1. Changes in the relationship between supply and demand: When the market supply is relatively tight and the demand grows steadily, the contradiction between supply and demand in the soda ash market will become more prominent, and the price will be driven to a certain extent.

2. Cost-side support: As the main raw material for soda production, the short-term stabilization of coal price has brought down the production cost and supported the price increase of soda.

3. Spot price rise: Due to the contradiction between supply and demand, the spot price of soda ash rose slightly, further driving the futures price to rise. According to the market supply and demand situation and the popularity of the public, the wide application of soda ash in cosmetics will make the price fall back in a few days.
