EUCAROL AGE
Lamberti has created a new generation of anionic surfactants called EUCAROL
AGE, characterised by good biological efficacy and environment friendly
performance. The range includes:
EUCAROL AGE SS ( Disodium Cocopolyglucose Sulfosuccinate)
EUCAROL AGE EC ( Disodium Cocopolyglucose Citrate )
EUCAROL AGE ET ( Sodium Cocopolyglucose Tartrate )
DERIVED FROM
NATURAL, RENEWABLE

EUCAROL AGE
EUCAROL AGE are free from Ethylene Oxide, 1,4 Dioxane e Nitrosamines, toxic impurities present in
standard surfactants.
Shown below are the simplified chemical structure of EUCAROL AGE SS compared with a traditional
ethoxylated fatty alcohol sulfosuccinate. The polyoxyethylene chain, which is the hydrophylic part in the
traditional molecule and can generate free EO and 1,4 dioxane, is substituted by glucose units.
Moreover, differently from common amphoteric surfactants, EUCAROL AGE does not contain nitrogen
atoms, precursor of nitrosamines.

CHEMICAL-PHYSICAL PROPERTIES
• The low surface tension at the Critical Micelle Concentration
(CMC) highlights the effectiveness of the products as surface-
active agents
• CMC value is low compared with other anionic surfactants;
i.e. lower concentration of monomers – surface-active
molecules not associated in micelles which leads to lower
toxicity
