Beheneth-25 Methacrylate is a polymeric associative thickener and rheology modifier used in cosmetic formulations to control viscosity and stabilize emulsions. It functions as a structural base ingredient rather than an active skincare treatment.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation | Rare | Occasional transient redness or stinging, typically related to formulation as a whole rather than this ingredient alone. |
| Allergic contact dermatitis | Very rare | Isolated sensitization reports; uncommon for this class of polymeric thickeners. |
| Eye irritation | Rare | Possible upon direct contact with eyes in rinse-off or leave-on products. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
