Acticide
Acticide is a brand name for a range of biocides and preservatives used primarily in industrial and commercial products to prevent the growth of bacteria, fungi, algae, and other microorganisms. It is commonly added to paints, coatings, adhesives, plastics, and personal care products to extend their shelf life and maintain product quality.
Diethanolamine
Diethanolamine is a colorless to pale yellow, viscous liquid with a mild ammonia-like odor. It is a secondary amine and diol, widely used in various industrial, pharmaceutical, and cosmetic applications. DEA is highly soluble in water and many organic solvents. It acts as an intermediate in the synthesis of surfactants, emulsifiers, corrosion inhibitors, and pharmaceuticals. It is valued for its alkalinity, emulsifying properties, and ability to form stable complexes with fatty acids.
Fatty Acid
Fatty acids are a group of carboxylic acids consisting of long aliphatic chains, which can be either saturated or unsaturated. They are typically derived from natural fats and oils through hydrolysis or saponification and appear as colorless to pale yellow liquids or solids depending on the chain length and degree of saturation. Fatty acids are fundamental building blocks in biochemistry and industrial chemistry, serving as raw materials in the manufacture of soaps, detergents, lubricants, cosmetics, plastics, and food additives. Their amphiphilic nature—containing both hydrophilic (carboxyl group) and hydrophobic (alkyl chain) components—makes them versatile for various chemical and industrial applications.
Hypro
Hypro is a high-quality, non-ionic, water-soluble cellulose ether used primarily as a thickening, suspending, and stabilizing agent. It is derived from cellulose and chemically modified to achieve excellent water retention, rheological control, and film-forming properties. Hypro 88 is widely valued in industries such as construction, paints and coatings, adhesives, pharmaceuticals, and personal care for its ability to enhance texture, improve workability, and stabilize formulations.
Mono Ethanol Amine
Mono Ethanol Amine (MEA) is a clear, colorless, hygroscopic liquid with an ammonia-like odor. It is an organic chemical compound combining both amine and alcohol functional groups. MEA is widely used as a versatile chemical intermediate and is especially important in gas treatment, detergents, and chemical manufacturing due to its alkalinity and solubility in water and organic solvents.
Nonylphenol Ethoxylate
Nonylphenol Ethoxylate is a non-ionic surfactant belonging to the alkylphenol ethoxylate family, characterized by an average of 9 ethylene oxide units.
