The face wash only cleans dirt and oil from the face and pores. dust. Sweat, which rarely stays on the face, involves waterproof cosmetics, and it is necessary to use makeup remover products ~ Cleansing oils contain less oil, surfactants and ethanol, using the principle of oil-soluble oils, can dissolve dirt and makeup, and surfactants can Emulsify the dissolved dirt and dissolve it in water to clean it to achieve the purpose of removing makeup~, the cleansing oil is relatively greasy, especially in hot summer, it is mainly used for difficult to remove makeup. Cosmetics choose corresponding products, but we also need to choose products that are suitable for our skin conditions, such as sensitive skin and mild makeup remover products~. Amino acid surfactants are added to the real amino acid face wash. You can remember this formula to distinguish a real amino acid face wash: Oil + Acyl + X Amino Acid + X Salt.Dimethyldiisodecylammonium chloride supplier  Typically, active agents in solder pastes include organic acid actives such as succinic acid (succinic acid) diacidsuccinic anhydride (succinic anhydride) dibromosuccinic acid glutaric acid itaconic acid salicylic acid (medical grade ) dodecanoic acid; also surfactants and amine salts halogen active agents. They perform functions such as deoxidation, cleaning of solder surfaces, soldering, spreading, wetting, etc. More than 90% of makeup removers are water, and the active ingredients are a small amount of added polyols and surfactants. Polyol-based makeup removers are mild, but not powerful enough; surfactant-based makeup removers are too strong and have a high chance of irritating the skin. Compared with other dosage forms, it is a tasteless product. The foam in the facial cleanser has different effects depending on the surfactant. For example, the lather of a high-quality face wash should be fine and textured. Rough and loose foam is usually a product with more soap base, less nutrients, and poor detergency and moisturizing effect. Some foreign brands also have a non-foaming facial cleanser, which does not contain a soap base, has a very subtle foam, but has a very strong washing power, and has functions such as balancing oil, moisturizing, and moisturizing. Therefore, it is a misunderstanding to determine the quality of a face wash based on the amount of foam alone. Finally, popularize chemical knowledge: 1. The decontamination ability of amino acid silk soft facial cleanser is related to the number of carbonic acid atoms in the surfactant; 2. Ordinary facial cleanser contains 12 carbon atoms, cardamom contains 14 carbon atoms, and palm contains 16 carbon atoms; 3. The higher the number of carbon atoms Less, the better the foaming effect, the worse the decontamination ability.Didecyldimethylammonium chloride factory  These two ingredients are the standard of amino acid shampoos, amino acid shampoos have flourished in recent years, mainly containing amino acid surfactants, amino acids are very skin-friendly, naturally weakly alkaline, the biggest advantage is to really clean and protect our hair, from the root The above solves the problem, but the price of amino acid shampoo is higher than that of ordinary shampoo. For example, many netizens say that amino acid foam is rich, shampoo is fluffy, foam texture, delicate touch hair is very comfortable. It is a silicone-free surfactant used to reduce static and dynamic surface tension. The additive can reduce the dynamic surface tension of the system, thereby improving the wetting ability of the system, especially during high-speed construction. Suitable for water-based systems. A continuous solid film is formed on the foam layer. The film can effectively prevent the water-soluble absorbing foam of water, moisture, fluorine protein foam fire extinguishing agent. After rising to the surface of the oil, the foam itself contains enough oil. To make it burn, it consists of fluorocarbon surfactants. Composed of fluorine-free surfactants (carbon chlorine surfactants or silicon surfactants) and additives (foam stabilizers, antifreezes, solvents, thickeners, etc.) and water, the fire extinguishers of foam fire extinguishing agents are mainly cooling and suffocating. That is, a continuous foam layer is formed on the surface of the combustion object.D1021 manufacturer  The surface of the combustible is cooled by the mixture of the foam itself and the precipitate, and the combustible is isolated from oxygen and extinguished by the covering of the foam layer, as follows. Studies have shown that biosurfactants are potential substitutes for chemically synthesized surfactants. By 2023, the market value of biosurfactants will reach $2.8 billion. It has attracted much attention in recent years because of the low toxicity of biosurfactants. Properties such as biodegradation help the product meet the European Surfactant Directive requirements. Commonly used surfactants are alkyl succinate sulfonates. FAS ammonium salt or Tween type low HI. B-value active ingredients need to add cationic or zwitterionic surfactants to achieve the purpose of sterilization and softness, so that the carpet can restore its original color and luster after cleaning, soft and elastic, and prolong the time from recontamination.
