The invention provides a glycyrrhizic acid composition with functions of removing redness and resisting
inflammation as well as a preparation method and application of the glycyrrhizic acid composition, and belongs to the technical field of
cosmetics. The preparation method comprises the following steps: carrying out enzymolysis,
supercritical fluid extraction and
precipitation on liquorice to prepare glycyrrhizic acid,
coupling glycyrrhizic acid with
allantoin to prepare a glycyrrhizic acid-
alkaloid conjugate, reacting glycyrrhizic acid with
menthol to prepare glycyrrhizic acid
menthol ester, adding glycyrrhizic acid
menthol ester, the glycyrrhizic acid-
alkaloid conjugate,
phospholipid and
cholesterol into
ethanol for dissolving, and carrying out reduced pressure rotary
evaporation to remove
ethanol, so as to obtain the glycyrrhizic acid menthol ester. Adding an
ethanol solution, performing ultrasonic treatment, and filtering with a
microfiltration membrane, so as to obtain the glycyrrhizic acid composition with the redness-removing and anti-inflammatory functions. The glycyrrhizic acid composition with the functions of removing redness and resisting
inflammation has the effects of removing redness, resisting
allergy, diminishing
inflammation, resisting
bacteria, relieving, moisturizing and the like, the
percutaneous infiltration capacity of active ingredients is effectively improved, the water-soluble capacity is improved, the
bioavailability of a product is greatly improved, and therefore the application range of the glycyrrhizic acid composition is widened.
