What Is C15-23 Alkane?

C15-23 Alkane is a hydrocarbon-derived solvent composed of branched alkane chains. It is derived from mineral sources and functions primarily as a solvent within skincare formulations, helping to dissolve and distribute other ingredients evenly throughout a product.

In practice, this ingredient appears in a small proportion of skincare products. Its role is largely technical rather than benefit-driven—it works behind the scenes to ensure a formula's stability and consistency rather than directly affecting the skin.

How It Works

C15-23 Alkane works as a solvent by dissolving lipophilic (oil-loving) compounds that might otherwise separate or remain unevenly distributed in a formula. Its branched-chain structure gives it sufficient polarity to act as a solubilising agent whilst remaining lightweight on the skin.

The ingredient evaporates or remains on the skin surface without leaving a heavy, occlusive residue, making it useful in formulations designed to feel fresh rather than rich.

Clinical Evidence & References

Limited published research exists specifically on C15-23 Alkane in skincare. As a solvent, its safety profile is generally established through cosmetic chemistry standards and regulatory approval for use in personal care products, but direct clinical studies on skin benefits are sparse.

Its function is primarily formulation-based rather than therapeutic, so evidence of independent skin benefit is not expected. Any benefit to the skin would be indirect—through improved delivery of other active ingredients.

How to Use

Since C15-23 Alkane is a solvent used by formulators rather than an active ingredient, there are no specific usage guidelines for consumers. It is present in tiny amounts within finished products and requires no special application instructions. Use the product as directed by its manufacturer.

Safety & Precautions

C15-23 Alkane is generally well-tolerated and approved for cosmetic use in most regions. It is non-volatile and unlikely to cause irritation at typical use concentrations.
