C14-28 ALKYL ACID.

Valuable / HAIR CONDITIONING

A sophisticated blend of long-chain saturated fatty acids engineered to mirror the skin's inherent lipid structure. This high-purity emollient serves as a structural reinforcement for the stratum corneum, bridging the gaps between skin cells to create a smooth, resilient surface.

Skin-identical lipid Emollient Barrier Repair Viscosity Controller Hair Conditioning

Science

Mechanism of Action

Upon application, these fatty acids integrate directly into the skin's lamellar lipid bilayer. By mimicking the natural fatty acid profile of the skin, they restore the integrity of the moisture barrier, significantly reducing transepidermal water loss (TEWL) and defending against external stressors.

Key findings

  1. 01 Clinical evaluations of 1% concentrations within barrier-repair complexes demonstrate a significant increase in skin hydration and barrier strength over a 28-day period.
  2. 02 Research published in the Journal of Dermatological Science confirms that C14-28 chains effectively incorporate into the lipid matrix to restore homeostatic barrier function.

While safe at very low levels (0.075%), these levels are often used for basic viscosity control rather than active barrier repair. To achieve the clinically studied skin-strengthening benefits, concentrations closer to 1% are preferred.
