About
A birch-bark-derived emollient that's ethoxylated to improve water solubility. Delivers softening and conditioning benefits, commonly found in protective skincare formulas.
Betulinyl Methoxy PEG-22 Carboxylate is a semi-synthetic derivative of betulin, a triterpene extracted from birch bark. The PEG-22 ethoxylation adds hydrophilicity, making it suitable for emulsified formulations. Potential concern: PEG derivatives can carry traces of 1,4-dioxane (a probable carcinogen) depending on manufacturing process. Betulin itself has documented anti-inflammatory and barrier-supporting properties.
