Monopropylene Glycol C3H8O2

Monopropylene Glycol C3H8O2

C3H8O2

Properties: Low volatility, miscible with water, alcohol, and ether, high purity clear colorless solvent. Especially suitable for cosmetic applications. Neutral and hygroscopic. Miscible with water in all proportions, less miscible with alcohols, esters, and ketones. Propylene glycol is a germicide approximately equal in strength to ethanol. Stops the proliferation of microorganisms in solutions. Generally the desired effect is obtained with concentrations in the range of 15-30%. Produced especially in high purity and odorless quality to meet the needs of the cosmetics industry.

General Applications: Has widespread use in flour product formulations. Used in flavor and essence industry, pharmaceuticals, and cosmetics. (Technical grade form is an important substance for polyurethane plastics and polyester resins. Also used in tobacco industry and lubrication of freezing machines in food industry.)

- Mouthwash (gargle), toothpastes, ointments, skin creams, shampoos, and perfumes (solutions containing propylene glycol generally remain clear even when heavily diluted with water)

- As a preservative in cosmetic products in emulsion formation,

- As a solvent for fragrances (essences),

- As an extractant to obtain active essences from natural essences,

- As a lubricant (e.g., for machines used in the cosmetics industry).

- Has softening properties on skin in cosmetics and detergent, used to reduce irritation on skin from surfactants. Used at 1-5% in gel, 0.5-5% in shampoo, 5-10% in creams, 5-10% in sunscreen milk.

Storage: Storage in stainless steel and aluminum containers is recommended. Contact with air should be avoided. This measure prevents any significant deterioration even during long-term storage. If not excluded from atmospheric oxygen, peroxides may form that can decompose into degraders, aldehydes, and acids.
