Laboratory analysis of polysorbate 20

You want to analyze the polysorbate 20 of your products?

Qu'est-ce que le polysorbate 20 (n° CAS 9005-64-5) ?

Polysorbate 20, also known as tween 20 or E432, is an additive made from sorbitol.  Acting as a texturizing agent, polysorbate 20 is also a stabilizer, a synthetic thickener and an emulsifier. As a lemon-yellow oily liquid, polysorbate 20 is present in many everyday products.

In fact, polysorbate 20 is used in many products such as coconut milk, broths and soups, cookies and cakes, chocolates and ice creams. Polysorbate 20 is also present in animal feed as well as in pharmaceutical and cosmetic products.

In what context should a polysorbate 20 analysis be performed?

Recent studies suggest that polysorbate 20 may have adverse health consequences.

Indeed, the polysorbate 20 would be likely to contain harmful residues like ethylene oxide. The latter can cause skin reactions, digestive disorders or a poor assimilation of iron.

Moreover, this is why limit levels of polysorbate 20 have been set according to the nature of the finished product. For example, a maximum concentration of 1% (v/v) of polysorbate 20 is fixed in pharmaceutical products.
