Cosmetic Grade 99% Propylene Glycol CAS 57-55-6
Do you know propylene glycol?
Propylene glycol, also known as 1,2-propylene glycol, is a colorless, odorless organic compound. It is a chemically stable liquid with low toxicity and good solubility. It is widely used as a wetting agent, solvent, and preservative in industry, food, medicine, and cosmetics. Its lubricating, moisturizing, penetrating, and solubility-enhancing properties make it widely used in the food, pharmaceutical, and cosmetic industries. In the food industry, propylene glycol is used to keep food moist and prevent freezing. In cosmetics, it helps maintain product stability and texture. In the pharmaceutical industry, propylene glycol is a key excipient.
Chemical Properties
Stability: Stable to heat and light, especially at low temperatures. It can be oxidized to propionaldehyde, lactic acid, pyruvic acid, and acetic acid at high temperatures.
Flammability: A flammable liquid that produces harmful gases such as carbon monoxide and carbon dioxide upon combustion.
Reactivity: It undergoes esterification with dibasic acids to form polyesters, nitric acid to form nitrate esters, and hydrochloric acid to form chlorohydrins. It can be converted to propionaldehyde upon heating to 170°C in dilute sulfuric acid.

Propylene glycol's Core Functions
Moisturizing Function
As a humectant, propylene glycol forms a protective film on the skin's surface, effectively absorbing and locking in moisture, reducing evaporation, maintaining the hydration of the skin or products, and preventing dryness.
Solubilizing Functions
As an excellent solvent and solubilizing agent, it can dissolve a variety of poorly soluble organic substances (such as drugs, fragrances, and pigments).
In combination with surfactants (when the critical micelle concentration is reached), it can significantly increase the solubility of insoluble substances, ensuring a uniform and stable texture in products such as pharmaceuticals, cosmetics, and oral solutions.
Penetration Enhancement
As a penetration enhancer, it increases the permeability of the skin's stratum corneum to active ingredients, accelerating the penetration and absorption of drugs or skincare active ingredients, thereby improving the efficacy or skincare results. It is widely used in transdermal drug delivery formulations and topical products.
Antioxidant Function
It has strong antioxidant properties, neutralizing free radicals and preventing oxidation reactions, thereby helping to repair skin cells and alleviate skin problems caused by oxidation.
Antibacterial and Antiseptic Function
It inhibits bacterial growth and can be added as an antibacterial preservative to cosmetics, pharmaceuticals, wet wipes, and other products to prevent microbial growth and extend product shelf life.
Antifreeze Function
As an antifreeze agent, it lowers the freezing point of water and is widely used in automotive antifreeze, paints, inks, and other applications, ensuring that these fluids do not freeze in low temperatures and maintain their normal function.
Plasticizer Function
As a plasticizer, it increases the flexibility and plasticity of plastics, improving their processing properties and making the final product less prone to cracking and brittleness.
Carrier and Stabilizing Functions
In flavors and fragrances, it acts as a carrier to help evenly disperse flavoring compounds.
In pharmaceuticals, it acts as a stabilizer, improving the stability of drug ingredients and preventing degradation.
Main Uses of Propylene Glycol
Cosmetics and Personal Care: Used as a humectant, solvent, and softener, widely used in skin care products, toothpaste, and fragrances.
Industrial: Used in the production of unsaturated polyester resins, as well as surfactants, plasticizers, antifreeze agents, and lubricants.
Food: Used as a solvent, humectant, stabilizer, and emulsifier in beverages, ice cream, and baked goods.
Pharmaceutical: Used as a solvent, preservative, and ointment base for injectables, oral medications, and topical medications.
Other Applications: Used as a tobacco humidifier, mildew inhibitor, fruit ripening preservative, and animal feed additive.
