1. Detergent

Handmade soap has a gorgeous name called "natural cleansing active agent". Many handmade soaps contain certain ingredients. , everyone should pay special attention when purchasing. Because among detergents (surfactants) that damage the skin, soap base (soap) is the most serious. Others are detergents made from oils and strong alkali, which are called "synthetic cleansing active agents." Synthetic cleansing active agents are the main culprit in recent years causing discomfort to sensitive skin and making the skin wrinkled and red. Soap is the longest-used surfactant in human history. It is also the type of surfactant that causes the most damage to the stratum corneum of the skin, and soaps cause greater damage to the stratum corneum.

2. pH value

The damage caused by soap to the skin was once thought to be due to its excessive pH value. However, research shows that the pH value does not cause dry and damaged skin. The most important factor is that the skin has strong adaptability to pH value. The damage caused by soap to the stratum corneum of the skin is due to its unique surfactant properties. Therefore, the pH value of handmade soap is lower than that of ordinary soap, which is not the reason why handmade soap is less irritating than soap or toilet soap.

3. Glycerin

Some people will say that more glycerin makes handmade soap milder. After handmade soap undergoes incomplete saponification (the saponification rate is lower than ordinary soap), there is no subsequent glycerin extraction process. , so there is a lot of glycerin in the final product, but unfortunately, the large amount of glycerin that many handmade enthusiasts are proud of is not the reason why handmade soap is milder than soap. Due to its water solubility, glycerin is destined to be washed away during the cleaning process and will not be deposited on the skin. In other words, the improvement effect of glycerin on mildness can only have a weak effect and can even be ignored.

4. Vegetable oils in handmade soaps

The carbon chains in the vegetable oils in handmade soaps are not all long-chain fatty acids such as stearic acid. The short-chain fatty acids formed after neutralization Soap is actually quite irritating to the skin because of its small molecular weight, which makes it easier for it to penetrate deeply into the skin. Different natural oils have different compositions, different short-chain fatty acid contents, and different irritations.

5. Irritation to the skin

Soap itself is highly irritating and will always dissolve some lipids, no matter what method you use. What's more, handmade soaps do not add compound amphoteric surfactants or nonionic surfactants commonly used by formula developers to reduce lipid dissolution and irritation. Some people say that it is not mentioned above that you can replenish lipids such as stearic acid, but you have to think about it: if the lipids in the stratum corneum do not dissolve, wouldn't it be better and gentler? Why wait until they are dissolved to replenish them? So , from a gentle point of view, the editor thinks that washing your face with handmade soap is not good. We cannot use handmade soap as the main daily cleaning product because of its better rinsing feeling, so I still buy facial cleanser and the like honestly. Use cleaning products to wash your face. How long can handmade soap be stored?

How long is the shelf life of a piece of handmade soap? Since handmade soap is made of pure natural plant essence, no chemicals, preservatives or other substances are added to it.

Usually, handmade soap needs to be used within one year after it is made, otherwise it will easily deteriorate and can no longer be used to clean the skin. Can handmade soap remove makeup

Handmade soap cannot replace facial cleanser and makeup remover oil.

First let’s talk about the pros and cons of handmade soap: Handmade soap contains natural glycerin, which has extraordinary moisturizing effect, is very gentle to the skin, and is non-irritating. The foam is fine and rich. In addition to its amazing cleaning power, it will not damage the skin's stratum corneum at all. This is because the glycerin contained in it can form a protective film while cleaning dirt to protect the skin. Once the skin's stratum corneum ages, it will lose important water. The loss of water is one of the reasons why the skin becomes dry and wrinkles appear.

However, because they cannot be mechanized in large quantities, and have a short shelf life and high cost, major brand-name skin care products have no place for them.

The disadvantages are also obvious: short shelf life. Since no unnecessary preservatives are added, the shelf life is short. This can be regarded as a "beautiful regret".

Potential harm to the skin. The alkali agent (sodium hydroxide) used to saponify oil and fat itself is very damaging to the skin, and because there is no sufficient purification process to remove the residual alkali, More likely to cause irritation to skin. At the same time, most of the handmade soaps sold on the Internet today are handmade in individual workshops, and there is no relevant quality control from the source of raw materials to the production environment. Some handmade soaps even directly add ingredients such as fruit juice, vegetable juice, and yogurt. Claimed to be "natural", in fact, these simply added ingredients are very prone to unstable chemical reactions or the breeding of microorganisms, which can have a negative impact on the skin. If you want to reduce the generation of microorganisms without adding preservatives, you must increase its alkalinity. The stronger the alkalinity, the greater the damage to the skin.
