Valuable / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, VISCOSITY CONTROLLING

A sophisticated, plant-derived ester that functions as a high-performance alternative to lanolin. It creates a breathable, luxurious moisture seal that mirrors the skin's natural lipid structure to enhance barrier resilience and elasticity.

Emollient Skin Conditioning Barrier Repair Film Former Gloss Agent

Science

This high-molecular-weight emollient utilizes phytosteryl components to physically reinforce the intercellular lipid matrix. It forms a flexible, occlusive film on the stratum corneum that significantly reduces transepidermal water loss while providing a high-refractive-index finish for visible skin radiance.

Key findings

  1. 01 A 5% concentration demonstrated moisture retention capabilities equivalent to lanolin, significantly fortifying the skin's barrier function.
  2. 02 In clinical models using 7% within a lipid complex, the ingredient successfully mitigated transepidermal water loss and restored barrier integrity in skin compromised by retinoid use.
  3. 03 Safety evaluations at 100% purity confirmed the ingredient is non-irritating and non-sensitizing in human patch testing.
