Propylene Glycol (MPG)

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.

Product Name:

  • Propylene Glycol
  • MPG
  • Mono Propylene Glycol
  • KEMPG

General Applications

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.

Cosmetic & Personal Care

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:

  • Baby wipes
  • Bubble baths and shower products
  • Deodorants and antiperspirants
  • Shampoos, styling gels and hair dyes
  • Shaving products
  • Face creams
  • Hand sanitizers, antibacterial lotions, and saline solutions
  • Dental care (mouth washes and toothpastes)
  • Perfumes and colognes
  • Color cosmetics (blushes, eyeliner, lipsticks, eye shadow)

KEMPG is also used as an enzyme stabilizer, diluent and solvent in leading liquid detergent formulations.

Food Ingredients

KEMPG has a variety of uses as it relates to food ingredients and food manufacturing including:

  • Solvent for food additives (i.e., colors, antioxidants, enzymes and emulsifiers)
  • Flavor agent
  • Humectant and stabilizer in items such as fruits, vegetables and bakery goods
  • Low-temperature heat-transfer fluids involving indirect food contact, such as brewing and dairy uses, as well as refrigerated grocery display cases
  • Plasticizer and softening agent for items such as cork seals
  • Solvent for printing inks used in food packaging
  • Equipment cleaner, to remove contamination from food processing equipment

Pharmaceutical

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.
