In our reference data, Polyglyceryl-4 Isostearate can feed Malassezia (fungal acne).
Polyglyceryl-4 Isostearate is a polyglycerol ester of isostearic acid used as a non-ionic emulsifier and surfactant, primarily to stabilize water-in-oil emulsions and improve texture in creams, cleansers, and makeup. It is considered a mild, plant-derived alternative to PEG-based emulsifiers.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Rare | Generally well tolerated; occasional irritation reported mainly with high concentrations or compromised skin barrier. |
| Allergic contact dermatitis | Very rare | Isolated sensitization cases reported; polyglyceryl esters have low allergenic potential. |
| Eye irritation | Rare | Possible transient stinging if formulations contact the eyes, as with most surfactants. |
