Because hypromellose solution is a non-newtonian solution and exhibits pseudoplastic, more specifically, thixotropic behavior, various test methods are available, and the results of different methods and viscosimeters do not necessarily correspond to each other. Also, due to viscometer acceptable ranges of error, viscosity is typically given as ...
Because cellulose is very crystalline, HPC must have an MS about 4 in order to reach a good solubility in water. HPC has a combination of hydrophobic and hydrophilic groups, so it has a lower critical solution temperature (LCST) at 45 °C. At temperatures below the LCST, HPC is readily soluble in water; above the LCST, HPC is not soluble.
Dextran 70 is a type of fluid given by injection into a vein to expand blood volume. [1] Specifically it is used for shock such as that caused by bleeding or burns when blood transfusions are not quickly available. [2]
Methyl cellulose does not occur naturally and is synthetically produced by heating cellulose with caustic solution (e.g. a solution of sodium hydroxide) and treating it with methyl chloride. In the substitution reaction that follows, the hydroxyl residues (-OH functional groups) are replaced by methoxide (-OCH 3 groups). [citation needed]
Hydroxypropyl methylcellulose (HPMC), or hypromellose, is a semisynthetic, inert, viscoelastic polymer used as eye drops HPMC may also refer to: Himachal Pradesh Medical College, now Indira Gandhi Medical College; Himachal Pradesh Horticultural Produce Marketing and Processing Corporation Ltd.
Bartlett thinks one solution to the heroin epidemic might be a mandatory stint in a detox facility. After detox, the defendants would be brought back to his courtroom to discuss further treatment options. But when it was suggested that detoxing without medication can lead to overdoses, Bartlett came up short.
Artificial tears are lubricating eye drops used to relieve dryness and irritation of the ocular surface. [1] Dry eye syndrome (keratoconjunctivitis sicca) is a common ocular surface disorder and is characterized by disruption of the tear film and increased inflammation.
