In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye , usually must be larger than one micrometer , and will eventually settle , although the mixture is only classified as a suspension when and while the particles have ...
A dispersant or a dispersing agent is a substance, typically a surfactant, that is added to a suspension of solid or liquid particles in a liquid (such as a colloid or emulsion) to improve the separation of the particles and to prevent their settling or clumping.
Hypromellose is a solid, and is a slightly off-white to beige powder in appearance and may be formed into granules. The compound forms colloids when dissolved in water. . This non-toxic ingredient is combustible and can react vigorously with oxidizing ag
In polymer chemistry, suspension polymerization is a heterogeneous radical polymerization process that uses mechanical agitation to mix a monomer or mixture of monomers in a liquid phase, such as water, while the monomers polymerize, forming spheres of polymer. [2]
It is also used in the makeup and toothpaste industries to control the products' texture. Due to its ability to retain moisture, it is also used in skincare products. CMC serves as a film-forming agent in approximately 10% of sunscreens. CMC aids in pigment suspension and dispersion, binding other ingredients for even distribution.
This separation is achieved by addition of a flocculating or coagulating agent, which induce the aggregation of the suspended solids. The aggregates are normally separated by sedimentation, leading to sewage sludge. Commonly used flocculating agents in water treatment include multivalent metal ions (e.g., Fe 3+ or Al 3+), polyelectrolytes, or both.
In an executive order, Trump suspended the entry of all undocumented migrants to the US, and border patrol agents have been instructed to turn people away without granting them asylum hearings.
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces , soups , and puddings without altering their taste; thickeners are also used in paints , inks , explosives , and cosmetics .
