Amphoteric Surfactants
Amphoteric surfactants are unique surface-active agents that can act as either anionic or cationic surfactants depending on the pH of the solution. These molecules contain both acidic (carboxyl or sulfonic) and basic (amine or quaternary ammonium) functional groups, giving them high versatility, mildness, and compatibility with other surfactants. Amphoteric surfactants are widely used in personal care, household cleaning, industrial applications, pharmaceuticals, and specialty formulations where low irritation and effective cleansing are critical. Common examples include Cocamidopropyl Betaine and Lauryl Betaine.
Basic Laundry Detergent
Basic Laundry Detergent is a cleaning agent formulated primarily for washing textiles such as clothes, linens, and other fabrics. It typically contains surfactants, builders, enzymes, and other additives that work synergistically to remove dirt, stains, and odors from fabrics. Designed for household and industrial use, laundry detergents help restore fabric cleanliness and freshness while maintaining fiber integrity. Basic laundry detergents can be in powder, liquid, or tablet form, and are formulated to perform in various water hardness conditions and temperatures.
Diethanolamine
Diethanolamine is a colorless to pale yellow, viscous liquid with a mild ammonia-like odor. It is a secondary amine and diol, widely used in various industrial, pharmaceutical, and cosmetic applications. DEA is highly soluble in water and many organic solvents. It acts as an intermediate in the synthesis of surfactants, emulsifiers, corrosion inhibitors, and pharmaceuticals. It is valued for its alkalinity, emulsifying properties, and ability to form stable complexes with fatty acids.
Emulsifier ( Emulgator) NP-9
Emulsifier ( Emulgator) NP-9 is a nonionic surfactant belonging to the family of Nonylphenol Ethoxylates (NPEs), specifically with an average of 9 ethylene oxide (EO) units. It is widely used as an effective emulsifying, wetting, dispersing, and solubilizing agent. NP-9 is typically a pale yellow to amber viscous liquid, soluble in water and various organic solvents. It is valued for its strong emulsifying ability to stabilize oil-in-water (O/W) and water-in-oil (W/O) emulsions, excellent detergency, and good compatibility with other surfactants and formulation ingredients. NP-9 is commonly employed in industrial, agricultural, cosmetic, pharmaceutical, and cleaning applications.
Labsa
Labsa Ufacid, also known as Ufacid 90%, is a highly concentrated anionic surfactant widely used in the detergent and cleaning industries. It is a viscous, oily liquid or semi-solid with strong acidic properties and excellent surface-active capabilities.

Terrazzo Cleaner
Terrazzo Cleaner is a specialized, neutral to mildly alkaline cleaning formulation designed specifically for the safe and effective cleaning, restoration, and maintenance of terrazzo flooring. Terrazzo is a composite material consisting of marble, quartz, granite, glass, or other aggregate chips embedded in a cementitious or epoxy matrix, which is then ground and polished to a smooth surface. This cleaner is engineered to be non-acidic and non-etching to protect the calcareous (calcium-based) marble and limestone aggregates from chemical attack while effectively emulsifying and lifting embedded dirt, grime, oils, and stubborn stains. It penetrates the porous surface to release trapped contaminants without dulling the polished finish or degrading the grout lines. Industrial Grade Terrazzo Cleaner is formulated for daily, weekly, and restorative maintenance in high-traffic commercial, institutional, and residential settings. It is not intended for stripping heavy wax or polymer coating build-up unless specifically formulated for that purpose.
