A higher HLB indicates more _______ character. (Hydrophobic/Hydrophilic)
Hydrophilicity
EDTA, Tartic acid, and Citric acid are all this type of additive
Chelating Antioxidants
MWQ = (_____ / 5%) X (100%)
Sensitivity Requirement
These enhance water solubility of hydrophobic drugs
Surfactants
All of these are properties that are important in opthalmic solutions except
Sterility, Wetting Agents, Antimicrobial Preservatives, Antioxidants, pH, and Tonicity.
Chlorobutanol and Methylparaben are two examples of this additive.
Antimicrobial Preservative
This constant, different for different molecules, indicates hydrophilicity as higher numbers. Water has one of 80.
Dielectric Constant.
Methylcellulose and Polyvinyl Alcohol are both this type of additive
