OS-15 (AEO-15) is widely used in many industries such as cleaning, textile, papermaking, leather, metal processing, cosmetics, and pesticides, functioning as a nonionic surfactant with core functions including emulsification, dispersion, wetting, and solubilization.

Detailed Description

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.

Main Application Industries and Processes

Application IndustrySpecific Process/UseFunction Description
Industrial and Household CleaningLaundry detergent, dishwashing detergent, hard surface cleaning formulationsAs a high-efficiency nonionic surfactant, significantly improves detergency, emulsification, and dispersion ability
Textile Printing and DyeingLeveling agentWith excellent penetration and leveling properties, helps dyes evenly deposit on fibers, reducing color spots and color differences, improving dyeing quality
Paint, Ink, Dye ProcessingDispersantHas good dispersion and stabilization effects on solid particles such as pigments and fillers, preventing agglomeration and settling
Papermaking IndustryDeinking agentPromotes ink detachment and emulsification dispersion during waste paper deinking, improving fiber yield and pulp brightness
Leather ProcessingSoaking, degreasing, fatliquoring, etc.Enhances penetration and emulsification effects, making leather soft and plump with excellent hand feel
Metal Surface TreatmentSurface cleanerEffectively removes contaminants such as oil, cutting fluids, and polishing pastes from metal surfaces; works better with ultrasonic or spray cleaning
CosmeticsO/W emulsifier for creams and lotionsProvides a fine and stable emulsion system, giving good spreadability and skin feel
PesticidesEmulsifier and wetting agentImproves dispersion and wetting spreading ability of active ingredients in water, enhancing adhesion and penetration of the spray liquid on plant leaves and insect surfaces

Application Suggestions

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.

Precautions

  • This product is classified as causing skin irritation (H315) and serious eye irritation (H319). During operation, be sure to wear impermeable gloves (e.g., nitrile gloves) and chemical safety goggles.
  • Avoid discharging undiluted or large quantities of product directly into water bodies or sewers to prevent chronic hazards to the aquatic environment (H412).
  • The storage temperature should be maintained between 5 and 35°C, avoiding freezing and excessively high temperatures. Keep containers tightly closed, away from strong oxidizing agents, strong acids, and strong bases.
  • In case of skin or eye contact, rinse immediately with plenty of running water for at least 15 minutes and seek medical attention if necessary.
