Ingredient review
Isooctyl Tallate
INCI: ISOOCTYL TALLATE
A lightweight, non-greasy emollient that helps soften skin and improve product texture, generally well-tolerated.
In plain English
Isooctyl tallate is a synthetic emollient made from tall oil (a byproduct of wood pulp processing) and isooctyl alcohol. It spreads easily on skin, feels lightweight, and helps other ingredients absorb better. Think of it as a silky, non-sticky oil that makes lotions feel smooth without leaving a heavy residue.

Quick decision guide
Useful, but context matters
Isooctyl Tallate 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 Isooctyl Tallate.
- 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
An ester formed by combining isooctyl alcohol with fatty acids from tall oil, a natural byproduct of pine tree wood processing. It is a clear, oily liquid used in cosmetics to improve skin feel and texture.
How it works
It sits on the skin's surface, filling in gaps between skin cells to create a smooth, soft feel. It also reduces water loss by forming a thin barrier, which helps keep skin hydrated. Its lightweight nature allows it to be absorbed quickly without clogging pores.
Pros
Lightweight texture
Unlike heavier oils, isooctyl tallate absorbs quickly and leaves skin feeling soft without a sticky or greasy residue.
Good for sensitive skin
It has a low irritation and comedogenic risk, making it suitable for most skin types, including those prone to breakouts.
Cons and cautions
Wood-derived source
It comes from tall oil, a byproduct of wood pulp processing, which may not appeal to those avoiding synthetic or industrial byproducts.
Limited research
While generally considered safe, there are fewer studies on isooctyl tallate compared to more common emollients like jojoba oil or squalane.
Best for
- People with normal to dry skin seeking lightweight moisture
- Those who prefer non-greasy lotions and creams
Use caution if
- Individuals with known allergies to pine or wood-derived ingredients
- Those seeking 100% plant-based or vegan formulations (tall oil is a byproduct of paper industry)
Usage tips
Safety summary
Isooctyl tallate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. However, individuals with allergies to pine or wood-derived ingredients should patch test first.
Research notes
Research on isooctyl tallate specifically is limited, but it is structurally similar to other fatty acid esters that are well-studied and considered safe. The Cosmetic Ingredient Review (CIR) has reviewed related esters and found them safe for cosmetic use.
Common label clues
- Typical concentration
- 1% to 10% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar esters and found them safe at typical concentrations.
- Common uses
- Moisturizers, Body lotions, Facial creams, Sunscreens, Makeup removers
- Environmental note
- Tall oil is a renewable byproduct of the paper industry, but its processing involves chemical synthesis, which may have environmental impacts.
Good to know
- Isooctyl tallate is often used in sunscreens to improve texture and water resistance.
- It is not the same as tallow (animal fat); tall oil is plant-derived.
