Sorbitan Isostearate
May feed Fungal Acne
Non-fungal acne-safe products contain ingredients that can worsen fungal acne. If you suspect fungal acne, consult a dermatologist for proper diagnosis.
Explained
Sorbitan Isostearate is an emulsifer. It is created from isostearic acid and sorbitol.
As an emulsifier, it keeps the water and oil ingredients from separating. This keeps formulas stable and smooth.
In a 24 hour occlusive patch test on 56 subjects, 10% sorbitan isostearate was completely non-irritating. Most formulas use less than 10%.
Because it's a fatty acid ester, it may not be fungal acne safe since the Malassezia yeast can utilize it as a nutrient source.
