Propylene glycol

Propylene glycol is used in a variety of products and manufacturing processes.

Uses

Pharmaceuticals – Propylene glycol can be used in different forms of drugs including oral drugs like capsules and tablets, topical drugs like creams and gels, and intravenous (injected) drugs.

Cosmetics- Propylene glycol is a commonly found ingredient in cosmetic, personal, and skin care products.

Some of these functions are:

• Humectant: Humectants are included in cosmetic and skin care products for their moisturizing abilities. Propylene glycol works as a humectant by attracting moisture to the skin, and consequently hydrating and moisturizing it.
• Solvent: Propylene glycol is used to dissolve substances in a product formulation to get them to mix and work together properly. It also acts as the carrier for active ingredients.
• Emollient: Emollients are ingredients that soothe and hydrate the skin. They’re very useful in skin care products for treating dry skin. Propylene glycol is used as an emollient because it forms an oily layer on the skin, and prevents water loss.
• Viscosity control: Propylene glycol is used to reduce the thickness of cosmetic formulations and products. This helps them spread across the skin better, and it also improves how well the products are absorbed.
• Preservative: Porpelyne glycol is often used in combination with other chemicals as a preservative in cosmetic and skin care products.

Food- Some of the ways propylene glycol is used in food include:

• As an anticaking agent, helping to prevent lumps from forming in food
• As a solvent in food flavorings, helping to dissolve and mix ingredients in them.
• As a dough strengthener
• To improve flavors in food
• As a preservative, its antimicrobial properties help to kill and/or prevent the growth of microorganisms like bacteria and mold
• A s a food thickener
• To help retain moisture in food

Antifreeze- Propylene glycol drops the freezing point of water and water-based liquids, making it effective as an antifreeze.

Electronic Cigarettes- Alongside vegetable glycerin, propylene glycol is the major ingredient in the liquids (e-liquids). It also functions as a carrier for nicotine and flavorings which are added to some e-liquids.
