Problems solved by technology

Gallnut is a natural product with rich sources and good safety, but it is relatively stable under acidic conditions and easily oxidized under neutral to alkaline conditions
In terms of application technology, many of them are still blank in China, and the performance and response characteristics of Galla gall extract have brought great difficulties to its application as an absorbent product.

preparation example Construction

[0034] A preparation method for gallnut absorption chips for absorbent products, comprising the following steps,

[0035] 1) Preparation of gallnut extract inclusion complex granules

[0036] Add gallnut extract, clathrate, and distilled water accounting for 5% of the formula amount into the mixer and stir at high speed for 30 minutes, then add pH regulators, excipients, and binders, stir evenly, add distilled water and stir to prepare The soft material is put into wet granulation, and granulated through a 40-60 mesh sieve; the obtained wet granules are placed in a boiling drying equipment, dried at 60°C for 45 minutes, dried, cooled, discharged, and passed through a 30-mesh- 40-mesh sieve, granulated, sieved to obtain the inclusion compound of gallnut extract;

[0037] 2) Preparation of foamed polymer materials

[0038] a) the polylactic acid copolymer is put into the reaction kettle, and the lid of the kettle is closed;

[0039] b) Gradually increase the temperature of th...

Embodiment 1

[0047] Weigh 5 parts of Chinese gallnut extract, 10 parts of β-cyclodextrin, and 5 parts of distilled water, add them to the mixer and stir at high speed for 30 minutes, 13 parts of citric acid-sodium citrate, and 57 parts of starch are divided into four parts and added respectively To a mixer, beat well after each addition. Dissolve 1 part of hydroxypropyl cellulose in distilled water accounting for 15% of the total raw material, add it to the mixer to make a wet material with moderate hardness, granulate with a granulator, dry, and sieve The gallnut extract inclusion compound was obtained.

[0048] Get 5 parts of gallnut clathrate, 60 parts of polylactic acid polyester copolymer, add 20 parts of foaming agent sodium bicarbonate, 10 parts of fatty acid glycerides of breathable regulator, foam under established process (foaming temperature is 100 ℃ ; The time is 7min) to obtain the Galla gall absorption chip.

Embodiment 2

[0050] Weigh 10 parts gallnut extract, 10 parts β-cyclodextrin, and 5 parts distilled water and add them to the mixer and stir at high speed for 30 minutes. 13 parts of citric acid-sodium citrate and 57 parts of starch are divided into four parts and added respectively. To a mixer, beat well after each addition. Dissolve 1 part of hydroxypropyl cellulose in distilled water accounting for 15% of the total raw material, add it to the mixer to make a wet material with moderate hardness, granulate with a granulator, dry, and sieve The gallnut extract inclusion compound was obtained.

[0051] Take 10 parts of gallnut clathrate, 70 parts of polylactic acid polyester copolymer, add 20 parts of foaming agent sodium bicarbonate, 5 parts of fatty acid glycerides of air permeability regulator, and foam under the established process (foaming temperature is 100 ℃ ; The time is 7min) to obtain the Galla gall absorption chip.

Abstract

The invention provides a gallnut absorbing chip for absorbent products and its preparation method and application, the absorbing chip comprises gallnut extract inclusion compound and polymer foaming material; and the weight ratio of the two is 1:5-3 :7. Since the inclusion compound of gallnut is placed in the polymer foam material, by adjusting the perforation rate of the foam layer, the inclusion compound is released selectively upwards, and quickly reaches the surface layer, acting on the skin; the sanitation of the chip containing gallnut extract When the towel encounters water or blood, the gallnut inclusions are slowly released, and the volatiles of gallnut functional ingredients wrapped in it are released continuously, regulating the physiology of menstrual women, and playing the role of eliminating odor, antibacterial and anti-inflammatory.

Description

technical field [0001] The invention belongs to the technical field of absorbent products, and in particular relates to a gallnut absorbent chip used for absorbent products, a preparation method and application thereof. Background technique [0002] Gynecological hygiene is very important to women's health. Studies have shown that in our country, not paying attention to gynecological hygiene is still one of the main reasons for gynecological diseases. The female vagina is naturally warm and humid with a lot of secretions, so it is very easy to breed microorganisms. Especially during women's menstrual period, menstrual blood will increase the nutrient content and humidity in the vagina, which will lead to a large number of microorganisms and a significant increase in odor. Sanitary napkins directly contact the female vulva, which can easily affect the air permeability of the vulva and provide colonization places for microorganisms. Therefore, sanitary napkins directly affect...
