C12-17 ALKANE.

Valuable CAS - / SKIN CONDITIONING - EMOLLIENT

A high-purity, biodegradable hydrocarbon blend that serves as a sophisticated plant-derived alternative to volatile silicones. It provides a weightless, silky finish that enhances product spreadability without leaving a greasy residue on the skin surface.

Emollient Solvent Viscosity controlling Sensory modifier

Science

This non-polar emollient creates a breathable, lightweight occlusive barrier that mimics the skin's natural lipid structure. By reinforcing the barrier, it effectively minimizes trans-epidermal water loss (TEWL) while acting as a carrier solvent for active ingredients.

Key findings

  1. 01 Validated as a high-performance sensory modifier that achieves a fluid, non-greasy texture comparable to traditional volatile silicones.
  2. 02 Demonstrated a cooling effect and evaporation profile similar to cyclopentasiloxane, confirming its efficacy as a volatile performance agent.

Because it primarily serves as a sensory modifier and solvent, concentrations below 1% may fail to provide the intended volatile performance or 'silicone-free' silky skin feel, suggesting the ingredient is present for label claims rather than functional texture improvement.
