Description

p-Dodecylbenzenesulphonic Acid, Compound With 1-Aminopropan-2-Ol (1:1) is a high-purity, neutralized salt form of dodecylbenzenesulfonic acid (DBSA) offering enhanced handling characteristics. This compound is valued for its dual functionality, combining the surfactant properties of a sulfonic acid with the solubility and stability imparted by the alkanolamine. It is essential for formulators in the detergent, personal care, and industrial cleaning sectors who require a consistent, low-dusting, and readily soluble active ingredient.

Application

• Primary Surfactant/Detergent Base in liquid and powder laundry detergents, dishwashing liquids, and all-purpose cleaners.
• Emulsifier and Stabilizer in emulsion polymerization for producing synthetic rubbers, resins, and polymer dispersions.
• Acid Catalyst Neutralizer in various chemical synthesis processes where a non-corrosive, soluble sulfonate is needed.
• Additive in Personal Care formulations such as shampoos and body washes, where its salt form offers mildness and compatibility.
• Wetting and Dispersing Agent in agricultural formulations, coatings, and textile processing aids.
• Intermediate for the synthesis of other specialty surfactants and sulfonated compounds.

Quality Control

Our p-Dodecylbenzenesulphonic Acid, Compound With 1-Aminopropan-2-Ol (1:1) is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for assay, moisture content, color, and impurity profiles. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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); ensure containers are kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which can lead to caking or changes in physical properties.
