Laboratory analysis of polysorbate 80

You want to realise the analysis of polysorbate 80 of your products?

What is polysorbate 80 (CAS n° 9005-65-6)

Polysorbate 80, also known as tween 80 or E433, is an additive made from sorbitol.  Acting as a texturing agent, polysorbate 80 is also a stabilizer, a synthetic thickener and an emulsifier. As a lemon-yellow oily liquid, polysorbate 80 is present in many everyday products.

In fact, polysorbate 80 is used in several products including coconut milk, broths and soups, cookies and cakes, chocolates and ice creams. Polysorbate 80 is also present in animal feed as well as in pharmaceutical and cosmetic products.

Why analyze polysorbate 80?

Recently conducted studies suggest that polysorbate 80 would have harmful consequences on health.

Indeed, polysorbate 80 would be likely to increase the intestinal permeability by disturbing the bacteria of the intestinal flora. It would also favour chronic inflammatory pathologies of the intestine. Moreover, polysorbate 80 is also implicated in metabolic syndrome and the development of diabetes.

Moreover, this is why limit levels of polysorbate 80 have been set according to the nature of the finished product. Indeed, polysorbate 80 is authorized in France under the condition of respecting an ADI (Acceptable Daily Dose) fixed at 25 mg/kg/day.
