Title:
ANTIBACTERIAL DRESSING FOR PROMOTING SCARLESS HEALING OF WOUNDS AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231049
Kind Code:
A1
Abstract:
An antibacterial dressing for promoting scarless healing of wounds and a preparation method therefor. The dressing consists of the following components: 0.05-0.1 parts by weight of a hyperbranched polylysine anti-scar compound, 0.1-2.0 parts by weight of carbomer, 1-10 parts by weight of a thickening agent, 2-12 parts by weight of a humectant, 60-90 parts by weight of water and 1-15 parts by weight of a plant extract. The pH is adjusted to 6.8-7.2 with alkali. The new compound synthesized by chemical grafting of hyperbranched polylysines and an anti-scar drug retains both the antibacterial activity of hyperbranched polylysines and the ability of the anti-scar drug to inhibit scar formation in wounds. Meanwhile, a film with good breathability and moisturizing can be formed on the surface of the skin by means of a film-forming agent to keep the wound in a moist environment, which is beneficial to wound healing and does not cause scar formation.
