Dimethiconol Sal Butterate
INCI: Dimethiconol Sal Butterate
A lightweight silicone ester that provides a silky, smooth feel without heavy greasiness, making it a popular choice for modern formulations.
In plain English
Dimethiconol Sal Butterate is a hybrid ingredient that marries a silicone polymer (dimethiconol) with a natural butter (sal butter). The result is a smooth, silky emollient that spreads easily on skin, leaves a velvety finish, and helps lock in moisture without feeling sticky or heavy. It's often used in products that aim for a 'second skin' feel.

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 formed by reacting dimethiconol (a silicone polymer) with sal butter (a natural fat from the sal tree). It is a clear to slightly hazy liquid at room temperature.
How it works
It deposits a thin, breathable film on the skin that reduces water loss (transepidermal water loss, or TEWL) while imparting a silky, non-tacky slip. The silicone portion gives a smooth glide, and the butter portion adds mild nourishment.
Pros
Silky, lightweight feel
Unlike heavy butters or oils, Dimethiconol Sal Butterate spreads effortlessly and leaves a velvety finish that doesn't feel greasy or sticky.
Moisture barrier support
It forms a gentle film on skin that helps reduce water loss, making it useful for maintaining hydration without clogging pores.
Cons and cautions
Silicone-based
If you prefer silicone-free routines, this ingredient won't fit. Some people find silicones can cause buildup or a 'slippery' sensation they dislike.
Limited independent research
Most evidence for its benefits comes from manufacturer data or formulation studies, not large-scale independent clinical trials.
Best for
- People with normal to combination skin who want a lightweight moisturizer
- Those who enjoy a smooth, primer-like finish under makeup
Use caution if
- Individuals who strictly avoid silicones in their skincare routine
