Description

Fettsure, C16-C22 Und C18 Ungesttigt, Ethoxyliert (Eo 15-35 Mol) is a nonionic surfactant belonging to the class of ethoxylated fatty acids, specifically derived from a blend of C16-C22 saturated and C18 unsaturated fatty acids with an ethoxylation degree of 15-35 moles. This versatile chemical intermediate is valued for its excellent emulsifying, dispersing, and wetting properties, making it a critical component in formulating high-performance industrial products. Key industries that rely on this surfactant include agrochemicals, textile processing, metalworking fluids, and personal care, where consistent quality and reliable performance are paramount.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in the production of herbicides, insecticides, and fungicides, enhancing spray coverage and efficacy.
• Textile Auxiliaries: Used as a scouring, leveling, and softening agent in fiber processing and dyeing operations to improve fabric quality and color uniformity.
• Metalworking Fluids: Serves as an emulsifier and lubricity agent in coolants, cutting oils, and drawing compounds to improve tool life and surface finish.
• Personal Care & Cosmetics: Functions as a gentle emulsifier and thickener in creams, lotions, and hair care products, providing stable formulations.
• Industrial & Institutional Cleaners: Employed as a degreaser and dispersant in heavy-duty cleaning formulations for hard surfaces and equipment.
• Paints & Coatings: Used as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Leather Processing: Aids in fatliquoring and dyeing processes, improving the softness and uniformity of leather goods.
• Paper & Pulp Industry: Acts as a deinking agent and dispersant in recycling processes and paper coating formulations.

Quality Control

Our Fettsure, C16-C22 Und C18 Ungesttigt, Ethoxyliert (Eo 15-35 Mol) is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure compliance with agreed specifications for parameters such as hydroxyl value, acid value, saponification value, and ethoxylate distribution. Certificates of Analysis (COA) documenting these results are available upon request, providing full traceability and assurance of product consistency for your critical applications.

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/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents.
