Dicaprylyl Ether
INCI: Dicaprylyl Ether
A gentle, fast-absorbing emollient that softens skin without clogging pores or leaving a heavy residue.
In plain English
Dicaprylyl Ether is an oil-like ingredient made from natural sources like coconut or palm oil. Unlike heavy oils, it spreads easily and absorbs quickly, leaving skin feeling smooth and soft without a greasy film. It's often used in lightweight moisturizers, sunscreens, and makeup removers to improve texture and help other ingredients glide on.

Quick decision guide
Easy yes for most routines
Dicaprylyl Ether 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 Dicaprylyl Ether.
- 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
Dicaprylyl Ether is a clear, odorless liquid derived from caprylic alcohol, which comes from coconut or palm kernel oil. Chemically, it's an ether—a type of compound known for its stability and lightweight feel. In cosmetics, it acts as an emollient, solvent, and skin conditioning agent.
How it works
When applied to the skin, Dicaprylyl Ether forms a thin, breathable layer that reduces water loss (transepidermal water loss, or TEWL) and helps maintain hydration. Its low viscosity allows it to spread quickly, making products feel silky and non-sticky. It also helps dissolve other ingredients, like sunscreen filters or active oils, ensuring even application.
Pros
Lightweight and fast-absorbing
Dicaprylyl Ether absorbs quickly without leaving a greasy residue, making it ideal for daytime moisturizers and sunscreens.
Low risk of clogging pores
With a low comedogenic rating, it's unlikely to cause breakouts, even for acne-prone skin types.
Cons and cautions
Sustainability concerns
Often derived from palm or coconut oil, its production can contribute to deforestation if not sourced responsibly.
Limited deep hydration
While it softens skin, it doesn't provide the intense moisture that heavier oils or butters offer for very dry skin.
Best for
- People with oily or combination skin who want lightweight moisture
- Anyone looking for a non-greasy makeup remover or sunscreen base
Use caution if
- Those with extremely dry skin may prefer richer emollients like shea butter or jojoba oil
Usage tips
Safety summary
Dicaprylyl Ether is considered safe for topical use in cosmetics. It has low irritation and sensitization potential, and no known toxicity at typical concentrations. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used.
Research notes
Studies confirm Dicaprylyl Ether is a well-tolerated emollient with good skin compatibility. It is frequently cited in formulation science for its sensory benefits and low irritation profile. Peer-reviewed research supports its use as a non-comedogenic alternative to heavier oils.
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.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup removers, Hair conditioners
- Environmental note
- Derived from renewable plant sources, but sustainability depends on farming practices. Look for RSPO-certified palm or organic coconut sources.
Good to know
