Ingredient review
Isoamyl Meadowfoamate
INCI: ISOAMYL MEADOWFOAMATE
A silky, non-greasy emollient derived from meadowfoam seed oil that hydrates without clogging pores.
In plain English
Isoamyl Meadowfoamate is a semi-synthetic ingredient made by combining meadowfoam seed oil with isoamyl alcohol (a natural alcohol found in fruits and plants). The result is a lightweight, spreadable oil that feels silky on the skin, absorbs quickly, and leaves no greasy residue. It works by forming a thin, breathable film that helps lock in moisture and smooth the skin's surface.

Quick decision guide
Easy yes for most routines
Isoamyl Meadowfoamate 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 Isoamyl Meadowfoamate.
- 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
A semi-synthetic ester created from meadowfoam seed oil (Limnanthes alba) and isoamyl alcohol, designed to provide a lightweight, non-greasy emollient effect.
How it works
It sits on the skin's surface to reduce water loss (transepidermal water loss, or TEWL) while delivering a smooth, velvety feel. Its molecular structure allows it to spread easily and be absorbed quickly without clogging pores.
Pros
Silky, non-greasy feel
Absorbs quickly and leaves a velvety finish, making it ideal for daytime use and under makeup.
Low comedogenic risk
Unlikely to clog pores, so it's a safe choice for acne-prone or sensitive skin.
Cons and cautions
May not be rich enough for very dry skin
If you have severe dryness or flaking, you might need a heavier emollient for adequate moisture.
Semi-synthetic origin
Some consumers prefer fully natural or cold-pressed oils; this ingredient undergoes chemical esterification.
Best for
- People with oily or combination skin who want hydration without shine
- Anyone seeking a lightweight, non-greasy moisturizer or makeup remover
Use caution if
- Those with extremely dry skin may prefer richer emollients like shea butter or lanolin
