Peregal O-20 (C16-18 fatty alcohol polyoxyethylene (20) ether) is a high-performance nonionic surfactant. Due to its excellent emulsifying ability, wide pH tolerance (resistance to acids and alkalis), outstanding hard water resistance, and good compatibility, it has become an indispensable functional additive in multiple industrial fields. Its nonionic nature allows it to be compounded with anionic, cationic, and amphoteric surfactants, resulting in significant synergistic effects and a wide range of applications.
In different industry processes, Peregal O-20 plays distinct key roles: as an efficient leveling agent in textile printing and dyeing; as a stable emulsifier in pesticide formulations; as an O/W emulsifier and solubilizer in daily chemicals; as a powerful decontamination component in cleaning products; and as an efficient penetrating and wetting agent in metal processing, papermaking, and leather treatment.
As a leveling agent and dispersant, Peregal O-20 is used in textile dyeing processes. It effectively slows down the dyeing rate, promotes uniform distribution of dyes on the fiber surface, prevents dyeing defects such as uneven color and stains, and ensures full and uniform fabric color. It has a good affinity for direct dyes and vat dyes, and can effectively disperse dyes and pigments, improving dyeing uniformity and color fastness.
As an emulsifier, Peregal O-20 is used in the preparation of pesticide emulsion in water (EW) and microemulsion (ME). It significantly reduces the oil-water interfacial tension, forming a stable work emulsion with good dilution properties, thereby improving the utilization rate of pesticide active ingredients and field efficacy.
Used as an O/W (oil-in-water) emulsifier and solubilizer in products such as creams, lotions, and shampoos. As a primary or auxiliary emulsifier, it forms a stable oil-in-water system, giving the cream a delicate and shiny texture; simultaneously, it can solubilize oily fragrances and active ingredients into the water system, enhancing product transparency and usage feel.
As a decontamination functional component, Peregal O-20, with its excellent wetting, penetration, and emulsification triple action, quickly removes and disperses oil stains and sweat stains on fabric fibers and hard surfaces, significantly improving the cleaning effect of liquid detergent products.
Used as a penetrant and wetting agent in metal cutting, grinding, and other processing operations. It quickly reduces the surface tension of processing fluids, improves the wetting effect of the liquid on metal surfaces, and enhances cooling and lubrication efficiency.
As a penetration and dispersion aid, it improves slurry uniformity and paper quality, promoting uniform coating distribution during paper coating processes.
Used as a penetration aid in processes such as soaking and fatliquoring, it facilitates the penetration of treatment solutions into the leather interior, enhancing the softness and hand feel of the leather, and improving the quality of the finished product.
