Laureth Phosphate MOA-3P is an anionic surfactant that combines strong emulsifying power, excellent penetrability, and mild low-irritation properties. Due to its molecular structure containing both phosphate ester groups and polyoxyethylene ether chains, it excels in multiple fields such as personal care, industrial cleaning, and textile printing and dyeing.

Detailed Description

Laureth Phosphate MOA-3P (chemical name: Laureth-3 Phosphate) appears as a colorless to light yellow transparent liquid and belongs to the anionic surfactant category. The unique synergistic effect of the phosphate ester groups and polyoxyethylene ether chains in its molecular structure endows the product with excellent interfacial activity and broad compatibility, maintaining stable surface activity under harsh conditions such as acidic, alkaline, and high-concentration salt solutions.

This product has six core advantages: First, it has strong emulsifying power for various oils, waxes, and organic phases, significantly reducing oil-water interfacial tension and forming stable and fine emulsion systems; Second, it can quickly spread on solid surfaces with excellent wetting and penetrability, standing out in textile and industrial cleaning fields; Third, it has outstanding electrolyte tolerance and chemical stability, adapting to high-strength conditions such as acids, bases, and salts; Fourth, it can maintain effective cleaning and emulsifying effects even in hard water with high calcium and magnesium ion content, and is not prone to forming calcium soap deposits; Fifth, with reasonable formulation, it has low irritation to the skin and mucous membranes, suitable for fields with high safety requirements such as personal care; Sixth, it can be widely compounded with nonionic, anionic, and amphoteric surfactants to exert synergistic effects.

With the above characteristics, MOA-3P is widely used in personal care products such as shampoos, shower gels, and facial cleansers as a mild anionic surfactant and thickener. It is also used in household and industrial hard surface cleaners, textile pretreatment scouring agents and penetrants, metalworking fluid emulsifying and anti-rust components, pesticide formulation emulsifying dispersants, and reactive emulsifiers in emulsion polymerization.

Application Suggestions

Personal Care Products: As a mild anionic surfactant and thickening aid, it is recommended for use in systems such as shampoos, shower gels, and facial cleansers. It can provide fine foam and refreshing skin feel while reducing the overall irritation of the formulation and improving product consistency and stability.

Household and Industrial Cleaning: Leveraging excellent penetration, emulsification, and degreasing capabilities, it is suitable for removing oil stains from hard substrates such as metals, glass, and ceramics, playing a key role in kitchen cleaning and industrial degreasing formulations.

Textile Printing and Dyeing: Used as a scouring agent and penetrant in pretreatment processes such as desizing, scouring, and bleaching, it accelerates the penetration of working fluids, improves impurity removal efficiency, and can impart temporary antistatic properties to fibers for subsequent processing.

Metalworking Fluids: As an emulsifier, it stably disperses base oil in water while providing anti-rust protection, suitable for cutting fluids, grinding fluids, and rolling fluid systems.

Pesticide Formulations: As an emulsifying dispersant, it allows oil-phase pesticide active ingredients to form stable emulsions in aqueous media, ensuring spontaneous emulsification and uniformity of the spray solution during field dilution.

Emulsion Polymerization: As a reactive anionic emulsifier, it participates in the monomer emulsification and latex particle stabilization of systems such as acrylates and styrene-acrylic, imparting excellent mechanical and chemical stability to the polymer emulsion.

Precautions

  • Skin Irritation: H315 (Causes skin irritation) — It is recommended to wear impermeable gloves (e.g., butyl rubber or nitrile rubber gloves) during operation.
  • Serious Eye Irritation: H319 (Causes serious eye irritation) — Chemical safety goggles must be worn during operation.
  • In case of skin contact, immediately wash with plenty of water and soap for at least 15 minutes; in case of eye contact, rinse eyes with water while holding eyelids open for at least 15 minutes and seek medical attention as soon as possible.
  • The product should be stored in a cool, dry, and well-ventilated warehouse. The container must be sealed promptly after use to avoid moisture absorption and contamination.
  • Keep away from heat sources, ignition sources, and incompatible materials. It is recommended to store at room temperature and avoid extreme temperatures.
  • For specific operation guidelines, please refer to the Safety Data Sheet (SDS).
