Physical and Chemical Properties

1.Appearance: white or off-white powder

2.Particle size: about 95% through 100mesh ; 100% through 80mes.Special particle size is about 40 ~ 60 mesh;

3.Carbonation temperature: 280-300°C

4.Bulk density: 320-350kg/m 3 (generally about 0.5g/cm3 ) , specific gravity is 1.26-1.31

5.Temperature to change color: 190-200°C ;

6.Surface tension: 42-56dyn/cm,2% solution.

7.Dissolution properties: dissolve in water and some solvent. Such as, the suitable proportion of ethanol/ water, propanol/water. Its aqueous solution provides surface activity and high transparence and stable properties. Various products have different gel temperatures. Solubility changes with viscosity. Lower the viscosity is, higher the solubility is. Different types of HPMC have different properties. Its dissolution is not subject to PH.

8.With the reduction of methoxyl content, gel point rises, solubility in water and surface activity decrease.

9.HPMC has the ability of thickening, anti-salt, water retention, good film-forming, anti-enzyme, dispersing, bonding, and low ash content.

With the development of the Cellulose ether requirements, the detergents field (includes cosmetics, shampoo, hand sanitizer, laundry liquid and other personal care products) have become a part of daily necessity.

Sinokem SD200000S is an essential additives in the detergents application to achieve some key properties like thickening, water retention and film-forming properties.

Product Description:

SD200000S is free flowing surface treated powder, which is designed for detergents application use. The function is thickening agent and rheology modification.
