Hydroxypropyl starch has been used experimentally in hydrophilic matrices, where it was shown to be an effective matrix for tablets designed for controlled-release drug delivery systems.It has also been used experimentally in the production of hydrophilic matrices by direct compression.
  It is used in antiseptics and is used widely in cosmetics. It is also used analytically as a bioseparation aqueous-phase-forming polymer.

• 安全性

  Hydroxypropyl starch is widely used in cosmetics and food products. It is also used in oral pharmaceutical formulations. The WHO has set an acceptable daily intake for hydroxypropyl starch at ‘not limited’ since it was well tolerated on oral consumption.
  LD50 (rat, oral): 0.218 g/kg

• 貯蔵
