Isostearic Acid
May cause Acne
These ingredients are known to potentially trigger breakouts, but they won’t cause acne for everyone. Everyone’s skin responds differently so what clogs pores or causes breakouts for one person might be perfectly fine for another.
May feed Fungal Acne
These ingredients are considered potential triggers for fungal acne, but not everyone will react to them. Because fungal acne can be tricky to identify and manage, it’s best to consult a dermatologist for an accurate diagnosis and treatment plan.
Explained
Isostearic acid is a saturated fatty acid. Its structure makes it a great surfactant.
Surfactants help decrease the surface tension between two liquids. This property also makes it an effective emulsifier. Emulsifiers help prevent waters and oils from separating in a product.
Isostearic Acid is created from oleic acid.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
