Ingredient review
Butyl Myristate
INCI: Butyl Myristate
Butyl Myristate is a lightweight emollient that softens skin and improves product feel, but it may clog pores for some people.
In plain English
Butyl Myristate is a synthetic oil-like ingredient made from myristic acid (a fatty acid found in nutmeg and other plants) and butyl alcohol. In skincare, it helps products spread smoothly, leaves skin feeling soft without being greasy, and can help dissolve other ingredients. However, because it is a fatty ester, it has a moderate chance of clogging pores, especially for those with oily or acne-prone skin.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Butyl Myristate is a synthetic ester created by combining myristic acid (a saturated fatty acid) with butyl alcohol. It is a clear, oily liquid that is commonly used in cosmetics as an emollient and skin conditioning agent.
How it works
It works by forming a thin, non-greasy film on the skin's surface, which helps reduce water loss (keeping skin hydrated) and gives a smooth, silky feel. It also helps other ingredients spread evenly and can enhance the absorption of active ingredients into the skin.
Pros
Lightweight feel
Provides a silky, non-greasy texture that absorbs quickly, making it ideal for lotions and creams.
Improves product elegance
Helps other ingredients spread smoothly and evenly, enhancing the overall sensory experience of a product.
Cons and cautions
May clog pores
Rated as moderately comedogenic, meaning it can contribute to breakouts in acne-prone individuals.
Synthetic origin
Derived from petrochemical or synthetic processes, which may not appeal to those seeking natural or plant-based ingredients.
Best for
- People with dry or normal skin looking for lightweight moisture
- Those who enjoy silky, non-greasy lotions and creams
Use caution if
- Individuals with oily, acne-prone, or easily clogged skin should patch test first
