  Velcorin , also known as dimethyl dicarbonate, is a preservative approved by the Ministry of Health and complies with the Food Sanitation Law of the People's Republic of China and the Food Additive Sanitation Management Measures. The molecular formula is C4H6O5, and the relative molecular mass is 134.09. The boiling point is 172 ° C, at room temperature, it is a slightly astringent colorless liquid, usually used in beverage cans. DMDC has a broad-spectrum antibacterial effect. Its main target microorganisms are yeasts (including Saccharomyces cerevisiae, Zygosaccharomyces ruckerii, Rhodotorula, Candida, Pichia, Toluobacillus, Torula, Endosporium, Klerkia, Hansenula, etc.). It also has a disinfecting effect on many other bacteria (such as Acetobacter pasteurianus, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, various lactobacilli, Pediococcus beer). DMDC has also been shown to kill E. coli 0157:H7. The antibacterial effect of DMDC is the result of inactivating e

    Redispersible latex powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers,  vinyl acetate/tertiary ethylene carbonate copolymers , acrylic copolymers, etc. agent, with polyvinyl alcohol as protective colloid. This powder can be quickly redispersed into an emulsion after contacting with water. Due to the high binding ability and unique properties of redispersible polymer powders, such as: water resistance, construction and heat insulation, etc., their The range of applications is extremely broad. It has outstanding bonding strength, improves the flexibility of the mortar and has a longer opening time, endows the mortar with excellent alkali resistance, and improves the adhesiveness, flexural strength, water resistance, plasticity and wear resistance of the mortar. In addition to the construction property, it has stronger flexibility in the flexible anti-crack mortar. Dry-mix formulations are essential for transporting and k

  Both natural sweeteners found in fruits and plants which are used as a lower calorie, natural sugar alternative, and are often used by those trying to maintain their blood sugar levels.  They are sugar alcohols. To get technical: “alcohol” is simply referring to a chemical structure. Sugar alcohols are modified forms of sugar and not technically an actual sugar, which is why foods containing erythritol and xylitol can be labeled “sugar-free.” Unlike sugar, honey, and maple syrup, they not trigger a spike in the blood glucose as well as a response in insulin, which can cause diabetes and weight gain. It has been researched that  Erythritol  is better in terms of: Better aftertaste, preferred sugar substitute for people with diabetes, promotes oral health and doesn’t lead to tooth decay, and xylitol also aids in the prevention of cavities and reduces plaque formation. Causes less digestive distress. (unlike Xylitol has gastrointestinal side effects from xylitol, such as gas, bloating a

Customers typically ask what is the distinction in the application of DTF ink and also  DTG pigment ink . For this trouble, let me evaluate it thoroughly. Prior to the analysis, permit's mention the current market's names for DTG pigment inks. Numerous of them describe DTF Textile Ink, as well as some are called movie transfer inks. Actually, DTF textile  printing inks , in addition to film transfer, inks 2 names of ink are fairly comprehensive. DTF textile printing ink will absolutely be a bit additional basic, generally stressing the application of DTF pigment ink.   What is Direct to Garment (DTG) printing? Direct-to-Garment Printing or DTG is a popularly known, is a printing process that is very similar to printing on paper, just that the medium used here is fabric. In fact, it was the paper printing inkjet machines that inspired DTG printing. The roots of Direct to Garment technology are in injection printers, which were first invented in the 1950s and became a common feat

  Potassium sorbate was discovered by the French in the 1850s from the berries of the mountain ash tree. It extends the shelf life of foods by preventing the growth of molds, yeasts, and fungi. Its safety and use as a preservative have been studied for the past fifty years. It was recognized as safe by the U.S. Food and Drug Administration (FDA) when used appropriately. You will find   potassium sorbate   on the ingredient lists of many common foods. So what exactly does potassium sorbate do? Next, the  potassium sorbate supplier   will share the following content with you. What Is Potassium Sorbate? How Potassium Sorbate Is Made What Does Potassium Sorbate Do in Our Products? Is Potassium Sorbate Safe To Eat? Why We Use Potassium Sorbate？ What is potassium sorbate? Potassium sorbate is a salt of sorbic acid, naturally found in some fruits (such as sorrel berries). Commercial ingredients are produced synthetically, creating so-called "identical" chemicals (chemically equivale

  Diethyl oxalate  (C6H10O4) is also known as diethyl oxalate, ethanedioic acid and diethyl ethanedioate. It is a white solid compound synthesised from carbon monoxide and ethanol. It is slightly denser than water and insoluble in water. Diethyl oxalate is available in powder and liquid forms. It is a colourless toxic compound with a characteristic odour. It has important applications in various end-user industries such as pharmaceuticals, agriculture and cosmetics. The compound is mainly used as a raw material or intermediate in the manufacture of phenobarbital and a variety of dyes; it is also used as a solvent in natural and synthetic resins as well as in nitrocellulose lacquers and various chemical synthesis processes. Further, it is used as a chemical intermediate in the synthesis of active pharmaceutical ingredients. Diethyl oxalate is also used as a cost-effective additive in dye-sensitised solar cells. Diethyl oxalate  is used in the production of agrochemicals such as pesticid

  Xylitol  reduces the levels of MS in the mouth. It essentially starves the MS bacterium by not providing any energy to it when metabolized. Since xylitol is a non-nutritive sugar the MS bacteria spend energy to metabolize it and in return receive no energy gain from it. It's a sunken cost and the S. mutans cannot keep growing. This reduces the population of S. mutans and impedes the ability of plaque and bacteria to adhere to our teeth. It also decreases the amount of lactic acid present in our mouth, making our teeth less vulnerable to decay. Curiously xylitol does all of this without affecting the other benefits, or overall, flora of our mouths.   Another amazing find has been that when a mother of a newborn uses xylitol, that child's teeth prove to be more resilient against cavities as they develop. Children have a dramatically lower risk of cavities when their mothers use xylitol starting 3-6 months after childbirth and continue using it until all their baby teeth are for

  Hydroxypropyl methylcellulose is one of the key ingredients in dry-mix mortars because of its ability to influence key dry-mix properties such as water retention, curing, workability, rheology, and thixotropy. 1. Water Retention The excellent water retention of hydroxypropyl methylcellulose gives the cement a longer hydration time and improves the adhesion of the mortar to the substrate. It effectively prevents the mortar from losing water too quickly and causing dryness and cracking, allowing the mortar to be worked for longer. The viscosity, dosage, ambient temperature, and molecular structure of HPMC have a significant impact on its water retention properties. Under the same conditions, the higher the  viscosity of HPMC , the better the water retention; the higher the content, the better the water retention.  Generally, a small amount of HPMC can greatly improve the water retention rate of mortar. When the content reaches a certain level, the trend of increasing water retention sl

In   the  pharmaceutical industry , you may hear the terms "FDF" and "API" that are often used to refer to products. Of course, within the industry itself, we understand this type of jargon, but of course we can see that the general public is at a loss when they see these acronyms. For reference, they represent "finished dosage form" and "active drug ingredient" respectively. It is true that the world of solid dose production can be quite technical and complex, but if our work is so opaque and confusing, it makes no sense. In this case, we will use this article to discuss  the differences between FDF and API  and how the two drug preparation processes relate to each other.     What is FDF? FDF stands for finished product dosage form, which refers to the actual finished product used for consumption. FDF can take many forms, including solid tablets or capsules, liquid solutions or other types. FDF usually contains API and various inactive component
