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
A mixture of hydrocarbon chains (13 to 14 carbons long) produced through petroleum refining. It is a clear, odorless liquid that acts as a solvent and emollient.
How it works
It sits on the skin's surface to soften and smooth it, while also helping to dissolve other ingredients like sunscreen filters or makeup. Its low viscosity allows products to spread easily and absorb quickly without leaving a sticky residue.
Pros
Lightweight feel
Evaporates quickly, leaving skin soft without a heavy or sticky layer.
Improves product texture
Helps creams and lotions spread smoothly and evenly, enhancing the user experience.
Cons and cautions
Petroleum-derived
Sourced from crude oil, which may not align with natural or eco-conscious preferences.
Potential dryness
In high concentrations without complementary moisturizers, it can slightly dry out very dry skin due to its evaporative nature.
Best for
- People with oily or combination skin who prefer lightweight textures
- Anyone looking for a non-greasy makeup remover or sunscreen
Use caution if
- Those who prefer exclusively plant-based or natural ingredients
- Individuals with very dry or dehydrated skin if the product lacks additional moisturizers
