HPMA is a low-phosphorus, environmentally friendly water-soluble polymer widely used in water treatment and industrial processes. However, it also finds niche applications in daily chemical products due to its scale inhibition, dispersion, and chelation properties. Below are its key uses in household and personal care products:
1. Detergents & Cleaning Products
(1) Laundry Detergents & Dishwashing Liquids
Anti-scaling Agent: Prevents calcium/magnesium deposits (e.g., on fabrics, glassware, and dishwasher interiors).
Dispersant: Helps suspend dirt and prevents redeposition on fabrics.
Synergist for Builders: Enhances the performance of zeolites and citrates in phosphate-free detergents.
(2) Hard Surface Cleaners (Bathroom, Kitchen)
Prevents limescale buildup on tiles, faucets, and showerheads.
Improves foam stability in acidic/alkaline cleaners.
2. Personal Care & Cosmetics
(1) Shampoos & Body Washes
Chelating Agent: Binds metal ions (Ca²⁺, Mg²⁺) in hard water, improving lathering and cleansing efficiency.
Prevents Soap Scum: Reduces residue formation when combined with surfactants.
(2) Skin Care & Creams
Stabilizer: Helps maintain emulsion stability in lotions.
Mild Exfoliant: Used in low concentrations for gentle skin exfoliation (similar to PHA derivatives).
(3) Oral Care (Mouthwash, Toothpaste)
Anti-tartar Agent: Inhibits calcium phosphate deposition (dental calculus).
Compatibility: Works with fluoride and other active ingredients.
3. Household Water Treatment
Descaling Agents: Used in kettle, coffee machine, and humidifier cleaners to dissolve limescale.
Water Softener Additive: Enhances ion-exchange resin efficiency in home water softeners.
4. Advantages Over Traditional Chemicals
