HEDP-Na4 (tetrasodium hydroxyethylidene diphosphonate) is mainly used in cleaning agents in the following aspects:

  1. Metal surface cleaning

HEDP-Na4 is able to form stable complexes with many metal ions, such as iron, copper, zinc, and so on, so as to effectively remove oxidization, rust, and mineral deposition on metal surfaces. This characteristic makes it excellent in metal surface cleaners, especially suitable for cleaning boilers, pipelines and other metal equipment.

  1. Industrial cleaners

    In industrial cleaners, HEDP-Na4 is commonly used to remove scale and mineral deposits. Its chelating ability prevents metal ions such as calcium and magnesium from combining with anions in water to form scale, and also dissolves already formed scale. In boiler cleaning agent, the concentration of HEDP-Na4 is usually 1000-2000mg/L.

    1. Cleaning application in light textile industry

    In light textile industry, HEDP-Na4 can be used as a metal and non-metal cleaning agent for removing impurities and metal ions on the surface of fibers to improve the cleanliness and softness of fabrics.

  2. Application in daily chemicals

    HEDP-Na4 can also be used as a component of household detergents to improve the cleaning effect and prevent the redeposition of limescale and stains. In addition, in cosmetics and personal care products, HEDP-Na4 acts as a chelating agent to prevent metal ions from interfering with product stability.

  3. Other cleaning-related applications

    Printing and dyeing industry: as a peroxide stabilizer and color-fixing agent, preventing color changes caused by the combination of dyes and metal ions, and improving dyeing uniformity and color stability.

    Paper industry: as bleaching auxiliary and retention aid, to prevent metal ions from interfering with bleaching agent and improve the quality and strength of paper.

Summarize

HEDP-Na4 is widely used in cleaning agents, mainly due to its excellent chelating ability and corrosion inhibition performance. It can effectively remove oxides and mineral deposits on metal surfaces while preventing scale formation and redeposition, and is widely used in many fields such as industry, light textiles, and daily-use chemicals.
