  HPMC

  Posted by Tyss on October 13, 2025 at 3:19 am

  Dear all,

  I am currently using Mecellose FMC 8821 powder(manufacturer: Samsung) at a dosage of 0.5% of the total product weight in our detergent formula “soap paste laundry”.

  At this concentration, we have observed that the product becomes non-homogeneous after a few days, both at 45°C and at room temperature.

  The internal product specifications are as follows:

  Minimum viscosity: 2500 cP

  pH range: 7-8

  Is there anyone in this forum familiar with this material who could guide me on how to resolve this issue?

  The formula composition is as follows:

  Aqua: qsp100%

  Soap 100%HO: 5%

  LABSA: 6%

  Preservative: 0.1%

  EDTA 4Na: 0.06%

  Fragrance: 0.75%

  Opacifier: 0.3%

  Salt: max 1.5%

  Mecellose powder: 0.5%

  I look forward to your feedback and thank you in advance for you assistance.

  I’m not familiar with the soap-paste making process, but it might just be that you’re using the wrong HPMC.

  According with most of the internet info, it’s made for industrial use (cement and such)- photo attached
