Chemical Name: Propylene Glycol
Trade Names: KEMPG/Pharmaceutical grade
Introduction:
Propylene Glycol (KEMPG), known also by the systematic name propane-1,2-diol, is an organic compound (a diol alcohol) that is usually a tasteless, odorless and colorless clear oily liquid. It is hygroscopic and miscible with water, acetone and chloroform.
KEMPG is widely used as ingredient in a diverse range of cosmetics and personal care products. It provides outstanding functionality as a solvent, coupling agent, carrier, emulsion stabilizer, dispersant, softening agent, viscosity modifier and humectants. It is also used in oral care (mouth washers, toothpastes), skin care (creams, lotions and oils), deodorants and anti-perspirants (roll & stick), hair care (shampoo, conditioner and styler, coloring items), shaving (creams, foams, gels, after shaves), bath and shower soaps, gels and moisturizers, body care (wipers, antiseptics), cleaners and disinfectants.
MPG is an effective humectant, preservative and stabilizer, and may be used in such diverse applications as bakery goods, food flavorings, salad dressings and semi-moist pet food.
A main ingredient in many cosmetic products, KEMPG serves as a moisturizer, emulsifier, fragrance carrier and humectant, due to its ability to attract and hold water. Some of the daily-use products include:
KEMPG is also used as an enzyme stabilizer, diluent and solvent in leading liquid detergent formulations.
KEMPG has a variety of uses as it relates to food ingredients and food manufacturing including:
Typically in pharmaceutical applications, KEMPG is used as a non-active ingredient or carrier. KEMPG is used most frequently in oral, topical and injectable drug products.
