Lauryl ether phosphate MOA-3P is widely used in six major industries: personal care, industrial cleaning, textile printing and dyeing, metal processing, pesticide formulations, and emulsion polymerization. It is a multifunctional anionic phosphate surfactant.

Detailed Description

Lauryl ether phosphate MOA-3P (chemical name: lauryl polyoxyethylene ether phosphate) exhibits excellent emulsifying and dispersing capabilities, superior wetting and penetration properties, as well as outstanding resistance to electrolytes and hard water, thanks to the phosphate group and polyoxyethylene ether chain segments present in its molecular structure. These characteristics make it an irreplaceable component in various industrial fields and process stages.

In terms of mildness and compatibility, MOA-3P has low irritation to skin and mucous membranes when properly formulated, and can be widely compounded with nonionic, anionic, and amphoteric surfactants to produce synergistic effects. At the same time, it maintains good surface activity and structural stability in acidic, alkaline, and high-concentration salt solutions, making it suitable for formulation requirements under various harsh conditions.

The specific applications of MOA-3P in various industries and processes are detailed below.

Main Application Industries and Processes

Industry Field Specific Process/Scenario Functional Role Application Effect
Personal Care Shampoo, body wash, facial cleanser Mild anionic surfactant, thickening aid Provides fine foam and comfortable washing feeling, reduces formulation irritation, improves product consistency and stability
Skin cleansing system Primary or auxiliary surfactant Provides refreshing skin feel, excellent compatibility
Household and Industrial Cleaning Hard surface cleaners, multi-purpose cleaners Penetrant, emulsifier, degreasing component Effectively removes oil and dirt from hard substrates such as metal, glass, and ceramics, enhances detergency and improves rinsing performance
Industrial degreasing, kitchen cleaning Oil emulsifying dispersant Significantly reduces oil-water interfacial tension, forming stable and fine emulsion systems
Textile Printing and Dyeing Desizing, scouring, bleaching and other pretreatment processes Scouring agent, penetrant Accelerates penetration of working liquid, improves impurity removal efficiency
Fiber finishing process Antistatic agent Provides temporary antistatic property to fibers, facilitating subsequent processing
Compounding of printing and dyeing auxiliaries Wetting and penetrating component Improves uniformity of dye liquid wetting on fibers
Metalworking Fluids Cutting fluids, grinding fluids Emulsifier, lubricating component Stably disperses base oil in water, reduces friction and wear during machining
Rust preventive fluids, rolling fluids Rust preventive component, emulsifying dispersant Provides rust protection, reduces metal corrosion
Pesticide Formulations Emulsifiable concentrate (EC) Emulsifying dispersant Enables oil-phase pesticide active ingredient to form stable emulsion in aqueous medium, ensuring spontaneous emulsification during field dilution
Emulsion in water (EW) Emulsion stabilizer Promotes uniform dispersion of pesticide active ingredients, improves wetting and spreading properties of spray liquid
Emulsion Polymerization Acrylate, styrene-acrylic, etc. systems Anionic reactive emulsifier Participates in monomer emulsification and latex particle stabilization, improves particle size distribution of polymer emulsion, imparts excellent mechanical and chemical stability

Application Recommendations

In formulation design, it is recommended to use MOA-3P as a multifunctional component. In personal care products, it can serve as a mild primary surfactant or be compounded with betaine and amino acid surfactants; in industrial cleaning formulations, it can be combined with nonionic surfactants (such as AEO series) to leverage synergistic effects and enhance overall detergency; in metalworking fluids, it can function as both an emulsifier and a rust preventive; in emulsion polymerization, its use can improve the water resistance and adhesion of the final coating film.

Precautions

  • The product pH (1% aqueous solution, 25°C) is 1.5–3.0, which is an acidic system; neutralization adjustment is required during formulation.
  • It is recommended to wear impermeable gloves (such as butyl rubber or nitrile rubber) and chemical safety goggles during operation, avoiding direct contact with skin and eyes.
  • Although the product is a mild surfactant, it is still classified as skin irritant category 2 (H315) and serious eye irritant category 2 (H319). In case of contact, immediately rinse with plenty of water for at least 15 minutes.
  • Store in a cool, dry, and well-ventilated warehouse. Keep containers tightly sealed after use to prevent moisture absorption and contamination.
  • The specific dosage should be determined through experiments based on the target formulation system and process requirements, and it is recommended to start optimization at 1% to 10% of the total formulation weight.
