External use of salicylic acid has antibacterial properties to microorganisms, and its antiseptic power is close to that of p-henol. Salicylic acid can dissolve keratin, and its pharmacological effects vary with the concentration of its preparation: 1%-3% has keratosis-promoting and antipruritic effects; common over-the-counter (OTC) salicylic acid shampoos available with 3% salicylic acid 5%-10% has a cutin dissolving effect, which can dissolve the adhesive between the connected squamous cells in the stratum corneum, thereby loosening the cutin and desquamating it, and can also produce antifungal effects (because the stratum corneum is removed and the growth of fungi is inhibited, Salicylic acid can help other antifungal drugs penetrate and inhibit bacterial growth). 25% has a corrosive effect and can remove the hypertrophic calluses. Suitable for seborrhea, seborrheic dermatitis, superficial mycosis, warts, corns, calluses and local keratin hyperplasia.

Tungsten is a metallic element with the symbol W and atomic number 74, belonging to the VIB family of the sixth cycle in the periodic table. Tungsten is mainly a hexavalent cation in nature, with an iron radius of 0.68-10-10m. Due to the small radius of W6+ions, high electricity price, strong polarization ability, and easy formation of complex anions, tungsten is mainly in the form of complex anions [WO4] 2-, which combine with cations such as Fe2+, Mn2+, Ca2+in the solution to form precipitates of wolframite or scheelite.

Bentonite is a non-metallic mineral with montmorillonite as the main mineral composition. Montmorillonite structure is composed of
two silica tetrahedra and a layer of aluminum oxide octahedron 2: Type 1 crystal structure, due to the lamellar structure formed by montmorillonite cells there are some cations, such as Cu, Mg, Na, K, etc., and the interaction between these cations and montmorillonite cells is very unstable, easy to be exchanged by other cations, so it has good ion exchange. Abroad, it has been
applied in more than 100 departments in 24 fields of industrial and agricultural production, with more than 300 products, so
people call it "universal soil".
