Product overview

What are NEODOL alcohols and ethoxylates? 

NEODOL alcohols are high purity, high linearity primary alcohols that typically contain 75-85% by weight normal alcohols. They contain both even and odd numbered carbon chains, offering excellent product qualities for various applications.

NEODOL alcohols are manufactured using the Shell hydroformylation (SHF) process from olefins produced from ethylene using the Shell Higher Olefins Process (SHOP). The alcohols are then reacted with ethylene oxide to produce NEODOL ethoxylates.

Shell chemicals companies offer a wide variety of alcohols and ethoxylates. The principal alcohol grades are NEODOL 91 (C9-C11 alcohols), NEODOL 23 (C12-13 alcohols), NEODOL 25 (C12-15 alcohols), NEODOL 45 (C14-15 alcohols), NEODOL 135 (C11-13-15 alcohols), Neodol 1, (C11 alcohol), Neodol 3, (C13 alcohol), and Neodol 5, (C15 alcohol).

Both alcohols and ethoxylates are product groups. Generic formula for alcohols is CnH(2n+1)OH often referred to as 'ROH'. Generic formula for ethoxylates is RO(CH2CH2O)nH.

How are NEODOL alcohols and ethoxylates used? 

NEODOL alcohols and ethoxylates are found in a wide variety of everyday products. NEODOL ethoxylates and other NEODOL-based surfactants are used in many of the most respected consumer detergents, cleaning products and personal care products worldwide. They are formulated into laundry powders and liquids, dishwashing liquid and hard surface cleaners. They are also used in the manufacture of a variety of industrial chemicals and in lubricating oil additives.

NEODOL alcohols and ethoxylates are often derivatised before use in formulations. The ease of ethoxylation and sulfation by conventional means makes the derivatives suitable for a broad spectrum of surfactant applications.

Datasheets

As shown in the table below, the NEODOL alcohols are named based on the number of carbon atoms contained in the product. For example, NEODOL 91 is a blend of C9, C10 and C11 alcohols.

For the NEODOL ethoxylates, the description of the parent alcohol is retained, e.g. NEODOL 91, and is followed by a number indicating the average moles of ethylene oxide (EO) added.

Applications

NEODOL alcohols and ethoxylates have diverse end-uses. Within the range of C7 to C17 alcohols, Shell chemicals companies offer a wide variety of alcohols and ethoxylates containing blended carbon chains to satisfy customer needs.

The surfactant market continues to undergo major changes and the NEODOL product range has been and will be adapted to serve changing needs. More than one NEODOL product is frequently suggested for a given end-use. In the final analysis, the customer will be required to choose the best product for a particular application.

By adjusting the ratio of the NEODOL surfactants, and sometimes by combining with other surfactant types, formulations can be optimised for such features as detergency, foam profile, builder type, enzyme stability, cold water performance and product multi-functionality.

Laundry products 

Laundry detergency is the capability of a surfactant system to remove soils and stains from fabrics. Three types of products derived from NEODOL alcohols and ethoxylates play major roles in laundry detergency processes: alcohol sulphates, alcohol ethoxy sulphates and ethoxylates. In this regard, Shell chemicals companies respond to customers' needs by offering NEODOL alcohols and ethoxylates for sulphation and ethoxylates for direct formulation into finished detergents.

A NEODOL product may be chosen for a particular formulation for a variety of reasons: superior detergency for particular soils, compatibility or synergism with other surfactants or enzymes, cost/performance, and satisfactory supply position. Biodegradability characteristics must be satisfactory, and the surfactant must perform well with a particular builder or, in some cases, no builder at all. Many other selection criteria are also involved.

Light Duty Liquid Detergents (LDLs) 

Most consumers judge the effectiveness of LDL detergents by dishwashing foam stability. Therefore, this performance criterion is quantitatively measured when judging the effectiveness of a particular LDL. Product appeal is also governed by other physical characteristics such as viscosity, low temperature stability, grease cutting ability, odour, appearance and skin mildness.

While Shell chemicals companies do not supply NEODOL-based ethoxysulphates, they do supply a variety of sulphation-grade ethoxylates for sulphation, i.e. NEODOL 23-2, NEODOL 25-3. In addition, mid-mole ethoxylates such as NEODOL 23-6.5 may be sulphated for use in liquid detergents.

Outstanding dishwashing foam performance can be obtained with liquids based on ethoxysulphates derived from NEODOL ethoxylates in combination with other ingredients such as alkyl benzene sulphonate, alpha olefin sulphonate and fatty acid diethanol amide. NEODOL alcohol ethoxylates offer the advantage of good grease-cutting performance and suitable skin mildness.

Hard Surface Cleaners 

NEODOL ethoxylates and ethoxysulphates are widely used to formulate hard surface cleaners such as pine oil cleaners, all-purpose cleaners, bathroom cleaners, floor and wall cleaners, and all-purpose spray cleaners.

The NEODOL 91, 1 and 23 series of ethoxylates are excellent candidates for hard surface cleaning applications. NEODOL 91 ethoxylates are often the most suitable for starting formulations. NEODOL 1 series ethoxylates offer excellent rinsing properties. In some cases, the NEODOL 23 and 25 ethoxylates are also suitable. An alcohol ethoxysulphate, such as one based on NEODOL 25-3, is often an appropriate choice where a higher foaming anionic surfactant is required. NEODOL 1, 91 and 23 alcohols can be ethoxylated to suit formulation needs.

Lubricating Oil Additives 

NEODOL alcohols are suitable for the manufacture of a number of commonly used additives in lubricating oils. They are used as a raw material for viscosity index improvers and as pour point depressants by major producers of additives in both Europe and the United States.
