Potassium Methoxysalicylate

Synonyms: Potassium 2-methoxysalicylate, Potassium 2-hydroxy-3-methoxybenzoate, Potassium o-vanillate, Potassium 3-methoxysalicylate, 2-Methoxysalicylic acid potassium salt, Potassium 2-hydroxy-3-methoxybenzoate

Potassium Methoxysalicylate is the potassium salt of 2-methoxysalicylic acid (also known as o-vanillic acid), a substituted salicylic acid derivative. It appears as a white to off-white crystalline powder, freely soluble in water and lower alcohols, and is typically supplied at ≥99.0% purity (HPLC). The compound is produced via methylation of salicylic acid followed by neutralization with potassium hydroxide, yielding a stable, non-hygroscopic salt that is easy to handle in aqueous formulations.

In the personal care and pharmaceutical industries, Potassium Methoxysalicylate is valued as a mild, water-soluble salicylate that delivers exfoliating and anti-inflammatory benefits without the irritation profile of harsher acids. It also serves as a versatile intermediate in organic synthesis, particularly in the preparation of flavanone and flavonoid derivatives, and finds use as a preservative booster in cosmetic systems. Its potassium salt form ensures rapid dissolution and compatibility with a wide range of pH conditions.
