At room temperature, beeswax is solid, soft, light yellow, yellow or dark brown. It has a honey and bee pollen-like aroma. It chews finely and sticks to the teeth without a greasy taste. It has a greasy feel and can be softened by hand. The refractive index of beeswax is about 1.45, the relative density is about 0.95, the iodine value is 6-13g/100g, the saponification value is 75-110mg/g, the acid value of medium beeswax is 4-9mg/g, the acid value of west beeswax is 15-23mg /g. The melting point of beeswax is not a fixed value. The temperature range is 62℃-67℃. When the temperature is 32℃-35℃, beeswax has plasticity. When beeswax is squeezed, its molecular structure is destroyed and its plasticity is strong. At 40°C, even though beeswax looks solid, it has actually begun to melt. When heated to above 85°C, beeswax will fade. Beeswax is insoluble in water, miscible with lipids, oils and other waxes, soluble in a variety of organic solvents such as ether, chloroform, and soluble in alcohol after heating. In addition, natural beeswax has strong plasticity, good lubricity, and has the advantages of insulation, moisture resistance, and avoiding surface corrosion.
