1. Household Chemicals & Personal Care
Utilize its mild, non-toxic, hydrophilic, and lubricating properties.
Cosmetics: Serve as moisturizers, emollients, solubilizers, and viscosity regulators. Have a refreshing, non-greasy texture that aids in the penetration of active ingredients.
Shampoo: Offers a silky skin feel, improves combability, and acts as a gentle surfactant component.
2. Industrial and Materials Science
Polymer Modification:
Prepare block copolymers: mPEG acts as the hydrophilic segment, copolymerizing with hydrophobic polymers (such as polylactic acid PLA, polycaprolactone PCL) to produce amphiphilic block copolymers, which are used in drug delivery, nanomicelles, etc.
Polyurethane materials: As a soft segment component, used in the preparation of hydrophilic, breathable polyurethane fibers, films, coatings, and adhesives.
Paints and inks:
Used as a wetting agent and dispersant, aiding in the dispersion of pigments.
Enhance the leveling and anti-adhesion properties of water-based coatings.
Metalworking Fluid: As a lubricant and coolant component, it reduces friction and heat accumulation.
3. Chemical Synthesis & Lab Research
Phase Transfer Catalyst: Facilitates transfer of reactants between aqueous and organic phases, promoting the reaction process.
Organic Synthesis Carrier: In solid-phase synthesis, water-soluble mPEG can serve as a recyclable polymer carrier, simplifying the purification process of the product.
Green Solvent: Low molecular weight mPEG is an excellent solvent for many organic compounds, with low vapor pressure, non-flammable, and biodegradable, making it an environmentally friendly reaction medium.
4. Other Fields
Agriculture: Used as a wetting agent, penetration agent, and controlled-release carrier for pesticides.
Textile: Used as antistatic agents, softeners, and finishers.
Papermaking: As a wetting agent and resin control agent.
