Chemistry: Our starting fatty alcohols could have linear or branched alkyl chains: for the linear chain we choose raw materials exclusively of renewable origin, whereas the branched chain is of petrochemical origin.
Ethylene oxide and propylene oxide could also be present in the same molecule: in this case we produce block derivatives, where ethylene oxide and propylene oxide are added in different steps, or random derivatives where ethylene oxide and propylene oxide are added in parallel.
Applications: The performance properties of the ethoxylated derivatives can be widely changed depending on the alkyl chain length and on the number of the ethylene oxides units linked to the alkyl chain.
According to their hydrophilic-lipophilic balance (link to nonionic surfactants) our fatty alcohol ethoxylates can be used in many different applicative sectors as water in oil and oil in water emulsifiers or wetting/cleansing agents.
Other important applications are as solubilizers (for the personal care sector) or rheology modifiers (for the vinyl chloride emulsion polymerization).
The presence of the polyoxypropylene chain and its location in the chemical structure can bring some additional properties. In particular it may lead to the decreasing of the foaming power (to obtain for example low foam detergents), to the decreasing of the pour point or to the improving of the emulsifying power.
