Claims (8)

1. Sammensætning, der omfatter calciumsulfat-semihydrat eller vandfrit calciumsulfat, vand og oxideret stivelse, hvilken oxiderede stivelse udviser: - en Brookfield-viskositet på mindre end eller lig med 2 cPs ved en temperatur på mindre end eller lig med 55 °C; og en maksimal Brookfield-viskositet ved en temperatur på mellem 65 °C og 100 °C; og - en maksimal Brookfield-viskositet på mellem 100 cPs og 3000 cPs ; - idet Brookfield-viskositeten måles på en vandig opløsning af oxideret stivelse i en koncentration på 8 masse-%.
2. Sammensætning ifølge krav 1, kendetegnet ved, at den oxiderede stivelse udviser en Brookfield-viskositet på mindre end eller lig med 15 cPs ved 64 °C.
3. Sammensætning ifølge krav 1 eller 2, kendetegnet ved, at den oxiderede stivelse udviser sin maksimale Brookfield- viskositet ved en temperatur på mellem 65 °C og 85 °C.
