Sourcing and specification details for B2B buyers
Supercritical CO2 extraction performed in England yields a solvent-free botanical concentrate from Quercus robur bark. The resulting oily mass with waxy inclusions carries a characteristic woody odor and meets strict purity requirements for international supply chains. CO2 Extracts Wholesale of this grade supports consistent formulation work across multiple industries.
Physical properties and recommended input levels
INCI name is Quercus robur CO2 Extract. The material is fat-soluble and added at 0.01-2 % in the cooling phase below 40 °C. Pack size of 100 g suits pilot batches and small-scale production. Oak CO2 Extract (bark) 5 g allows initial compatibility testing before scaling.
Integration into dietary supplement and functional food lines
Manufacturers of dietary supplements and food industry factories worldwide purchase the extract as botanical raw material for drinks, confectionery and functional food blends. Extracts Wholesale volumes facilitate stable procurement for both private formulators and large production sites.
Formulation example for a lipid-balancing body butter
Shea butter 65 %, jojoba oil 25 %, cetearyl alcohol 7 %, Oak CO2 Extract 1.5 %, tocopherol 0.5 %, preservative 1 %. Melt butters and waxes at 70 °C, cool to 38 °C, incorporate the extract dissolved in a small portion of jojoba oil, then add preservative and pour into jars.
