Nonionic Surfactants

Elementis Specialties offers a broad range of nonionic surfactants. Alcohols, oils, fatty acids, amines and alkanol amides can be coupled with ethylene oxide and/or propylene oxide enabling the production of ethoxylates, propoxylates, and random and block co-polymers.

Nonionics are applied in a wide variety of applications and their function is strongly dependent on the chemical composition. The choice of nonionic for a specific application is primarily determined by the hydrophilic/lipophilic balance (HLB). The HLB value dictates properties such as emulsification power, detergency, foaming, solubilisation and others. The table provides indicative values of required HLB’s for the most common applications.


Surfactants Capabilities

Elementis Specialties has the capabilities to offer designed chemical solutions for specific applications: The HLB value of the nonionic surfactants can be tuned by the length of the alkyl chain and the amount, ratio and order of EO and PO units. Nonionics can be tailor-made with high precision with regard to the average number of EO and/or PO units. Additionally, specific requirements for nonionic surfactants - such as biodegradability, mildness, ionic character, etc. - can be met by choosing a particular starting material, i.e. fatty alcohol, acid or amine.


ALKYL POLYGLYCOL ETHERS


Alkyl polyglycol ethers are stable in acidic and alkaline media and can be combined with anionic and cationic surfactants for synergistic effects.

OIL/ACID POLYGLYCOL ESTERS


Elementis Specialties offers alkoxylated oils and fatty acids, as well as alkyl polyglycol esters. These products are generally mild for skin and eyes and have good emulsifying, softening, lubricating and antistatic properties, making them useful as emulsifiers for essential oils, cosmetics, textile, leather, paper and agricultural products.

AMINE POLYGLYCOL ETHERS


Amine polyglycol ethers are nonionic surfactants which exhibit a cationic character under acidic conditions. These cationic properties can be tuned by the length of the hydrophilic polyglycol ether chain (amount of EO) and offer valuable means for solving various industrial challenges.

Amine polyglycol ethers provide adhesion, antistatic, corrosion inhibiting and leveling properties, and are therefore highly suitable to use in auxiliary products for various industries like agro, textile, oil-drilling metal and industrial cleaning.

ALKANOLAMIDES (ETHOXYLATED)

Elementis Specialties offers (ethoxylated) alkanolamides based on various fatty acids and monoethanolamine or diethanolamine. The products based on diethanolamine can be subdivided into two groups:

Super-amides based on a 1:1 molar ratio of amine to fatty acid.

Kritchevsky amides based on a 2:1 molar ratio of amine to fatty acid. This type is better soluble in water.

Alkanolamides can be used as anti-static agents for plastics and as emulsifiers for detergents, mineral oils and cosmetic formulations.

IMIDAZOLINES


Imidazolines are thermally stable and easy to handle liquids. The un-neutralised imidazoline is soluble in non-polar solvents and mineral oil, but only dispersible in aqueous systems. Due to the ability of imidazolines to form cations they strongly absorb onto the negatively charged surfaces such as metals, fibres, glass and minerals and thereby convert the hydrophilic surfaces to hydrophobic ones.

Imidazolines find main applications in adhesion agents for bitumen (heat stability) and corrosion inhibitor formulations.
