What Is Zinc Dihydrogen Phosphate Used For in Metal Pretreatment?
Zinc dihydrogen phosphate (CAS 13598-37-3) supplies zinc and phosphate to acidic baths used to pretreat metal before painting, powder coating or electrocoating. The bath forms a crystalline phosphate layer on the metal. This layer provides a base for the finish, and its performance depends on th...Read more -
How to Choose Pectin for Jams and Fruit Fillings
In traditional jams and jellies, high-methoxyl (HM) pectin forms a gel when soluble solids are high enough and the pH is sufficiently low. Low-methoxyl (LM) pectin can gel through calcium at lower soluble solids. For fruit fillings, the choice also depends on when the gel needs to set and how it...Read more -
Fe-HEDTA for Plants and Iron Chelate Selection
Fe-HEDTA, also called ferric HEDTA (CAS 17084-02-5), is a chelated form of iron used in plant nutrition. Chelation helps keep iron in solution. The choice of chelate depends on the pH and conditions around the roots, whether the crop grows in soil, a container substrate or a nutrient solution. W...Read more -
C9–11 Alcohol Ethoxylates in Cleaning and Textile Wetting
C9–11 alcohol ethoxylates (CAS 68439-46-3) are nonionic surfactants used in detergents, hard-surface cleaners and textile processing. They help water wet surfaces and lift oily soils. The average degree of ethoxylation affects how the surfactant behaves in water, so grades with the same CAS numb...Read more -
Ethyl Cellulose Uses in Coatings, Inks and Tablets
Ethyl cellulose (EC, CAS 9004-57-3) is a cellulose ether that forms water-insoluble films. In solvent-based inks and coatings, it can bind solids and form a film as the solvent evaporates. In oral dosage forms, suitable grades form a barrier around tablets or pellets or help control release from...Read more -
PVP K30 Uses in Tablets and Hair Styling
PVP K30, also called povidone K30, is a water-soluble grade of polyvinylpyrrolidone (CAS 9003-39-8). In tablet manufacturing, it helps bind powder particles into granules. In hair styling, it forms a film as the product dries. The grade, solvent system and finished-product requirements determine...Read more -
PMDA for Polyimide Film Manufacturing
Pyromellitic dianhydride (PMDA, CAS 89-32-7) is an aromatic monomer used to make polyimide films. For film producers, the incoming grade matters because monomer purity and the balance of reactive groups affect the precursor used for coating or casting. Free acid and moisture exposure are two sep...Read more -
Anthraquinone in Dye Intermediate Manufacturing
Anthraquinone (CAS 84-65-1) is a starting material for manufacturing anthraquinone-based colorants and their intermediates. The selected synthesis route determines which raw material characteristics matter most. Assay, moisture and ash are useful grade checks, and specific impurity limits can be...Read more -
What Is Calcium Glycerophosphate Used For?
Calcium glycerophosphate (CAS 27214-00-2) supplies calcium and phosphorus in a single ingredient. It is used in mineral formulations and has been studied in fluoride toothpaste. Its value in each application depends on different properties. In nutrition, elemental mineral content matters. In too...Read more -
Capsaicin in Food Formulation
Capsaicin is a major source of the heat in chili peppers. In food formulation, chili powder, pastes and capsicum oleoresins deliver that heat in different forms. The right form depends on the desired chili character, the way the ingredient distributes through the food and the heat consumers perc...Read more -
