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 )

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

ADJUVANTS: Agrochemicals

• Improving biological performance of a pesticide is a becoming more and more important in Crop Protection to optimize the amount of pesticide applied, improve handling and safety by applicators and consumers.

• Adjuvants can enhance the performance of the pesticide by affecting the penetration into leaf or soil (wetter) , or by improving rain fastness by prolonging the activity of the pesticides (spreader and sticker), or by reducing drift during spray application (anti-drift).

• Lamberti can provide a wide portfolio of adjuvants designed for the most selective applications. For example: – combinations of surfactants in

the form of emulsions and micro emulsions (e.g. patented MICROBIO)

– our patented "green products" like EUCAROL AGE (alkylpolyglucoside esters) that are made from naturally derived materials
