Spiga Nord > Polyglycerols for the food and cosmetics esters sector
Spiga Nord produces its vegetable polyglycerols exclusively by polycondensing vegetable glycerine. The raw material meets the specifications for the food additive E422 under Commission Regulation (EU ) 2023/1329.
This production approach provides a raw material with high purity and consistent quality. It also supports the development of ingredients for both food and cosmetic applications.
Formulators do not typically add polyglycerols directly as finished ingredients. Ester manufacturers use them as building blocks. Through esterification with fatty acids or other organic acids, they produce a wide range of emulsifiers, emollients and functional ingredients for the food and personal care markets.
Spiga Nord controls the entire production chain and offers a comprehensive range of plant-based polyglycerols. Ester manufacturers can therefore select the degree of polymerisation that best meets their formulation and processing requirements.
Food and cosmetic ester development requires raw materials with highly consistent properties.
The oligomeric distribution of polyglycerol directly affects the performance of the final ester. Raw material purity and production reproducibility also play an essential role. Together, these factors influence emulsifying capacity, stability, viscosity, hydrophilicity and formulation behaviour.
Manufacturers must therefore select the appropriate polyglycerol for each application. This choice influences the development of food emulsifiers such as E475 Polyglycerol Esters of Fatty Acids and E476 Polyglycerol Polyricinoleate (PGPR). It also affects a wide range of cosmetic esters for skincare, haircare and personal care products.
Spiga Nord addresses these requirements with a comprehensive range of polyglycerols. The company produces them exclusively from E422-compliant vegetable glycerine. Spiga Nord controls their oligomeric distribution and maintains consistent quality across production batches. These characteristics give customers a reliable foundation for developing innovative, high-performance ingredients.
Spiga Nord’s polyglycerols serve as the starting point for synthesising numerous esters used in the food and cosmetics industries.

Ester manufacturers primarily use low-polymerisation polyglycerols to produce food-grade esters.
The Spiga Nord range includes:
These products provide suitable building blocks for the synthesis of E475 and E476. Food manufacturers widely use these two emulsifiers in a broad range of applications.
Spiga Nord offers a complete range of polyglycerols for cosmetic ester production. The products feature different degrees of polymerisation. Their different chain lengths allow formulators to develop emulsifiers and functional ingredients with specific properties, including:
The product range includes:
Spiga Nord offers the Polyglycerine-10 family in several oligomeric compositions: PG10S, PG10 Standard and PG10L. The company also provides a formulation containing 10% water. This option reduces viscosity and simplifies handling and transport. Customers can therefore select the composition that best supports the development of new cosmetic ingredients.
Spiga Nord ranks among the few manufacturers that offer a complete range of plant-based polyglycerols. The company develops these products specifically for food and cosmetic ester production.
Spiga Nord produces its polyglycerols exclusively from vegetable glycerine that meets the specifications for the food additive E422. This approach delivers consistent quality and high purity. The production process uses no glycidol for ingredients intended for the most demanding markets.
Spiga Nord controls the oligomeric distribution across the entire product range. The company also maintains consistent production standards and provides extensive formulation flexibility. Customers can therefore select the polyglycerol that best matches the required characteristics of the final ester.
Spiga Nord supports customers with dedicated technical assistance. The company also provides Halal, Kosher and COSMOS certifications. These services help manufacturers develop innovative ingredients for the food and personal care markets.
Spiga Nord views polyglycerol as more than a raw material. It represents the starting point for new solutions. From diglycerol to the Polyglycerine-10 family, the company offers a comprehensive technology platform for the development of next-generation food and cosmetic esters.
