PEG-40 Stearate is a nonionic emulsifier and surfactant made from stearic acid.
It's water-soluble and good at coaxing oil + water to mix to keep everything stable.
The CIR Expert Panel has repeatedly concluded this ingredient to be safe at current cosmetic use levels with minimal skin/eye irritation when tested at 100%.
Your skincare also won't be containing 100% of this ingredient: the supplier recommends using 1-5% in a formula.
Broader reviews back this up: PEGs and their fatty-acid esters produce little or no skin/eye irritation, don't readily penetract intact skin, and rarely cause sensitization.
Because this ingredient is a PEG ester of stearic acid, it may not be fungal acne, or Malassezia, safe. Stearic acid (C18) sits in the C11-24 "edible window" that Malassezia lipases can cleave and metabolize.
