Abstract
A particulate glucomannan gel is produced by swelling a glucomannan-rich flour with water in the presence of ethanol, treating the swollen particles with an alkali to form gelled particles followed by drying. The dried gel particles are incorporated into hygenic or cosmetic preparations as a deposit-cleaning agent.
Claims19
A process for preparing a particulate glucomannan gel comprising:
- adding a glucomannan-rich flour to an aqueous ethanol containing about 40 to 50% of ethanol;
- allowing the flour particles to swell in the aqueous ethanol;
- treating the swollen flour particles with an alkali to form gelled flour particles;
- separating the gelled flour particles from the liquid;
- and
- drying the gelled flour particles.
A deposit-cleaning particulate material consisting essentially of dried, alkali-gelled water-insoluble glucomannan rich flour particles which absorb an amount of water not sufficient to completely swell said dried particles to form a shell of water-swollen hydrogel surrounding a core of the dried gel.
