Tranexamic Acid with CAS 1197-18-8 is a synthetic derivative of lysine. It is a commonly used hemostatic agent in clinical practice. It plays a hemostatic effect by inhibiting the dissolution of fibrin. Trantranic acid can strongly adsorb Lysine-binding sites of fibrinogen affinity sites on plasminase and plasminogen, and inhibit the binding of plasminogen and fibrin, and thus strongly inhibit the decomposition of fibrin caused by plasminogen. In addition, the antifibrinolytic effect of tranatemic acid was more obvious in the presence of antifibrinolytic enzymes such as macroglobulin in serum

Indene, also known as benzocyclopropene, is a polycyclic aromatic hydrocarbon with low toxicity and irritation to human skin and mucous membranes. It exists naturally in coal tar and crude oil. In addition, indene is also released when mineral fuels are not completely burned. Molecular formula C9H8. Molecular weight 116.16. The benzene ring and cyclopentadiene in its molecule share two adjacent carbon atoms. It appears as a colorless liquid, does not volatilize in vapor, turns yellow when standing still, but loses color when exposed to sunlight. Melting point -1.8°C, boiling point 182.6°C, flash point 58°C, relative density 0.9960 (25/4°C); insoluble in water, miscible with ethanol or ether. Indene molecules contain highly chemically active olefin bonds, which are prone to polymerization or addition reactions. Indene can polymerize at room temperature, and heating or in the presence of an acidic catalyst can increase the polymerization rate sharply, and react with concentrated sulfuric acid to form secondary indene resin. Indene is catalytically hydrogenated (see catalytic hydrogenation reaction) to form dihydroindene. The methylene group in the indene molecule is similar to the methylene group in the cyclopentadiene molecule. It is easily oxidized and reacts with sulfur to produce a complex, which has a weak acid reaction and reducing properties. Indene reacts with metallic sodium to form sodium salt, and condenses with aldehydes and ketones (see condensation reaction) to form benzofulvene: Indene is separated from the light oil fraction obtained from the distillation of coal tar in industry.

Since these materials are prepared in aqueous solutions, there is no particular advantage in using the anhydrous hydroxide for the preparation. Other salts of weak and strong acids may be prepared using lithium hydroxide as a starting material. The preparation of anhydrous lithium hydroxide has already been described.

Glyceryl monoLaurate (abbreviated as GML), corresponding to CAS 142-18-7, is a monoester compound formed by the esterification reaction of lauric acid (dodecanic acid) and glycerol (mainly composed of glyceryl monolaurate, often containing small amounts of diester and triester impurities). Glyceryl monoLaurate is a naturally occurring nonionic surfactant. Monolaurin is also a substance with multiple functions such as emulsification, antibacterial and nutritional, and is widely used in various fields.
Glycerol laurate is a white to pale yellow powder, thin sheet or waxy solid at room temperature, odorless or slightly oily. The melting point is approximately 63-66℃. Monolaurin is insoluble in water but readily soluble in organic solvents such as ethanol, glycerol, and vegetable oil. When heated (e.g., above 70℃), it can disperse in water to form an emulsion.
Monolaurin 142-18-7 possesses the typical characteristics of esters and can undergo hydrolysis reactions under acidic and alkaline conditions, generating lauric acid and glycerol. Glyceryl monoLaurate has good stability and is not prone to decomposition under conventional food and cosmetic processing conditions (such as heating and sterilization), and is highly compatible with most ingredients.

Natural food preservatives (antibacterial agents) : This is the prominent application of GML. Monolaurin has a significant inhibitory effect on various Gram-positive bacteria (such as Staphylococcus aureus, Listeria, Bacillus subtilis, etc.) and fungi (such as yeast, mold), especially showing excellent results against microorganisms that cause food spoilage. Monolaurin also has a certain inhibitory effect on Gram-negative bacteria (such as Escherichia coli and Salmonella) (and can be combined with other preservatives to enhance the effect). It is widely used in dairy products (yogurt, cheese, milk beverages), meat products (sausages, hams), pastries, beverages, condiments, etc., to extend the shelf life of food and without the potential risk of chemical preservatives.
Food emulsifier: Monolaurin, as a nonionic emulsifier, can improve the compatibility of oil and water systems in food, evenly disperse oils in the aqueous phase, prevent stratification and sedimentation, and enhance the texture and stability of food. For example, when used in baked goods such as cakes and bread, it can improve the extensibility of the dough and make the finished product soft in texture. Monolaurin can be used in ice cream and chocolate to enhance fineness and melting stability.
Nutritional fortifier: Lauric acid is an important source of medium-chain fatty acids in the human body, featuring rapid energy supply and low fat accumulation. GML can be used as a carrier of medium-chain fatty acids in infant formula foods, sports nutrition foods, etc., to supplement nutrition.
2. Cosmetics and daily chemical industry
Emulsifiers and foam stabilizers: Monolaurin is used in products such as face creams, lotions, shampoos, and body washes as an oil-in-water (O/W) type emulsifier, helping oils and water form stable emulsions and preventing product stratification. Meanwhile, glyceryl monolaurate
It has a foam-stabilizing effect and can improve the density and durability of the foam in daily chemical products.
Mild antibacterial agent: By taking advantage of its antibacterial properties, it is used in skin care products, oral care products (such as toothpaste, mouthwash), private part care products, etc., to inhibit harmful microorganisms on the skin and oral surface, reduce the odor and inflammation caused by bacterial growth, and at the same time does not irritate the skin and mucous membranes (suitable for sensitive skin products).
Skin conditioner: Monolaurin 142-18-7 can form a gentle protective film on the skin surface, lock in moisture, improve dry skin conditions, and at the same time enhance the skin feel of the product, making it smoother and less sticky after application.
3. In the field of medicine and health products
Pharmaceutical excipients (emulsifiers, antibacterial excipients) : Monolaurin 142-18-7 is used in topical preparations such as ointments, creams, and suppositories. As an emulsifier, it ensures the uniform dispersion of drug components and enhances the stability of the preparations. At the same time, its antibacterial effect can assist in inhibiting bacterial infection on skin wounds and promoting wound healing.
As a medium-chain fatty acid ester, Glycerol laurate can be used in weight loss health products, intestinal health products, etc. Its metabolic product, lauric acid, helps regulate the balance of intestinal flora and provides energy quickly, making it suitable for people who need to control their weight or increase their energy.
4. Other fields
Feed additive: Glycerol laurate is used in livestock, poultry and aquatic feed as a natural antibacterial agent to inhibit harmful microorganisms (such as mold and pathogenic bacteria) in feed, prevent feed spoilage, and at the same time improve the intestinal health of animals, increase feed conversion rate and promote animal growth (such as in the feed of piglets and chicks).
Additive for daily chemical industry: Monolaurin 142-18-7 is used in detergents and cleaning agents, which can enhance the decontamination ability and emulsification effect of the products, while reducing the irritation to the skin. Monolaurin is suitable for mild cleaning products.
