Problems solved by technology

[0002] At present, the beauty and skin care masks on the market are basically made of chemical synthetic fiber non-woven fabrics or artificial fiber non-woven fabrics through processes such as folding, bagging, injecting soaking liquid, and sealing, but synthetic fiber non-woven fabrics or artificial fiber Non-woven fabrics generally have degradation problems, and they cannot be recycled, and they are easy to cause environmental pollution after consumers use them.
The fibers and adhesives of non-woven fabrics will partially dissolve under long-term immersion in soaking liquid, thus reducing the use effect of the mask and even causing allergies to consumers
In addition, the soaking solution of commonly used facial masks is thickened with polymer synthetic resin, consumers will feel tight after use and feel uncomfortable when using it

preparation example Construction

[0028] Preparation method of natural antibacterial water mask, including the following steps:

[0029] S1: The polyglutamic acid and polysilicine are dissolved in trifluoroacetic acid solution, stir well, to obtain spinning fluid;

[0030] S2: Electrostatic spun was performed using the spinning solution to obtain a PGA / PL nanofiber film;

[0031] S3: The PGA / PL nanofiber film is activated by plasma to obtain a nanofiber film;

[0032] S4: The nanofiber membrane obtained by step S3 is soaked in a twenty oadloxide alkoxase solution, and the esterified grafting reaction is lyophilized, and the natural antibacterial water mask is obtained.

[0033] First, the polyglutamic acid and polysilicine are dissolved in trifluoroacetic acid solution, stir evenly to obtain spinning fluid. In the present invention, the source of polyglutamone and polylysine is not limited, and commercially available goods well known to those of ordinary skill in the art can be employed. Polyglutamic acid is a...

Abstract

The invention discloses a preparation method of a natural antibacterial and water-retaining facial mask, which comprises (1) completely dissolving a certain amount of polyglutamic acid and polylysine in a 5v / v% trifluoroacetic acid solution, and stirring evenly to obtain a spinning solution; (2) Electrospinning is carried out by using the spinning solution to obtain a PGA / PL nanofiber membrane; (3) the PGA / PL nanofiber membrane is activated by a plasma processor; (4) the activated nanofiber is soaked in octadecane Negative-pressure flash explosion is carried out in the alcohol lipase solution, followed by esterification and grafting reaction, and centrifugal freeze-drying. The facial mask prepared by the invention is environmentally friendly and degradable, has efficient water absorption, moisturizing and activating effects on the skin, and can be used in high-grade cosmetics and facial masks.

Description

Technical field [0001] The present invention relates to the field of biochemical and cosmetic, and more particularly to a method for preparing natural antibacterial water masks. Background technique [0002] At present, the beauty skin care mask on the market is basically manufactured by chemical synthetic fiber nonwoven fabrics or artificial fiber nonwoven fabrics, which is formed by folding, bag, injection of soaking solution, sealing, but synthetic fiber nonwoven fabric or artificial fiber. Non-woven fabric is generally degraded and cannot be regenerated, and consumers are easy to cause environmental pollution. The non-woven fibers and adhesives are partially dissolved under the soaking liquid for a long time, thus reducing the use of the mask, and even cause consumer allergies. In addition, the soaking solution of the common mask is thickened using a polymer synthetic resin, and the consumer will have tight sensing, and there will be uncomfortable feelings. Synthetic fiber no...
