Haimeng study Industrial Co., the manufacturer of high-quality, detailed description of lactic phone manufacturers, lactic acid CAS number, lactic acid, lactic latest offer Shanghai, lactic acid prices, the role of lactic acid, lactic acid factory distributor, lactic acid manufacturers latest offer, lactic the amount of the formula: C3H6O3. Simple structure: CH3CH (OH) COOH. CAS: 20-21-5. English: Lactic acid Properties: colorless liquid, odorless, hygroscopic. The relative density of 1.2060 (25/4 ℃). 18 ℃ melting point. Boiling point 122 ℃ (2kPa). Refractive index nD (20 ℃) ??1.4392. With water, ethanol, glycerin, insoluble in chloroform, carbon disulfide and petroleum ether. Thermal decomposition under normal pressure, concentrated to 50%, into milk portion anhydride, thus products often contain 10% to 15% milk anhydride. Because having a hydroxyl group and a carboxyl group, under certain conditions, the esterification reaction can occur, there are three types of product. The use of lactic acid in the food industry 1) Preservation of lactic acid has a strong effect, can be used in wine, beverage, meat, food, pastry, vegetables (olives, cucumbers, pearl onions) pickled and canned food processing, food processing, fruit storage, regulate the pH, antibacterial, extend shelf life, flavor, keep food color, improve product quality and so on; 2) seasoning aspect, lactic acid distinctive sour taste of the food increase, in salads, soy sauce, vinegar spices adding a certain amount of lactic acid, the product can be maintained in the microbial stability, security, and make the taste milder; 3) Because lactic acidity mild moderate, but also as a careful deployment of soft drinks and juices preferred acidulant ; 4) When the brewing of beer, add the amount of lactic acid to adjust the pH value both to promote saccharification, is conducive to yeast fermentation, improve the quality of beer, but also increase the beer flavor, extend shelf life. In wine, sake and wine used to adjust the pH, to prevent bacteria growth, enhancing sour and refreshing taste; 5. buffered lactic acid can be used in hard candy, fruit candy and other confectionery products, moderate acidity and sugar conversion rate. Lactic acid powder can be used on all kinds of candy powder, sour agent as a powder; 5) natural lactic acid is an inherent part of the natural dairy products, it has a taste and a good anti-microbial effect of dairy products, has been widely used for deployment type yogurt, cheese, ice cream and other foods, dairy products become acclaimed sour agent; 6) lactic acid powder is a direct acidity regulator for the production of buckwheat head. Lactic acid is a natural acid fermentation, so you can make bread with a unique taste; acid as a natural acidity regulator, bread, cakes, biscuits and other baked goods for flavor and antibacterial effect, and can improve the quality of food, to maintain color , extend shelf life. Use of lactic acid in medicine 1) in the ward, operating rooms, laboratories and other places in lactic acid steam sterilization, can effectively kill airborne bacteria, decrease the risk of disease, to improve health purposes; 2) widespread in medicine as a preservative, a carrier, cosolvent, pharmaceutical preparation, pH adjusting agent; 3) polymerization of polylactic acid, polylactic acid can be pumped into a silk spinning into a line, this line is good surgical sutures, healing slot After no stitches, it can automatically degraded into lactic acid is absorbed by the body, without adverse consequences. Especially in vivo surgical suture, eliminating the second surgery stitches trouble. This polymer compound can be made into an adhesive used in organ transplantation and bone; and 4) Lactic acid can be formulated into pharmaceutical or made use of lactate; 5) of muscle activity and fatigue of the restraining effect. Lactic acid used in the industry 1) lactic acid for pH control and improve the purity of the fermentation in the fermentation industry; 2) in cigarette tobacco industry to maintain the humidity, to remove impurities in tobacco, changing tastes, higher tobacco grades, lactic acid may also nicotine and nicotine, reduce harmful ingredients to improve the quality of tobacco; 3) in the textile industry for handling fiber, fiber can be easily pigmented shine to make soft touch; 4) is used as a pH adjuster in the coating ink industry agents and synthetic agents; in biodegradable plastic fiber new materials industry is the preferred raw material polylactic acid PLA; and 5) polylactic acid may be used as a starting material, produce a new generation of biodegradable plastics; 6) in the leather industry , lactic acid may be stripped of leather lime and calcium, make the leather soft and fine, which is made of quality leather; 7) lactic acid due to the nickel complex has a unique constant, often used in nickel plating, it also can be used as electroplating slot pH buffers and stabilizers. In the microelectronics industry, its unique high purity and low metal content to meet the quality requirements of the semiconductor industry, which as a safe organic dissolving agents may be used for cleaning the photosensitive material; 8) lactic acid as a pH adjusting agent and synthetic agent can be applied to a variety of water-based coating of adhesive systems. Such as: electrodeposition coating material. Low boiling acid product is ideal for security systems developed for high dissolved solids coatings. Lactic acid product line for the production of coatings with good flow properties with high solids provided an opportunity; 9) the role of lactic acid having a cleaning detergent, cleaning products for washing a better performance than traditional organic detergents, so it can be applied in many cleaning products. Such as: toilet, shower, coffee maker cleaner. Lactic acid has anti-microbial resistance, when it and other anti-microbial agents such as ethanol with the use of a synergistic effect. Lactic acid used in the cosmetic industry 1) Because L- lactic acid is part of the natural skin natural moisturizing factor is widely used in many skin care moisturizer. L- lactic acid is the most effective AHA and irritating little; 2) Since the L- lactic acid is naturally present in the hair, the effect is to make the hair shiny surface, so lactic acid is often used as hair care products, pH adjusting agent; 3) lactic acid can be used as a moisturizer for a variety of bath wash articles such as bath gel, bar soap and soothing honey. Liquid soap, soap and shampoo can be used as a pH adjusting agent. In addition, lactic acid added in a strip soap can reduce the loss of moisture during storage, thus preventing soap dry. Lactic acid in the agricultural products and agricultural uses 1) up to 99% optical purity of lactic acid, the pesticides used to produce sustained release of pesticides, such as herbicides, with a non-toxic and harmless to crops and soil characteristics and efficient; 2) lactic acid polymers used in the production of agricultural film, use it to replace the plastic mulch, after bacterial decomposition can allow the soil to absorb, environmentally friendly; 3) Lactic acid is also used for green fodder storage agent, pasture ripening agent; 4) as a growth promoter in swine and poultry feed agent. Lactic acid can reduce the PH value of the stomach, plays activate digestive enzymes, improve the role of amino acid digestion, and the growth of beneficial intestinal epithelium. A few weeks after weaning piglets were fed feed containing an acidifying agent, its weight during weaning can be increased by 15%; 5) lactic acid to inhibit the growth of microorganisms. Lactating piglets will be infected by the diseases caused by E. coli and salmonella in feed added lactic acid can prevent the growth of pathogenic bacteria in the gastrointestinal tract piglets; 6) Lactic acid can be used as feed preservative and to enhance feed, grain and meat processing product by-product of microbial stabilizer; 7) by adding lactic acid in poultry and pig drinking water, can effectively inhibit the growth of pathogens, animal weight gain speed. Toxicity protection pure non-toxic. As long as its salts are non-toxic heavy metal salts. Oral LD50 for rats 3730mg / kg. Quality indicators: (GB 2023-80) content ≥80% Chloride ≤0.002% ≤0.001% iron sulfate ≤0.01% Residue on ignition ≤0.1% Heavy Metals ≤0.001% Arsenic ≤0.0001% Haimeng study Industrial Co., integrity management, Welcome to the new and old customers call to discuss!
