Why Aerosil is used in tablet?

1.1 Effect of coating agent. … Aerosil® R972’s stabilizing effect compared to Aerosil® 200 was assumed to be associated with its hydrophobic surface property, which might have resulted in reduced moisture uptake. Thus, Aerosil® R972 was selected to be the coating agent for manufacturing prototype tablet formulations.

Colloidal silicon dioxide (trade name AEROSIL) is widely used as a glidant in the manufacture of powders, capsules, and tablets [8, 9] . … The flow-enhancing effect of a new compacted, hydrophilic colloidal silicon dioxide on microcrystalline cellulose and pregelatinized starch was studied in the work of Jonat et al.

Can you eat fumed silica?

* Do not eat, smoke, or drink where Silica, Amorphous (Fume) may be present since the chemical can be swallowed. Wash hands carefully before eating, drinking, smoking, or using the toilet.

Is magnesium stearate flammable?

Under Fire Conditions: Not flammable. In common with many organic chemicals in powder form, this product may be capable of forming flammable dust clouds in air. Hazardous Polymerization: Will not occur. Conditions to Avoid: High temperatures, sparks, open flames and all other sources of ignition.

Is silica a silicon dioxide?

Silicon dioxide (SiO₂), also known as silica, is a natural compound made of two of the earth’s most abundant materials: silicon (Si) and oxygen (O₂). … When you sit on a beach, it’s silicon dioxide in the form of sand that gets between your toes. It’s even found naturally in the tissues of the human body.

How is Aerosil made?

Fumed silica is made by hydrolysis of chlorosilanes in an oxygen–hydrogen gas flame, according to a process developed by Degussa more than 60 years ago (Aerosil^® Process). The product is a highly dispersed silicon dioxide. With the process conditions, the partiele size can be controlled.

Is silica harmful to humans?

Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen.

What is the side effect of silicon dioxide?

Long term inhalation of silica dust may lead to issues in the lungs, including: silicosis, a progressive, irreversible lung disease. lung cancer. chronic obstructive pulmonary disease, or COPD.

What is CAB O SIL?

CAB-O-SIL M-5 is a medium surface fumed. silica which imparts significant increase in. viscosity in liquid systems, free flow of powders. and reinforcement of silicone and organic. rubbers.

Is fumed silica hydrophilic?

The hydrophilic nature of fumed silica is a result of the attachment of hydroxyl groups onto silica atoms just at the surface of the particle; the product is now capable of hydrogen bonding—this makes it dispersible in water.

Which coating increases the weight of tablet significantly?

3.5. 1 Sugar coating. Unlike film coating, sugar coating is a more laborious multistep process, leading to final tablet weight increases of up to 30%–50%, significantly increasing tablet size. The process of sugar coating involves various steps, i.e., sealing, subcoating, smoothing, coloring, and polishing.

What excipient means?

An excipient is a substance formulated alongside the active ingredient of a medication, included for the purpose of long-term stabilization, bulking up solid formulations that contain potent active ingredients in small amounts (thus often referred to as bulking agents, fillers, or diluents), or to confer a …

What is widely used in chewable tablets?

The oral processing of chewable tablets makes taste-masking a necessity for most formulations. Sweeteners are almost always used and represent the simplest means by which to address taste concerns. Combinations of bulk sweeteners (e.g., sugars or polyols) with high-intensity sweeteners (e.g., aspartame) are common.

Why is magnesium stearate used in tablets?

Magnesium stearate is an additive that is most frequently used as a lubricant. Magnesium stearate is capable of forming films on other tablet excipients during prolonged mixing, leading to a prolonged drug liberation time, a decrease in hardness, and an increase in disintegration time.

What is Glidant in pharmaceuticals?
