Features
Directly Compatible with Neutral Systems
With a pH of 7.05 (range 6.3–7.3), it falls within the neutral range and can be used directly in conventional aqueous systems without altering existing acidity or alkalinity.
High Polymer Chain Supported Structure
With a molecular weight ≥2,000,000 Da, the long-chain molecules form an entangled structure in water, transforming the system from a low-viscosity state to a continuous structure.
Easy to Disperse and Dispose of
Appears as a white to off-white powder or granules, with a drying loss of 4.67%, allowing for direct weighing and dispersion under normal conditions.
Applications
Food Industry: Used in beverages, gels, and compound foods to increase system viscosity and enhance water-holding capacity, affecting product taste and texture.
Daily Chemical Industry: Used in skincare and cleansing products as a water-retaining and viscosity-regulating component, affecting product spreadability and user experience.
Functional Materials: Used in aqueous systems to achieve water retention and viscosity regulation through polymer chain interactions, for the control of basic system properties.
