INTRODUCTION
Potassium benzoate (E212), the potassium salt of benzoic acid, is a food preservative used to prevent the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid.
MANUFACTURE
Potassium benzoate is produced by oxidizing toluene to benzoic acid followed by a neutralization with potassium hydroxide.

Tert-Amyl Alcohol (TAA) also known as 2-Methyl-2-butanol, is a branched-chain alcohol. It is a colorless, flammable liquid with a mild alcoholic odor and moderate water solubility. Due to its unique structural properties, it is widely used as basic organic chemical in synthetic fragrances, pharmaceuticals and pigment industries.
Lithium orotate is a compound consisting of lithium, an alkali metal, and orotic acid, a natural substance involved in nucleic acid metabolism. It is a popular dietary supplement due to its potential neuroprotective and mood-stabilizing effects.
Quinuclidinone Hydrochloride is a derivative of bicyclic amine quinuclidine. The hydrochloride form of quinuclidinone is the salt form, often used for its stability in different reactions. Quinuclidinone Hydrochloride is typically used as an intermediate in the synthesis of various pharmaceuticals and other chemical products.
n-Hexyllithium in hexane solution (HxLi) is an organolithium compound primarily used in organic synthesis as a strong base, alkylating agent, and lithiation reagent. It is particularly effective in the deprotonation of weakly acidic compounds. Handling n-Hexyllithium requires strict safety precautions due to its highly reactive nature, particularly due to its sensitivity to moisture, air, and heat.
2,4-Dichlorobenzyl alcohol (DCBA) is a member of the class of Benzyl alcohols in which the hydrogens at positions 2 and 4 are replaced by chlorines.
Its effectiveness against a broad spectrum of pathogens makes it a valuable ingredient in antiseptic products.
Ethylhexylglycerin is typically a clear, colorless liquid used in personal care products, as a preservative and a conditioning agent. It’s approved for use in cosmetics by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Union (EU).
N-acetylsulfanilyl chloride is a white coloured powder, soluble in organic solvents and slightly soluble in water. It is a versatile chemical compound that has numerous applications in industries, such as Agro and Pharmaceuticals.
Fir Needle Essential Oil is obtained from the fir needles of the Siberian fir tree Abies sibirica, belonging to the plant family of Pinaceae. The oil has a fresh, green, woody, and balsamic fragrance due to which it is generally used as a fragrance ingredient in soaps and perfumes.
2-Benzoylbenzoic Acid is an organic compound featuring a benzoyl group attached to a carboxylic acid group, commonly used as an intermediate in the synthesis of pharmaceuticals, dyes, and polymers, as well as for its photochemical properties in UV-absorbing formulations.
