OS-15 (AEO-15) is chemically named fatty alcohol polyoxyethylene (15) ether, belonging to the nonionic surfactant category. The product appears as a white waxy solid and, thanks to its excellent emulsifying ability, superior wetting and dispersing properties, outstanding solubilization effect, and strong resistance to acids, alkalis, and hard water, has become an indispensable functional additive in many industrial fields.
The outstanding advantage of this product lies in its broad compatibility, allowing it to be compounded with anionic, cationic, and other nonionic surfactants to produce synergistic effects, which demonstrates extremely high application flexibility in complex formulation systems. Meanwhile, it maintains structural integrity and performance stability over a wide pH range, enabling it to adapt to various harsh working conditions.
| Application Industry | Specific Process/Use | Function Description |
|---|---|---|
| Industrial and Household Cleaning | Laundry detergent, dishwashing detergent, hard surface cleaning formulations | As a high-efficiency nonionic surfactant, significantly improves detergency, emulsification, and dispersion ability |
| Textile Printing and Dyeing | Leveling agent | With excellent penetration and leveling properties, helps dyes evenly deposit on fibers, reducing color spots and color differences, improving dyeing quality |
| Paint, Ink, Dye Processing | Dispersant | Has good dispersion and stabilization effects on solid particles such as pigments and fillers, preventing agglomeration and settling |
| Papermaking Industry | Deinking agent | Promotes ink detachment and emulsification dispersion during waste paper deinking, improving fiber yield and pulp brightness |
| Leather Processing | Soaking, degreasing, fatliquoring, etc. | Enhances penetration and emulsification effects, making leather soft and plump with excellent hand feel |
| Metal Surface Treatment | Surface cleaner | Effectively removes contaminants such as oil, cutting fluids, and polishing pastes from metal surfaces; works better with ultrasonic or spray cleaning |
| Cosmetics | O/W emulsifier for creams and lotions | Provides a fine and stable emulsion system, giving good spreadability and skin feel |
| Pesticides | Emulsifier and wetting agent | Improves dispersion and wetting spreading ability of active ingredients in water, enhancing adhesion and penetration of the spray liquid on plant leaves and insect surfaces |
In formulation design, OS-15 (AEO-15) is often used in combination with other types of surfactants to achieve synergistic effects. For example, combining with anionic surfactants (such as LAS, AES) in detergent formulations can improve detergency and foam performance; compounding with nonionic or anionic emulsifiers in pesticide formulations can optimize emulsion stability. It is recommended to determine the optimal dosage through HLB value matching and experimental optimization based on specific process requirements.
If the product freezes before use, it can be thawed naturally at room temperature and then used normally; do not heat with an open flame. Since this product is a waxy solid, it is recommended to pre-melt it or dissolve it in warm water during batching for easy handling and uniform dispersion.
