- In the Food Industry
It is used as a food additive, primarily as a humectant to retain moisture in food products. This helps prevent drying and maintains the texture and freshness of baked goods, cereals, and confectionery items. It also functions as a solvent for food - grade colors, flavors, and preservatives, ensuring their proper dispersion and stability in food formulations. Additionally, it can be found in some processed cheese products to improve their meltability and prevent the formation of a tough skin. - In the Chemical Industry
- It is used as a building block for the synthesis of various chemicals, such as polyester resins, polyurethanes, and plasticizers. These polymers are widely used in the manufacturing of plastics, foams, adhesives, and coatings, among other products.
- It can also be used as a reactant in chemical reactions to introduce hydroxyl groups into organic molecules, which can then be further modified to produce a variety of functionalized compounds for different application
- In the Industrial Sector
- It is used as an antifreeze and coolant in various industrial applications. Due to its low freezing point and high boiling point, it can effectively prevent the freezing and overheating of machinery and equipment in cold and hot environments, respectively. It is commonly used in automotive cooling systems, as well as in industrial processes that require temperature control.
- 1,2 - Propylene glycol is also used as a solvent and carrier in the paint and coatings industry. It helps to dissolve resins, pigments, and other additives, ensuring their proper mixing and application. It can improve the drying properties and film - forming characteristics of paints and coatings, resulting in a more durable and glossy finish.
- In the textile industry, it is used as a sizing agent and a softener. It helps to improve the strength and smoothness of fabrics during processing and gives them a softer hand feel after treatment.
- In the Tobacco Industry
- It is used in e - cigarettes and other tobacco - related products. In e - cigarettes, it serves as a base ingredient that, when heated, produces a vapor that carries the flavorings and nicotine (if present). It helps to create a smooth and consistent vaping experience. In traditional tobacco products, it can be used as a humectant to maintain the moisture content of the tobacco, preventing it from drying out and improving its burning characteristics.
- In the Cosmetics and Personal Care Industry
- In cosmetics, it is widely used as a moisturizer and emollient. It helps to improve the texture and feel of skincare products such as lotions, creams, and serums by preventing water loss and keeping the skin soft and supple.
- It is also used in hair care products like shampoos and conditioners to improve their viscosity and ensure even distribution of active ingredients. Additionally, it can be found in makeup products such as foundations and lipsticks to enhance their smoothness and prevent cracking.
- In the Pharmaceutical Industry
- 1,2 - Propylene glycol is a common ingredient in many pharmaceutical formulations. It is used as a solvent to dissolve drugs that are not readily soluble in water, facilitating their incorporation into liquid dosage forms such as oral solutions, syrups, and injectables.
- It serves as a humectant in topical medications like creams and ointments, helping to keep the skin hydrated and enhancing the drug's penetration through the skin. Moreover, it can act as a preservative in some pharmaceutical products, preventing the growth of microorganisms.
