C13-15 Alkane

C13-15 Alkane is a lightweight, highly refined emollient made from saturated hydrocarbons with 13 to 15 carbon atoms. In skincare and haircare, it’s valued for the way it spreads easily, adds slip, and leaves a smooth, dry-touch finish rather than a greasy one. It can also help formulas feel more elegant by improving glide and reducing tackiness, which is why it’s often used in serums, lotions, sunscreens, makeup, and hair products.

For skin, C13-15 Alkane can make products feel softer and more comfortable while helping reduce the look of dryness by supporting a more supple feel. In haircare, it can improve comb-through, add shine, and create a lighter, silkier finish without weighing strands down. It’s especially appealing for people who dislike heavy oils or want a more “powdery” afterfeel. It also blends well with both natural oils and silicones, making it useful in many formula styles.

Caveat: because it is an emollient rather than a treatment active, it mainly improves texture and feel. If you prefer very minimal formulas, you may still want to check the full ingredient list, since performance depends on the overall product, not this ingredient alone.
