What are the functions and effects of propylene glycol

Propylene glycol is actually a chemical reagent. This reagent is very unfamiliar to many people. In fact, it has a wide range of uses. For example, it can appear in cosmetics. Women who love beauty cannot do without cosmetics. Because people nowadays have a strong awareness of health preservation, they generally do not use cosmetics that are ineffective or harmful to the skin. So what are the functions and effects of propylene glycol?

First, what are the functions and effects of propylene glycol? Moisturizer. The moisturizing mechanism is the same as glycerin, but it is not as sticky as glycerin. Antifreeze. Lowering the crystallization point of water makes the product less likely to freeze at sub-zero temperatures to avoid stability problems. Penetration enhancer. Propylene glycol is used as a penetration enhancer to enable the active ingredients in the product to be better absorbed through the skin. It is usually used in combination with oleic acid or azone and is widely used.

Second, propylene glycol is used as the raw material of resin, plasticizer, surfactant, emulsifier and demulsifier. Propylene glycol can also be used as antifreeze and heat carrier. Propylene glycol is an important raw material for unsaturated polyesters, epoxy resins and polyurethane resins, and the amount used in this regard accounts for about 45% of the total consumption of propylene glycol. This unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol is used as a carrier solvent; wetting agent; humectant; anti-caking agent; antioxidant; texturizing agent; surfactant; stabilizer; thickener; dough conditioner; emulsifier; flavoring agent; excipient; processing aid. GB2760~96 lists it as food processing aids.

What are the functions and effects of propylene glycol? Propylene glycol is mainly used as a solvent for various spices, pigments, preservatives, and an extraction solvent for vanilla beans, roasted coffee grains, natural spices, etc. Moisturizer and softener for candy, bread, packaged meat, cheese, etc. It can also be used as an anti-mold agent for noodles and fillings. Adding 0.006% to soy milk can keep the flavor unchanged when heated, and make white and shiny packaged tofu, which will expand in volume when fried. Propylene glycol is an intermediate for the fungicide difenoconazole. Propylene glycol can be used as a solvent to dissolve preservatives, pigments, antioxidants and other food additives that are difficult to dissolve in water, and then add them to food; it has strong hygroscopicity and has moisturizing and antifreeze effects on food. Our country stipulates that it can be used in pastries, with a maximum usage of 3.0g/kg.
