Ingredient review
Hydrogenated Olive Oil Caprylyl Esters
INCI: Hydrogenated Olive Oil Caprylyl Esters
A gentle, plant-derived emollient that hydrates and softens skin without clogging pores, ideal for sensitive and dry skin types.
In plain English
This ingredient is a modified version of olive oil that has been combined with a fatty acid from coconut or palm oil. The hydrogenation process makes it more stable and less greasy than regular olive oil, so it spreads easily and leaves skin feeling soft without a heavy residue. It works by forming a thin, breathable film on the skin that helps lock in moisture and smooth rough patches.

Quick decision guide
Easy yes for most routines
Hydrogenated Olive Oil Caprylyl Esters 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 Olive Oil Caprylyl Esters.
- 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 semi-synthetic ester made by reacting hydrogenated olive oil with caprylic acid (a fatty acid derived from coconut or palm oil). The result is a lightweight, non-greasy emollient that mimics the skin's natural oils.
How it works
Sits on the surface of the skin to reduce water loss (transepidermal water loss, or TEWL) and fills in gaps between skin cells, making the skin feel smoother and softer. It also helps other ingredients spread more evenly in a formula.
Pros
Lightweight hydration
Unlike pure olive oil, this ester is non-greasy and absorbs quickly, making it comfortable for daily use on the face and body.
Low irritation potential
Clinical and anecdotal evidence suggests it rarely causes stinging or redness, even on compromised skin barriers.
Cons and cautions
May not be rich enough for very dry skin
While it softens well, it is not as occlusive as heavier oils or butters, so very dry skin may need a thicker layer or a complementary occlusive.
Sustainability concerns with caprylic acid source
Caprylic acid is often derived from palm or coconut oil; unless certified sustainable, its production can have environmental impacts.
Best for
- People with dry or dehydrated skin looking for a gentle emollient
- Those with sensitive or reactive skin who want a low-irritation moisturizer
Use caution if
- Individuals with a known allergy to olive oil or caprylic acid (rare)
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Non-irritating and non-sensitizing in standard patch tests. No known toxicity or endocrine disruption concerns.
Research notes
Limited peer-reviewed studies specifically on this ester, but its components (hydrogenated olive oil and caprylic acid) are well-studied and recognized as safe by the Cosmetic Ingredient Review panel. Anecdotal evidence supports its gentle, moisturizing properties.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally (EU, US, Japan) with no known restrictions. It is not a drug ingredient.
- Common uses
- Moisturizers, Cleansers, Lip products, Body lotions
- Environmental note
- The olive oil component is typically a byproduct of olive processing, but the caprylic acid may come from palm oil. Look for products with RSPO-certified palm derivatives if sustainability is a concern.
Good to know
- This ingredient is often used as a lighter alternative to pure olive oil in 'clean' beauty formulations.
- It is stable and does not oxidize easily, so products containing it have a longer shelf life.
