Suffering pain and itching,mugwort and orange peel bath balls help you

Description: As the weather changes, many people's skin will feel uncomfortable, such as dry, cracked, peeling and itchy. And at this time, the old people will choose some Chinese herbs to boil water for us to bathe. The bath will make us feel very comfortable. But many people consider it is troublesome. Therefore, we wanted to make fashionable, useful and convenient bath balls that can moisturize and stop itching. Besides, we thought of the mugwort grass in the countryside when we were children. It has a special fragrance and antipruritic and the effect of thinning tendons and activating blood. In addition, we found that the pericarp oil capsule is rich in moisturizing, anti-inflammatory and antiseptic essential oil. We began to try the experiment of extracting essential oil from wormwood and pericarp. After many trials and experiments, we found that microwave solvent method was very convenient and efficient. Finally, we put the extracted mugwort and orange peel essential oil into the bath ball fo

As the weather changes, many people's skin will feel uncomfortable, such as dry, cracked, peeling and itchy. And at this time, the old people will choose some Chinese herbs to boil water for us to bathe. But many people consider it is troublesome.And there are still many problems with the bath balls on the market:some brands contain harmful or other substances that can cause allergies,unpleasant strong smell or greasy bath balls or uncomfortable usage and after soaking, it will cause itch on the skin. Therefore, we wanted to make fashionable, useful and convenient bath balls that can moisturize and stop itching. First of all, let's talk about our innovation points. First,unique formula, add its own extracted essential oil and peel essential oil in the bath. Second,turn waste into treasure, extract essential oil with moisturizing, anti-inflammatory and antibacterial from waste peel. The essential oil with antipruritic, dispelling dampness and activating qi and blood circulation was extracted from Artemisia argyi. Third,extracting peel essential oil and Artemisia argyi essential oil by microwave + solvent. Fourth,no extra preservatives , the peel contains limonene which has a certain antiseptic effect. Fifth,suitable for home-made, materials can be purchased in supermarkets. Next,I will introduce the raw material of our bath balls. Pericarp,they are rich in vitamins C 、vitamins P 、 limonene and other nutrients can maintain beautiful skin. Grapefruit is more healthy than flavor. And the citric acid in peel is a natural preservative, so our products are not added with preservatives, so we can use them safely. Mugwort,it is a warm, bitter, non-toxic medicine.It has the effect of restore yang, regulating qi and blood, removing dampness and cold to stop itching, and is often used in acupuncture and moxibustion, so it is also called "medical grass ". Backing soda and citric acid,they are the main raw materials of bath balls. The bath ball dissolves as soon as it is put into the water. Its principle is that baking soda and citric acid react with water and there is carbon dioxide so there will be bubbles coming out. Corn starch,the reason that bath balls can be used as adhesive. I guess you'd like to know how to extract the essential oil and how this bath balls are made so let me tell you now. About extracting essential oil, we have tried many ways,such as distillation,solvent extraction and pressing,but we found microwave solvent method which was the quickest way in the end. Because microwave can quickly convert into heat energy and make the temperature inside the cell rise rapidly. When the pressure inside the cell exceeds the capacity of the cell, the cell ruptures and the active component flows out of the cell. Then the solvent method is used. The method has several key steps as follows: firstly, prepare some mugwort or orange peel (wash, shred, put in a beaker). Secondly,pour in anhydrous ethanol until no herb. Thirdly, sealing the film for two days. Finally, separate the soaking herb and anhydrous ethanol in the beaker into the device. The boiling point of ethanol is 78.4°C, the boiling point of essential oil is 247°C,the boiling point of anhydrous ethanol is less than that of Artemisia argyi, so anhydrous ethanol is steamed out and the essential oil of Artemisia argyi is left in the original bottle. Besides,I will talk about how to make bath balls. The first step is to get 50g baking soda,25g citric acid, 25g corn starch and then mix them together. Secondly, add 20 drops of essential oil,20 drops of essential oil peel,a small amount of pigment and then stir well again. Thirdly, add a small amount of water, continue stirring until the powder is completely dyed and pressed to form a block. Fourthly, place it for two days to volatilize water.It can be used after demoulding. However,we have to be careful about the amount of water added (probably 10 ml), once the amount of water will automatically grow. We looked for experimen
