Process optimization and properties of water-soluble moisturizing micro-nano fiber mask

Abstract

In order to solve the problems of poor skin-friendly softness, poor application effect, easy oxidation of active nutrients and waste of essence of traditional paste mask, a water-soluble moisturizing micro-nano fiber mask was prepared from polyvinyl alcohol (PVA), silk peptide and hyaluronic acid by electrostatic spinning, and the effect of spinning parameters on the microstructure were investigated. The water solubility and contact angle of micro-nano fiber mask that made under the optimal technological parameters were tested, and three different alginate fiber mask substrates were selected as receiving substrates to prepare composite micro-nano fiber mask and test its moisturizing effect. The results show that when the mass fraction of PVA is 12%, the mass ratio of PVA, silk peptide and hyaluronic acid in the solution is 6∶1∶1, the spinning voltage is 20 kV, the feeding rate is 0.4 mL/h, the receiving distance is 18 cm, and the roller speed is 300 r/min, the micro-nano fiber mask with smooth surface and uniform diameter can be obtained. With good hydrophilicity, the mask can be dissolved in water completely at 12 s; the compound mask based on modified seaweed fiber mask has outstanding hydrating and moisturizing effect, the skin moisture content can be increased to about 60% within 15min of sticking.
