Description

Potassium 3-Hydroxypropanesulphonate is an organosulfonate salt valued for its unique combination of a hydroxyl group and a sulfonate moiety. This bifunctional structure makes it a versatile intermediate and additive, particularly effective as a hydrotrope and solubilizing agent. It is primarily sought by manufacturers in the personal care, detergent, and specialty chemical industries for formulating high-performance products.

Application

• Personal Care Formulations: Acts as a hydrotrope and viscosity modifier in clear gels, shampoos, and body washes, enhancing the solubility and stability of active ingredients.
• Detergent & Cleaning Products: Used as a solubilizer and coupling agent in liquid detergents and hard-surface cleaners to improve phase stability and cloud point.
• Chemical Synthesis: Serves as a key sulfonation intermediate and building block for synthesizing more complex surfactants and specialty chemicals.
• Textile & Leather Processing: Functions as a dyeing auxiliary and leveling agent to promote even color uptake and improve process efficiency.
• Water Treatment: Employed as a scale inhibitor and dispersant in cooling water and boiler water systems.
• Pharmaceutical Intermediates: Utilized in the synthesis of certain active pharmaceutical ingredients (APIs) requiring sulfonate functionality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
