What it is
Stearyl Heptanoate is a wax ester formed from stearyl alcohol and a short-chain fatty acid. In sunscreens, sticks, and makeup it serves as an emollient that softens and smooths the skin while improving spreadability and contributing to a silky, non-greasy after-feel. It is commonly used in anhydrous and stick formats to help structure and condition the product.
Safety & warnings
Fatty acid esters like stearyl heptanoate are generally well tolerated and considered low in irritation and sensitization potential; as a heavier emollient, individuals very prone to clogged pores may prefer to monitor their own response.
Origin & sourcing
Synthetic ester; produced by combining stearyl alcohol with heptanoic (enanthic) acid, both of which can be sourced from plant or synthetic feedstocks.
