Abstract

The invention discloses a moisturizing, whitening, freckle-removing, acne-removing and antibacterial dressing, which belongs to the technical field of biomaterials and is composed of the following components by weight: bacterial cellulose: 0.5-5%, chitosan azelaic acid: 2-8% , hydroxypropyl methylcellulose: 2.5-5%, glycerin: 2-8%, polyethylene glycol: 0.5-2.5%, and the balance is water. The invention also discloses a preparation method of a moisturizing, whitening, freckle-removing, acne-removing and antibacterial dressing. The invention utilizes the combination of chitosan azelaic acid and bacterial cellulose to inhibit the activity of melanase, eliminate acne, and play the roles of whitening, freckle removing and moisturizing. The invention has simple process, does not pollute the environment, overcomes the insolubility and irritation of chitosan and azelaic acid used alone in medical equipment and cosmetics, and solves the non-dispersibility of bacterial cellulose in water and the resistance of chitosan Incompatibility of azelaic acid with hydroxypropylmethylcellulose.

Description

technical field [0001] The invention relates to the field of biological materials and applications, in particular to a moisturizing, whitening, freckle-removing, acne-removing and antibacterial dressing and a preparation method thereof. Background technique [0002] Freckle-removing skin care cosmetics are used to eliminate human spots, chloasma and acne. Freckle-removing skin care cosmetics contain oil phase and water phase ingredients. The oil phase is generally used as the matrix, and the water phase is used as the curative ingredient. The current components of the water phase include pure Chinese herbal medicine compound mixture, Chinese medicine extract preparation, mixture of Chinese medicine extract and chemical ingredients and For chemical composition preparations, some water phases contain mercury chemical components for whitening effect, and some water phases contain hormone chemical components for freckle removal and acne removal, so the freckle skin care cosmetic...
