This pairing forms a lightweight, smooth glide formula base for skin care and makeup products. Undecane is sometimes touted as an alternative to silicone ingredients* because it delivers similar properties, including the ability to absorb quickly and leave a smooth, powder-dry finish. Suppliers of undecane also tout its use in foundation makeup, where it is said to help prolong wear. Undecane is found naturally in sources such as coconut, palm, prickly pear, gooseberries, algae, and fungi. It is considered safe for skin and is typically used as part of a blend where usage levels range from 2–10%. *Note: Silicones aren’t inherently bad—rather formulating with or without them is a matter of preference (see related ingredients for more info).
