MOA-7 (AEO-7), chemical name fatty alcohol polyoxyethylene (7) ether (CAS No.: 68439-50-9), is a nonionic surfactant formed by condensation of C12-14 fatty alcohols with 7 moles of ethylene oxide. The product appears as a colorless to slightly yellow transparent liquid or white paste (state varies with temperature), also known as laureth-7, polyoxyethylene (7) lauryl ether, etc. Its molecular structure, combining hydrophilic polyoxyethylene chains and hydrophobic long-chain alkyl groups, endows the product with excellent versatility.
MOA-7 offers four key advantages in applications:
As an efficient nonionic surfactant, MOA-7 is a key active component in household laundry liquids, dishwashing detergents, and industrial heavy-duty cleaners, providing excellent detergency, emulsification, and dispersion.
With outstanding wetting and penetrating abilities, MOA-7 is used as a leveling agent and penetrating agent, ensuring uniform dye diffusion within fibers, preventing uneven dyeing, and improving dye uptake and dyeing quality.
As an efficient leather degreasing agent, MOA-7 effectively removes natural oils and dirt from raw hides, accelerates the soaking process, and provides a clean fiber environment for subsequent tanning and fatliquoring processes.
In metal hard surface cleaners, MOA-7 strongly removes mineral oils, polishing waxes, and cutting fluids from metal parts, while also offering anti-rust and corrosion inhibition functions, suitable for spray and immersion industrial cleaning.
As an emulsifier and solubilizer, MOA-7 is used in creams, lotions, cleansing oils, etc., to build stable oil-in-water emulsions, and effectively solubilizes oil-soluble ingredients such as fragrances and essential oils.
MOA-7 acts as a pesticide emulsifier, dispersing hydrophobic pesticide technical materials uniformly in an aqueous medium to form highly stable emulsion or microemulsion formulations, enhancing the wetting and spreading of the spray on plant leaves, thus improving efficacy.
In the synthesis of acrylate or styrene-butadiene latex, MOA-7 serves as an emulsifier providing micellar nucleation sites, controlling polymerization rate, and ensuring mechanical and storage stability of the final latex.
In the deinking process of waste paper, MOA-7, through its penetrating and emulsifying action, quickly separates and suspends ink particles from waste paper, preventing re-deposition of ink, and improving the whiteness and yield of recycled pulp.
In drilling fluids and produced fluid treatment, MOA-7 acts as an emulsifier, viscosity reducer, or paraffin inhibitor, improving oil-water interfacial tension and enhancing oil recovery and transportation efficiency.
MOA-7 is classified as a low-toxicity substance, but appropriate protective measures should be taken during handling:
It is recommended to operate in well-ventilated areas, store in a cool, dry, well-ventilated warehouse, keep containers tightly closed, and keep away from strong oxidizing agents and strong acids/bases. For detailed safety information, please refer to the Safety Data Sheet (SDS).
