About Glycerol CAS 56-81-5

Glycerine, or glycerol is a simple polyol compound. It is a sweet, colorless, odorless, nontoxic and viscous liquid. It can absorb moisture from air and also can absorb hydrogen sulfide, sulfur dioxide and hydrogen cyanide. It is insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oil.

Application:

1 In coating industry, as raw material for manufacturing nitroglycerin, alkyd resin, epoxy resin;
2 In textile and dyeing industry, glycerol is use to produce lubricant, moisture absorbent, anti-shrinkage fabric treatment agent, dispersing agent and penetrating agent;
3 In medicine, glycerol is used to make various preparations, solvent, hygroscopic agent, antifreeze and sweeteners, compounding topical ointment and suppository;
4 In food, it is used as sweetener and in tobacco, glycerol is used as moisture absorbent and solvents;
5 Glycerol is also widely used in papermaking, cosmetics, leather industry, photograph, printing, rubber, etc.

Versatile Applications Across Industries

Glycerol fulfills multiple roles due to its excellent humectant, thickening, and solvent properties. It is widely utilized in pharmaceuticals, food processing, personal care formulations, and even in ink, lubricants, and antifreeze production. Its compatibility and safety profile make it a preferred ingredient for manufacturers worldwide.

This industrial-grade glycerol offers a minimum purity of 99.5%, ensuring reliable performance. Classified as non-hazardous under GHS, it's safe for handling and transport. The product remains stable under recommended conditions, making storage and usage straightforward for buyers and end-users.

Innovative Packaging and Export Solutions

Delivered in plastic drums, IBC tanks, or flexitanks, glycerol is packaged according to customer needs. This flexibility supports bulk transport and storage efficiency, making it ideal for large-scale operations across various sectors. Exported globally by experienced suppliers from China, product quality and logistical support are assured.

FAQ's of Glycerol CAS 56-81-5:

Q: How is glycerol (CAS 56-81-5) typically stored to maintain its stability and shelf life?

A: Glycerol is best kept in tightly closed containers, placed in cool, dry, and well-ventilated areas. Under these conditions, it remains stable and retains quality for up to 24 months.

Q: What are the main industrial uses of glycerol and how does it benefit different sectors?

A: Glycerol is valued as a humectant, solvent, sweetener, antifreeze, and plasticizer. Its versatility benefits pharmaceuticals, food, cosmetics, ink, lubricants, plastics, textiles, and personal care applications by enhancing product consistency, shelf life, and moisture retention.

Q: When should glycerol be selected over other solvents or humectants in manufacturing?

A: Glycerol is preferred when a non-toxic, odorless, and sweet-tasting ingredient is needed, especially for products where moisture retention, safety, and stability are primary concerns, such as in food and pharmaceuticals.

Q: Where is bulk glycerol manufactured and exported from, and what are the usual packaging options?

A: Bulk glycerol is widely manufactured and exported from China. It is packed in plastic drums, IBC tanks, flexitanks, or custom containers to suit client requirements for efficient transport and storage.

Q: What is the process for using glycerol in formulation or production?

A: Glycerol, being miscible with water and alcohol, is typically blended directly into formulations. It acts as a humectant, sweetener, or thickener depending on the specific application, providing uniform consistency and stability.

Q: How does the chemical structure of glycerol contribute to its physical and chemical properties?

A: Glycerol's structure (CH2OH-CHOH-CH2OH) offers three hydroxyl groups, resulting in strong hydrogen bonding, high viscosity, miscibility with water, and hygroscopicity, supporting its diverse industrial functions.

Q: What benefits does glycerol offer compared to alternatives in food, pharmaceutical, or cosmetic products?

A: Glycerol is non-toxic, odorless, and chemically stable, promoting safe consumption and reliable performance. Its ability to retain moisture and impart a sweet taste gives formulators enhanced product quality and consumer appeal.
