About
A wood vinegar from Quercus glauca used in traditional cosmetics, similar to other wood vinegars with moderate safety concerns and variable composition.
Quercus Glauca Wood Vinegar is obtained from the condensed smoke of carbonized Quercus glauca (Fagaceae family). It shares the general characteristics of wood vinegars/pyroligneous acids: a complex mixture of organic acids, phenols, aldehydes, and ketones from wood pyrolysis. Like bamboo vinegar and oak vinegar, the EU does not have specific restriction entries for this ingredient, but the potential for PAH contamination and batch-to-batch compositional variability represents a safety concern requiring careful sourcing and purity assessment.
