In this year, without the use of handmade soap, it seems that it does not flow into the stream, and all kinds of god soaps are being stirred up. For example, it is true that it retains a lot of natural beneficial ingredients, is rich in moisturizing factors, is gentler on the skin, etc. Is it really good to wash your face with handmade soap? What is the difference between handmade soap and industrial soap? Let's discuss this topic today.
Q1: What is the difference between the ingredients of handmade soap and industrial soap?
First of all, you have to know that in the production process, handmade soap and industrial soap are sodium saponified by fatty acid and sodium hydroxide, but there are many kinds of fatty acids, which can be divided into at least saturated fatty acids and unsaturated. There are two types of fatty acids, the former such as lard and butter, and the latter with olive oil, coconut oil and so on. It is the fatty acid sodium that plays a role in washing off the stains in soap.
Therefore, the quality of sodium fatty acid is directly related to the decontamination ability of soap. In actual production, the formula of soap (soap) is often very complicated, and the raw materials used are a mixture of several or even a dozen fatty acids in order to obtain a better decontamination effect and skin contact feeling.
Q2: What is the difference between handmade cold soap and industrial soap?
A typical preparation method of hand-cooled soap: first weigh out a certain amount of base oil (ie fatty acid ester), sodium hydroxide and water; then slowly dissolve sodium hydroxide in water and stir evenly; heat the base oil to After 60 ° C, slowly pour into the above aqueous sodium hydroxide solution, while stirring constantly, stir for 15-20 minutes after the completion of the pouring, and keep the temperature between 40-50 ° C throughout the stirring process. Subsequently, the paste is poured into a mold and naturally cooled, placed in a cool and ventilated place, and can be demolded after 4-6 weeks.
The basic process of typical industrial soap manufacturing: adding fatty acid ester, aqueous sodium hydroxide solution to the reaction kettle, heating with steam until the water boils, and reacting under strong mechanical stirring for several tens of minutes to one hour, the resulting product is treated with brine. Washing, layering, drying and cooling to obtain a soap base (ie, a piece of soap). After drying, compressing and melting the soap base, adding spices and other ingredients (such as disinfectant, moisturizer, etc.), and then pouring The mold is released from the mold and polished to obtain soap.
Q3: Is the handmade soap alkaline lower?
Everyone thinks that the handmade soap is milder. In fact, the manual soap is slower in the process of making the handmade soap. This means that the reaction speed of the raw material is slow. After the final solidification, some of the sodium hydroxide may not be reacted. Sexual substances are very harmful to skin damage. Therefore, handmade soap is not necessarily milder than industrial soap!
The circulatory system is a continuous system of closed ducts in all parts of the body, including the cardiovascular system and the lymphatic system.Blood circulates in the cardiovascular system.Lymphatic fluid flows through the lymphatic system.The lymphatic system can also be thought of as an auxiliary part of the venous system because it flows centripetally along a series of lymphatic ducts and eventually drains into the veins.
This model is suitable to medical institutions to explain human anatonv, such as thoracic surgery and internal medicine curriculum as visual aids, can be used for classroom health demonstrations and anatomy teaching aids and can also be used for children's educational toys.
