What does this ingredient do in an antiperspirant?
A diester of polyethylene glycol and stearic acid: two acid residues are attached to the PEG chain. CosIng lists emulsifying, cleansing and viscosity-controlling functions.
Part of a system, not a label in isolation
In the catalog it appears in roll-on emulsions, where it helps keep the mixture uniform and gives it the right thickness. It does not reduce sweating.
The CIR (2015) found PEG diesters, including PEG-150 Distearate, safe in cosmetics when formulated to be non-irritating. Most of its reported uses are in bath products, cleansers and shampoos.
The CIR cautioned that PEG diesters can enhance the skin penetration of other substances, which formulators take into account. Tolerance is determined by the finished product.
Do not confuse it with PEG-100 Stearate or Glyceryl Stearate: here two stearic acid residues, not one, are attached to the PEG.
