and time (Table 1 and Table 2) was added at 60 °C and 120 rpm. Lastly, 7 min of sonication was performed to obtain the uniform size distribution of E. angustifolia-loaded niosomes. The specimens were refrigerated (4 °C) for further experimental research. The compositions of niosomal formation are listed in Table 2.

We used the thin-film hydration method to prepare the curcumin and paclitaxel-loaded niosomes [47 (link)]. Tween-60 (DaeJung Chemicals & Metals, South Korea) and cholesterol (Sigma-Aldrich, USA) were dissolved in chloroform to obtain the different molar ratio molarities (as illustrated in Table 1). PTX (Stragen, Switzerland) and CUR (Sigma-Aldrich, USA) were dissolved in chloroform and added to the mixture of surfactant and lipids. Fluorescent label Dil (Sigma, USA) was added to the lipid phase at 0.1% mol for lipid staining to evaluate cellular uptake. Niosomal formulations were screened for particle size, controlled release, and high entrapment efficiency parameters. After attaining optimized synthetic conditions, the cationic lipid DOTAP (1,2-dioleoyl-3-trimethylammonium-propane, Sigma-Aldrich, USA) and polyethylene glycol (Lipoid PE 18:0/18:0–PEG2000, DSPE-mPEG 2000, Lipoid GmbH, Germany) were added for improving stability and transfection efficiency of the niosomal formulations. Organic solvent was removed by rotary evaporator (Heidolph, Germany) at 50 °C until a thin-layered film formed. The dry lipid films were hydrated by adding phosphate-buffered saline (PBS, pH = 7.4) at 60 °C for 60 min to obtain the niosomal suspensions. After hydration, the prepared vesicles were sonicated for 30 min using a microtip probe sonicator (model UP200St, Hielscher Ultrasonics GmbH, Germany) to reduce the vesicles’ mean size. Thereafter, free drugs (unloaded) were separated from niosomal vesicles using a dialysis bag diffusion technique against PBS for 1 h at 4 °C (MW = 12 kDa, Sigma-Aldrich, USA) [48 (link)]. Drug-free niosomes were produced in a similar manner without adding curcumin and paclitaxel. The dose of both drugs was 0.5 mg mL−1 for all formulations.

Based on previous work of our research team (data under publication), two spanlastic formulae (F1 and F2) were chosen as a foundation for the preparation of PECSs formulae. They contained Span® 60 along with Tween® 80 as an edge activator (EA). F1: 400 mg Span® 60 and 100 mg of Tween® 80 (4:1 weight ratio) and F2: 300 mg of Span® 60 and 200 mg of Tween® 80 (3:2 weight ratio). Each formula had 25 mg of Hal and the total volume was 10 ml. These were prepared using ethanol injection method as described by Kakkar & Kaur (2011 (link)). Briefly, Hal and Span® 60 were dissolved in 2 ml ethanol and injected dropwise into a hot (60 °C) Tween® 80 solution. The resulting hydroalcoholic solution was continuously stirred on a magnetic stirrer (Model MSH-20 D; Witeg Labortechnik GmbH Germany) for 30 minutes at 800 rpm to completely evaporate any remaining ethanol and to form Hal-loaded aqueous spanlastic dispersions. Ultrasonic water-bath sonication (Crest ultrasonics Corp., Trenton, NJ, USA) was done for 5 min to obtain a suitable particle size. These formulae were prepared again, but with the incorporation of one of three penetration enhancers (PE): Labrasol®, Transcutol® P or Tetraglycol® (Ahad et al., 2009 (link); Mura et al., 2009 (link)). These were used at 1% w/v concentration (100 mg) (Sinha & Kaur, 2000 (link)) in the final dispersion and were dispersed in the edge activator (EA) solution during preparation. Thus, six PECS formulae were obtained.
