Sourcing High-Purity Glycerin (56-81-5): A Buyer's Guide
For any procurement specialist or product formulator, sourcing the right chemical ingredients is a critical task. Glycerin, identified by its CAS number 56-81-5, is one such versatile compound that demands careful consideration regarding its source and purity. As a leading supplier of Glycerin, we understand the nuances involved in its selection and are here to guide you through the process. This article aims to equip you with the knowledge to confidently buy Glycerin, focusing on purity, applications, and reliable sourcing from manufacturers.
Glycerin, also known as glycerol, is a trihydroxy alcohol that presents as a colorless, odorless, viscous liquid with a sweet taste. Its hygroscopic nature, stemming from its three hydroxyl groups, makes it an excellent humectant and emollient. The quality and grade of Glycerin can vary significantly, impacting its suitability for different applications. Understanding these distinctions is the first step in making an informed purchase decision.
Understanding Glycerin Purity and Grades
Glycerin is available in various grades, primarily distinguished by its purity level and intended application. Key grades include:
- Food Grade Glycerin: This grade meets strict standards for purity (typically ≥99.5%) and is safe for consumption. It is widely used in the food and beverage industry as a sweetener, humectant, and solvent. When you need edible glycerol, this is the grade to look for.
- Pharmaceutical Grade Glycerin: Similar to food grade in purity, this Glycerin adheres to pharmacopoeia standards (like USP, EP, BP) and is used in medicines, cough syrups, and as a skincare ingredient. It's essential for its excipient properties and safety in medical formulations.
- Technical Grade Glycerin: While still a functional product, technical grade Glycerin may have lower purity levels and is suitable for industrial applications such as antifreeze, resins, and as a chemical intermediate.
As a manufacturer, we specialize in supplying high-purity Food Grade and Pharmaceutical Grade Glycerin, ensuring our clients receive the quality they demand.
Key Applications Driving Demand for Glycerin
The widespread utility of Glycerin is a major factor in its consistent demand:
- Food & Beverage: Sweetener, humectant, solvent for flavors/colors, bulking agent.
- Pharmaceuticals: Excipient in syrups, suppositories, topical treatments, eye drops.
- Cosmetics & Personal Care: Moisturizer, emollient in lotions, creams, soaps, toothpaste.
- Industrial: Antifreeze, plasticizers, resins, lubricants, chemical intermediate.
For businesses in these sectors, securing a consistent supply of Glycerin is vital. If you are looking to buy Glycerin for any of these applications, understanding the specifications is crucial.
Finding a Reliable Glycerin Manufacturer and Supplier
When sourcing Glycerin, especially in bulk, partnering with a reputable manufacturer is key to ensuring consistent quality, competitive pricing, and reliable delivery. Look for suppliers who can provide:
- Certifications: Proof of adherence to food, pharmaceutical, or industrial standards.
