Essence is an indispensable and important raw material in cosmetics. In personal care products, the essence mainly plays the role of making the product fragrant and has aesthetic value. In addition to perfuming, fragrances have other useful functions. Because human odor senses accept the smell of flavor, and the sense is closely related to the emotional part of the brain, flavor has a great impact on human emotions.
Potassium laurate can be used as emulsifier and foaming agent in industry. Main ingredient in body wash and hand sanitizer. For liquid laundry soap, it has good detergency and makes clothes easier to rinse. Emulsifier in disinfectant.
Name: Triethanolamine
CAS: 102-71-6
Chemical formula: C6H15NO3
Appearance: colorless liquid
Triethanolamine is a colorless oily liquid with mild odor, easy to absorb water, exposed to air and turning brown under light. At low temperatures, it becomes a colorless or light yellow cubic crystal system.
Application:
1. As a compliant lubricant, it can eliminate friction between metals and help improve the viscosity and solubility of lubricating oil.
2. As a surfactant, it is often used in household cleaning and personal care products such as detergents, cleaners, softeners, etc.
3. As a preservative, stabilizer, and co solvent, it can be used in cosmetics, and food processing.
4. As an oil in water emulsifier, it can be used to prepare various skin lotion and cosmetics.
Manganese hydroxide is a white substance with hexagonal crystal form. Chemical formula: Mn(OH)2. The relative density is 3.258. It decomposes easily when heated, is insoluble in water and alkali, and readily soluble in ammonium salts of acids and strong acids. It is quickly oxidized into brown compounds when exposed to air.
Purpose
Manganese hydroxide can be used as a ceramic pigment. It is also used in the production of other manganese compounds and for the treatment of wastewater containing organic acids in zinc electrolysis workshops.
Sodium polyacrylate is a white powder. Odorless and tasteless. Very hygroscopic. Polymer compounds with hydrophilic and hydrophobic groups. Slowly dissolves in water to form a very viscous transparent liquid. The viscosity of its 0.5% solution is about Paâ?¢s. The viscosity is not caused by water absorption and swelling (such as CMC, sodium alginate), but due to the many anionic groups in the molecule. The ionic phenomenon causes the molecular chain to grow and the viscosity increases to form a highly viscous solution. Its viscosity is about 15-20 times that of CMC and sodium alginate. Heat treatment, neutral salts, and organic acids have little effect on its viscosity, but when it is alkaline, the viscosity increases. Insoluble in organic solvents such as ethanol. Strong heat to 300 degrees does not decompose. The long-term viscosity changes very little, and it is not easy to decay. Because it is an electrolyte, it is susceptible to the influence of acid and metal ions, and the viscosity is reduced.
Sodium acetate anhydrous occurs as colorless, transparent crystals or as a granular, crystalline or white powder. The anhydrous form is hydrous from dissolves in about 2ml water, 1g of the trihydrate dissolves in about 0.8ml water and in about 19ml alcohol.
Sodium acetate anhydrous can be used as suffering agent flavoring agent and PH conditioning agent in food industry. It also can be used as accessory in pharmaceutical industry.
Lithium chloride (chemical formula: LiCl) is an alkali metal halide, a white, deliquable solid at room temperature. Due to the smaller ionic radius and higher hydration energy of lithium, the solubility of lithium chloride is much greater than that of other chlorides (83g/100mL, 20�°C). Its aqueous solution is alkaline. Lithium chloride is a sodium chloride type structure, in which the chemical bond is not a typical ionic bond, so it can be dissolved in many organic solvents, and ethanol, amines can form different admixtures. This property can be used to separate lithium chloride from alkali metal chlorides.
Ammonium chloride is colorless crystal or white crystalline powder; Odorless, salty, cool; It is moisture, soluble in water, slightly soluble in ethanol. Mainly used in batteries, electroplating, dyeing and weaving, casting, medicine, flocking, fluff, for dry batteries, fabric printing and dyeing, fertilizer, tanning, detergent, chemical intermediates and so on.
PHYSICAL PROPERTIES
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium. It has an empirical formula of MgO. Pure MgO is not conductive and has a high resistance to electric current at room temperature.
APPLICATION
1.Heating elements. MgO is as a refractory material. MgO is used as a basic refractory material for crucibles.
2.Fireproofing. As a construction material, magnesium oxide wallboards have several attractive characteristics: fire resistance, termite resistance, moisture resistance, mold and mildew resistance, and strength.
3.Gas mantles. Most gas mantles utilize magnesium oxide.
4.Magnesium oxide is used extensively in the soil and groundwater remediation, wastewater treatment, drinking water treatment, air emissions treatment, and waste treatment industries for its acid buffering capacity and related effectiveness in stabilizing dissolved heavy metal species.
5.Medical.Magnesium oxide is used for relief of heartburn and indigestion, as an antacid, magnesium supplement, and as a short-term laxative. It is also used to improve symptoms of indigestion. Side effects of magnesium oxide may include nausea and cramping.
6.As a food additive, it is used as an anticaking agent.
Liquefied by hygroscopic agglomeration. Becomes brown when melting, later turns to green gradually, still turns white after cooling.1g dissolves in 0.5ml ace*tone, 12ml ethanol, 8ml boiling ethanol. Soluble in water. When dissolved in its own weight of water, the temperature drops about 30 �ºC. Aqueous solution is neutral. Low toxicity, LD50 (rat, oral) 854mg/kg.
Prepare thiocyanate titrants. Determine trivalent iron, copper and silver. Urine test. Tungsten color developer. Indicator for volumetric determination of titanium. Cooling agent. Photographic thickening agent.
