In our reference data, C25-52 Olefin/Undecylenic Acid Copolymer can feed Malassezia (fungal acne).
C25-52 Olefin/Undecylenic Acid Copolymer is a synthetic copolymer used primarily as a film-forming and texturizing agent in cosmetic and skincare formulations, helping to improve spreadability, sebum control, and the wear of the finished product. It functions as a base/formulation ingredient rather than as a biologically active treatment.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | Occasional transient redness or irritation reported, generally in sensitive skin. |
Contact allergic reaction | Very rare | Isolated sensitization reports; polymer is considered low risk for allergy. |
Follicular occlusion / comedogenicity | Very rare | Film-forming polymers may theoretically contribute to pore occlusion in acne-prone users, though data are limited. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
