is best for your needs.
Because Spiga Nord directly manufactures pharmaceutical-grade glycerol and controls every stage of the process, from production and quality control to packaging and warehousing. This integrated approach enables the company to maintain consistent supply quality over time.
Spiga Nord’s refined glycerin is used in a wide range of products: from cosmetic, food, and pharmaceutical formulations to the tobacco industry, toothpastes, polyurethanes, paint resins, and explosives.
Certainly.
Thanks to its fifty years of experience in producing refined glycerin, Spiga Nord is able to manufacture a pharmaceutical-grade refined glycerol characterized by high chemical and microbiological purity, and the absence of substances harmful to humans such as diethylene glycol and related compounds, residual solvents, mycotoxins, pesticides, and heavy metals.
The product “Glycerol Eur. Ph. min. 99.5% vegetable origin – Excipient” complies with monograph 0496 of the European Pharmacopoeia and is also produced and distributed in accordance with the applicable GMP guidelines for pharmaceutical excipients.
Furthermore, the systems used for managing company operations (ERP) and analytical data (LIMS) have been validated in accordance with the applicable GAMP requirements.
Certainly.
The product “Glycerol Eur. Ph. min. 99.5% vegetable origin” can be used as an ingredient in cosmetic formulations and also complies with the requirements set by COSMOS and ECOCERT FRANCE for cosmetic raw materials.
Certainly.
Spiga Nord’s refined glycerin is obtained exclusively from GMO-free vegetable crude glycerine (with no BSE/TSE risk) purchased from qualified suppliers. It also complies with the requirements set by COSMOS and ECOCERT FRANCE for cosmetic raw materials of natural origin.
Certainly.
Spiga Nord can handle individual supplies and deliveries of finished product throughout Italy and worldwide, in quantities ranging from 25 kg to 28 tons, depending on the Customer’s needs.
The packaging used (jerrycans, metal drums, IBCs, tank trucks for bulk product) is qualified and suitable to meet the requirements of the pharmaceutical and food sectors.

Certainly.
Their vegetable origin enables formulators to incorporate them into 100% natural finished products. This characteristic offers particular value in cosmetic applications, where dermatological and environmental concerns increasingly call the use of ethoxylated derivatives into question. Polyglycerol esters enable formulators to create emulsions without ethoxylated compounds.
They also meet the requirements established by COSMOS and ECOCERT FRANCE for cosmetic raw materials.
During research and development, manufacturers must ensure that the product retains its stability and functionality throughout its entire shelf life. In particular, cosmetic products must preserve their consistency, fragrance, softness and rapid absorption during use. Together with other formulation components, polyglycerol esters help manufacturers achieve both objectives.
Formulators can use them as non-ionic emulsifiers, dispersing agents, emollients, humectants or thickening agents in personal care products.
Certainly.
Manufacturers can use Spiga Nord’s Polyglycerols to produce esters that comply with the specifications outlined in European Regulation 2023/1329 for the food additives E475 POLYGLYCEROL ESTERS OF FATTY ACIDS and E476 POLYGLYCEROL POLYRICINOLEATE, as well as with the requirements established by 21 CFR 172.854 for the food additive POLYGLYCEROL ESTERS OF FATTY ACIDS.
Polyglycerol esters perform several functions in food products. They act as emulsifiers, fat replacers, and processing aids that help preserve the food’s rheological properties.
The reaction of polyglycerol with fats, oils, or fatty acids produces E475. The resulting product may contain mono-, di-, and triglycerides, along with free glycerol and fatty acids.
Food manufacturers widely use fatty acid esters as structuring agents, complexing agents, humectants, anti-foaming agents, and anti-splatter agents.
Polyglycerol polyricinoleate primarily acts as a viscosity-modifying agent.
It also helps stabilize emulsions in oil–water systems with a very high water content.
For example, the additive E476 effectively maintains the integrity of chocolate in food coatings.
Certainly.
Manufacturers use polyglycerol, and more commonly its esters, in polymer production for several purposes. As plasticizers, they provide the finished product with new and specific rheological properties. Manufacturers can add them directly during bulk or suspension polymerization or introduce them during the final production stages. As anti-fog agents, they migrate toward the polymer surface without moving outside the product itself. They also act as lubricants, thanks to their ability to maintain high viscosity even at elevated temperatures.
Certainly.
Spiga Nord’s polyglycerols are non-toxic and do not harm the environment. These characteristics make them suitable for use in drilling fluids, hydraulic fluids, and lubricants for technical fluid applications. They also comply fully with current environmental safety regulations.
Certainly.
Formulators use polyglycerol esters in detergent formulations because they act as effective emulsifiers and non-ionic surfactants. Detergents work by capturing greasy substances, which generally have a lipophilic affinity, and dispersing them within an aqueous medium.
Polyglycerol esters with a high HLB value can significantly improve the performance of oil-in-water emulsions with a high water content. They act as surfactants and help stabilize the emulsion.
Spiga Nord’s Polyglycerols enable manufacturers to produce natural esters. Spiga Nord produces them exclusively by polycondensing refined vegetable glycerine sourced from qualified suppliers. The glycerine complies with Kosher and Halal requirements, contains no GMOs, and carries no BSE/TSE risk.
Certainly.
A key feature of these products lies in their ability to create emulsifiers with a specific HLB (Hydrophilic–Lipophilic Balance). Formulators can achieve the desired balance by selecting the appropriate polyglycerol and fatty acid, defining their proportions, and carefully controlling the operating conditions.
Certainly.
Polyglycerols contain fewer hydroxyl groups within their molecular structure and have a higher molecular weight than glycerol. As a result, the skin generally tolerates polyglycerols and their esters well.
Certainly.
Spiga Nord manages individual orders and delivers finished products throughout Italy and worldwide. Customers can request quantities ranging from 25 kg to 28 tons according to their specific requirements.
