Polysorbate 20 is used by philatelists to remove stamps from envelopes and to remove residues from stamps, without harming the stamp itself. Polysorbate 20 is also used as wetting agent in rubber balers in the elastomer industry. Polysorbate 20 has been used as a shape directing agent to synthesize spheroidal magnetite nanoassemblies. [5]
Polysorbate 20 is also known as Tween 20, a commercial brand name. It is a common detergent used in many buffers for washing nitrocellulose membrane in western blotting and microtiter plate wells in ELISA assays. Tris is a buffer that maintains a pH of 7–9.2.
Polysorbate 20, a compound used as a food additive in some pudding mixes to prevent scorching during preparation. Polysorbates are a class of emulsifiers used in some pharmaceuticals and food preparation. They are commonly used in oral and topical pharmaceutical dosage forms.
Polysorbate 20 – emulsifier; Polysorbate 40 – emulsifier; Polysorbate 60 – emulsifier; Polysorbate 65 – emulsifier; Polysorbate 80 – emulsifier; Polyvinylpolypyrrolidone – color stabiliser; Pomegranate seeds (though some consider these a fruit, not a spice) – Ponceau 4R – color (FDA: Ext D&C Red #8) Ponceau 6R – color; Ponceau ...
Another type of lipid-nanoparticle that can be used for drug delivery to the brain is a cationic liposome. These are lipid molecules that are positively charged. [6] One example of cationic liposomes uses bolaamphiphiles, which contain hydrophilic groups surrounding a hydrophobic chain to strengthen the boundary of the nano-vesicle containing ...
Sorbitan is produced by the dehydration of sorbitol and is an intermediate in the conversion of sorbitol to isosorbide.The dehydration reaction usually produces sorbitan as a mixture of five- and six-membered cyclic ethers (1,4-anhydrosorbitol, 1,5-anhydrosorbitol and 1,4,3,6-dianhydrosorbitol) [3] with the five-membered 1,4-anhydrosorbitol form being the dominant product.
Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products.. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone.

IGEPAL CA-630 has HLB of 13.4, similar to that of Triton X-100 (13.4) and thus belongs to the detergent range (HLB 13-15); this is significantly less than 17.8 of tergitol NP-40 or 16.7 of Polysorbate 20 (also known as Tween 20), which both belong in the solubilizer range (15-18) of HLB. [2] Ca-630 is completely miscible with water.
