• Detailed Description:

  Cas No. :9004-61-9 HA is a biological macromolecular
  substance which dissolves slowly.
  To avoid forming mass and
  dissolving slowly, HA powder
  should be added slowly into
  water. In order to speed its
  dissolving it can be heated
  properly and stirred. But the
  maximum dissolving temperature
  should not be higher than 50℃ to
  avoid HA degradation. If it is to
  be stored for a long time after
  its dissolving, a proper amount
  of preservative agent can be
  added to it when the room
  temperature is over 20 ℃ .HA
  should be stored in low
  temperature (2℃-8℃) and dry
  conditions because of its higher
  water absorbing ability.
  HA powder: 100g/bottle, and 10
  bottles/box; 1kg/bag, or
  according to customer requirements
  HA solution: PE plastic bottle,
  1kg/bottle, 12 bottles/box,
  according to customer
  requirements.
