(1) During the machining process, due to the requirements of the processing (such as cooling, lubrication, abrasive, surface treatment, heat treatment, etc.). There are various oils on the metal. Most of these oils are mineral oils, including animals and vegetable oils, emulsion, polishing paste, abrasive cream and a variety of salts. This ingredient is relatively simple, and the time in the metal surface is relatively short, the adhesion is not strong, and it is easy to fall off. Therefore, the normal temperature cleaner for metal-free corrosion is selected, and the requirements for other indicators of the cleaning agent are not high. The component of the cleaning agent is selected, and the aliphatic hydrophobic substrate surfactant is mostly used in animal and plant oil. The organized hydrophobic base surfactant is mostly used in mineral oil. Balance skin isastroam investment to add main ingredients of main foam, surfactants (such as sodium sulfate, sodium lauryl polyether sodium sulfate, amino acid system, soap based class, etc.Brij L23 supplier ), moisturizer (glycerol, etc.), ingredients Some ingredients with anti-allergic effects (such as anti-corrosion essence, etc.). When the reservation of the skin is cleaned, apply the foam on the face, slightly, but ineffective, so as not to deepen the eyeliner and the gods The entire face is filled with the neutral finger and the unnamed finger, then wipe with a soothing foam and other ingredients. When it is excessively cleans and rub, the foam and lipid substances will be lost, thereby weakening the effects of the skin's own barrier effect, causing great injuries. Choosing a suitable dispersant is the focus of study in recent years, surfactants are the most commonly used dispersing agent. In the surfactant, the more non-hydrophilic ion groups, the better the hydrophilic group increases the water solubility of the hydrophilic group, reducing the adsorption of the solid surface, particularly on the surface active agent and solid surface. The interaction is weak. But in fact, it is difficult to judge whether it is a normal factory product. It can only be said that it is still suitable or not suitable. In addition, the main reason for affecting the foaming capacity of cleansing products is the selection of surfactants. The foaming ability of the product is more important to affect your feelings.Fatty alcohol polyoxyethylene ether MOA series manufacturer  The process of removing dirt involves the following aspects: (1) Wetting of solid surface and contraction of liquid soil; (2) surfactant dissolution, emulsification, and dispersion of dirt; (3) mixed phase (liquid / liquid, solid / Liquid, gas / liquid dispersion system. During the cleaning process, the soil separated from the solid surface is still possible to deposit into a solid surface again, particularly during multi-cycle cleaning. Therefore, the detergent must have good resistance to sedimentation capacity. Briefly, the surfactant acts as the main raw material of the washing product, and the cleaning effect is performed by removing the dirt and metabolites (including oil and other ingredients) of the skin. Excessive skin cleaning, regardless of the type of surfactant, weaken the barrier structure of the skin surface, and damage the skin's barrier function. Surfactants are often maintained in a strong acid and a strong base solution due to its excellent chemical stability. Since the increase in solubility in strong acid and strong alkali media, some surface activity of some fluoroprofluorogenic agents is higher than that of the aqueous solution (due to solubility limitation, the surface activity of the fluorocarbon surfactant in the aqueous solution is poor). Today, weak acidic cleaning products mainly based on amino acid surfactants are gradually become the mainstream of the market. The main raw material of the amino acid surfactant formulation system is glutamic acid and glycine.Polyoxyl lauryl ether factory  The pH of such products is typically 6 to 7, since the optimal foaming pH of the amino acid surfactant is within this range; but in this range, the optimum foam peak of the glycine surfactant is in the surface of the glutamate surface. The active agent is slightly different. Washing milk is mainly a dairy product consisting of an oil phase raw material, aqueous phase, partially free surfactant, nutrient, moisturizer, and a phase. The composite is the principle of its cleaning, the oil on the skin, and then dissolve the stains and dirt on the skin with water. In addition, some free surfactants in the washing milk have five major functions of wetting, dispersion, foaming, decontamination and emulsification. Washing milk is mainly divided into two categories: soap and active agents. Soap facial cleanser and cleansing soap differences. After use, the refreshing is not burden, but it will be tight. Long-term use will promote skin aging, but there is a lot of space in the market. The main ingredients include nonionic surfactants, cationic surfactants, silicon surfactants, antistatic agents, deionized water, defoamer, essence, effectively removes heavy oil around the hood and gas stove.
