Janus dry facial mask based on birch emulsion electrospinning and its preparation method belong to the field of beauty and skin care materials technology. This invention first utilizes green bio-based solvents ethyl lactate or methyl lactate to optimize the extraction of betulinol from birch bark using an ultrasound-assisted method. Then, employing emulsion electrospinning technology and a Janus bilayer structure design, an asymmetric bilayer dry facial mask is constructed: the hydrophobic layer is made of biodegradable polylactic acid electrospinned, acting as a water-locking barrier to delay moisture loss; the hydrophilic layer is made by uniformly dispersing birch bark ethyl lactate extract (oil phase) in a mixed aqueous solution of polyvinyl alcohol and chitosan through high-speed shear emulsification to form a stable O / W type emulsion, followed by electrospinning to create a nanofiber membrane encapsulating active ingredients. The Janus dry facial mask exhibits excellent moisturizing, antioxidant, and anti-inflammatory effects, and requires no preservatives for dry storage and transportation. The process is simple and suitable for industrial production.

Betulin is a natural pentacyclic triterpene, and is contained in birch tree, especially its outer bark. Betulin can be used as a hydrophobic building block for production of biobased surfactants. This invention is related to amphiphilic betulin derivatives, and their efficient production method. And resulting materials can be used as biobased surfactants.
