An ethoxylated sorbitan monostearate, used as an emulsifier and cleansing agent.
What it is
Polysorbate 61 is a polyethylene glycol derivative of sorbitan monostearate, the ester of stearic acid with sorbitan, with an average of 4 ethylene oxide units. CosIng lists it as an emulsifying and cleansing surfactant.
Where it is used

Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
The number 4 is an average, so the raw material is a mixture of molecules of different sizes.
Functions
- Surfactant – emulsifying
- Helping suspensions or dispersions of liquids in a second liquid by reducing the surface tension of the substances to be emulsified.
- Surfactant – cleansing
- Wetting body surfaces, emulsifying or solubilizing oils, and suspending soil (generally, such ingredients contribute to the foaming and lathering properties of cleansing products).
