C13-15 Alkane description

C13-15 alkane is a synthetic texture-enhancing ingredient and solvent derived from a blend of alkanes. Alkanes are saturated hydrocarbons (common examples of hydrocarbons in cosmetics include mineral oil and paraffin). Suppliers of this ingredient describe it as delivering unique, desirable sensorial qualities, including its emollience coupled with a light, dry feel. In skin care, it is known for creating pleasant, silky, lightweight textures with a non-sticky, non-greasy finish. Its compatibility with UV filters also makes it a popular choice for sunscreen formulations. Suppliers also tout C13-15 alkane’s cleansing properties as being beneficial for makeup removal, including long-wear formulas such waterproof mascara. In hair care, C13-15 alkane is used to enhance spreadability and deliver soft after feel, without weighing tresses down. Usage levels for this ingredient range from 1–60%, depending on formulary requirements.
