Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging C12-14 Isoparaffin.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
C12-14 Isoparaffin is a mixture of hydrocarbon molecules with 12 to 14 carbon atoms, derived from petroleum refining. It is a clear, colorless liquid with a low viscosity and high volatility, meaning it evaporates rapidly at skin temperature.
How it works
In a cosmetic product, C12-14 Isoparaffin acts as a solvent to dissolve oil-based ingredients and as a spreading agent to help the product glide over skin. Its quick evaporation leaves a non-greasy, dry feel, making it ideal for lightweight textures like micellar waters and gel cleansers.
Pros
Lightweight feel
Evaporates quickly, leaving skin feeling clean and not greasy—great for oily skin types.
Effective solvent
Helps dissolve stubborn makeup and sunscreen without heavy rubbing, reducing irritation.
Cons and cautions
Petroleum-derived
Sourced from non-renewable petroleum, which may be a concern for eco-conscious consumers.
Potential dryness
In high concentrations or on already dry skin, the rapid evaporation can strip natural oils, leading to tightness.
Best for
- People with oily or combination skin who prefer lightweight textures
- Anyone using makeup removers or cleansers that need to dissolve waterproof makeup
Use caution if
- Those with very dry or compromised skin barriers who may find it slightly drying
- Individuals seeking exclusively natural or plant-based ingredients
Usage tips
Safety summary
C12-14 Isoparaffin is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential, but may cause dryness in sensitive or dry skin types. Avoid inhalation of aerosolized forms.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) and other bodies have concluded that isoparaffins are safe in cosmetics. Studies focus on skin irritation and sensitization, with no significant concerns at standard use levels.
Common label clues
- Typical concentration
- 1-10% in rinse-off products; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US (FDA), and other major markets. The Cosmetic Ingredient Review (CIR) panel has deemed isoparaffins safe as used in cosmetics.
- Common uses
- Makeup removers, Facial cleansers, Moisturizers, Sunscreens
- Environmental note
- As a petroleum derivative, its production has a higher carbon footprint compared to plant-based alternatives. It is not biodegradable in the environment.
Good to know
- Often appears alongside other isoparaffins (e.g., C13-14 Isoparaffin) for tailored evaporation rates.
- Common in micellar waters and oil-free makeup removers.
- Considered safe by major regulatory bodies when used within standard cosmetic concentrations.
