Properties

BTC’s product portfolio covers the following petrochemical nonionic surfactants for chemical-technical applications:

Disponil® NRG grades (modified fatty alcohol ethoxylates) are nonionic surfactants. They are aqueous solution based on fatty alcohol ethoxylates with high degree of mols EO. In addition they provide improved process behavior in comparison to the standard fatty alcohol ethoxylates. No gelling phase will occur during further processing with water. Colloidal systems often need stabilization inert to avoid coalescence. Disponil® NRG grades fulfill the needs of a stabilizing additive.

Emulan® grades (C13 oxo alcohol ethoxylates) are nonionic surfactants. They are either liquid formulations, waxy substances, waxy micronized beads or flakes. The products have versatile properties like solubilizing, wetting, dispersing, and soil removal.

Lutensol® XP grades (C10-Guerbet alcohol ethoxylates) are nonionic surfactants. They are alkyl polyethylene glycol ether based on C10 Guerbet alcohol and ethylene oxide. They are available with a low, medium and high EO degree. Dependent on their EO degree the non diluted grades are cloudy liquids or yellowish pastes which become clear at 50°C. Water diluted grades, indicated by the index XP ..9, are clear liquids at room temperature. The products provide excellent dynamic and wetting properties. Contrary to other nonionic surfactants the XP types provide high cmc values (critical micelle concentration).

Lutensol® XL grades (C10-Guerbet alcohol alkoxylates) are nonionic surfactants. They are alkyl poly alkoxylates. Dependent on their EO degree the non diluted grades are cloudy liquids or slightly yellowish pastes which become clear at 50°C. The water diluted grades, indicated by the index XL ..9, are clear liquids at room temperature. The products provide excellent wetting properties and solubilizing properties. Formulations with sensivity to odour can be prepared with such grades due to their lower smelling character.

Lutensol® TO grades (C13-oxo alcohol ethoxylates) are nonionic surfactants. They are based on saturated iso-C13-alcohol. They provide a low, medium and high EO degree. EO degree of medium and high are water-diluted grades to keep the liquid form. According to their structure they are used where wetting, emulsification and soil removal power is needed.

BTC’s product portfolio covers the following oleochemical nonionic surfactants for chemical-technical applications:

Agnique® CSO grades (castor oil ethoxylates) are nonionic surfactants. They are ethoxylates based on castor oil providing various degrees of EO numbers. Due to their molecular structure they are offering emulsification and dispersing properties.

Agnique® SPO grades (Sorbitan ester ethoxylated) are nonionic surfactants. They are ethoxylates of sorbitol, also known as glucitol, which is a sugar alcohol. Properties of emulsification as well as dispersing are provided.

Agnique® FOH grades (C16-18 unsaturated fatty alcohol ethoxylates) are nonionic surfactants. They are alkyl polyethylene glycol ether based on native unsaturated fatty alcohol. They are available with low and medium EO-degree. Agnique® FOH grades provide excellent emulsification properties.

Disponil® A grades (modified fatty alcohol ethoxylates) are nonionic surfactants. They are modified alkyl polyethylene glycol ethers with improved process behaviour in comparison to the standard fatty alcohol ethoxylates. They are available from medium EO degree to high EO degree. All products are water diluted and therefore liquid solutions. The active matter content is depending on the EO degree and varies from 65% to 80%. Due to their molecular structure they provide emulsification and stabilizing properties. With high ethoxylation degree, the stabilizing properties of Disponil® A grades are stronger.

Disponil® AFX grades (modified fatty alcohol ethoxylates) are nonionic surfactants. They are modified alkyl polyethylene glycol ethers with improved process behaviour in comparison to the standard fatty alcohol ethoxylates. They are available from medium EO degree to high EO degree. All products are water diluted and therefore liquid solutions. The active matter content is depending on the EO degree and varies from 30% to 80%. Due to their molecular structure they provide emulsification and stabilizing properties. With high ethoxylation degree, the stabilizing properties are stronger. According to their performance they are substitutes for banned alkyl aryl phenol ethoxylates.

Disponil® APG grades (alkyl polyglucoside) are nonionic surfactants. They are alkyl polyglucosides made from saturated native alcohol and glucose. The used linear alcohol chain varies from C8-10, and C8-14. Due to their structure they provide stabilization properties.

Disponil® NG (modified fatty alcohol ethoxylate) is a nonionic surfactant. It is a modified ethoxylate based on a native fatty alcohol and exhibits improved dilution properties in comparison with standard fatty alcohol ethoxylates.

Disponil® PGE (modified fatty alcohol ethoxylate) is a nonionic surfactant. It is a polyglycol ether of an aliphatic diol with an EO degree of 10 mols. It is a liquid product almost free of water. It’s active matter content is 100%. Due to the molecular structure it provides best stabilization properties.

Disponil® OC grades (C16-18 unsaturated fatty alcohol ethoxylates) are nonionic surfactants. They are alkyl polyethylene glycol ethers based on native unsaturated fatty alcohol. Thus their C-chain is linear and even numbered. They are available with low and medium EO-degree. Disponil® OC grades provide excellent emulsification properties.

Emulan® grades (modified fatty alcohol ethoxylates) are nonionic surfactants. They are either liquid formulations, waxy substances, waxy micronized beads or flakes. Emulan® grades have versatile properties like solubilizing, wetting, soil removal as well as strong dispersing properties.

Eumulgin® (C16-18 fatty alcohol ethoxylate) is a nonionic surfactant. Eumulgin® is based on native alcohol and consists of different moles of EO. It is a viscous liquid product. Eumulgin® provides properties like dispersing and emulsification.

Lutensol® AT grades (C16-18 fatty alcohol ethoxylates) are nonionic surfactants. They are alkyl polyethylene glycol ethers made from a linear, saturated C16-18 fatty alcohol. They are available from medium EO degree to high EO degree. Due to their chemical constitution the grades are solid and available in powder or flake form. Lutensol® AT grades provide emulsification as well as dispersing properties.

Considering the alkyl chain and the degree of ethoxylation respectively alkoxylation the properties change with respect to chain lengths and alkoxylation degree. The detergency qualities are key factors in home care I&I formulations whereas they are of less importance in chemical-technical formulations. Here stabilizing and dispersing properties are key. Thus the main differences are related to the alkyl structure and alkoxylation degree. The latter varies from medium to high. Alkyl polyglucosides are nonionic surfactants without ethoxylated units and give strong foaming properties whereas other nonionics provide less foaming properties. In general, nonionic surfactants are either 100% active or water-diluted solutions depending on their alkoxylation degree. Further dilution with water is possible. In some cases extra energy is needed to overcome the gelling phase. In addition to the less sensivity of water hardness nonionics are less sensitive against pH values. They do not decompose in acidic or alkaline conditions.

Applications

The variety of chemical-technical applications in the industry induces the use of nonionic surfactants to stabilize a formulation or provide dispersing and lubricating properties.

With our versatile product grades we offer outstanding nonionic surfactants which provide the requested quality. For example, in emulsion polymerization (Disponil®) the latex needs to be stabilized. The stabilizing effect is stronger by using steric repulsion which is provided by nonionics with medium to high alkoxylation degree. In addition the impact of water hardness and pH value is negligible. Crop formulations (Agnique®) are a further example. Here the nonionic surfactant is primary used as an emulsifier. In addition it supports the performance of the pesticide.
