Ingredient review
Hydrogenated Poly(C6-14 Olefin)
INCI: Hydrogenated Poly(C6-14 Olefin)
A silky, non-greasy synthetic emollient that mimics the feel of natural oils without clogging pores.
In plain English
This is a man-made oil that feels light and smooth on your skin, similar to natural oils but without the greasiness. It helps your moisturizer or serum spread easily and leaves a soft, velvety finish. Because it's made in a lab, it's very stable and doesn't go rancid like plant oils can.

Quick decision guide
Easy yes for most routines
Hydrogenated Poly(C6-14 Olefin) is generally a lower-concern ingredient when the full formula suits your skin.
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 Hydrogenated Poly(C6-14 Olefin).
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 synthetic hydrocarbon oil created by polymerizing and then hydrogenating medium-chain olefins (C6-14). The result is a clear, odorless, and very stable liquid that acts as a lightweight emollient.
How it works
It sits on the surface of the skin, filling in tiny gaps between skin cells to create a smooth, even texture. This reduces water loss (transepidermal water loss, or TEWL) by forming a protective film, while its low viscosity allows it to spread thinly without feeling heavy or sticky.
Pros
Lightweight and non-greasy
Unlike many natural oils, this ingredient absorbs quickly and leaves a velvety finish, making it ideal for oily or acne-prone skin types.
Excellent stability
Because it's fully hydrogenated, it resists oxidation and won't go rancid, so products stay effective longer without needing preservatives.
Cons and cautions
Synthetic origin
It is derived from petrochemicals, which may be a concern for those seeking plant-based or naturally derived ingredients.
Limited skin absorption data
While generally considered safe, there is less published research on how much of this ingredient penetrates the skin compared to more traditional emollients.
Best for
- People with oily or combination skin who want hydration without greasiness
- Anyone looking for a stable, non-irritating emollient in their daily moisturizer
Use caution if
- Those who strictly avoid synthetic ingredients in their skincare routine
Usage tips
Safety summary
Hydrogenated Poly(C6-14 Olefin) is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in regulatory reviews.
Research notes
Evidence is based on its chemical similarity to other safe hydrocarbon emollients and its long history of use in cosmetics. Direct clinical studies are limited, but regulatory bodies have deemed it safe.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics globally, including by the U.S. FDA and EU CosIng database, with no known restrictions at typical use levels.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup primers
- Environmental note
- As a synthetic hydrocarbon, it is not biodegradable and may persist in the environment. However, it is not classified as a microplastic due to its liquid form.
Good to know
- Hydrogenated Poly(C6-14 Olefin) is often used as a silicone alternative in 'silicone-free' formulations.
- It is considered non-comedogenic, meaning it is unlikely to clog pores.
