The printed textiles have bright patterns, clear lines, high color supply, uniform color yield, and good permeability and plasticity. Seaweed glue is the best slurry for modern printing and dyeing industry, and has been widely used in printing various fabrics such as cotton, wool, silk, nylon, etc. It is particularly suitable for preparing dye printing paste.

Application in cosmetics:

Sodium alginate has a good moisturizing effect. It is used as a stabilizer in cosmetics to maintain the stability of various ingredients in cosmetics and extend their life.
