Product Description

Product Introduction

Glycerol, also known as glycerin or propanetriol, is a colorless, odorless, and viscous liquid with a sweet taste. It is a polyol compound that contains three hydroxyl (-OH) groups in its molecular structure.

Naturally, it can be found in animal fats and vegetable oils as part of triglyceride molecules. Commercially, it is mainly produced through the hydrolysis of fats and oils, where triglycerides are broken down into glycerol and fatty acids. Another common production method is the fermentation of sugars, although the fat - hydrolysis route is more prevalent for large - scale industrial production.

Glycerol has strong hygroscopicity, meaning it can absorb moisture from the air, which makes it useful in many applications where moisture retention is needed. It is also miscible with water and many organic solvents, expanding its range of use in various formulations.

Product Application

1 Food Industry

• Sweetener and Moisturizer: In the food industry, glycerol serves as a sweetener, providing a mild sweetness. More importantly, it acts as a moisturizer or humectant. In baked goods like cakes and bread, it helps retain moisture, keeping the products soft and fresh for a longer time. For example, in fruit - filled pastries, glycerol can prevent the fruit filling from drying out and the pastry crust from becoming too hard.
• Food Additive for Stability: It is used as an additive to improve the texture and stability of food products. In processed meats, it can help maintain the juiciness and prevent fat separation. In confectionery, such as chocolates and candies, it contributes to a smooth texture and can prevent sugar crystallization, ensuring the products have a consistent quality.

2 Pharmaceutical Industry

• Excipient in Medications: Glycerol is a common excipient in pharmaceutical formulations. In oral medications like syrups, it acts as a solvent and a sweetening agent, making the medication more palatable, especially for children. In topical medications, such as creams and ointments, it functions as a moisturizer. For instance, in skin creams for treating dry skin conditions, glycerol helps hydrate the skin by attracting and retaining moisture, enhancing the cream's therapeutic effect.
• Stabilizer in Injections: In some injectable medications, glycerol is used as a stabilizer and a tonicity adjuster. It helps maintain the stability of the drug components and ensures the proper osmotic pressure of the injection solution, which is crucial for the safety and efficacy of the injection.

3 Cosmetics and Personal Care

• Moisturizing Agent in Skin Care: In cosmetics, glycerol is a key ingredient in most skin care products, including lotions, moisturizers, and facial cleansers. Its hygroscopic nature allows it to draw moisture from the environment and lock it into the skin, keeping the skin hydrated, soft, and supple. It is particularly beneficial for dry and sensitive skin types, as it helps restore the skin's natural moisture barrier.
• Conditioning Agent in Hair Care: In hair care products like shampoos and conditioners, glycerol acts as a conditioning agent. It helps smooth the hair cuticles, reducing frizz and making the hair more manageable. It also adds shine to the hair, giving it a healthy appearance. For example, in leave - in conditioners, glycerol provides long - lasting moisture to the hair, protecting it from damage caused by environmental factors like dry air.

4 Industrial Applications

• Plasticizer in Polymers: Glycerol is used as a plasticizer in the production of polymers. It can improve the flexibility and workability of materials like plastics and rubbers. In the manufacturing of biodegradable plastics, glycerol can be added to modify the mechanical properties, making the plastics more suitable for various applications, such as packaging materials.
• Component in Antifreeze and Coolants: In some industrial antifreeze and coolant formulations, glycerol is used as an alternative to ethylene glycol. It has a lower toxicity compared to ethylene glycol, making it a safer option in certain applications. Glycerol - based coolants can effectively lower the freezing point and raise the boiling point of the coolant, providing protection to industrial equipment in extreme temperature conditions.
• Raw Material for Chemical Synthesis: It serves as a raw material for the synthesis of various chemicals. For example, it can be used to produce glycerol carbonate, which is used in the production of solvents, adhesives, and coatings. Glycerol can also be converted into other polyol compounds or used in the synthesis of surfactants, expanding its role in the chemical industry.
