Pharmaceutical-grade talc is a mineral primarily composed of magnesium, silicon, and oxygen. It is widely used in the pharmaceutical industry due to its unique properties. Here are some key details:

Purity: Pharmaceutical-grade talc is highly purified and meets stringent regulatory standards, making it safe for use in medicinal products.

Uses:

1. Excipient: It serves as an excipient in tablet formulations, providing bulk and improving flow properties.
2. Lubricant: Talc is often used as a lubricant in the manufacturing of tablets and capsules.
3. Anti-caking agent: It helps prevent clumping in powdered formulations.

Properties:

1. Inertness: Talc is chemically inert, meaning it doesn’t react with active pharmaceutical ingredients.
2. Moisture control: It has moisture-absorbing properties, which help stabilize formulations.

Regulatory Status: Talc used in pharmaceuticals is subject to strict regulations from authorities such as the FDA to ensure its safety and efficacy.

Manufacturing: Pharmaceutical-grade talc is processed to remove impurities, including asbestos, which can pose health risks.
