Ingredient review
Isosorbide Dicaprylate/Caprate
INCI: ISOSORBIDE DICAPRYLATE/CAPRATE
A gentle, non-greasy emollient derived from plant sources that softens skin and improves product texture.
In plain English
Isosorbide Dicaprylate/Caprate is a skin-friendly ingredient made from isosorbide (a plant-derived compound) and fatty acids from coconut or palm oil. It works as an emollient, meaning it fills the spaces between skin cells to smooth and soften the skin's surface. Unlike some heavier oils, it feels light and silky, absorbs quickly, and leaves no sticky or greasy residue. It's often used in moisturizers and sunscreens to improve spreadability and give a pleasant, non-oily feel.

Quick decision guide
Easy yes for most routines
Isosorbide Dicaprylate/Caprate 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 Isosorbide Dicaprylate/Caprate.
- 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 created by combining isosorbide (derived from sorbitol, a sugar alcohol from corn or other plants) with caprylic and capric fatty acids (typically from coconut or palm oil). It is a clear, low-viscosity liquid that functions as an emollient and skin conditioning agent.
How it works
When applied to the skin, it forms a thin, breathable film that helps reduce water loss (transepidermal water loss, or TEWL) by temporarily sealing moisture in. It also smooths rough patches by filling in gaps between dead skin cells, making the skin feel softer and more supple. In formulations, it reduces the greasy feel of other oils and helps active ingredients spread evenly.
Pros
Lightweight feel
Unlike heavy oils, this ingredient absorbs quickly and leaves skin feeling silky, not greasy, making it ideal for daytime use.
Low irritation potential
Clinical and safety data indicate it is very gentle on skin, with low risk of irritation or clogged pores, suitable for sensitive and acne-prone skin types.
Cons and cautions
Sustainability concerns
The fatty acids are often sourced from palm oil, which can be linked to deforestation if not certified sustainable. Look for RSPO-certified versions.
Limited research
While safe and effective as an emollient, there is less published research on its long-term skin benefits compared to more studied ingredients like squalane or glycerin.
Best for
- People with oily or combination skin who want hydration without shine
- Those with sensitive skin looking for a gentle, low-irritation emollient
Use caution if
- Individuals with a known allergy to coconut or palm oil derivatives (rare)
Usage tips
Safety summary
Isosorbide Dicaprylate/Caprate is considered safe for cosmetic use with low irritation and comedogenic potential. It is well-tolerated by most skin types, including sensitive skin. No significant safety concerns have been reported in regulatory or clinical reviews.
Research notes
Research supports its function as a lightweight emollient that improves skin feel and formulation aesthetics. Safety assessments by the Cosmetic Ingredient Review (CIR) and EU CosIng confirm its safety at typical use concentrations. More studies on its long-term skin barrier benefits would be valuable.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA as a skin conditioning agent. No known restrictions.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup removers
- Environmental note
- The ingredient is biodegradable, but its environmental footprint depends on the sourcing of palm oil. Opt for products with RSPO-certified palm derivatives when possible.
Good to know
- Isosorbide Dicaprylate/Caprate is often used as a replacement for silicones in 'silicone-free' formulations.
- It is biodegradable and considered environmentally friendlier than some petroleum-based emollients.
