INCI: Trioctyldodecyl Citrate

A gentle, non-greasy emollient that helps skin feel soft and smooth without clogging pores.

In plain English

Trioctyldodecyl Citrate is a synthetic ingredient made from citric acid (found in citrus fruits) and a type of fatty alcohol. In skincare, it works as an emollient, meaning it fills in the tiny gaps between skin cells to create a smoother, softer surface. It feels lightweight and non-greasy, making it a popular choice for moisturizers, sunscreens, and makeup products. Because it has a low risk of irritation and is unlikely to clog pores, it is often used in formulations for sensitive or acne-prone skin.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic ester created by combining citric acid with trioctyldodecyl alcohol. It is a clear, oily liquid that mimics the feel of natural skin oils.

How it works

It sits on the surface of the skin, forming a thin, breathable film that reduces water loss and improves skin texture. It also helps other ingredients spread evenly and gives products a silky, luxurious feel.

Pros

Lightweight feel

Unlike heavier oils, Trioctyldodecyl Citrate absorbs quickly and leaves no sticky residue, making it ideal for daytime use and under makeup.

Low irritation potential

It is considered very gentle on the skin, with a low risk of causing redness or breakouts, even for those with reactive skin types.

Cons and cautions

Not a humectant

This ingredient softens skin but does not actively draw water into the skin, so it works best paired with hydrating ingredients like glycerin or hyaluronic acid.

Synthetic origin

It is manufactured in a lab, which may be a drawback for consumers seeking 100% natural or plant-derived skincare options.

Best for

  • People with oily or combination skin who want moisture without greasiness
  • Those with sensitive or acne-prone skin looking for a gentle emollient

Use caution if

  • Individuals who strictly avoid synthetic ingredients in their skincare

Usage tips

Use products containing this ingredient as part of your moisturizing step after water-based serums.
Layer with a humectant serum (like one with hyaluronic acid) for balanced hydration.
