Product Details

DHK114 is an anionic/nonionic scouring agent, it has emulsifying, wetting and dispersing property. After treatment, cotton has excellent water absorption property and whiteness. It is suitable for cold pad batch, scouring process for cotton, flax, etc.

Key Features and Typical Benefits

◆ Excellent wetting property under conditions of high temperature and high alkali value. Has best wetting property at 60℃ to ensure liquid pick-up and improve scouring effect.

◆ Excellent wetting, emulsifying, dispersing property, especially emulsifying property.

◆ Excellent water absorption property and whiteness.

◆ High alkali resistance: room temperature NaOH 220g/L.

◆ Scouring and wetting property two in one to ensure excellent scouring agent.
