Benzoic Acid
Benzoic Acid is a white crystalline solid with a faint, pleasant odor, classified as a simple aromatic carboxylic acid. It is widely used as a food preservative, antimicrobial agent, and chemical intermediate. Naturally occurring in many plants, it is commercially produced through oxidation of toluene or extraction from natural sources. Benzoic acid is valued for its ability to inhibit the growth of mold, yeast, and certain bacteria, making it essential in food preservation and cosmetic formulations. It also serves as a precursor in the manufacture of various pharmaceuticals, dyes, and plasticizers.
Benzyl Konium Chloride
Benzyl Konium Chloride (BAC) 50% is a quaternary ammonium compound with potent antimicrobial and disinfectant properties. It is a cationic surfactant widely used for its bactericidal, fungicidal, and virucidal effects. This clear to pale yellow liquid concentrate is highly soluble in water and is commonly used in healthcare, sanitation, and industrial hygiene applications. BAC 50% solutions serve as active ingredients in disinfectants, sanitizers, and antiseptics due to their effectiveness against a broad spectrum of microorganisms.
Citric Acid Anhydrous
Citric Acid Anhydrous is a white, crystalline organic acid widely used across food, pharmaceutical, cosmetic, and industrial sectors. It is the anhydrous form of citric acid, meaning it contains no water molecules in its crystal lattice, resulting in higher purity and more concentrated acidic properties compared to its monohydrate form. Derived from natural sources like citrus fruits or produced via microbial fermentation, citric acid anhydrous is valued for its sour taste, excellent chelating ability, and buffering capacity. It serves as a natural preservative, pH adjuster, antioxidant synergist, and cleaning agent, making it a versatile ingredient in many formulations.
Indion Cation Resin
Indion Cation Resin is a synthetic ion exchange resin designed primarily for the removal of positively charged ions (cations) from water and various liquid streams. Typically composed of a sulfonated polystyrene-divinylbenzene (PS-DVB) copolymer, this resin features a highly porous bead structure with functional groups that exchange hydrogen or sodium ions for calcium, magnesium, iron, and other metallic cations. Available in different forms (strong acid cation, weak acid cation), Indion Cation Resin is widely used in water treatment, industrial processes, and purification systems.
Sodium Propyl Paraben
