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.
Clear Emulsion
Clear Emulsion is a transparent or translucent mixture of two immiscible liquids—typically oil and water—stabilized by emulsifying agents to form a stable, homogenous system. This product is widely used in cosmetics and personal care, pharmaceuticals, and specialty industrial applications due to its lightweight texture, ease of absorption, and aesthetic appeal. Clear emulsions offer a visually appealing, non-greasy feel with the advantages of both oil and water phases, delivering moisturizing, protective, and active ingredient-carrying benefits. Their clarity distinguishes them from traditional creamy emulsions, making them popular in modern skincare and cosmetic formulations.
Cocamino Propyl Betaine Desmocol
Cocamino Propyl Betaine Desmocol is a mild amphoteric surfactant derived from coconut oil fatty acids and amino acids. It appears as a clear to slightly hazy liquid with a faint coconut-like odor. CAPB is widely used in personal care and household cleaning products for its excellent foaming, cleansing, and conditioning properties. Being a zwitterionic surfactant, it is compatible with anionic, cationic, and nonionic surfactants, enhancing the mildness and stability of formulations. The 30% active solution is easy to handle and incorporate in various cosmetic and detergent products. It functions as a foam booster, viscosity builder, and anti-irritant agent, making it a versatile ingredient in mild formulations.
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.
Emulsifying Wax Anionic
Emulsifying Wax Anionic is a versatile surfactant blend composed primarily of fatty alcohols (such as cetyl or stearyl alcohol) and anionic surfactants like sodium lauryl sulfate. It is designed to stabilize oil-in-water (O/W) emulsions by reducing interfacial tension between water and oil phases. It appears as white to off-white solid flakes or pellets, with a mild fatty odor and is dispersible in water with agitation and mild heat. Known for its excellent emulsification, cleansing, and thickening properties, this emulsifying wax is widely used in cosmetics, pharmaceuticals, household cleaners, and industrial applications.
Myristic Acid
Myristic Acid is a saturated fatty acid with a 14-carbon chain, naturally found in nutmeg, coconut oil, palm kernel oil, and butter fat. It appears as a white crystalline solid with a faint odor. It is widely used in the manufacture of soaps, cosmetics, surfactants, and food additives due to its emollient and cleansing properties. Myristic Acid acts as a key intermediate in the production of esters, detergents, and lubricants.
Oleic Acid
Oleic Acid is a naturally occurring monounsaturated fatty acid commonly derived from vegetable oils such as olive, sunflower, and canola oils. This oily liquid is widely used in the chemical, pharmaceutical, cosmetic, and food industries due to its excellent emollient, surfactant, and stabilizing properties. Oleic Acid 75% is a key raw material in manufacturing soaps, detergents, lubricants, and personal care products. Its amphiphilic nature makes it an effective emulsifier and penetration enhancer.
Polyglycerol-10-Laurate
Polyglycerol-10-Laurate is a non-ionic, biodegradable surfactant and emulsifier derived from natural lauric acid and polyglycerol (with ten glycerol units). It is known for its excellent emulsifying, dispersing, and solubilizing properties, especially in oil-in-water systems. Commonly used in cosmetics, food, pharmaceuticals, and personal care products, it is valued for being mild, non-toxic, and suitable for sensitive applications, including baby care and oral care.
