Powder hand written notes pdf

Powder is a fine, dry substance consisting of individual particles or grains. It can be made from various materials such as minerals, chemicals, or plants, and is commonly used in a wide range of applications, including:

1. Cosmetics: Powder is commonly used in cosmetics such as face powder, blush, eyeshadow, and lipstick.

2. Medicines: Powder is commonly used in medicines, such as aspirin and antibiotics, as a way to deliver the active ingredient.

3. Food: Powder is commonly used in the food industry, such as in baking powder, spices, and powdered drinks.

4. Cleaning: Powder is commonly used in cleaning products, such as laundry detergent and dishwashing detergent.

Powder can be made in different ways, such as through grinding, crushing or milling, and can have different particle sizes, shapes, and densities. The properties of powder depend on the material it is made from, its particle size and shape, and the method used to create it. For instance, fine powders are more likely to be airborne, while larger, denser powders may settle more quickly.

Powder can pose health risks if inhaled, particularly if it is fine and airborne. Care should be taken when handling powders, such as using protective equipment, working in well-ventilated areas, and avoiding inhalation. Proper storage of powders is also important to prevent spills, contamination, or fire hazards.
