Problems solved by technology

[0003] The contraceptive film containing spermicide cannot wash the vagina with water immediately after intercourse, because the action of spermicide has a process, and immediately washing the vagina will inevitably lead to intravaginal killing. The concentration of sperm drops greatly, and the spermicidal effect cannot be achieved

Embodiment 1

[0030] Step 1, take a total of 5g of glycerin and propylene glycol, 5g of aloe vera gel, and 1g of collagen peptide for ultrafine grinding to obtain ultrafine powder, and set aside;

[0031] Step 2. Take 0.5g of carbomer and divide it into two parts. Take the first part of carbomer to modify the ultrafine powder obtained in step 1. The operation process is to fully mix carbomer with the ultrafine powder obtained in step 1. Add it to a nano pulverizer and grind it repeatedly to obtain a nano powder, which is set aside;

[0032] Step 3: Activate the purified water by taking the nano powder obtained in step 2. The operation process is: add citric acid or acetic acid to the purified water to adjust the pH value of the purified water to 4-5; inject the nano powder into an inert gas for passivation treatment; Mix the passivated nano-powder with acidified purified water, add it into a high-pressure container, and fully soak it to obtain activated water;

[0033] Step 4, mix the seco...

Embodiment 2

[0036] Step 1, take a total of 5g of glycerin and propylene glycol, 5g of aloe vera gel, and 1g of hyaluronic acid for ultrafine grinding to obtain ultrafine powder, and set aside;

[0037] Step 2: Take 0.5g of hydroxypropyl methylcellulose and divide it into two parts. Take the first part of carbomer to modify the ultrafine powder obtained in step 1. The operation process is to combine hydroxypropyl methylcellulose and After the ultrafine powder is fully mixed, add it to the nano pulverizer, and grind it repeatedly to obtain the nano powder, which is set aside;

[0038] Step 3: Activate the purified water by taking the nano powder obtained in step 2. The operation process is: add citric acid or acetic acid to the purified water to adjust the pH value of the purified water to 4-5; inject the nano powder into an inert gas for passivation treatment; Mix the passivated nano-powder with acidified purified water, add it into a high-pressure container, and fully soak it to obtain ac...

Embodiment 3

[0042] Step 1, take a total of 5g of glycerin and propylene glycol, 5g of aloe vera gel, and 1g of hyaluronic acid for ultrafine grinding to obtain ultrafine powder, and set aside;

[0043] Step 2: Take 0.5g of hydroxypropyl methylcellulose and divide it into two parts. Take the first part of carbomer to modify the ultrafine powder obtained in step 1. The operation process is to combine hydroxypropyl methylcellulose and After the ultrafine powder is fully mixed, add it to the nano pulverizer, and grind it repeatedly to obtain the nano powder, which is set aside;

[0044] Step 3: Activate the purified water by taking the nano powder obtained in step 2. The operation process is: add citric acid or acetic acid to the purified water to adjust the pH value of the purified water to 4-5; inject the nano powder into an inert gas for passivation treatment; Mix the passivated nano-powder with acidified purified water, add it into a high-pressure container, and fully soak it to obtain ac...

Abstract

The invention discloses a physical contraceptive gel film-forming agent without a spermicide, which comprises the following components in percentage by weight: 1 to 3 percent of chitosan, 0.5 to 3 percent of a thickening agent, 5 to 15 percent of glycerol and propylene glycol, 0.1 to 20 percent of a bactericide, 1 to 3 percent of a nourishing agent and 56 to 92.4 percent of purified water with a pH value of 4 to 5. The physical contraception gel film-forming agent provided by the invention can wrap sperm and shield the sperm so that the sperm cannot pass through the cervical opening in a certain time, thereby achieving the purpose of pure physical contraception, and the contraceptive rate is higher; finally, the sperm is discharged out of the body along with vaginal secretion, and the physical contraception gel film-forming agent has no toxic or side effect on female physiological health; the physical contraception gel film-forming agent does not contain the spermicide, the action timeto the contraceptive gel is wider than that of the traditional contraceptive membrane; the physical contraception gel film-forming agent can prevent and improve the genital tract infection, can improve the defect that the external contraceptive is easy to be infected, and can adjust the pH value of the vagina, thereby achieving the effects of moisturizing, lubricating, improving the elasticity ofthe vagina, reducing the vagina and improving the quality of sexual life.

Description

technical field [0001] The present invention relates to the field of medicine. More specifically, the present invention relates to a spermicide-free physical contraceptive gel film former. Background technique [0002] The need to control population and physical health has made contraception more and more important. Contraception refers to the use of special means to temporarily prevent a woman from becoming pregnant. Common contraceptive methods include: oral contraceptives, rhythm contraceptive methods, extracorporeal ejaculation contraceptive methods, intrauterine device contraceptive methods, surgical contraceptive methods, condoms, and diaphragms. Wherein, the contraceptive film is a kind of contraceptive for external use. In the prior art, the contraceptive film mostly uses nonoxynol as the main component, and polyvinyl alcohol is made of a water-soluble film-forming material. Nonoxynol has the characteristics of fast and efficient spermicide. Knead the drug film in...
