• Charakteristisch

  Tween 80, commercially known as Polysorbate-80, is a viscous, water-soluble Yellow to amber liquid derived from polyethoxylated sorbitan and oleic acid. Tween 80 is structurally similar to the (polyethylene) glycols and used both in injections (0.8-8.0%) and in oral suspension (0.375% w/v). A number of anticancer drugs can be formulated by Tween 80. Typical examples include etoposide and minor groove-binding cyclopropylpyrroloindole analogues like carzelesin.

• Chemische Eigenschaften

  Tween 80 has a faint, characteristic odor and a warm, somewhat bitter taste. It is a mixture of oleate partial esters of sorbitol and sorbitol anhydrides condensed with approximately 20 mole of ethylene oxide (C2H4O) for each mole of sorbitol and its mono- and dianhydrides.

• Verwenden

  Tween 80 is a general purpose mid-range HLB, ethoxylated, nonionic surfactant suggested for use in textile chemicals (emulsifier, lubricant), household products and cosmetic formulations (o/w emulsifier, viscosity modifier).

• Verwenden

  Tween 80 is used as an antistat for PVC and as an antifog for PP, PE, PVC, PS.

• Verwenden

  Tween 80 is used as an emulsifier (ice cream, whipped topping) and as a solubilizing and dispersing agent in pickles and special vitamin-mineral preparations.

• Verwenden

  Tween 80 is the trade name of a detergent that can be useful in identifying mycobacteria that possess a lipase that splits the compound into oleic acid and polyoxyethylated sorbitol.
  Tween 80 is used as an additive for cell culture media. It has numerous effects, e.g. increasing the transformation frequency of Brevibacterium lactofermentum or enhancing the secretion of acid and alkaline phosphatase by Neurospora crassa.

• Definition

  ChEBI: A polymer composed of PEG-ylated sorbitan, where the total number of poly(ethylene glycol) units is 20 (w + x + y + z = 20) and a single terminal is capped by an oleoyl group.

• Trademarks

  Sorlate (Abbott); Tween 80 (ICI Americas).

• Allgemeine Beschreibung

  Amber-colored viscous liquid. pH (5% aqueous solution) 5-7. Faint odor and bitter taste.
  Polysorbate 80 (Tween 80) is a synthetic surfactant composed of fatty acid esters of polyoxyethylene sorbitan. Polysorbate 80 is usually available as a chemically diverse mixture of different fatty acid esters, with the oleic acid comprising>58% of the mix. However, the main component of polysorbate 80 is polyoxyethylene-20-sorbitan monooleate, which is structurally similar to polyethylene glycols. Polysorbate 80 has a molecular weight of 1309.7 Da and a 1.064 g/ml density[1].

• Air & Water Reaktionen

  Water soluble.

• Reaktivität anzeigen

  Tween 80 is incompatible with strong alkalis and oxidizers.

• Brandgefahr

  Tween 80 is probably combustible.

• Biochem/physiol Actions

  Tween 80 is used as emulsifiers, dissolving agents and stabilizer for essential oils, topical application and medical infusions including intravenous, subcutaneous or intramuscular administration.

• Pharmakokinetik

  Polysorbate 80 (Tween 80) is rapidly removed from systemic circulation. The polysorbate 80 plasma concentration-time curve (AUC) in a patient administered an intravenous (IV) infusion of docetaxel 35 mg/m2 (polysorbate 80 1.75 g) showed a polysorbate 80 peak concentration of 304 μg/ml. The AUC for polysorbate 80 was 321.7 mg h/ml, with a short disposition half-life of 1.07 h and a total plasma clearance of 5.44 l/h. The distribution of polysorbate 80 at steady state was similar to the total blood volume (4.16 l), suggesting that polysorbate 80 circulates as large micelles and does not significantly distribute outside the central compartment. In vitro studies suggest that polysorbate 80 is metabolized by rapid carboxylesterase-mediated hydrolysis[1].

• Sicherheitsprofil

  Moderately toxic by intravenous route. Mildly toxic by ingestion. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data. Human mutation data reported. An eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
