Aqueous Enteric Coating

UV Varnishes A UV coating is a surface treatment which either is cured by ultraviolet radiation, or which protects the underlying material from such radiations harmful effects. Screen UV Matte Varnish. Screen UV Texture Varnish. Screen UV Laminate Varnish. UV Varnish Print. Having excellent gloss is suitable for fast curing for full/flat over print coating of all types of printed paper and boards & used on Anilox Roller Chamber Coating System or Roller Coater System. The products can be used for coating of mono-cartons, book titles, other packaging material and various types of labels used in labelling industry. Advantages: 1. Pollution-free, non-hazardous, eco-friendly, Free of volatiles. 2. All grades have good levelling & slip. 3. Excellent scuff resistance with good gloss and free of any residual tack. 4. Colorless coating, no yellowish tinge on coated paper.

Product Name: Citric Acid Monohydrate Molecular Formula: C6H10O8 Molecular Weight: 210.14 Appearance: White Crystalline Powder Purity: 99% CAS Number: 5949-29-1 EINECS number: 200-662-2 Mesh: 12-100 Standard: BP/USP/FCC/E330/GB1886.235-2016 Supplier: ZHENYIBIO Usageï¼?Citric Acid Monohydrate is used as an Acidulate, Food additive, Pharmaceutical application and as a synergist in antioxidant mixtures. Citric Acid Monohydrate is a tricarboxylic acid found in citrus fruits. Citric acid is used as an excipient in pharmaceutical preparations due to its antioxidant properties. It maintains stability of active ingredients and is used as a preservative. It is also used as an acidulant to control pH and acts as an anticoagulant by chelating calcium in blood. Applications: Citric acid (as either the monohydrate or anhydrous material) is widely used in pharmaceutical formulations and food products, primarily to adjust the pH of solutions. It has also been used experimentally to adjust the pH of tablet matrices in enteric-coated formulations for colon-specific drug delivery. Citric acid monohydrate is used in the preparation of effervescent granules, while anhydrous citric acid is widely used in the preparation of effervescent tablets. Citric acid has also been shown to improve the stability of spray-dried insulin powder in inhalation formulations.

Performance characteristics 1. As a broad-spectrum, long-lasting bactericide to kill many bacteria, fungi and yeasts, the using amount is small. 2. Suitable for use in the medium of the pH value in the range of 2 to 9; free of divalent salt, cross-link no emulsion. 3. Miscible with water; can be added in any production step; easy to use. 4. It has a low toxicity and an appropriate concentration of using, which will lead to no harm completely. Usage and Cautions 1. In water treatment applications, dilute it into a 1.5% aqueous solution first. Add the solution at a quantity of 80 to 100 ppm for one or two times each week depending on the multiplication of microorganisms like bacteria and algae. 2. Avoid direct eyes' contact with it for a long period. Once the contact happens, rinse eyes with water without delay. No long-term contact with the skin is allowed. 3. Any contact with reducible metals is forbidden during storage, for example, iron and aluminum, so as to avoid decomposition. 4. Not suitable for use in the alkaline medium of pH> 9.0 due to its poor stability. Any combination of this chemical with highly nucleophilic chemicals, like S2- and R-NH2, will lead to declined quality or even complete failure of the product.
