Tomadol Ethoxylated Alcohols Product Guide

We have been providing that edge for over 40 years. This product guide offers a good starting point providing an overview of our ethoxylated alcohols and alkoxylated nonionic surfactants.

For free samples or technical assistance please call us at You can also visit our web site at www. Our complete range of Tomadol Ethoxylated Alcohol surfactants are made from linear synthetic alcohols, and are named to indicate the structure of the surfactant. These well-known surfactants are represented by the structure in Table 1 and include names of the general format Tomadol CC-n surfactant, where CC represents the number of carbon atoms present in the alkyl group R of the linear alcohol, and n indicates the average moles of ethylene oxide.

As an example, the product Tomadol surfactant is made from a distribution of C9, C10, and C11 linear alcohols with an average of 6 moles of ethylene oxide. In order to optimize the performance of these products, they may include a range of natural-derived alcohols and ethoxylate distributions. Tomadol,surfactants are high-performance, environmentally-friendly nonionic surfactants designed specifically for ease of reformulation when replacing alkyl phenol ethoxylates.

The first number within the product name, or two numbers in the case of Tomadol surfactant, corresponds to the number of moles of ethylene oxide within the alkyl phenol ethoxylate to be replaced. Within Industrial and Institutional cleaning, these products can provide equal or better performance than APE in a wide variety of formulations and are often used at a lower amount than the level of APE in the original cleaning formulation.

These products are designed for applications requiring minimum foam levels, fast wetting, free rinsing characteristics, and high emulsification. They are excellent wetting agents, emulsifiers, and detergents. The Tomadol L Series are moderate foamers. These synthetic alcohols include one alcohol with a single carbon cut, and four that are a distribution of carbon chain lengths.

Typical properties for the alcohols are provided in Table 6. With the exception of the C linear alcohol, all of the synthetic linear alcohols used to produce the Tomadol Ethoxylated Alcohol surfactants are pourable at room temperature.

Tomadol Ethoxylated Alcohols Tomadol ethoxylates are colorless and range from liquids to low melting point solids of pasty consistency. They are excellent wetting agents, emulsifiers, and detergents, and are moderate foamers. Typical physical and chemical properties of Tomadol Ethoxylated Alcohols are provided in Table 8.

Pour point is one indication of the ease of handling of a nonionic surfactant and indicates if heated storage is required. If clarity of a formulation at use is desirable, the cloud point may indicate the approximate maximum temperature range for the application of the surfactant. Surfactant systems with intermediate HLB number, pour point, and cloud point can be obtained by blending appropriate amounts of higher and lower EO-containing Tomadol Ethoxylated Alcohols.

The base-catalyzed condensation reaction of ethylene oxide EO with an alcohol gives a mixture of ethylene oxide adducts of varying chain length. The composition of the mixture follows a standard distribution curve, peaked at the average EO content. Table 7 provides additional detail on this distribution and should help the formulator in selecting the appropriate Similar to crowdtap Ethoxylated Alchol surfactant for their application.

The Tomadol 25 alcohol ethoxylates are recommended for general purpose high-performance applications. Tomadol 91 and Tomadol 1 alcohol ethoxylate series, with shorter hydrophobic chains, are faster wetting agents and have improved handling properties, such as lower pour points, easier dilution properties, and good compatibility in liquid concentrates. The Tomadol 1 series ethoxylates are intermediate to the Tomadol 25 series and the Tomadol 91 series. As illustrated in Figure 19, the Tomadol 91 series surfactants have relatively low viscosities near room temperature and consequently are easy to pump and handle.

Viscosities of the Tomadol 1 series surfactants exhibit very similar low viscosities and also offer excellent handling characteristics. In general, the lower the viscosity at a given temperature, the easier the material is to pump. Many nonionic surfactants require heating to lower the viscosity to a level that is readily pumpable under practical conditions. Tomadol 80 60 Tomadol 40 20 Tomadol Table 9 illustrates the viscosity of some of the Tomadol Ethoxylated Alcohol surfactants at varying concentration in water.The present invention relates to an improved hydrotrope for liquid detergent compositions.

In particular, the invention relates to a novel and synergistic hydrotrope that is a combination of a polyethylene glycol ether of glycerin and an alcohol ethoxylate and is useful for surfactant based detergent compositions.

Liquid detergent compositions are used in a variety of cleaning activities. For example, they are used to machine wash and hand wash clothes, dishes, hard surfaces such as walls and glass, and automotive surfaces.

Generally, each use dictates different desired performance characteristics for each type of detergent composition. For example, it is desired that liquid detergents used to machine wash clothes or dishes do not generate a high volume of foam because excessive foam can inhibit cleaning efficacy and be difficult to remove from the washing machine. On the other hand, it is desired that a detergent composition used to hand wash clothes, dishes, or automobiles and similar vehicles generate foam because the perception of cleaning quality is directly related to foam volume in these applications.

At the same time, the detergent composition should be easily dispersed, particularly when incorporated in an aqueous carrier, and have an appropriate viscosity, i.

To accomplish these and other objectives, it is known to add hydrotropes; for example an alcohol such as ethanol. Unfortunately, the use of ethanol raises flammability concerns and also tends to produce compositions that develop a skin on standing because of evaporation of the hydrotrope. Moreover, if more than a minimal amount of ethanol is required to prevent gelling, the compositions may impart the typical odor of ethanol that is difficult to cover with fragrances.

Thus, there is always a need for a detergent composition that satisfies a variety of performance characteristics such as foam generation, dispersability and viscosity control, compatibility with other formulation components, environmental safety and cost effectiveness. The novel hydrotrope is a combination of a polyethylene glycol ether of glycerin and an alcohol ethoxylate that synergistically provides improved performance characteristics beyond that which would be expected from their additive effects.

The main detergent surfactant includes at least one surfactant selected from the group consisting of anionic, nonionic, amphoteric surfactants and mixtures thereof. The anionic surfactant includes but is not limited to the sulfated anionic surfactants, sulfonated anionic surfactants, sulfosuccinates, sulfosuccinamates, taurates, isethionates, salts of fatty acids, carboxylated alcohol ethoxylates, ether sulfates and combinations thereof. The nonionic surfactant includes but is not limited to the alkanolamides, amine oxides, alkoxylated alcohols, alkoxylated phenols, block polymers and co-polymers, alkoxylated amines, alkyl polysaccharides, glucosamides, sugar esters and combinations thereof.

The amphoteric surfactant includes but is not limited to the monoacetates, diacetates, betaines, glycinates, imidazolines, imidazoline derivatives, monopropionates, dipropionates, hydroxy sultaines and combinations thereof.

Although the foam-enhancing agent may be the same as one or more of the surfactants included as part of the main surfactant, typically the foam-enhancing agent will be different.

The foam-enhancing agent is typically selected from the group consisting of amine oxides, amides, alkyl glucosides, and mixtures thereof. The hydrotrope of the present invention can be used in conjunction with or to replace in whole or in part these foam-enhancing surfactants. Preferably, the hydrotrope of the present invention is used in conjunction with these foam-enhancing surfactants. In this instance, the presence of the hydrotrope of the present invention provides foam generation greater than without the presence of the novel hydrotrope.

In addition, the hydrotrope of the present invention can be used to replace in whole or in part the known hydrotropes such as the alcohols, diols, and triols. Generally, the ratio of the polyethylene glycol ether of glycerin to the short-chain alcohol ethoxylate ranges from about to aboutpreferably from about to aboutand more preferably from about to about In one embodiment, the hydrotrope consists essentially of a mixture of a polyethylene glycol ether of glycerin and a short-chain alcohol ethoxylate where they are the only added hydrotrope constituents present in the composition.

In this regard, it is known that some surfactants such as ether sulfates, when commercially supplied, contain low molecular weight alcohols, such as ethanol, which if added to a detergent composition may be considered a hydrotrope. These low molecular weight alcohols are incorporated in the commercial products so that they are free-flowing liquids. Thus, in this embodiment, when it is stated in the specification and claims that the hydrotrope consists essentially of a mixture of a polyethylene glycol ether of glycerin and a short-chain alcohol ethoxylate where they are the only added hydrotrope constituents present it is meant to exclude any added alcohol, diol, or polyol as a hydrotrope but is not meant to exclude low molecular weight alcohol e.

Thus, it is not meant to exclude any ethanol that is present in a commercially available surfactant such as an ether sulfate. In other words, the resulting composition is substantially free or completely free from other added hydrotropes excluding those present as a result of surfactant manufacturing such as ethanol present in commercially available ether sulfates. In this embodiment, the main detergent surfactant is preferably selected from the group consisting of anionic and nonionic surfactants and mixtures thereof.

More preferably, the main detergent surfactant comprises predominantly one or more nonionic surfactants with the balance being one or more anionic surfactants. The present invention is also directed to an improved liquid detergent composition containing one or more surfactants selected from the group consisting of anionic, nonionic, amphoteric surfactants and mixtures thereof, wherein the improvement comprises an effective amount of a hydrotrope to provide increased foam generation ability to the composition and wherein the hydrotrope comprises a mixture of an alcohol ethoxylate and an ethoxylated glycerin.

The present invention also includes a method of increasing the foam generation ability of a liquid detergent composition that comprises the step of adding an effective amount of a hydrotrope to the liquid detergent wherein the liquid detergent includes one or more surfactants selected from the group consisting of anionic, nonionic, amphoteric surfactants and mixtures thereof and wherein the hydrotrope is a mixture of an alcohol ethoxylate and an ethoxylated glycerin.Nonylphenol and its ethoxylates NP and NPEs have been used for more than 40 years as detergents, emulsifiers, wetting agents and dispersing agents.

Nonionic surfactant can be defined as a surface active agent that does not dissociate into charged ions in solution.

This contrasts with anionic and cationic surfactants which have negative and positive charges in solution. They are the most preferred detergents as compared to ionic surfactants due to their insolubility in many hard water and cationic surfactants due to poor cleaning characteristics.

Moreover, in terms of detergency, nonionic surfactants exhibit low foam properties, outstanding solvency and absolute chemical stability. Nonionic surfactant products are friendly on the dermis even at greater loadings and exposure. They include fatty acid ethoxylates, fatty amine ethoxylates, fatty alcohol ethoxylates, nonylphenol ethoxylates, alkyl phenol ethoxylate, amide ethoxylates, and glyceride ethoxylates castor oil or hydrogenated castor oil ethoxylates.

Fatty alcohol ethoxylates, range from very clear - yellowish liquid - waxy solids. This depends on the length of alkyl chain and the apparent number of ethoxy groups.

Non ionic surfactants contain both hydrophobic tail portion and hydrophilic polar head groups. Thus tend to dissolve in both aqueous and oil phase reducing the surface tension of liquids. Ethylene oxide is a simple cyclic epoxide or ether C2H4O ; the addition of reactive material to the base of alcohols forms ethoxylated surfactants. Using more hydrophilic groups brings about better solubility in water since more hydrogen bonding exists. They do not dissociate in solution i. This means that the surfactant will work well in hard water and at low temperatures.

Moreover, they exhibit more stability in acidic and alkali solution plus miscibility with other surfactants. Fatty alcohol ethoxylates surfactants find application in Industries as detergents, dispersants, stabilizers, anti-foaming agents e. Ethoxylated fatty amines are also non-ionic surfactants which are mostly used as emulsifiers and emulsifier blend formations.

Their application includes; the making of wetting agents, sanitizers, dispersants, stabilizers, and anti-foaming agents. Fatty amine ethoxylates are considered as a useful an intermediate for the synthesis of anionic surfactants. They have a wide application. However, their cationic characteristics have extended their use of these compounds and have brought out novel and valuable means for handling a lot of industrial problems.

The properties they display are very important in petroleum refinery processes. For instance, a continuous injection of minor amounts of polyoxyethylated amine into the refinery processes protects metal surfaces from reacting with water, hydrogen chloride and hydrogen sulfide. In addition, metallic and mineral surface may absorb the cationic surfactant.

Fatty amine ethoxylates find their useful application in dye leveling and as wetting agents in textile industries and industrial detergents. Fatty Acid Ethoxylates are their primary use as non-ionic surfactants in a number of processes in the industrial and domestic boundaries. With reference to their low ability foam and low comparative cost, polyoxyethylene fatty acid ester have been the most attractive non-ionic detergent product in the market.

When combined with different types of builders, these surface active agents are ingredients for a majority of domestic and industrial cleaning applications.

Fatty acid ethoxylates are also applied as cleansing agents, dispersants emulsifierswetting agents water softeners and spin dying agents in textile Industries. However, they are used as dispersants and solubilizes in cosmetics and health care industrial applications. Fatty acid ethoxylates includes; stearic acid ethoxylates, lauric acid ethoxylates and coco fatty acid ethoxylates. These products are used in textile and in the manufacture of spin finishes.

In conclusion, ethoxylates are the essential building molecules for a lot of the highly valued detergents and surfactants accessible to consumers globally. There are also natural oil ethoxylates and alkyl phenol ethoxylates.

Some others, such as dust-control agents and deicers, lead to direct release to the environment. NPEs, though less toxic and persistent than NP, are also highly toxic to aquatic organisms, and, in the environment, degrade into NP. NP and NPEs are produced in large volumes, with uses that lead to widespread release to the aquatic environment. NP is persistent in the aquatic environment, moderately bioaccumulative, and extremely toxic to aquatic organisms.

NP has also been shown to exhibit estrogenic properties in in vitro and in vivo assays. NP and NPEs have been found in environmental samples taken from freshwater, saltwater, groundwater, sediment, soil and aquatic biota.

NP has also been detected in human breast milk, blood, and urine and is associated with reproductive and developmental effects in rodents. The phase out would end the use of NPEs in industrial laundry detergents by for liquid detergents and for powder detergents. Contact Us to ask a question, provide feedback, or report a problem.
