Octyldodecyl Behenate
INCI: OCTYLDODECYL BEHENATE
A gentle, non-greasy emollient that softens skin and improves product texture without clogging pores.
In plain English
Octyldodecyl behenate is a synthetic oil-like ingredient made from behenic acid (a fatty acid from oils like rapeseed) and a branched alcohol. It spreads easily on skin, leaving a smooth, silky finish without feeling heavy or sticky. It also helps other ingredients mix together and stay stable in products like creams and sunscreens.

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
An ester formed by combining behenic acid (a long-chain fatty acid found in some plant oils) with octyldodecanol (a branched-chain alcohol). It is a clear, odorless liquid at room temperature.
How it works
It sits on the skin's surface, forming a thin, breathable film that reduces water loss and makes the skin feel soft and smooth. Its molecular structure allows it to spread evenly, improving the texture and application of cosmetic products.
Pros
Silky texture
Leaves skin feeling smooth and soft without a greasy residue, making it ideal for daytime moisturizers and sunscreens.
Low irritation potential
Rated as low-irritation and low-comedogenic, it is generally safe for sensitive and acne-prone skin types.
Cons and cautions
Synthetic origin
As a lab-made ingredient, it may not fit into 'natural' or 'clean' beauty routines preferred by some consumers.
Limited research
While safety data is positive, there are fewer long-term studies compared to more common emollients like shea butter or squalane.
Best for
- People with normal to dry skin looking for lightweight moisture
- Anyone who prefers non-greasy, fast-absorbing products
Use caution if
- Those strictly avoiding synthetic ingredients
