So why do you want to add a surfactant when making detergents? In fact, the surfactant is a chemical synthetic agent that can emulsify the dirt, remove the dirt on the clothes, but if it is not clean, it will remain in the clothes, and people have long contact with surfactant, which will affect Health, especially the harm to the elderly and children. When cleaning clothes, if the foam is much, the higher the chemical composition in the detergent, the greater the corrosion of the clothes, the higher the stimulation of the human skin, the more the foam, the better the detergent. At present, there is not much cleaner in the market, which is generally composite with other surfactants, and the washing feel will be better. For the skin dried, there is basically no big problem as long as it is not excessive. When the surfactant is completely dissolved in aqueous solution, it is generally arranged on the foam gas and the liquid interface to stabilize the foam. When the surfactant is in an insoluble or sufficient state, the particles are dispersed in a solution and accumulate on the foam, foam as an antifoam. 2. The dispersed state and surface properties of the compatible defoamer in the solution are significantly affected by other defoaming properties in the solution in the foam system. The antifoaming agent should have an appropriate dispersion and excessive or too small particle size, which will affect its defoaming activity. 1. Dispersibility of the antifoaming agent in the solution. Cleanser cleaning ingredients are generally divided into two categories: the first category is a soap-containing saponified formulation; the second class is a formulation of the main component of the surfactant, and is not soapped. Second, I want to add that if the makeup product contains a surfactant, even the core of the removering product is to remove cosmetics or dirt with surfactants, I don't recommend that you do every day, especially when you don't make makeup. The principle of makeup remover: There are also many people called makeup, refreshing, transparent, gum, viscous. The removing mixture is molder, and the surfactant in its ingredient is nonionic, and the ability to dissolve ordinary makeup is also strong than the anionic surfactant. Amino acid surfactants are amino acids (such as glutamate, glycine, etc.) salts (such as glutamate, glycine, and tetraolamine salts). Weak gum or palm oil). The pH of the weak acidic amino acid surfactant is close to the human skin. In addition, amino acids are the basic substance of proteins, so it is gentle, skin-friendly, sensitive. Traditional facial cleanser is very exciting to the skin because it has high alkaline. Amino acid washing soya uses weak acidic amino acid interface active agents, mild skin, and small irritation. Children can use it. The strong alkali liquid is a traditional effective method for removing grease. It reacts with a strong base to the plant oil to form a saponide dissolved in water to achieve the purpose of removing grease. The pure strong alkali can only be saponized to remove the vegetable oil without removing mineral oil. Therefore, people are typically a sulfonic acid anionic active agent, typically a sulfonic acid anionic active agent, and the emulsion of the surfactant is used to remove mineral oil. The strong alkali liquid is high, typically 80 ° C. Commonly used strong base liquid processes are as follows: soaking treatment temperature>2-Hydroxyethyl octadecanoate supplier ethylene stearate manufacturer  80 ° C, treatment time is 5 to 20 minutes, can be sprayed. Washing milk is a liquid product consisting of an oil phase, aqueous phase, surfactant, a moisturizer, nutrients, and the like. Among them, the cream washed milk contains oil phase ingredients, suitable for dry skin; crystal transparent products do not contain oil phase ingredients, such as formula conditioning, which can meet the use of most consumers. Surfactants in the washing milk have five kinds of moist, dispersed, foaming, decontamination, emulsification, and is the main active substance of facial cleanser. Further, according to the similar dissolution principle, during the washing process, the oil phase can dissolve the surface oil-soluble fatty and excess oil; the water phase dissolves the surface water soluble sweat. Organic compounds such as silicone oil are soaked in the surfactant foam and extend into the respective directions, so that the foam continues to be thinned, disrupts the directional molecule adsorption layer formed by the gas-liquid surface (interface) until the foam is broken. In the past, many printing and dyeing companies did not understand the dosage and performance of the foaming agent when using defoamer, so the fabric surface was covered with an irregular shape without several cylinders.Ethylene glycol monostearate factory  When I first met this phenomenon, I didn't know where the super oil came from, because the oil (what color, what color) attached to the fabric surface very bright, touch it into the fabric. Ether foaming agents are alcohol and dirt, irregular, color block, and oil sticky on the fabric. Therefore, while eliminating the foam, there are also many unfavorable factors and negative impacts, or even cause economic losses.
