MOA-23 (AEO-23) is a non-ionic fatty alcohol polyoxyethylene ether surfactant with a high degree of polymerization. It appears as a white waxy solid and is widely used in fields such as textile printing and dyeing, industrial cleaning, household washing, cosmetics, leather processing, papermaking, and emulsion polymerization.
Detailed Description
MOA-23 (AEO-23), with the chemical name fatty alcohol polyoxyethylene ether and CAS number 68439-50-9, belongs to the non-ionic surfactant category. It has many aliases, including Laureth-23, C12~14 Alcohol Polyoxyethylene (23) Ether, Peregal O-23, Leveling Agent O-23, Emulsifier O-23, etc. This product is formed by the addition polymerization of C12~C14 fatty alcohols with approximately 23 ethylene oxide (EO) molecules, resulting in a high degree of polymerization and an HLB value of about 16~17. It is a typical oil-in-water (O/W) emulsifier.
MOA-23 possesses several outstanding performance characteristics: excellent emulsifying ability, capable of forming stable and fine emulsion systems; superior wetting and dispersing properties, enhancing formulation uniformity; strong resistance to acids, alkalis, and hard water, maintaining high efficiency and stability under complex water quality conditions; a high cloud point makes it suitable for high-temperature operating environments; it also exhibits good compatibility with anionic, cationic, and amphoteric surfactants, offering high formulation flexibility.
This product has a high active content ensuring usage efficiency, which can reduce the required dosage; a mild feel makes it suitable for personal care product development; it has good biodegradability, aligning with environmental trends. In terms of safety, it is classified under GHS as Skin Irritation Category 2 and Serious Eye Irritation Category 2A, requiring the use of protective gloves and goggles during handling.

Application Recommendations
MOA-23 (AEO-23), with its high HLB value and excellent emulsifying performance, has broad application value in multiple industries:
- Textile Printing and Dyeing: As a leveling agent and dispersant, it effectively prevents dye aggregation, ensuring uniform dyeing of fabrics, especially suitable for high-temperature and high-pressure dyeing processes.
- Industrial Cleaning: As a core component of hard surface cleaners and metal degreasers, it quickly removes heavy oil stains and carbon deposits from metal surfaces.
- Household Washing: Provides excellent emulsifying, detergency, and anti-redeposition properties in laundry liquids and powders, enhancing overall washing performance.
- Cosmetics and Personal Care: As an O/W emulsifier and solubilizer, it can be used in creams, lotions, and other products, as well as for solubilizing hydrophobic ingredients such as fragrances and essential oils.
- Leather Processing: Effectively removes natural oils from raw hides and imparts good wetting and penetration abilities during wet processing.
- Papermaking Industry: Separates and removes ink particles during wastepaper deinking, improving pulp whiteness and deinking efficiency.
- Emulsion Polymerization: Provides stable emulsification for acrylic ester, styrene-acrylic, and other emulsion polymerization systems, yielding polymer emulsions with uniform particle size and good storage stability.
Precautions
- This product is classified as Skin irritant (H315) and Serious eye irritant (H319). Always wear protective gloves and eye protection/face shield during handling.
- Wash hands thoroughly after handling (P264). If in eyes, rinse cautiously with water for several minutes, remove contact lenses if present and continue rinsing (P305+P351+P338).
- During high-temperature seasons, the product may soften, which is a normal physical change and does not affect product quality.
- Keep in sealed packaging, store in a cool, dry, and well-ventilated place away from strong oxidizers. Recommended storage temperature: 5°C to 40°C.
- Low toxicity to aquatic organisms (Fish LC50 >10-100 mg/L), but still avoid direct discharge into water bodies or drains.
