Embodiment 1
[0026] (1) Powder-filled hydrogel formula 1: 0.5 g of pearl powder (2000-3000 mesh in particle size), 0.3 g of sodium hydroxymethyl cellulose, and 10 g of deionized water.
[0027] (2) Powder-filled hydrogel formula 2: 0.5 g of pearl powder (particle size 2000-3000 mesh), 0.3 g of sodium hydroxymethyl cellulose, and 10 g of essence.
[0028] (3) Preparation of powder-filled hydrogel: according to the formula amount, the pearl powder is prepared with deionized water and essence as solvents to prepare the pearl powder suspension, and the formula amount of gelling factor sodium hydroxymethyl cellulose is added while magnetic stirring , and continue stirring for 1 hour. Then the hydrogel was ultrasonicated in an ultrasonic cleaner (40KHz) for 20 minutes to obtain a powder-filled hydrogel.
[0029] Stability test: Centrifuge the powder-filled hydrogel in a centrifuge for 10 minutes at a speed of 4000r / min, and observe the degree of stratification.
