What does this ingredient do in an antiperspirant?
An ethoxylated ester of sorbitan and lauric acid (20 ethylene oxide units on average). INCI functions: emulsifying and cleansing surfactant; COSMILE also lists it as a functional excipient of perfume compositions.
Part of a system, not a label in isolation
In roll-ons and sprays it helps distribute oils and fragrance evenly in the water-based formula. It does not reduce sweating: aluminium or zirconium salts do that.
The CIR concluded that Polysorbate 20 is safe in the present practices of use (1984 assessment of polysorbates); the CIR summary table lists use concentrations above 50%.
It is used as an emulsifier; an individual reaction to the finished product is possible.
Not the same as Polysorbate 60: the fatty acid part of Polysorbate 20 is lauric acid, whereas in Polysorbate 60 it is stearic acid.
