Silver ions are silver atoms that lose more than one electron and exist in an ionic state, usually positively charged, such as Ag1+, Ag2+, Ag3+, and the like. Silver ions have an oxidizing effect and are often used for sterilization in daily life. Ions are charged atoms (or groups of atoms), positively charged ions are called cations, and negatively charged ions are called anions. Generally, the ion size is not considered, and it is only considered when it is coordinated; the unit of measurement is angstrom, which is a smaller unit of atomic structure than nanometer. Ions are formed by electron transfer through chemical reactions. Their properties depend on what ions and charge charges are related to the size of the ions, and there is no nano-effect. It is usually present in the form of an aqueous solution. Colorless and transparent, without any solid particles, stable in state. Silver ions are silver in which silver atoms lose more than one electron. It means that silver exists in an ionic state, usually positively charged. Such as Ag+1, Ag2+, Ag3+, and the like. Silver ion pharmaceutical products have been included in the Chinese Pharmacopoeia in the past century, such as silver nitrate solution. Silver ions have different oxidation activities with different valence positions. The +2,+3 silver ions have high oxidizability. The oxidation-reduction potential of Ag+ is determined by voltammetry (±0.798 ev, 25 °C), while Ag2+ has higher oxidation. Reduction potential (± 0.102 ev, 25 ° C). The effectiveness of high-priced silver ions is 300 to 17,000 times that of metallic silver or silver salts. Since the high-valent silver ion has a very high reduction potential, it is also called active silver ion. Therefore, in terms of "silver ion", it is characterized by: 1. Silver ions are positively charged "cations" formed by electron transfer by chemical reactions; 2. The application of silver ions depends on the properties of the ions themselves and the charge price, regardless of the ion size, and there is no nano effect; 3. Silver ions are present in the form of an aqueous solution. Colorless and transparent, without any solid particles; 4, silver ion pharmaceutical products have been included in the National Pharmacopoeia as early as the last century, such as: silver nitrate solution 5, silver ions for its antibacterial, widely used in life, like baby products (Bier Phyll silver ion PESEQ (puzzle) Bottle), children's tableware (bacteria afraid of silver ion sterilization children's tableware). The application of silver ions in history: In fact, it is like the ancient people used silver needles to test whether the wine is poisonous. If it is poisonous, the silver needle will turn black immediately. There are many stories like this in history. Before the birth of Christ, ancient Greece used silverware to preserve drinking water and prevent bacterial growth; In order to keep fresh, the ancient Phoenicians used silver utensils to hold water, wine, vinegar and other liquids during the voyage; Ancient Mediterranean residents put silver coins in wooden buckets to stop the growth of spoilage microorganisms such as bacteria and algae; In 338 BC, when the ancient Macedonians fought in Greece, they covered the wound with silver to accelerate healing; The Chinese emperors and ministers used silver chopsticks to eat; the Middle Ages used silver foil to protect the wounds, and by the time of World War I, the wounds were also sutured with silver thread, which was not easy to infect; Silverware has been found in the pyramids of ancient Egypt; it is recorded that the Droid monks generally use silverware; All over the world, long-term love to use silver tableware, Russian and Swiss families love to use silver filter core to filter water; In the early days of the United States, silver coins were placed in milk cans to keep them fresh; in the space satellites, water was stored in silver cans; Western newborns are baptized, and very dilute silver nitrate is added to the holy water to prevent infection. Silver ion in the field of cosmetics: The significance of using electrolytic silver ions in cosmetics: 1. Fully replace various chemical anti-corrosion additives widely used in the production of cosmetics and personal care products, greatly reducing the damage and adverse effects of anti-corrosion additives on the skin. 2. Make the content of cosmetics and personal care products more fresh and pure, and fully utilize the various functions of nourishing, beauty, moisturizing, whitening and anti-aging of cosmetics and significantly prolong the service life. 3. Promote the healing of skin wounds and increase the repair function of damaged cells. 4. Effectively improve the moisturizing and penetrating effect of cosmetics, which is conducive to the absorption of nutrients by the skin. 5. More importantly, cosmetics and personal care products with silver ion solution have natural active defense against bacteria and directly inhibit bacterial damage to the skin. Many of the symptoms caused by the damage of the skin itself and the mucous membranes of the body can be solved, such as skin allergies, inflammation, indecent body odor, facial sores, dandruff and the like. In short, the wide application of silver ionic liquid in cosmetics will definitely bring revolutionary changes to cosmetics. Healthy cosmetics will become the most intimate partner and assistant of human beings in modern life. Faced with the increasingly complex and harsh ecological and living environment, the threat of unidentified viruses and super bacteria, and the use of silver ionic liquids, the cosmetics will be treated in different ways, methods and skin types and environmental experiences.
