Tween-80, Emulsifier T-80


Tween-80 is light yellow to amber oily viscose liquid, non-toxic. It is easily soluble in water, soluble in ethanol, vegetable oil, ethyl acetate, methanol, and insoluble in mineral oil. HLB value is 15.0.

The Tween-80 is a nonionic surfactant and emulsifier. This synthetic compound is a viscous, water-soluble yellow liquid.

Tween-80 is derived from polyethoxylated sorbitan and oleic acid. The hydrophilic groups in this compound are polyethers also known as polyoxyethylene groups, which are polymers of ethylene oxide. In the nomenclature of polysorbates, the numeric designation following polysorbate refers to the lipophilic group, in this case, the oleic acid.

Tween-80 is used as an emulsifier, wetting agent, penetrating agent, diffusant, etc.

Tween-80 is used as an emulsifier in foods.

For example, in ice cream, Tween-80 is added up to 0.5% (v/v) concentration to make the ice cream smoother and easier to handle, as well as increasing its resistance to melting. Adding this substance prevents milk proteins from completely coating the fat droplets. This allows them to join together in chains and nets, which hold air in the mixture, and provide a firmer texture that holds its shape as the ice cream melts.

This T-80 emulsifier is used as a wetting agent in flavored mouth drops such as Ice Drops, helping to provide a spreading feeling to other ingredients like SD alcohol and mint flavor.

The World Health Organization has suggested acceptable daily intake limits of 0–25 mg of polyoxyethylene sorbitan esters per kg body weight.

Tween-80 is also used as a surfactant in soaps and cosmetics (including eyedrops), or a solubilizer such as in a mouthwash. The cosmetic grade of polysorbate 80 may have more impurities than the food grade.

T-80 emulsifier is an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the popular antiarrhythmic amiodarone. It is also used as an excipient in some European and Canadian influenza vaccines. Influenza vaccines contain 2.5 μg of Tween-80 per dose.

Packing and Storage:

In 200KGs iron drum/plastic drum.

Handle with care; Tween-80 should be stored in a cool, dry, and draughty place. The shelf life is 2 years. Then, Tween-80 can still be used if qualified after re-check.
