Polyglycerols for the Construction Industry

Spiga Nord’s vegetable polyglycerols are polyols obtained exclusively through the polycondensation of vegetable glycerine that complies with the specifications for food additive E422.

This choice ensures a raw material of high purity, consistent quality, and full suitability for developing ingredients intended for both the food and cosmetics industries.

Unlike esters, polyglycerols are not typically used as final ingredients in formulations, but rather serve as the building blocks from which—through esterification with fatty acids or other organic acids—numerous emulsifiers, emollients, and functional ingredients used in the food and personal care markets are derived.
Thanks to the full integration of its production chain, Spiga Nord offers the most comprehensive range of plant-based polyglycerols available on the market, allowing ester manufacturers to choose the degree of polymerisation best suited to their formulation needs.

The Challenges Facing the Food & Cosmetics Industry

Developing food and cosmetic esters requires raw materials with extremely consistent properties.

The oligomeric distribution of polyglycerol, the purity of the starting raw material, and the reproducibility of the production process directly influence the performance of the final ester, determining properties such as emulsifying capacity, stability, viscosity, hydrophilicity, and formulation behaviour.
For this reason, the choice of polyglycerol is a fundamental factor in the development of food emulsifiers such as E475 (Polyglycerol Esters of Fatty Acids) and E476 (Polyglycerol Polyricinoleate—PGPR), as well as a wide range of cosmetic esters used in skincare, haircare, and personal care products.

Spiga Nord meets these needs with a comprehensive range of polyglycerols made exclusively from E422-compliant vegetable glycerine, with controlled oligomeric distributions and consistent quality from batch to batch, giving customers a solid foundation for developing innovative, high-performance ingredients.

Esterification

Food Esters

E475, E476

Cosmetic Esters

E.g.: Polyglyceryl-x Oleate, Polyglyceryl-x Stearate, Polyglyceryl-x Laurate…

Food Applications

Low-polymerisation-degree polyglycerols are the primary raw material used to produce food-grade esters.

The lineup includes:

  • Pure Vegetable Diglycerin (PG2)
  • Pure Vegetable Polyglycerin-3 (PG3)
  • Pure Vegetable Polyglycerin-4 (PG4)

These products are particularly well-suited for the synthesis of E475 and E476, two of the most widely used emulsifiers in the food industry.

Cosmetic Applications

For the production of cosmetic esters, Spiga Nord offers a complete range of polyglycerols with varying degrees of polymerisation; in fact, the different chain lengths make it possible to develop emulsifiers and functional ingredients with different characteristics in terms of:

  • HLB
  • hydrophilicity/lipophilicity
  • viscosity
  • sensory experience
  • emulsifying capacity

The lineup includes:

  • Pure Vegetable Diglycerin
  • Pure Vegetable Polyglycerin-3
  • Pure Vegetable Polyglycerin-3em
  • Pure Vegetable Polyglycerin-4
  • Pure Vegetable Polyglycerin-6
  • Pure Vegetable Polyglycerin-10
  • Pure Vegetable Polyglycerin-10, Diluted

The Polyglycerine-10 family is available in various oligomeric compositions (PG10S, PG10 Standard, and PG10L), as well as a version diluted with 10% water (to reduce viscosity and facilitate transport), offering customers maximum flexibility in developing new cosmetic ingredients.

Why Choose Spiga Nord

Choosing Spiga Nord means relying on one of the few manufacturers that can offer a complete range of plant-based polyglycerols, developed specifically for producing food and cosmetic esters.

Our polyglycerols are derived exclusively from vegetable glycerine that complies with the specifications for food additive E422, ensuring consistent quality, high purity, and the complete absence of glycidol in the production process for ingredients intended for the most demanding markets.

The entire product line is designed to offer controlled oligomeric distribution, consistent production, and maximum formulation flexibility, allowing you to identify the most suitable polyglycerol based on the characteristics required for the final ester.

To support our customers, we also provide dedicated technical assistance and certifications—including Halal, Kosher, and COSMOS—helping manufacturers develop innovative ingredients for the food and personal care markets.

For Spiga Nord, polyglycerol is not simply a raw material, but the starting point for creating new solutions. From diglycerol to the Polyglycerine-10 family, we offer a comprehensive technology platform to support our customers in developing the next generation of food and cosmetic esters.

FAQ

Polyglycerols are polyalcohols obtained through the polycondensation of glycerine. They serve as the starting raw material for the production of numerous esters used as emulsifiers and functional ingredients in the food and cosmetic industries.
Generally not. Polyglycerols are used as building blocks and are subsequently esterified with fatty acids or other organic acids to obtain ingredients intended for final use, such as food esters E475, E476, or Polyglyceryl Esters for cosmetic applications.
Diglycerine (PG2), Polyglycerine-3, and Polyglycerine-4 are mainly used for the production of food esters, employed to obtain emulsifiers such as E475 and E476.
The entire Spiga Nord range can be used in the production of cosmetic esters. The choice of degree of polymerization depends on the desired properties of the final ester, such as HLB, emulsifying capacity, viscosity, and sensory profile.
All Polyglycerols are obtained exclusively from refined vegetable Kosher Halal glycerine compliant with the specifications of food additive E422, ensuring high purity, vegetable origin, and consistent quality.
The Polyglycerine-10 family is available with different oligomeric distributions. The PG10S (Short), PG10 Standard, and PG10L (Long) versions allow the characteristics of the final ester to be optimized according to specific formulation requirements. A Polyglycerine-10 Diluted version is also available, designed to facilitate product handling and transfer thanks to a significant reduction in viscosity.
