What is Sorbitan Stearate?
Chemically, Sorbitan Stearate is an emulsifier that helps oil and water mix. A mild sorbitan-based emulsifier that is low-risk for comedogenicity, but a fatty-acid ester that fungal-acne routines commonly avoid.
Where Sorbitan Stearate shows up
Sorbitan Stearate is commonly formulated into almost any lotion or cream, where it keeps the oil and water phases blended. Separately from clogging, its irritancy is rated 0/5 — low, so it's unlikely to sting or sensitise on its own.
Is Sorbitan Stearate bad for acne-prone skin?
That low score makes Sorbitan Stearate a reasonable choice even for acne-prone skin. As always, individual reactions vary, but it is not a likely cause of clogged pores.
Note for fungal-acne (malassezia) sufferers: Sorbitan Stearate is commonly avoided in fungal-acne routines, since it falls into the fatty-acid or ester families the yeast can feed on. The evidence there is looser than for comedogenicity — see our fungal-acne checker for context.
