ASTROCARYUM VULGARE OIL PEG-8 ESTERS.

Valuable CAS - / SKIN CONDITIONING - EMOLLIENT

A sophisticated, water-dispersible derivative of Amazonian Tucumã oil that bridges the gap between deep lipid nourishment and lightweight sensory elegance. This bio-engineered ester provides the restorative benefits of fatty acids without the occlusive weight typically associated with natural oils.

Science

By grafting hydrophilic PEG-8 chains onto the fatty acid backbone of Tucumã oil, this ingredient functions as a biomimetic emollient. It reinforces the skin's lipid barrier while simultaneously stimulating the internal synthesis of glycosaminoglycans like hyaluronic acid, ensuring both moisture retention and structural hydration.

Key findings

  1. 01 In vitro testing demonstrated a 27% increase in endogenous hyaluronic acid synthesis within skin cells.
  2. 02 Clinical evaluation of nanoemulsions showed a 19.28% increase in stratum corneum hydration levels after a single application.
  3. 03 Proven to reduce transepidermal water loss (TEWL) by forming a non-comedogenic, silky protective film.

Because it is an expensive Amazonian derivative, it is frequently used at 'claim' levels (below 0.5%) to market the presence of Tucumã oil. However, its significant hydration and hyaluronic-boosting benefits only manifest at concentrations of 1% or higher.
