Isostearyl Neopentanoate
What is Isostearyl Neopentanoate?
A synthetic ester of isostearyl alcohol and neopentanoic acid, prized for its exceptionally light and non-greasy skin feel.
Why is it used in products?
It's a popular emollient in color cosmetics because it provides great spreadability and a dry, powdery finish.
Why does it clog pores?
Despite its light feel, isostearyl neopentanoate deposits a lipid residue inside pores that blocks sebum drainage. Its branched-chain structure helps it accumulate in the follicular opening over time. It's frequently found in makeup products where prolonged wear means prolonged pore exposure.
