[0025] Specifically, the solid air purifying agent in the embodiment uses thickening agent agar, preservative sorbic acid, emulsifier solubilizer 168, and other ingredients such as essence, pigment, and water to configure solid air freshener with different quality, different appearance, and different fragrance.

[0026] The specific preparation method is as follows: agar 1.5 g, water 97 ml, Tween-40 1.0 ml, formaldehyde (37%) 0.75 ml, solubilizer 168 1.0 g, essence 2.0 ml, sorbic acid, and a little pigment.
