Composition of shower gel
Adidas, Lingshi and Shufujia are suitable for neutral skin, and Derson, Bee Flower, Kerou, Dove, Johnson & Johnson, Huirun Moisturizing and Sensitive Muscle can also be used.
The shower gel is mainly composed of water, surfactant, foam stabilizer, essence, thickener, chelating agent and preservative.
Surfactant refers to a substance that can obviously change the interface state of the solution system by adding a small amount. It has fixed hydrophilic and lipophilic groups and is oriented on the surface energy of the solution. Mainly plays the role of cleaning, foaming and emulsification. The common shower gel in the market generally contains a lot of surfactants, such as sodium lauryl polyether sulfate, cocamidopropyl betaine, etc., in order to play a better cleaning effect.
Surfactants such as SLS (sodium dodecyl sulfate), SLES (and sodium dodecyl polyether sulfate) are the most common components of shower gel in the market, which are cheap and have good cleaning effect.
However, friends with sensitive muscles should try not to buy shower gel containing these two ingredients, which is easy to be allergic. You can choose a shower gel with amphoteric surfactants such as cocoamidopropyl betaine as the main ingredient, which has less irritation, mild performance and fine and stable foam.
Foam film stabilizer refers to a substance that can reduce the surface tension of polyurethane raw material mixture, which can prevent the thermodynamic instability of foam from rising to maturity and play the role of stable, fine and uniform cells. For example, PPG- 10 glycerol ether.
The essence is to make the shower gel smell good, and the better essence is the natural perfume extracted from plants, such as patchouli essential oil.
Thickener is a substance that can increase the viscosity of latex and liquid, and it is also called paste when used in food. Thickener can improve the viscosity of the system, keep the system in a uniform and stable suspended or turbid state, or form a gel; Most thickeners also have emulsifying effect. It can be divided into natural and synthetic categories. Natural starch, gelatin, agar, etc. Synthesis of sodium chloride.
The function of chelating agent is to chelate with heavy metal ions to form stable water-soluble complexes, thus passivating heavy metal ions. The molecule of this compound contains an electron donor that can coordinate with heavy metal ions, so it has a series of special functions such as softening, descaling, rust prevention, stability and synergy. Such as disodium EDTA and tetrasodium EDTA.
Seeing the word preservative, preservatives do not conflict. Bath gel contains preservatives more or less. Because many components of shower gel are extracted from organic raw materials, preservatives can maintain their activity and efficacy stability for a certain period of time.
In addition, lipophilic moisturizing ingredients, such as vaseline oil, vegetable oil or shea butter, will be added to the moisturizing shower gel, which can not only clean the skin, but also leave moisturizing ingredients. Students with dry skin or sensitive muscles can learn about it.
Action mechanism of shower gel
Shower gel can clean and moisturize when taking a bath, mainly because of the two stages of cleaning and washing.
In the cleaning stage, high-concentration shower gel and low-concentration synthetic detergent combine with oil-soluble dirt and can be removed from the skin at any time.
In the washing stage, the detergent concentration is low and the water concentration is high, and the dissolved oil-soluble dirt and water-soluble dirt are washed off the body surface to complete the washing. When the concentration of water is high, the moisturizing ingredients will be deposited on the body in the form of a thin film, which is the principle that some shower gels can moisturize.
It is best to use a shower gel with a large surface area net polyethylene bundle (such as "bath ball" and "flower ball"). Bath balls destroy the emulsion of shower gel cleaner by introducing rich water and air. This makes the shower gel produce a lot of foam, so that it can clean the whole body with only one dollar coin.
