Viscosity standard for hydroxypropyl methylcellulose (HPMC) added to laundry detergent

The viscosity standard of hydroxypropyl methylcellulose (HPMC) added to laundry detergent can vary according to specific product formulations and application requirements. Generally, the viscosity range of HPMC used in laundry detergent is generally between 2,000 and 100,000 milliPascal seconds (mPa·s).

Different viscosity grades are suitable for different application scenarios and product types. The lower viscosity HPMC is suitable for use as a dispersant and thickener in laundry detergent, providing moderate viscosity and fluidity to improve washing effect and product stability. Higher viscosity HPMC can be used as a long-lasting and stable gelling agent to help maintain the viscosity and adhesion of laundry detergent.

It should be noted that the specific viscosity standard may vary according to different countries/regions, production standards and brands. Therefore, when using HPMC as a laundry detergent additive, it is best to select and use it according to product formulation requirements and relevant standards.
