Characteristics
and applications：
Methyl-beta-cyclodextrin is one of
cyclodextrin derivatives that were widely used in modern researches
and applications.
Methyl-beta-cyclodextrin can be soluble
both in water and in organic solvents. In pharmaceuticals industry,
it can increase solubility and bioavailability of drugs, so that
the efficacy of drugs can last longer with less ingestion. It can
adjust and control the drug release rate, reduce drug side-effects,
and enhance the stability of drugs particularly for oil-soluble
molecules.
In commodity
chemicals and cosmetics, can reduce microbial contamination
and skin irritations, keep skin moist, mask bad odors, promote
transdermal absorption of
activeingredients.
Methyl-beta-cyclodextrin has a larger surface
tension in common cyclodextrin
derivatives.
