Isopropyl Myristate
Widely used in cosmetics, it can moisturize and moisturize the skin. The skin has a good absorption of this product. It can effectively contact with hair follicles in the cortex, penetrate into the deep cortex, and bring the active components of cosmetics into full play. As cosmetic solvent and skin moisturizer, penetrant.
Isopropyl Palmitate
Widely used in pharmaceutical and cosmetics industry. It is mainly used as additive and solubilizer. Isopropyl palmitate has stable performance and is not suitable for oxidation to produce peculiar smell. It is an excellent skin softener in skin care and cosmetics, which can make skin soft, tender and smooth without greasy feeling. It has good skin permeability and can be used as a good solvent for mascara. It is commonly used in skin cream, hair oil, eye shadow, lipstick, mascara and other formulations.
L(+)-Ascorbic Acid
Vitamin C is soluble in water, slightly soluble in ethanol, insoluble in ether, chloroform, benzene, petroleum ether, oil and fat. The aqueous solution shows acid reaction. It can be oxidized to dehydroascorbic acid quickly in the air, with citric acid like acid taste. It is a strong reducing agent and gradually turns to light yellow in different degrees after long storage. This product exists in all kinds of fresh vegetables and fruits. This product plays an important role in biological oxidation and reduction and cell respiration, which is conducive to the synthesis of nucleic acid and the formation of red blood cells. It can also reduce Fe3 + to Fe2 +, which is easy to be absorbed by human body, and is also beneficial to cell generation.
L-Serine
Hexagonal lamellar crystal or prismatic crystal. Dissolve in water (20 ℃, 25g / 100ml water). It is used in biochemical research, preparation of tissue culture medium and medicine as amino acid nutrition medicine.
LANOLIN
Lanolin can make skin smooth and tender. It was first found that its skin beautifying effect was due to the fact that the hands of Australian sheep workers were generally tender than those of ordinary people. Later, it was found that lanolin played a role. In industry, it is used to prepare advanced antirust oil, low temperature lubricant, printing ink, fiber oil agent, leather fatliquoring agent, plastic plasticizer, latex defoamer, etc. In medicine, it is used to prepare rheumatism ointment, zinc oxide plaster and ointment base material. Cosmetic grade lanolin can be used for cold cream, anti wrinkle cream, anti crack cream, shampoo cream, hair conditioner, hair cream, lipstick and high grade soap. It is often used as water in oil emulsifier and is a good moisturizing substance. It can soften and recover dry or rough skin due to lack of natural moisture. It maintains the usual moisture content of the skin by delaying, rather than completely preventing, the passage of water through the epidermis.
Lactic Acid
Lactic acid is a colorless or yellowish liquid, which can be purified by steam distillation. It can be fractionated repeatedly under the vacuum condition of 67-133pa to obtain high purity lactic acid, and then obtain monoclinic crystal crystalline lactic acid. Lactic acid and oxidant, iodide, nitric acid, egg white can not coexist, otherwise it is harmful to human body. It is naturally found in the germination of milk, jam of fruit, juice of tomato, beer, wine and many higher plants.
Methylparaben
Methyl p-hydroxybenzoate, also known as Methyl Paraben or methylparaben, white crystal powder or colorless crystal, soluble in alcohol, ether and acetone, very slightly soluble in water, boiling point 270-280 ℃. It is mainly used as antiseptic for organic synthesis, food, cosmetics and medicine, and also as feed antiseptic. Because of its phenolic hydroxyl structure, it has better antibacterial properties than benzoic acid and sorbic acid. The mechanism of action is to destroy the cell membrane of microorganism, denature the protein in cell, and inhibit the activity of respiratory enzyme system and electron transfer enzyme system of microorganism cell.
Mineral Oil
This product is a mixture of refined liquid hydrocarbon obtained from petroleum, which is mainly a mixture of saturated cycloalkanes and alkanes. Crude oil is often fractionated under pressure and pressure, solvent extracted and dewaxed, and hydrotreated. Including light and heavy fuel oil, lubricating oil, cooling oil and other mineral hydrocarbons. Mineral oil can float on the surface of water body and affect the exchange of oxygen between air and water body interface; it can also disperse in water, adsorb on suspended particles or exist in water in emulsion state and be oxidized and decomposed by microorganisms in water, which consumes dissolved oxygen in water and worsens water quality.
Nicotinamide
Nicotinamide, also known as nicotinamide, is an amide compound of nicotinic acid. White crystalline powder; odorless or almost odorless, bitter taste; slightly hygroscopic. Soluble in water or ethanol, soluble in glycerin. Clinically, it is mainly used to prevent and treat pellagra, stomatitis, glossitis, sick sinus syndrome, atrioventricular block and other problems.
Orange Sweet Oil
Sweet orange is a small evergreen tree belonging to citrus of Rutaceae. Mainly produced in Brazil, the United States, Israel, Italy, Spain, Morocco, Guinea, Australia, Indonesia, Russia and China's south and East China. Cold pressed sweet orange oil can be obtained by cold grinding fresh whole fruit (oil yield is 0.35% ~ 0.37%) or cold pressing fresh peel (oil yield is 0.3% ~ 0.5%); or by steam distillation with residue or collected crushed peel after cold pressing, sweet orange oil can be distilled with oil yield of 0.4% ~ 0.7%.
Sodium Hyaluronate
Sodium hyaluronate, also known as sodium hyaluronate, is a widely existing physiological active substance in human body. It is a high molecular weight straight chain mucopolysaccharide, which is polymerized by the disaccharide unit composed of glucuronic acid and acetaminohexose. Its molecular weight is 1 million. It can form a thick viscoelastic solution in water with physiological pH and ionic strength. Its molecular form is variable, so it can also be passed by a finer injection needle. The substance in sodium hyaluronate that does not produce inflammation is extracted, which is called Helon. When 10mg of this product is dissolved in 1ml of normal saline, its viscosity can be 200000 times higher than that of room water or normal saline. The protein content of Healon is less than 0.5%, which is a sterile high purity solution.
Turpentine Oil
Turpentine is an oil-bearing resin of coniferous trees. The natural oil-bearing resin (resin turpentine) is a yellowish opaque block, and its distillate is turpentine, the latter is a colorless volatile liquid. It has a special smell. Turpentine is widely used as a chemical raw material. It has opportunities to contact turpentine in art glass, paint, camphor manufacturing, pharmaceutical, rosin manufacturing and other industries.
