Propyleneglycol Alginate, commonly known as PGA, identified by its CAS number 9005-37-2, stands as a highly versatile and essential raw material powder utilized across a spectrum of industries. Derived from natural sources, specifically brown algae, this polymer is modified through esterification with propylene glycol. This process enhances its stability in acidic environments compared to other alginates, making it uniquely valuable in formulations where pH is a critical factor.

The inherent properties of Propyleneglycol Alginate make it a sought-after ingredient. Its primary functions revolve around its ability to act as an effective thickening agent, a reliable stabilizer, and a potent emulsifier. These functional attributes are crucial for achieving desired texture, consistency, and stability in a wide range of end products. The material is typically supplied as a fine, cream-colored powder, ensuring ease of handling and incorporation into various processes.

Quality and purity are paramount when sourcing Propyleneglycol Alginate for sensitive applications. A high purity degree, typically exceeding 99%, is essential to ensure safety, efficacy, and consistency in final products. Key specifications often scrutinized include viscosity, which dictates its thickening power; moisture content, critical for storage stability; and the levels of water-insoluble substances, indicating proper processing and minimal impurities. Furthermore, strict limits on heavy metals such as Arsenic (As) and Lead (Pb) are non-negotiable for materials destined for ingestion or pharmaceutical use. Microbial testing for total plate count, fungi, yeasts, E.Coli, and Salmonella species is also standard practice to guarantee compliance with health and safety regulations.

The applications of Propyleneglycol Alginate are extensive and impactful. In the pharmaceutical industry, PGA is employed in oral suspensions and emulsions to prevent sedimentation and separation, ensuring uniform dosing. It can also function as a binder in tablets or a disintegrant, depending on the formulation. Its stabilizing properties are valuable in medicinal syrups and topical preparations. The food industry is another major consumer of PGA, where it is used in dressings, sauces, ice cream, yogurt, and baked goods as a stabilizer and thickener, preventing ice crystal formation in frozen desserts and maintaining emulsion stability in sauces. Its ability to perform well in acidic foods like salad dressings is a significant advantage. Beyond pharma and food, PGA finds use in the chemical sector as a rheology modifier and suspending agent in various formulations.

Ensuring the quality and safety of Propyleneglycol Alginate necessitates adherence to stringent manufacturing standards and certifications. Reputable suppliers provide material produced under conditions compliant with international standards such as ISO 9001, and for pharmaceutical applications, Good Manufacturing Practices (GMP) is often required. Compliance with pharmacopoeial standards like USP (United States Pharmacopeia) and BP (British Pharmacopoeia) further assures the quality and suitability of the material for medicinal use.

The sourcing and procurement of high-quality Propyleneglycol Alginate powder require careful consideration. Manufacturers specializing in pharmaceutical and food-grade raw materials are the primary source. They typically offer varying minimum order quantities (MOQ), which can range from as low as 1 kg for sampling or small-scale use up to bulk quantities of 25 kg drums, 1250 kg IBCs, or even larger volumes depending on production capacity, which can reach several tons per year. Packaging is designed to protect the integrity of the powder, often involving multi-layer bags or drums with inner liners to prevent moisture absorption and contamination during transport and storage.

When looking to buy Propyleneglycol Alginate, prospective customers should inquire about detailed product specifications, certifications, and available technical documentation. Understanding the supplier's quality control procedures and testing capabilities is crucial. Discussions about price per kilogram or per batch are standard, and competitive pricing is often available for larger orders. Finding a reliable supplier and manufacturer with a proven track record in producing high-purity Propyleneglycol Alginate is key to ensuring a stable and consistent supply chain for your production needs.

For those seeking to purchase Propyleneglycol Alginate CAS 9005-37-2 powder, engaging directly with experienced producers allows for detailed technical discussions and negotiation of terms. Whether your application is in pharmaceuticals, food processing, or specialized chemical formulations, securing a source that prioritizes purity, consistency, and compliance with relevant standards is paramount. Exploring options for bulk buy or specific packaging requirements can be facilitated through direct communication with a dedicated Propyleneglycol Alginate supplier.

In summary, Propyleneglycol Alginate CAS 9005-37-2 is a critical raw material valued for its functional properties as a thickener, stabilizer, and emulsifier. Its high purity and performance characteristics make it indispensable in a variety of products, particularly within the pharmaceutical and food sectors. Partnering with a reliable manufacturer ensures access to material that meets stringent quality benchmarks, supporting the production of safe and effective end products.
