Isododecane is a lightweight, volatile branched-chain hydrocarbon used as a solvent and emollient in cosmetics. It spreads easily and evaporates quickly, improving texture and wear in products like long-lasting makeup, primers, and sunscreens.

Skin dryness | Uncommon | Its volatility can contribute to a dry or tight feeling on the skin with frequent use. |
Irritation | Rare | Mild irritation or stinging may occur, particularly on sensitive or compromised skin. |
Allergic contact dermatitis | Very rare | Sensitization is uncommon as it is generally considered non-sensitizing. |
Eye irritation | Rare | Can cause transient stinging if it migrates into the eyes in eye-area products. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
