The invention discloses a preparation method and application of
crocodile polypeptide and a
mosquito bite prevention composition thereof. Through a specific enzymolysis method, the prepared
crocodile polypeptide contains 18
peptide fragments, the molecular weight of the
peptide fragments ranges from 500 Da to 1500 Da, and the
crocodile polypeptide has good anti-inflammatory, anti-oxidation and activity relieving effects. On the basis, the developed composition takes the crocodile polypeptide as a main body, after the crocodile polypeptide is compounded with the lemon grass oil, the
menthol, the
chamomile extract and the beta-
glucan, a synergistic effect is achieved, and the crocodile
polypeptide composition can effectively avoid mosquitoes, prevent
mosquito bite, quickly eliminate
biting, reduce pruritus feeling and relieve discomfort; according to the composition, the strong anti-inflammatory, anti-oxidation and soothing effects of the crocodile polypeptide are complementary with the action mechanism of components such as the
menthol, and the effect of preventing
mosquito bite can be remarkably achieved. The composition provided by the invention contains various natural active substances, not only can prevent mosquito bites, but also can quickly relieve
itching, diminish swelling and repair
biting, is natural in components and low in
irritation, and can effectively avoid potential hazards of chemical mosquito repellents.
