Description

Soap CAS NO 8029-38-7 refers to a traditional cleansing agent, typically a sodium or potassium salt of fatty acids derived from natural oils or fats. This versatile compound is valued for its surfactant properties, which enable effective emulsification, cleaning, and degreasing across numerous industrial and commercial processes. It serves as a foundational ingredient for manufacturers in the personal care, textile, metalworking, and institutional cleaning sectors seeking reliable and biodegradable performance.

Application

• Personal Care & Cosmetics: Primary surfactant in traditional bar soaps, liquid hand soaps, and shaving creams.
• Textile Processing: Used as a scouring agent to remove natural oils, waxes, and impurities from fibers like wool and cotton.
• Metalworking & Industrial Cleaning: Acts as an emulsifier and degreaser in cutting fluids, rust preventatives, and heavy-duty cleaner formulations.
• Institutional & Household Cleaning: Key component in laundry soaps, dishwashing detergents, and all-purpose cleaners.
• Pharmaceuticals: Employed as an excipient in certain medicated soaps and ointments for its emulsifying and cleansing action.
• Lubricant & Release Agent: Functions as a lubricant in wire drawing and as a mold release agent in various manufacturing processes.

Quality Control

Our Soap is produced under strict quality management systems to ensure batch-to-batch consistency and performance. Quality parameters such as total fatty matter, free alkali, moisture content, and unsaponifiable matter are rigorously tested. Certificates of Analysis (COA) documenting compliance with relevant specifications, including FCC for food-grade variants or in-house technical standards, are available upon request.

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 material is hygroscopic (moisture-sensitive) and should be kept away from strong acids and strong oxidizing agents to prevent decomposition.
