Kiwi Seed Oil Esters
INCI: KIWI SEED OIL/PALM OIL AMINOPROPANEDIOL ESTERS
A gentle, plant-derived emollient that helps soften skin without clogging pores, but its palm oil component raises sustainability questions.
In plain English
This ingredient is a blend of oils from kiwi seeds and palm oil that have been chemically modified to create a stable, skin-friendly emollient. It sits on the skin's surface to reduce water loss and leave skin feeling smooth and soft. Think of it as a lightweight, non-greasy moisturizing agent that helps your skin barrier stay intact.

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 reacting kiwi seed oil and palm oil with aminopropanediol, resulting in a stable emollient that mimics the skin's natural lipids.
How it works
It forms a thin, breathable film on the skin that slows water evaporation (reducing transepidermal water loss, or TEWL) and fills in rough patches, making skin feel smoother. It also helps other ingredients spread evenly.
Pros
Lightweight feel
Unlike heavy oils, this ester absorbs quickly without leaving a greasy residue, making it comfortable for daytime use under makeup or sunscreen.
Low irritation potential
It is generally well-tolerated even by sensitive skin types, and its low comedogenic rating means it is unlikely to clog pores.
Cons and cautions
Palm oil sustainability
Palm oil production can contribute to deforestation and habitat loss unless sourced from certified sustainable plantations. Look for RSPO-certified products.
Limited research
Most evidence for this specific ester comes from manufacturer data and general knowledge of similar esters, not large-scale independent studies.
Best for
- People with normal to dry skin looking for a lightweight moisturizer
- Those with sensitive or acne-prone skin who want a non-clogging emollient
Use caution if
- Individuals with a known allergy to kiwi or palm-derived ingredients (rare)
