Propylene Glycol 99%, often referred to simply as "PG 99%," is a colorless, odorless, and nearly tasteless organic compound. It is a type of glycol that is widely used in various industries for its versatile properties. Here's a brief description:

Propylene Glycol 99% is a synthetic organic compound with the chemical formula C3H8O2. It is a clear and viscous liquid at room temperature. This compound is hygroscopic, meaning it can absorb and retain moisture from the environment. Propylene Glycol 99% is produced through the hydration of propylene oxide and is known for its exceptional solubility in water.

Key Characteristics and Functions

1. Humectant: Propylene Glycol 99% is commonly used in the cosmetics and personal care industry as a humectant. It helps retain moisture in various products, including skincare lotions, shampoos, and hair conditioners, keeping the skin and hair hydrated.

2. Solvent: It serves as an effective solvent for a wide range of substances, making it valuable in the formulation of pharmaceuticals, food products, and flavors. It can dissolve both water-soluble and oil-soluble ingredients.

3. Antifreeze: Propylene Glycol 99% is used in the automotive industry as an antifreeze agent, helping to lower the freezing point of water and prevent engine coolant from freezing in cold temperatures.

4. Food Additive: It is considered safe for use in food and beverages, where it functions as a carrier for flavors and colors, as well as a food preservative.

5. Pharmaceuticals: In the pharmaceutical industry, it is used as a solvent in oral and injectable medications and as a carrier for active pharmaceutical ingredients.
