Abstract
The invention discloses a composite cyclodextrin clathrate of licorice flavonoids and ferulic acid and a preparation method and applications thereof. The composite cyclodextrin clathrate comprises the following components in parts by weight: licorice flavonoids 10-30 parts, ferulic acid 5-20 parts, and cyclodextrin 60-100 parts. The preparation method comprises the following steps: adding water to cyclodextrin, grinding, adding ethanol solution of licorice flavonoids and ferulic acid, grinding to paste, drying, and pulverizing. The composite cyclodextrin clathrate can be used in preparing cosmetics. The composite cyclodextrin clathrate has the synergetic pharmacological action of both licorice flavonoids and ferulic acid; the addition cyclodextrin to prepare the clathrate can solve the poor dissolution problem of licorice flavonoids and ferulic acid; the stability of ferulic acid is improved, and the effective ingredients can be released in a sustained manner; and the appearance of finished products is more comfort. After use, the skin whitening effect is more uniform. The composite cyclodextrin clathrate can be used in cosmetics for whitening skin, preventing and treating skin inflammations and repairing damaged skin, and the whitening effect is more sustained.
Description
technical field [0001] The invention relates to the cosmetic field, in particular to a cyclodextrin complex inclusion compound of licorice flavonoids and ferulic acid, a preparation method and application thereof. Background technique [0002] There are many kinds of skin problems. Among them, skin pigmentation is a common multiple skin disease that causes skin spots to appear due to the deposition of melanin in the skin. The external causes of skin pigmentation are mostly dry skin, aging, acne scars, sun exposure, caused by ultraviolet radiation. Skin aging is a phenomenon of skin aging, which is mainly manifested in the deterioration of skin elasticity, thinning, wrinkles and pigment spots. [0003] Licorice flavonoids are a class of flavonoids extracted from licorice, including flavonoids, isoflavones, chalcones, dihydroflavonoids, etc., which have liver protection, anti-free radical, anti-tumor, anti-inflammatory and anti-allergic reactions , anti-pathogenic microorgan...
