hydroxypropyl methy cellulose used in Detergent grade
Detergent grade HPMC hydroxypropyl methyl cellulose is a powder with a white or slightly yellow hue, possessing no odor or taste, and is non-toxic. It exhibits rapid dispersion in a mixture of cold water and organic matter, achieving maximum consistency within a few minutes, resulting in a transparent viscous solution. This solution has surface activity, high transparency, strong stability, and is unaffected by pH during water dissolution. It serves as a thickening and antifreeze agent in shampoos and shower gels, offering water retention and excellent film-forming properties for both hair and skin. With the increase in basic raw material costs, cellulose, known for its antifreeze thickening capabilities, can be employed in laundry detergents, shampoos, and shower gels to reduce costs while achieving desired outcomes.
Characteristics and advantages of washing grade cold water soluble cellulose HPMC:
Low irritation and high-temperature resistance.
Wide pH stability, ensuring stability in the range of pH 3-11.
Enhances rationality and cost-effectiveness.
Increases and stabilizes bubbles, improving skin sensation.
Effectively improves system liquidity.
Easy to use, quickly dispersing in cold water without clumping.
Application scope of detergent grade HPMC:
Instant soluble HPMC finds applications in laundry detergents, shampoos, body washes, facial cleansers, lotions, creams, gels, toners, hair conditioners, shaping products, toothpaste, mouthwash, and toy bubble water.
Points to note:
Unqualified detergent grade HPMC may exhibit poor transparency and thickening effects, leading to dilution over time, and some may even develop mildew. To prevent cellulose precipitation during use, it is advisable to stir before achieving consistency.
Difference between slow-solution and instant-solution HPMC products:
HPMC can be categorized into instant and slow solution types. Instant HPMC undergoes surface treatment with a crosslinking agent during production, allowing it to disperse quickly in cold water without immediate dissolution. In contrast, slow-soluble HPMC is mainly used in mortar, putty, and dry mixing mortar applications, requiring uniform dry mixing before adding water for viscosity. Quick-soluble instant HPMC has a broader range of applications, especially in gray calcium-based putty, cement-based mortar, glue, and coating, exhibiting quick viscosity calibration in alkaline conditions. Slow-soluble HPMC, on the other hand, dissolves slowly in cold water and requires hot water or sufficient agitation for dissolution. Both types share similar physicochemical indexes but differ in application range and speed of dissolution.
