One , The role and dosage of propylene glycol in cosmetics
. First, what are the roles and effects of propylene glycol? Moisturizer. The moisturizing mechanism is the same as that of 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.
Second, propylene glycol is used as a raw material for resins, plasticizers, surfactants, emulsifiers and demulsifiers. Propylene glycol can also be used as antifreeze and heat treatment agents. carrier. Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. Its consumption 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; texture improver; surfactant; stabilizer; thickener ;Dough conditioner; emulsifier; flavoring agent; excipient; processing aid. GB2760~96 is listed 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, vanilla beans, roasted coffee grains, and natural spices extraction solvents.
Moisturizing and softening agent for candies, bread, packaged meats, cheese, etc. It can also be used as an anti-mold additive for noodles and stuffing cores.
Adding 0.006% to soy milk can keep the flavor unchanged when heated and produce white and shiny packaging.Tofu expands in size when fried.
Propylene glycol is an intermediate of the fungicide difenoconazole. Propylene glycol is 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 anti-freezing effects on food. Our country stipulates that it can be used in pastries, and the maximum usage amount is 3.0g/kg.
2. Is propylene glycol a soap base?
1. Soap base The soap manufacturer adds salt during the soap making process to separate the glycerin, lye, water and soap base to form a 100% soap base, and then uses a machine to press the soap base into a beautiful shape. Sell again. Although this kind of soap can be used immediately, it lacks the glycerin in cold process soap, so it will feel a little tight after washing.
2. Propylene glycol is mainly used as a moisturizer, solvent, and solubilizer in skin care products.
3. Propylene glycol is used as a solvent and softener in cosmetics in skin care products. Propylene glycol is added to skin care products and is generally used in lotions and essences. Since it is a polyol, it is a small molecule moisturizing ingredient that can lock in moisture and play a moisturizing role. However, its water absorption is relatively weak and its moisturizing effect is average. ; In addition, in skin care products, in addition to its moisturizing effect, it also has the effect of promoting skin absorption. It can be used as a penetrant to allow the ingredients of skin care products to be better absorbed by the skin.
3. What is dipropylene glycol
Dipropylene glycol is a It is a substance that has a very good restorative effect on the skin, so it is very common in cosmetics. Dipropylene glycol is a transparent, colorless, viscous and hygroscopic linear fatty alcohol liquid, commonly used in ointments, facial masks, lotions, facial cleansers, essences, makeup removers, moisturizing lotions and plant extracts, etc. , you can see this ingredient. It is generally a hydrophilic and moisturizing ingredient commonly found in makeup removers. Its real function is to help dissolve dirt and prevent the skin from drying out too quickly during makeup removal.
4. Can propylene glycol be used on the face
No. Propylene glycol is a colorless, viscous and hygroscopic substance. It is a common hydrophilic moisturizing ingredient in makeup remover. Its real function is to help dissolve dirt and prevent the skin from drying out too quickly during makeup removal. It is also often used in lotions and essences. In addition to its moisturizing ability, it can help the active ingredients penetrate into the skin.It is transparent and has antiseptic properties, but it is irritating to the skin and eyes.
This ends the content about the efficacy and role of propylene glycol. I hope it will be helpful to everyone.
