Standardized Potassium Hydroxide – High-Quality Alkalizing and pH-Adjusting Excipient from India

1. General Introduction to Potassium Hydroxide

Potassium Hydroxide (KOH), commonly known as caustic potash, is a highly alkaline inorganic compound. Outstanding for its excellent water solubility (an exothermic reaction) and rapid acid neutralization capability, this raw material is widely used as a pH-adjusting excipient and alkalizing agent in liquid medicines and injections, as well as a foundational chemical in Active Pharmaceutical Ingredient (API) synthesis and medical soap manufacturing.

The raw material is manufactured by Sujata Nutri-Pharma Pvt. Ltd. (India), one of the reputable pharmaceutical chemical and excipient manufacturers holding international quality certifications. With an advanced production and purification process, Sujata's Potassium Hydroxide achieves optimal purity, strictly controlling carbonate impurities and heavy metals. This ensures absolute consistency across production batches and fully complies with the most stringent global pharmacopeial standards.

2. Potassium Hydroxide Raw Material Information

• Raw Material Name: Potassium Hydroxide
• Manufacturer: Sujata Nutri-Pharma Pvt. Ltd.
• Origin: India
• Material Category: Pharmaceutical Excipient / Food Additive.
• Function: pH adjuster, alkalizing agent, catalyst, saponifying agent.
• Chemical Composition: Inorganic compound with the chemical formula KOH.
• Physical Form: White flakes, pellets, or lumps; highly hygroscopic (deliquesces when exposed to air) and highly corrosive in concentrated form.
• Solubility: Very soluble in water (releasing a large amount of heat), highly soluble in ethanol and glycerol, practically insoluble in ether.
• Quality Standards: Complies with the United States Pharmacopeia (USP), European Pharmacopoeia (EP), British Pharmacopoeia (BP), or Indian Pharmacopoeia (IP).

The raw material is strictly controlled for:

• Carbonate and Impurity Limits: Strict control of Potassium Carbonate (K₂CO₃) content generated by moisture absorption, along with heavy metal impurities (Arsenic, Lead, Sodium) at extremely low levels, well below international pharmacopeial thresholds.
• Purity (Assay): Ensures a high standard of total alkalinity (typically between 85% - 100.5% depending on the hydrated or anhydrous form), providing precise neutralization and pH adjustment capabilities.
• Microbiological Limits: Meets stringent microbiological standards for excipients used in pharmaceutical preparations.

3. Key advantages of Potassium Hydroxide 

• High Purity, Low Impurity Limits: Sujata's purification process maximizes the elimination of insoluble residues and heavy metals, particularly controlling carbonate cross-contamination effectively, which helps maintain clear solutions upon mixing.
• Outstanding pH Adjustment Efficiency: As a strong base, KOH helps adjust the pH of pharmaceutical solutions to the desired level rapidly and stably with just a very small amount.
• Versatile Application Properties: Not only used as an excipient, but the product also has high reactivity, making it ideal as a reactant in the chemical synthesis of Active Pharmaceutical Ingredients (APIs) or the production of specialized Potassium salts.
• Reasonable Cost and Stable Supply: Being manufactured in India by Sujata Nutri-Pharma allows the product to have an optimally competitive price, providing an effective solution for pharmaceutical and cosmetic manufacturing plants to optimize their product costs.

4. Applications of Potassium Hydroxide

In Pharmaceuticals (Core Application)

• pH Adjuster & Alkalizer: Used as an excipient to neutralize acid, adjust, and stabilize pH in liquid drug formulas (syrups, suspensions), eye drops, and intravenous injections.
• Pharmaceutical Synthesis: Used as an alkaline solvent, catalyst, or reactant in the synthesis of Active Pharmaceutical Ingredients (APIs) and chemical intermediates.

In Cosmetics & Food

• Soap and Detergent Manufacturing: Acts as the primary saponifying agent to produce soft soaps, liquid soaps, body washes, and shaving foams (creating potassium salts of fatty acids that are more soluble than sodium salts).
• Food Additive (E525): Acts as an acidity regulator, stabilizer, and thickener in food processing (such as in cocoa and chocolate processing, or peeling fruits).
