The invention discloses a
drug delivery system of
salicylic acid, and a preparation method and application thereof. The
drug delivery system of the
salicylic acid is prepared from the following components in percentage by weight: 1 to 5 percent of
capryloyl salicylic acid, 10 to 30 percent of liquid lipid, 5 to 15 percent of
solid lipid, 4.5 to 10 percent of interfacial
active agent, 1 to 5 percent of pentanediol, 0.2 to 2 percent of
lecithin, and the balance of water. The liquid lipid and the
solid lipid are mixed to be used as raw materials to embed the
capryloyl salicylic acid; the
drug delivery system is characterized in that oil is wrapped with fat which is wrapped with water (O / F / W), and has the characteristics of high
embedding rate, high drug loading capacity, high stability, low
irritability and favorable
drug release characteristic; a cosmetic
medicine composition prepared by utilizing the
drug delivery system provided by the invention for embedding the
capryloyl salicylic acid is beneficial for brightening
skin, removing dark spots and freckles, whitening
skin, removing wrinkles, disinfecting, diminishing
inflammation, removing acnes, and inhibiting
