Acticide
Acticide is a brand name for a range of biocides and preservatives used primarily in industrial and commercial products to prevent the growth of bacteria, fungi, algae, and other microorganisms. It is commonly added to paints, coatings, adhesives, plastics, and personal care products to extend their shelf life and maintain product quality.
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.
Concrete & cabro stain cleaner
Concrete & Cabro Stain Cleaner is a specialized, acidic cleaning formulation designed to remove stubborn stains, discoloration, and mineral deposits from concrete surfaces and cabro paving blocks (interlocking pavers). It is typically a liquid concentrate that works by chemically dissolving and lifting embedded grime, organic growth, and inorganic salts. This product is intended for heavy-duty industrial, commercial, and residential exterior cleaning and is not suitable for use on sensitive surfaces like marble, limestone, or certain metals, or for general household cleaning.
