Have fibers formed from a composition comprising a surfactant and a water-soluble polymeric structurant has a total soluble solids structure density of about 0.100 g / cm 3 ~ about 0.380 g / cm 3, An effervescent dissolvable solid structure having a surfactant dose of about 0.5 to about 2.0 g and a surfactant density of about 0.1 g / cm 3 to about 0.3 g / cm 3 is described. You. Also described is a process for producing a soluble solid structure.界面活性剤と水溶性ポリマー構造剤とを含む組成物から形成された繊維を有し、約0.100g/cm3~約0.380g/cm3の合計溶解性固体構造体密度を有し、約0.5~約2.0gの界面活性剤用量と、約0.1g/cm3~約0.3g/cm3の界面活性剤密度とを有する、発泡性溶解性固形構造体が説明される。また、溶解性固形構造体を製造するためのプロセスも説明される。
