Avoid making soap with delicious water and use stainless steel utensils with caution.
Generally speaking, distilled water is the best water for making handmade soap. Then, can't you use "good water" such as mineral water and spring water? The answer is: it is best not to use it.
Mineral water makes people feel delicious because it contains trace mineral components, including copper, manganese, iron, chromium and other metals. Even if the amount is small, it is enough as a catalyst to promote the oxidation of oil. If this kind of water is used as soap, the finished soap is relatively easy to oxidize.
Stainless steel is an alloy of iron, chromium and nickel. When making soap, if stainless steel pot or eggbeater is used, these metals will dissolve in a strong alkali environment.
Similarly, the finished soap is easy to oxidize. If you want to use it, you should find ways to reduce the risk of oxidation, try not to scrape with tools, or use plastic containers directly.
Avoid soaping your body with recycled oil. It is often said that making soap with household recycled oil can not only reduce garbage, but also make soap that is environmentally friendly and gentle to the skin.
Studies have shown that the recovered oil is oxidized after use, which contains lipid peroxide. If smeared on the skin, it is easy to cause inflammation or pigmentation. In addition, most of the raw materials for household oil recovery are cauliflower oil (mustard oil), soybean oil, corn oil and peanut oil. These oils are nutrient-rich soft oil products, which are not easy to solidify, dissolve quickly after meeting water, and are easy to soften and rot.
So it's better to make the recycled oil soap into hand sanitizer to wash dishes or clean the bathroom, so there is no problem. Transparent soap is not gentle with the skin.
Transparent soap gives people a high-level impression, because soap-based soaps are mostly transparent, and the soap-based soaps produced by factories have a bad soaping feeling. In fact, you can also be transparent soap at home. You can add sugar and alcohol to palm oil, coconut oil and sesame oil to make transparent soap.
However, in order to make soap transparent, the grease that can be used is limited, so the finished soap does not perform well in decontamination and foaming power, and it is not good for the skin. Since everyone wants to make soap, the sense of use should be more important than the outside. Compared with the cold soap made of other oil formulas, it is better not to use transparent soap's.
2. Explain the knowledge of handmade soap
Sodium stearate: a heat stabilizer for polyethylene, which has excellent lubricity and processability. It can be used in hard products together with alkaline lead salt and lead soap to improve the gelation speed. Used to control foam during rinsing. (Sodium stearate is the main component of soap)
Sodium palmitate:' is the main component of surfactant and oil-soluble emulsifier soap.
Sodium laurate: It is also the basic ingredient of soap.
Soap base: the basic raw material for making soap, or soap made by mixing oil with sodium hydroxide (alkali) and water, without adding any additives, can be called "soap base".
Fatty alcohol polyoxyethylene ether sodium sulfate anionic surfactant, easily soluble in water, has excellent decontamination, emulsification, foaming and hard water resistance, and mild washing performance will not damage the skin.
Sorbitol: Used as humectant, flexibilizer, humidity regulator, softener, adhesive, complexing agent, plasticizer, lubricant and decomposer.
Propylene glycol: Soap can be used as wetting agent together with glycerol or sorbitol.
Sodium chloride: Edible, industrial, medical, extractable salt.
Spice: add flavor.
3. Precautions for handmade soap
Choosing a soap base with high glycerol purity, the key to a good handmade soap is the glycerol content of the soap base used. Natural glycerin is a humectant. Using handmade soap rich in natural glycerin, the skin is like moisturizing lotion, clean but not dry, moist but not greasy.
Therefore, when making transparent soap, it is often necessary to add glycerol to make it together. The shelf life of handmade soap with fresh additives will be shortened. Generally, handmade soap can be kept for about two years, but if fresh additives are added, the shelf life will be shortened and it can be kept for about half a year.
If you smell the oil consumption of handmade soap, it means it has expired. So if you only use it for yourself, it is recommended to make only a small amount at a time, which will be fresher.
Use hand soap with caution for sensitive skin. Handmade soap is very beautiful. Essential oil handmade soap has a special fragrance. It is still a good scenery at home, so DIY is still very good at ordinary times. But if you have sensitive skin, don't take your face to test the quality of handmade soap, because handmade soap is alkaline because it adds soap base; Sensitive skin, if used, can easily cause skin allergy or make the skin worse and worse. For people with sensitive skin, it is recommended to do a skin test on the arm or behind the ear before use.
When in use, you can wet the soap, gently knead it with your hands, and apply it after foaming. It is appropriate for soap to stay on the face for 30 seconds, so that the sebum membrane can be restored to a balanced state in the shortest time. After using the soap, put it in a breathable soap box or container, try to keep the soap dry, and never soak it in water, which will shorten the use times.
Even if it is a very natural material, sensitivity test should be done first. In the name of environmental protection, the ancient handmade soap that once withdrew from people's dressing tables is back. As a new beauty fashion, it has set off a new fashion in the network.
However, behind this so-called more natural and safer "handmade soap beauty", is it a new discovery of ancient beauty recipes or a beautiful lie? Do people misread the efficacy of handmade soap? The "handmade soap beauty" network is hot. Speaking of handmade soap maintenance, maybe you have already tried it, or you are preparing to move and have grown up for a long time. I don't know when, handmade soap, which has long since withdrawn from the maintenance field, began to return to people's sight.
This time, it is no longer just a traditional hand soap, but a new beauty trend as a "skin care product". It is said to originate from the traditional European craft, and no chemical components are added in the production process. After use, it will not only cause hidden dangers to the skin like those skin care products containing chemical components in the market, but also cause 100% pollution to the skin and the environment. These handmade soaps produced by cold-making methods quickly became popular on the Internet under the banner of environmental protection.
Most handmade soaps sold online are made by individual workshops. Because of the different functional ingredients added, these handmade soaps are also derived from various skin types and skin needs.
Nowadays, the maintenance field of handmade soap has long been not limited to the face, and even extended to shampoo and bath. Attracted by its green and free skin care propaganda, many people have begun to become fans of "handmade soap beauty".
Because the process of making handmade soap itself is full of DIY colors, many people even start making it themselves. However, behind this seemingly beautiful trend of handmade soap maintenance, it may be a seemingly beautiful lie.
Myth 1: Handmade soap is a skin care product, not ordinary soap. In many "hot" posts on online forums about handmade soap beauty, it is mentioned that handmade soap is a skin care product rather than a traditional soap. In their view, because handmade soap is made by cold method, it can produce rich moisturizing ingredient natural glycerin, and it can also retain the nutritional value of various natural plant essential oils, medicinal materials, ingredients and other additives beneficial to the skin during the making process. Therefore, handmade soap is not ordinary soap, but "skin care products with natural ingredients".
However, it is not difficult to find that this statement is not reliable by carefully studying the production methods of handmade soap and ordinary soap. In fact, soap made in industry and handmade soap made by cold method are both saponification reactions of oil and alkali (usually sodium hydroxide). Although chemically synthesized surfactants or emulsifiers are added to the soap made in industry to reduce the sense of use, it is no different from the soap components mainly used for cleaning.
The so-called handmade soap contains natural glycerin, which is actually just a by-product of saponification reaction. Adding all kinds of so-called skin-beautifying additives to the cold method can't change the fact that handmade soap is still a kind of soap made by an ancient method, because after all, handmade soap is still used for cleaning, and its main functional component is soap.
Myth 2: handmade soap is more environmentally friendly and safer. The most attractive reason why "handmade soap beauty" is popular again on the Internet is its slogan of "greener and safer", and some people even define it as "the retro and return of natural skin care". In their view, because the surfactant fatty acid contained in handmade soap once diluted by water or neutralized by acid has the characteristics of releasing all the dirt caught, it is undoubtedly more environmentally friendly than synthetic cleaners.
Myth 3: Handmade soap has magical skin care effect. "After long-term use, you will find that your skin is better, your allergies are less, your dandruff cracks are gone, and your skin is elastic again …" Someone described the magical skin care effect of handmade soap. It seems that in order to prove its omnipotent skin beautifying effect, today's handmade soaps have also developed functions and types covering almost all kinds of skin conditions and skin problems.
The price of 50g handmade soap with "luxury" functional ingredients is even 50~ 100 yuan. However, many handmade soap manufacturers also emphasize that the nutritional value of various natural plant essential oils, medicinal materials and ingredients can be preserved to a greater extent because they are not subjected to high temperature in the production process, and these precious ingredients can penetrate into the skin through pores during use, thus achieving the effect of cleaning and maintaining 1+ 1 > 2.
At the same time, the natural glycerin produced by saponification reaction can also form a natural protective film on the skin. However, experts told me.
4. Who can help me introduce some knowledge about handmade soap?
The normal PH value of human body is weakly alkaline at 7.35 ~ 7.4, but some sebaceous glands are vigorous and secrete weakly acidic oil. Handmade soap has a strong alkaline degreasing effect and has no good natural protection effect on alkaline substances. Because the normal pH value of human body is weakly alkaline, and there is a buffer to neutralize acidic substances, handmade soap and weakly acidic facial cleanser are better for the skin than weakly acidic facial cleanser.
From the cleaning point of view, handmade soap is better but larger. If you need to remove oil from oil wells and small oil wells, you can choose sulfur soap, but sulfur soap has a smell of sulfur. If you are a girl, it may be hard to accept, but the advantage of sulfur soap is that it has little damage to the skin, can sterilize and prevent some skin diseases.
Sang Maliana's is good, it's a brand from Taiwan Province province, and it's not expensive.
5. How can handmade soap be harder?
1. Add stearic acid
It's best to add a little less, because too much will lead to a lot of small white pieces in the handmade soap. Therefore, it is necessary to control the dosage when using.
Reduce water quantity
Reducing the amount of water is the most effective method, and at the same time it is not afraid of too soft oil and too soft soap. However, if the amount of water is too small, it is still prone to small white flakes, so the amount of water should be controlled and not reduced too much.
3. Appropriately increase the proportion of coconut oil.
In the early days, many people thought that the proportion of coconut oil above 20% was suitable for oily skin, but this would lead to the problem that the soap made was always too soft or felt almost the same when washed out. The proportion of coconut oil in shampoo or cleaning soap is as high as 40%, but it will not be too dry when washing. Therefore, when making handmade soap, we should look at the overall proportion of oil, not just the cleaning power of coconut oil. Therefore, we might as well try to increase the proportion of coconut oil appropriately.
4. Replace soft palm oil with a small amount of hard palm oil.
Palm oil has always been one of the indispensable oils for making soap. In addition to its low price, the book also emphasizes that palm oil is "neutral" and will not affect the characteristics of other oils and fats. Although the foam is small, it is hard enough, so it will be used in large quantities. However, palm oil accounts for more than 30%, and soap usually has poor washing feeling and hardness, so a small amount of hard palm oil can be used to increase the hardness.
