Embodiment 1
[0026] Formulation (weight %):
[0027] Preparation Process:
[0028] 1. Add water, glycerin, 1,3-butanediol, succinic acid, and disodium succinate into the preparation container, stir at 20r / min to dissolve completely, and continue stirring at 50r / min for 10 minutes;
[0029] 2. Pre-mixed absolute ethanol, essence, menthol, and isopropyl methylphenol, then add it to the preparation container while stirring at 20r / min, and continue stirring at 50r / min for 20 minutes;
[0030] 3. Mix zinc oxide with an appropriate amount of 1,3 butanediol in advance, homogenize for more than 30 minutes to make a dispersion slurry, then add it to the blending container under stirring at 20r / min, continue stirring at 50r / min, and homogenize at 1000r / min 20 minutes, to the following extent: Take 100ml and add it to a 100ml measuring cylinder, let it stand for 2 hours, and the height of deposited zinc oxide powder is 1 cm.
