1. Advantages Glycerin composition The chemical principle of making handmade soap is: ester (oil) + sodium hydroxide = soap + glycerin. Glycerin is an indispensable moisturizing ingredient in maintenance products and cosmetics, and 25% glycerin is naturally produced during the saponification process of manual soap. Most of the soap on the market in saponification, the glycerin produced by saponification is extracted for cosmetic purposes, without glycerin soap, easy to dry the skin after washing. The handmade soap contains natural glycerin, which has an extraordinary moisturizing effect, and is very gentle and non-irritating to the skin. The foam is delicate and rich, in addition to having amazing cleaning power, it will not destroy the cuticle of the skin, because the glycerin contained in it can clean the dirt at the same time, forming a protective film to protect the skin. Once the cuticle of the skin is aging, it will cause the loss of important water, and the loss of water is one of the reasons why the skin is dry and wrinkled. There is no secret formula for handmade soap. Make soap with your heart and speak with quality. Handmade soap is not just a bar of soap, it is a daily skin care product. Long-term use, you will find that some of the previous skin problems have been greatly improved, less allergic reactions, less dander, increased elasticity and so on. Europeans discovered the benefits of cold-made soap early on, and it was all the rage. But because they can not be mass-mechanized production, and the preservation period is short, the cost is high, the major brand-name skin care products have no place for them. Skin care Because there is no need for high temperature heating in the production process, the natural vitamins and nutrients contained in vegetable oil and other additives are preserved to the maximum extent, so it is the best skin care product. We know that by eating a variety of foods to increase their nutrition, the skin also needs to absorb nutrients. Maintenance in the bath is the fastest and most effective way. When the pores of the whole body are relaxed, use manual soap to wipe the whole body, so that the skin can absorb and relax. After bathing, the skin seems to have been wiped with a layer of moisturizing cream, smooth and not tight, and the feeling is only known to those who have used it.
But these benefits of handmade soaps have been questioned. Users must be psychologically prepared not to trust the propaganda of handmade soap merchants too much.
Protect the environment
The handmade soap is rich in glycerin needed by the skin, in addition to washing power, moisturizing the skin, but also will not cause the burden of the skin. Moreover, it will not cause pollution to the environment. Unlike chemical cleaners, handmade soaps are broken down by bacteria into water and carbon dioxide about 24 hours after contact with water. Therefore, even if it flows into the river or the sea, it will not cause environmental pollution, nor will it pose a threat to Marine life. The use of handmade soap is not only good for your skin, but also environmentally friendly, killing two birds with one stone. Therefore, in this era of emphasis on green environmental protection, handmade soap has become a fashion and is greatly popular. 2. Disadvantages Short shelf life Shorter shelf life because no extra preservatives are added. This is a "beautiful regret." Damage the skin Making handmade soap must need alkaline substances, ancient people use wood ash potassium carbonate (aqueous solution is alkaline), modern people use electrolytic sodium hydroxide produced by saturated sodium chloride aqueous solution. Sodium hydroxide is a strong base, which can harm the skin, but after saponification with oil, it is no longer sodium hydroxide (note that there is usually a certain amount of sodium hydroxide left after the reaction), but soap and glycerin. In order for sodium hydroxide to be completely saponified, the manual soap must be left for one to two months after making. However, in fact, due to the limitations of the manufacturing process, manual soap often cannot guarantee that the sodium hydroxide reaction is as complete as possible, and even if it is left for 1-2 months, because it is called solid at this time, the reaction rate is very low, and the contribution to reducing NaOH is not large. Therefore, it is often not guaranteed to be as harmless to the skin as advertised. The alkali agent (sodium hydroxide) used for saponification reaction with oil is itself more damaging to the skin, and because there is no sufficient purification process to remove residual alkali, it is more likely to cause irritation to the skin. At the same time, most of the handmade soaps sold on the Internet are handmade by individuals, and the quality control from the source of raw materials to the production environment cannot be carried out. Some handmade soaps even directly add juice, vegetable juice, yogurt and other ingredients to advertise "natural". In fact, these simple added ingredients are very easy to cause chemical reactions or breeding microorganisms due to instability. Which can have a bad effect on the skin. If you want to reduce the generation of microorganisms without adding preservatives, it is necessary to improve its own alkalinity, and the stronger the alkalinity, the greater the damage to the skin.
Men's handmade soap frequently asked questions and answers
1. Why do handmade soaps have water beads? Cold soap in the production process will produce 20-25% glycerin, plus vegetable oil originally contains a lot of precious moisturizing ingredients, soap will automatically lock the water in the surrounding air, so the condensation of the soap surface drops, the use of cold soap does not have any impact, just wipe off. 2. Is it allergic to use? There are individual people who use cold soap after the skin will appear dry and rough, small acne and other similar to the phenomenon of cosmetic allergy, called "improvement phenomenon". Its true cause is due to excessive sodium hydroxide, the skin caused by irritation, if this phenomenon, should be immediately discontinued, and medical treatment. 3. What do colors and fragrances represent? The color added to the soap can be natural or chemically synthesized. Although the color of chemical synthesis is rich, it is not easy to fade, but long-term use will damage the skin. For the sake of the skin, use some natural colors, such as herbal tea, green algae, natural mineral mud, Chinese herbs, green tea powder, carrot juice, cocoa powder, etc., to make the soap more fragrant. In order to combine soap with aromatherapy, some soaps use pure plant essential oils to add flavor to the soap. However, since no industrial synthetic flavor is added, the retention time and intensity of the flavor will vary. As we all know, essential oils are volatile. 4. How to guarantee the quality? Because the manual soap does not add chemical stabilizers and preservatives, the preservation time of the soap is much shorter than that of the industrial soap. Under normal circumstances, soap soap can be used within one year after making. In addition, the life of handmade soap with fresh additives will be shortened, and handmade soap can generally be stored for about two years, but if fresh additives are added, the period will be shortened, and it can be stored for about 6 months. If you smell handmade soap with fuel consumption, it means expired. Therefore, if you only use it yourself, it is recommended that only the amount of production should not be too large at a time, and it will be relatively fresh. Cold plant soap contains many natural ingredients and not involved in saponification of the moisturizing oil, so usually to store soap in a cool and dry place, soap in the moisturizing ingredients can be fresh. Soaps that are not needed for a while can be kept in the refrigerator, preferably for no more than a year. Use a well permeable container to avoid water accumulation. After exposure to water, handmade soap is usually easier to soften than common soap on the market, so after use, please place the handmade soap on the soap tray that can filter water. Use sponges when using, or rub bubbles on your hands first and then spread on your body, try not to directly use handmade soap on your body. Change the way of use, will use handmade soap more durable.
