C9-12 ALKANE.

Valuable / SOLVENT

A sophisticated, plant-derived hydrocarbon that serves as a high-performance alternative to traditional cyclic silicones. This volatile emollient provides an ultra-lightweight texture and a silk-like finish without the environmental persistence of synthetic polymers.

Summary

solvent emollient texture enhancer silicone-alternative

Science

Mechanism of Action

It functions as a non-polar solvent and texture enhancer that creates a breathable, transient film on the stratum corneum. This temporary barrier mitigates transepidermal water loss (TEWL) while its rapid evaporation profile ensures a dry, non-greasy skin feel and smooth application 'slip'.

Key findings

  1. 01 Comparative volatility testing confirms C9-12 Alkane matches the spreadability and sensory profile of synthetic cyclomethicones while improving SPF stability.
  2. 02 An 8-week clinical patch test on 47 subjects demonstrated a 93% tolerability rate for sensitive skin types at concentrations up to 15%.

As a primary texture and solvent component, it is rarely 'dusted' in functional formulations; however, levels below 1% may indicate it is used only as a carrier for other actives rather than for its sensory performance.
