How do you make soap? How to make soap?

Fat (fragrant) soap is a necessity of people's lives. Since the former market, most of them are lumpy products, and their surfaces are very smooth after contact with water, and if they are not careful, they will slip to the ground. Fertilizer (fragrant) soap shared in public places is also unhygienic after being forwarded and used by multiple people.

Foreign research and development of a new type of lightweight soap as thin as paper, simple manufacturing process, low cost, put on the market after the majority of customers welcome.

Directions: Cut tissue paper into the appropriate size and soak it in soap. After soaking, it is pressurized and heated to form.

Depending on the situation, it can also be dried in a dryer. In addition to tissue paper, the impregnated material can also be made of cloth or cord. Its shape, size, thickness can be flexibly decided according to different requirements, such as sheet or roll, etc.

In addition, spices, pigments, etc. can be added appropriately. For easy carrying, it can also be packed in a bag.

When used, soap tablets are placed in water, and when enough water is absorbed, they are rubbed by hand to produce a rich lather, which has the same decontamination ability as the usual solid block soap.

1.Principle Grease and sodium hydroxide are boiled together and hydrolyzed into sodium and glycerin, which are processed and molded into soap.

2.Supplies 150 and 1 300ml beaker, glass stick, alcohol lamp, asbestos net, tripod, lard (or other animal or vegetable fat or oil), Naoh, 95% alcohol, saturated salt water.

3.Operation 1) In a 150ml beaker, hold 6g of lard and 5ml of 95% alcohol, then add 10ml of 40% NaOH solution. Stir with a glass rod to dissolve it (heat over a slight heat if necessary).

2) Place the beaker on an asbestos net (or in a water bath) over low heat, stirring constantly with a glass holder. During the heating process, if the alcohol and water are evaporated and reduced, they should be replenished at any time to maintain the original volume. For this purpose, a mixture of alcohol and water (1 1) 20 ml can be pre-prepared for addition.

3) After heating for about 20min, the saponification reaction is basically complete. If you need to test, you can use a glass rod to take out a few drops of the sample and put it into the test tube, add 5 6ml of distilled water to the test tube, heat and shake. When standing, there is oil separation, indicating that the saponification is incomplete, and the lye can be added dropwise to continue the saponification.

4) Slowly add 20ml of hot distilled water to the saponified viscous liquid and stir to make them miscible. Then slowly pour the viscous liquid into a 150ml hot saturated salt solution, stirring as you go. After standing, the soap is salted out and floats, and the soap can be taken out with a glass rod after all the soap is precipitated and solidified, and the soap is made.

2) If you do not use a water bath, you must use low heat.

3) During the saponification reaction, the original volume of the mixture should be maintained, and the mixture in the beaker should not be boiled dry or splashed outside the beaker. Note: Saponification reaction: grease in.

The method and recipe of soap are as follows:

12 ounces of distilled water, 1 can of vegetable shortening, 6 ounces of lye, 8-8 inches of container.

Step 1: Pour the shortening into the enamel pot and place on the stove to melt. Heat the lye in another enamel pot.

Step 2: Pour cold distilled water in a glass bowl and slowly pour the lye into the water. Stir constantly with a wooden spoon until the mixture is clear.

Step 3: Pour the shortening in another glass bowl and add the above lye and distilled water mixture. Pour in slowly and stir constantly. Make sure that the heat of both liquids can be touched by hand.

Step 4: When the above solution becomes viscous, you can add different additives, spices, oils or herbs and mix well.

Step 5: The next step is to pour the solution into a container and place the mold in a warm and insulated place to keep it for more than 24 hours.

Step 6: Cut the above large soap into the desired pieces and store it in a dry place to dry. They will be ready to use after three weeks. After learning how to make your own lye soap, it's time to try your own home soap.

How to make homemade natural soap.

Step 1: Mix rosemary and lavender leaves and grind them into a powder with a food processor.

Step 2: Bring the water to a boil and pour it into a glass bowl and add 6 tablespoons of the above powder.

Step 3: After 10 minutes, add the rosemary and lavender essential oils to the bowl.

Step 4: Melt the glycerin soap in a saucepan, mix the above solution and stir continuously until smooth.

Step 5: Pour the mixture into the mold and let it sit for at least a month.

Step 6: After a month, remove the soap from the mold. The soap can be wrapped in plastic film and butter paper and stored.

Ingredients of soap: sodium salt R-Co2Na of carboxylic acid, synthetic coloring, synthetic fragrance, preservative, antioxidant, foaming agent, hardener, viscous agent, synthetic surfactant.

The main ingredient of soap, R-CO2NA, (sodium stearate (C17H35COONA)), in which the R group is generally different, is a variety of hydrocarbon groups. r- is a hydrophobic group and a carboxyl group is a hydrophilic group. In hard water, soap and Ca2+, Mg2+, etc., form curd-like substances, fatty acids, calcium salts, etc., which are commonly referred to as "calcium soaps" and become useless descalers.

The addition of a softener to hard water removes the hard water ions of the sedan and allows the soap to work. Medicated soap is mainly made with some disinfectant added to it. Soap adds fragrance to it. Crystal soap contains saponin, which has a particularly strong degreasing power.
