C15-23 Alkane is a blend of medium-to-long-chain saturated hydrocarbons, often plant-derived, used as a lightweight, non-greasy emollient and silicone alternative. It softens skin and improves spreadability and texture in formulations.
| Reported effect | How often | Notes |
|---|---|---|
Mild irritation or stinging | Rare | Generally well tolerated; transient irritation possible in sensitive skin. |
Contact dermatitis or allergic reaction | Very rare | Allergenic potential is considered very low for inert alkanes. |
Comedogenicity (clogged pores) | Rare | Low comedogenic risk, but heavy occlusion may affect acne-prone skin. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
