Mono Propylene Glycol USP/IND
SKU::RXSOL-19-1586-210
Propylene glycol is a humectant, which means that it is an ingredient that is added to cosmetics to increase Moisture Retention in skin and hair. Propylene glycol is well tolerated by the skin and shouldn't cause redness or irritation.
It is used to absorb extra water and maintain moisture in certain medicines, cosmetics, or food products. It is a solvent for food colors and flavors, and in the paint and plastics industries. Propylene glycol is also used to create artificial smoke or fog used in fire-fighting training and in theatrical productions.
According to the Material Safety Data Sheet on propylene glycol, the chemical is a strong skin irritant, and has been implicated in contact dermatitis.
Propylene glycol is tolerated well by the skin and shouldn't cause redness or irritation. Propylene glycol is a penetration-enhancing humectant.
Propylene Glycol USP is a widely used ingredient in pharmaceutical, food, cosmetic, personal care, flavors and animal feed applications; an overview of typical uses of Propylene Glycol USP as below.It must be emphasized that it is the user’s responsibility to consult area and country-specific regulations for details of approved use.
-
Pharmaceuticals - Solvent for active ingredients in oral, and topical products.
-
Cosmetics & Personal Care - Solvent, coupling agent, carrier, emulsion stabilizer, softening agent, viscosity modifier and humectant in many types of cosmetics and personal care products such as skincare, sun care, shampoo, bath/shower products, toothpastes, mouthwashes, shaving products and baby care products.
-
Flavors & Fragrances - Solvent and extraction solvent of flavors and fragrances for applications in food, beverages, perfumes and cosmetics.
-
Food - Various applications as a direct food additive (E 1520) such as a carrier or carrier solvent for colors, emulsifiers, antioxidants and enzymes (in Europe with maximum 1 g/kg in human foodstuffs), and humectant and stabilizer in fruits, vegetables and bakery goods (except in Europe). Propylene Glycol USP is also applied in indirect contact food applications, such as a low temperature heat-transfer fluid in the brewing, dairy and ice cream industries and for food storage facilities, an equipment cleaner fluid or a solvent for printing inks.
- Pet foods & Animal Feed - Humectant, emulsifier, preservative, solvent foradditives, energy source and aid for prevention of ketosis (acetonemia) in dairycattle. In EMEA a specific tailor made Propylene Glycol Animal Feed is offered forthis application.

Applications of Monopropylene Glycol (MPG)
Monopropylene Glycol (MPG) is a versatile chemical widely used across multiple industries due to its properties as a solvent, humectant, and antifreeze agent. Below is an overview of its key applications:
1. Food and Beverage Industry
- Food Additive: MPG is approved for use as a food additive and functions as a humectant, solvent, and preservative. It helps retain moisture in products such as baked goods, confectionery, and beverages.
- Flavor and Color Carrier: It acts as a carrier for flavors, extracts, and food colorings, ensuring uniform distribution and product stability, particularly in soft drinks and confectionery.
2. Pharmaceutical and Medical Industry
- Solvent in Medicines: MPG is commonly used to dissolve active pharmaceutical ingredients in syrups, oral solutions, and injectable formulations, ensuring effective drug delivery.
- Humectant in Topical Products: It is included in creams, ointments, and lotions to retain moisture and enhance product texture and performance.
- Low Toxicity: Due to its relatively low toxicity, MPG is suitable for both ingestible and topical medical applications.
