CONCENTRATED SURFACTANT COMPOSITION

FIELD OF THE INVENTION

The present disclosure relates to concentrated surfactant compositions that include an alkyl alkoxylated sulfate surfactant and an alkoxylated polyalkyleneimine, and process for making such compositions. The present disclosure further relates to detergent compositions made from such concentrated surfactant compositions, and process for making such detergent compositions.

BACKGROUND OF THE INVENTION Concentrated surfactant compositions are useful for making detergent compositions, such as laundry or dish detergent compositions. Because they have high activity, they can be transported relatively efficiently. Furthermore, they can be combined and diluted with other detergent ingredients or carriers to arrive at a desired level of activity.

However, concentrated surfactant compositions, particularly those that contain a high proportion of anionic alkyl alkoxylated sulfate surfactant, may also present viscosity and/or stability challenges. The viscosity of such compositions may be relatively high, making the compositions difficult to pump or drain, for example from a rail car or from a storage tank to a manufacturing line. The compositions may also suffer from phase splits, which can lead to inconsistencies in the final product and/or aesthetic problems. Even upon dilution with water, concentrated compositions that include anionic alkyl alkoxylated sulfate surfactant may form a highly viscous hexagonal phase, which can be very challenging to process.

To counteract viscosity and/or stability issues, organic solvents may be added to the concentrated surfactant compositions. However, organic solvents may add cost without providing much performance benefit in the final product. There is a need for improved concentrated surfactant compositions that have a relatively high level of activity, limited solvents levels, and desirable viscosity and/or phase stability. SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure relates to concentrated surfactant compositions that contain a relatively high level of alkyl alkoxylated sulfate surfactant, such as alkyl ethoxylated sulfate surfactant ("AES"). Lamellar phase AES pastes are traditionally used due to their relatively stable phase profile. However, as the activity of these pastes increases to 60% and above, the rheology profiles of the pastes tend to increase significantly.

While organic solvents can be added to improve the viscosity and/or stability of the concentrated compositions, solvents typically add cost to a composition without adding performance benefits to final compositions. Furthermore, too much solvent can also lead to stability challenges when insufficient amounts of water are present.

Phase stability knowledge of AES molecules shows a hexagonal phase that forms at levels of about 30-60%, by weight of the composition, and a lamellar phase that forms above about 60% in the absence of solvent. Hexagonal phases are typically characterized by high viscosities and near-solid behavior, while lamellar phases are typically viscous but flowable. However, even the flowable lamellar phase rheology profiles may not be conducive to all transportation options, such as rail cars. It is desirable to be able to modify the rheology of these lamellar paste phases without impacting the cost of the material when used in product or negatively impacting the stability of the concentrated compositions.

The compositions of the present disclosure may include alkyl alkoxylated sulfate surfactant at levels near the top range of what is traditionally in the hexagonal phase, while still being flowable. The target viscosity of the present compositions may be even lower than is typical for lamellar phase AES compositions. The present compositions may have a viscosity of equal to or less than about 20,000cps, or less than about 15,000 cps at Is ¹ at 40°C (lOOOcps = 1 Pa-s).

It has been surprisingly found that alkoxylated alkyleneimine polymers, such as alkoxylated polyethyleneimines (PEIs), can be added to the concentrated composition to provide viscosity and/or stability benefits, thereby enabling the level of organic solvent to be decreased. Such polymers are commonly used in final products, such as laundry detergents, in combination with AES and provide more performance benefits, such as cleaning benefits, than organic solvents do. Spiking the concentrated compositions, which may be upstream in the manufacturing process, with these polymers enables the final product's activity level to remain relatively high without sacrificing formulation space or paying unnecessary cost.

The components and properties of the concentrated surfactant compositions of the present disclosure are described in more detail below. As used herein, the articles "a" and "an" when used in a claim, are understood to mean one or more of what is claimed or described.

Concentrated Surfactant Composition

The present disclosure relates to concentrated surfactant compositions. The compositions described herein may be intermediate compositions intended to be combined with other ingredients to form a final product. The concentrated surfactant compositions of the present disclosures are sometimes considered to be surfactant pastes.

The concentrated surfactant compositions may comprise, may consist essentially of, or may consist of the following components: a surfactant system that may include an alkyl alkoxylated sulfate surfactant; an alkoxylated polyalkyleneimine; an organic solvent system; and water. These components are described in more detail below.

The concentrated surfactant composition may comprise: from about 60% to about 69%, by weight of the composition, of a surfactant system, where the surfactant system comprises from about 70%, or from about 80%, or from about 90%, or from about 95%, to about 100%, of alkyl alkoxylated sulfate surfactant; from about 0.1% to about 5%, by weight of the composition, of an alkoxylated polyethyleneimine (PEI); less than about 10%, by weight of the composition, of an organic solvent system; and water. The composition may comprise no more than 2, or no more than 1, additional ingredients.

The concentrated surfactant composition may be in the form of a liquid, gel, and/or paste. Typically, the concentrated surfactant composition is not a solid composition, such as a granular or powdered composition. The concentrated surfactant composition may be non-particulate.

The concentrated surfactant compositions may have a viscosity of less than about 20,000 cps, or less than about 15,000 cps, or less than about 10,000 cps, or less than about 7,000 cps, measured at Is ¹ and 40°C. The concentrated surfactant compositions may have a viscosity of from about lOOcps, or from about 500cps, or from about lOOOcps, to about 20,000cps, or to about 15,000cps, or to about 10,000cps, or to about 7000 cps, measured at Is ¹ and 40°C. Having a relatively low viscosity may facilitate transporting, pumping, and/or processing the compositions. For example, viscosity of the concentrated composition may influence whether the composition is pumped out of a rail car via the top or bottom of the car. It may be desirable for the concentrated surfactant composition to be phase stable and/or have a clear appearance, as such compositions may be easier to process and/or incorporate into a final product. The concentrated surfactant composition may be isotropic, which can be indicative of the composition being phase stable. The concentrated surfactant composition may remain as a single phase, isotropic solution after 2 weeks at 20°C, and/or 2 weeks at 40°C. The concentrated surfactant composition may have a percent transmittance (%T) at 570nm of at least about 80%, or of at least about 85%, or of at least about 90%, or of at least about 95%, or of at least about 98%, or of at least about 99%. Percent transmittance is determined according to the Percent Transmittance method provided in the Test Methods section below. The concentrated surfactant composition may have an alkaline pH in a 10%

(weight/volume) solution of the composition at 20 + 2°C. The concentrated surfactant composition may be characterized by a pH greater than 8, or greater than 9, or greater than 10, or greater than 11, in a 10% (weight/volume) solution of the composition at 20 + 2°C. The concentrated surfactant composition may have a pH of from about 9 to about 13, or preferably from about 10 to about 13, in a 10% (weight/volume) solution of the composition at 20 + 2°C.

The concentrated surfactant composition may be characterized by a Reserve Alkalinity (RA) value. RA is a measure of the buffering capacity of the detergent composition

(g/NaOH/lOOg detergent composition) determined by titrating a 1% (w/v) solution of detergent composition with hydrochloric acid to pH 7.5 and is determined according to the method provided in the Test Methods section below. The concentrated surfactant composition may be characterized by a Reserve Alkalinity of less than about 2, or less than about 1.5, or less than about 1, or less than about 0.8. The concentrated surfactant composition may be characterized by a Reserve Alkalinity of from about 0.1, or from about 0.3, or from about 0.5, to about 2.0, or to about 1.5, or to about 1.0, or to about 0.8. Such Reserve Alkalinity can help to maintain the alkaline pH of the compositions described herein. Because alkyl alkoxylated sulfate surfactants can undergo acid-catalyzed hydrolysis reactions in acidic environments, it can be particularly desirable for compositions comprising such surfactants to have a certain Reserve Alkalinity.

Surfactant System

The concentrated surfactant compositions of the present disclosure comprise a surfactant system. The concentrated surfactant compositions may comprise from about 60% to about 69%, by weight of the composition, of a surfactant system. The surfactant system may comprise anionic surfactant. The anionic surfactant of the surfactant system may comprise, or consist essentially of, alkyl alkoxylated sulfate surfactant, linear alkyl benzene sulfonate surfactant, or mixtures thereof. The surfactant system may be substantially free of nonionic surfactant, cationic surfactant, amphoteric surfactant, and/or zwitterionic surfactant. The surfactant system may be substantially free of nonionic surfactant.

The surfactant system may consist essentially of no more than two types of surfactants. It is recognized, however, that the surfactant system may include minor portions of, for example, raw material inputs, hydrolyzed reaction products, or other impurities related to the surfactants making up the major portion of the surfactant system, or other impurities.

The surfactants present in the surfactant system may be present either partially or completely in acid form or as a salt, typically a water-soluble salt. Suitable counterions include alkali metal cation, typically sodium, or ammonium or substituted ammonium, typically sodium. The surfactants, either separately or together, may be preneutralized prior to being combined with one or more of the other components of the concentrated surfactant system.

When the alkyl alkoxylated sulfate surfactant is a mixture of alkyl alkoxylated sulfate surfactant, the alkoxylation degree is the weight average alkoxylation degree of all the components of the mixture (weight average alkoxylation degree). In the weight average alkoxylation degree calculation the weight of alkyl alkoxylated sulfate surfactant components not having alkoxylated groups should also be included. Weight average alkoxyylation degree is calculated in the following manner:

Weight average alkoxylation degree = (xl * alkoxylation degree of surfactant 1 + x2 * alkoxylation degree of surfactant 2 + ....) / (xl + x2 + ....) wherein xl, x2, ... are the weights in grams of each sulfated anionic surfactant of the mixture and alkoxylation degree is the number of alkoxy groups in each sulfated anionic surfactant.

The alkyl alkoxylated sulfate surfactant may be alkyl ethoxylated surfactant having a narrow range of ethoxylation. The alkyl ethoxylated surfactant may include a distribution of alkyl ethoxylated surfactants where less than about 7% by weight of the total alkyl ethoxylated surfactant are alkyl ethoxylated surfactant having n>3 and less than about 35% by weight of the total alkyl ethoxylated surfactant are alkyl ethoxylated surfactants having n=0, where n is the number of ethoxylates (EO) groups in the surfactant (AE _n S).

If the alkyl alkoxyalted sulfate is a branched alkyl alkoxylated sulfate, the branching group may be an alkyl. The alkyl may be selected from methyl, ethyl, propyl, butyl, pentyl, cyclic alkyl groups and mixtures thereof. Single or multiple alkyl branches could be present on the main hydrocarbyl chain of the starting alcohol(s) used to produce the sulfated anionic surfactant used in the detergent of the invention. The branched alkyl alkoxylated sulfated anionic surfactant may be an alkyl ethoxy sulfates.

Alkyl alkoxylated sulfate surfactants are commercially available with a variety of chain lengths, ethoxylation and branching degrees.

where B represents a continuation of this structure by branching. In some aspects, n+m is equal to or greater than 8, or 10, or 12, or 14, or 18, or 22.

The alkoxylated polyalkyleneimine polymer comprises alkoxylated nitrogen groups. The alkoxylated polyalkyleneimine polymer may independently comprise, on average per alkoxylated nitrogen, up to about 50, or up to about 40, or up to about 35, or up to about 30, or up to about 25, or up to about 20, alkoxylate groups.

The ratio of polyethylene blocks to polypropylene blocks (n/p) may be from about 0.6, or from about 0.8, or from about 1, to a maximum of about 10, or a maximum of about 5, or a maximum of about 3. The n p ratio may be about 2. The propoxylated polyalkylenimines may have PEI backbones having molecular weights (prior to alkoxylation) of from about 200 g/mol to about 1200 g/mol, or from about 400 g/mol to about 800 g/mol, or about 600 g/mol.

The polyamines may be "substantially noncharged," meaning that there are no more than about 2 positive charges for every about 40 nitrogens present in the backbone of the polyalkyleneamine polymer at pH 10, or at pH 7; it is recognized, however, that the charge density of the polymers may vary with pH.

Suitable alkoxylated poly alky leneimines, such as PEI600 EO20, are available from BASF (Ludwigshafen, Germany).

Organic Solvent System

The concentrated surfactant compositions of the present disclosure may comprise an organic solvent system. The organic solvent system may contribute to desirable viscosity and stability profiles in the compositions of the present disclosure. However, it may be desirable to keep the amount of solvent system as low as possible while still maintaining the desired viscosity and/or stability as the solvents add little to the performance benefits of the end product.

The organic solvent system may be present at a level of less than about 10%, or less than about 5%, or less than about 1%, by weight of the composition. The concentrated surfactant compositions may comprise from about 0% to about 10%, or from about 0% to about 5%, or from about 0% to about 1%, or about 0%, by weight of the composition, of an organic solvent system.

It is understood that water may also be formed from the neutralization of acids in the composition, for example, from acid-form alkyl ethoxylated sulfate (HAES) or acid-form LAS (HLAS).

Alkalizing Agent

The concentrated surfactant compositions of the present disclosure may comprise an alkalizing agent. The concentrated surfactant compositions may comprise from about 0.5% to about 5.5% of the alkalizing agent. The alkalizing agent may be present in the concentrated surfactant composition at a level sufficient to neutralize the surfactants. When the surfactants are neutralized, whether they enter the composition preneutralized or are neutralized by the addition of the alkalizing agent, a small amount of excess alkalizing agent may be present in the composition, for example, from about 0.1 % to about 1 % by weight of the concentrated surfactant composition.

The alkalizing agent may be a caustic agent. Suitable caustic agents include alkali metal hydroxides, alkali earth metal hydroxides, ammonium (substituted or unsubstituted) hydroxides, or mixtures thereof. The alkalizing agent may be an alkali metal hydroxide, preferably sodium hydroxide.

The process may comprise the steps of: providing a surfactant system, an alkoxylated poly alky leneimine, such as alkoxylated polyethyleneimine (PEI), an organic solvent system, and water; and combining the components in the following proportions to form the concentrated surfactant composition: from about 60% to about 69%, by weight of the composition, of an alkyl alkoxylated sulfate surfactant; from about 0.1% to about 5%, by weight of the composition, of the alkoxylated poly alky leneimine; less than 10%, by weight of the composition, of the organic solvent system; and water.

The process may include providing the alkyl alkoxylated sulfate surfactant and/or the linear alklyl benzene sulphonate surfactant in preneutralized form, preferably preneutralized with sodium. The process may include the step of combining the alkyl alkoxylated sulfate surfactant and/or the linear alklyl benzene sulphonate surfactant with the alkalizing agent to preneutralize the surfactant(s) prior to combining with the organic solvent system. The composition may include a small excess of the alkalizing agent, preferably a caustic alkalizing agent such as sodium hydroxide, beyond what is required to neutralize the surfactants, whether or not they are provided as being preneutralized. Therefore, the concentrated surfactant composition may comprise from about 0.1% to about 1%, by weight of the concentrated surfactant composition, of an alkalizing agent, preferably a caustic alkalizing agent such as sodium hydroxide. It may be desirable to preneutralize the surfactants so that the pH can be more tightly controlled.

Process for Manufacturing a Detergent Composition

The present disclosure relates to a process for manufacturing the detergent compositions. The detergent composition may have any form suitable for end use by a consumer, such as a liquid, a gel, a powder, a bar, a tablet, a unitized dose article such as a pouch (single- or multi- compartmented), a fiber, a web, or a sheet.

The process may comprise the steps of: providing a concentrated surfactant composition as described herein and combining the concentrated surfactant composition with at least one adjunct to form a detergent composition. The step of providing the concentrated surfactant composition may include the steps of preparing the concentrated surfactant composition at a first location and transporting the concentrated surfactant composition to a second location, and where the combining step occurs at the second location. The transporting may occur by rail car.

The concentrated surfactant compositions of the present disclosure are useful as surfactant intermediates that may be incorporated into different end-use detergent compositions. Therefore, the present disclosure relates to a process for manufacturing a plurality of detergent compositions, the process comprising the steps of: providing a first portion of the concentrated surfactant composition as described herein; combining the first portion with first detergent adjuncts to form a first detergent composition; providing a second portion of the concentrated surfactant composition as described herein; combining the second portion with second detergent adjuncts to form a second detergent composition that is compositionally different from the first detergent composition. For the processes described herein, the concentrated surfactant composition may be provided at a single batch and then divided in to first and second portions, but does not need to be. The first and second portions could be provided as separate batches, manufactured as separate places or separate times.

The second detergent composition may be different from the first detergent compositions in terms of the adjuncts added, the relative proportions in which the adjuncts and/or concentrated surfactant composition were added, pH, aesthetics (including color and/or perfume), or any other suitable compositional difference.

TEST METHODS

Viscosity

The viscosity is measured with a Rheometer, such as the AR G2 Rheometer from TA Instruments. Viscosity is measured using 40 mm 2° cone at a range of temperatures between 10- 60°C. Shear rates of 1 to 100 s ¹ are measured on a logarithmic scale with five points per decade.

Percent Transmittance

The Percent Transmittance is measured with a UV- Visible spectrometer such as a Beckman Coulter DU® 800. A standard 10 mm pathlength cuvette is used for the sample measurement and compared to a deionized water blank. Samples are measured in the in the absence of dyes and/or opacifiers, and at a temperature of 20°C + 2°C. pH

Unless otherwise stated herein, the pH of the composition is defined as the pH of an aqueous 10% (weight/volume) solution of the composition at 20 + 2°C. Any meter capable of measuring pH to + 0.01 pH units is suitable. Orion meters (Thermo Scientific, Clintinpark - Keppekouter, Ninovesteenweg 198, 9320 Erembodegem -Aalst, Belgium) or equivalent are acceptable instruments. The pH meter should be equipped with a suitable glass electrode with calomel or silver/silver chloride reference. An example includes Mettler DB 115. The electrode should be stored in the manufacturer' s recommended electrolyte solution.

The 10% aqueous solution of the detergent is prepared according to the following procedure. A sample of 10 + 0.05 grams is weighted with a balance capable of accurately measuring to + 0.02 grams. The sample is transferred to a 100 mL volumetric flask, diluted to volume with purified water (deionized and/or distilled water are suitable as long as the conductivity of the water is < 5μ8Λ;ιη), and thoroughly mixed. About 50 mL of the resulting solution is poured into a beaker, the temperature is adjusted to 20 + 2 °C and the pH is measured according to the standard procedure of the pH meter manufacturer. The manufacturer's instructions should be followed to set up and calibrate the pH assembly.

Reserve Alkalinity

As used herein, the term "reserve alkalinity" is a measure of the buffering capacity of the detergent composition (g/NaOH/lOOg detergent composition) determined by titrating a 1% (w/v) solution of detergent composition with hydrochloric acid to pH 7.5 i.e in order to calculate Reserve Alkalinity as defined herein:

Reserve Alkalinity (to pH 7.5) as % alkali in g NaOH/100 g product =

T x M x 40 x Vol

10 x Wt x Aliquot

T titre (ml) to pH 7.5

M Molarity of HC1 = 0.2

40 Molecular weight of NaOH

Vol = Total volume (ie. 1000 ml)

Wt Weight of product (10 g)

Aliquot = (100 ml) Obtain a lOg sample accurately weighed to two decimal places, of fully formulated detergent composition. The sample should be obtained using a Pascall sampler in a dust cabinet. Add the lOg sample to a plastic beaker and add 200 ml of carbon dioxide-free deionised water. Agitate using a magnetic stirrer on a stirring plate at 150 rpm until fully dissolved and for at least 15 minutes. Transfer the contents of the beaker to a 1 litre volumetric flask and make up to 1 litre with deionised water. Mix well and take a 100 mis ± 1 ml aliquot using a 100 mis pipette immediately. Measure and record the pH and temperature of the sample using a pH meter capable of reading to +0.01pH units, with stirring, ensuring temperature is 21°C +/- 2°C. Titrate whilst stirring with 0.2M hydrochloric acid until pH measures exactly 7.5. Note the millilitres of hydrochloric acid used. Take the average titre of three identical repeats. Carry out the calculation described above to calculate RA to pH 7.5.

EXAMPLES

The examples provided below are intended to be illustrative in nature and are not intended to be limiting. Example 1. Process of Making a Concentrated Surfactant Composition.

An ethoxylated alcohol is provided. The ethoxylated alcohol is sulfated by known processes to form alkyl ethoxylated sulfate surfactant. To this surfactant, the following are added in a neutralization loop while being mixed at high shear: organic solvent, ethoxylated PEI, water, and a neutralizing agent. Alternatively or additionally, the ethoxylated PEI may instead be added after the neutralization loop, with an additional high shear mixing step.

Example 2. Viscosity Comparisons.

As described below, various concentrated surfactant compositions were prepared and assessed for viscosity.

Sample Preparation. Each sample was prepared by mixing appropriate amounts of pre- neutralized Na-AES (70-78% active), pre-neutralized Na-LAS (78% active) where applicable, ethoxylated PEI (80% active), and water to balance in a speed mixing vessel to provide the compositions described below in Tables 1-3. The samples were then mixed in the speed mixer at 2400 rpm for two minutes. The samples were then transferred into a centrifuge and spun at 4400 rpm for one hour to remove excess air. Viscosity. The samples were measured for rheology on an ARG2 machine using a 113μιη initial gap and 63μιη test gap, 5 minute equilibrium time, and sheared from 1 to 100 s ¹ at various temperature points. Results are shown in Tables 1-3 below.

Ingredients:

C24AE3S CI 2- 14 alkyl ethoxy sulfate surfactant having an average of 3 ethoxy groups (sodium-neutralized)

C25AE1.8S CI 2- 15 alkyl ethoxy sulfate surfactant having an average of 1.8 ethoxy groups (sodium-neutralized)

C45AE2.5S C14-15 alkyl ethoxy sulfate surfactant having an average of 2.5 ethoxy groups (sodium-neutralized)

LAS linear alkyl benzene sulphonate surfactant (sodium-neutralized) PEI 1 Ethoxylated polyethyleneimine (PEI600 EO20, ex BASF)

Table 1.

The results in Table 1 show the effect of an alkoxylated PEI on decreasing the low shear rheology of a concentrated AES composition. When the total amount of active ingredients are kept at approximately 70%, viscosity at about Is ¹ (40°C) decreases about 70% in the compositions that include the alkoxylated PEI. Table 2.

The results in Table 2 show the viscosity-lowering benefits of an alkoxylated PEI on concentrated surfactant compositions (active ingredients: approx. 70%) that include a mixture of surfactants (AES and LAS). Table 3.

The results in Table 3 show that a concentrated surfactant composition that includes AES, LAS, and an alkoxylated PEI has reduced viscosity at 20°C compared to a similar composition that does not contain LAS. Without wishing to be bound by theory, it is believed that the combination of AES and LAS results in a reduced melt point of the composition, providing a composition that can more easily be processed due to the lower viscosity.

Example 3. PEI Levels.

A pre-neutralized surfactant composition containing 66% total surfactant (100% AES) is heated to 50°C and then combined with an alkoxylated PEI polymer (PEI600 EO20, ex BASF) in varying amounts (from about 0% to about 6%) and water to balance. The samples are stirred using overhead agitation. The samples are then de-aerated by storing overnight to 60°C.

Afterwards, the samples are analyzed for rheology using an ARG2 rheometer with a 40cm 2° cone and plate geometry. Results for viscosity measured at Is ¹ at 40°C vs. amount of PEI are shown below in Table 4.

Table 4.

As shown by the results displayed in Table 4, a surfactant composition having approximately 0.5% of a PEI as described herein is characterized by significantly lower viscosity at Is ¹ at 40°C compared to a similar composition that is free of a PEI. Additionally, the data shows that the optimum amount, from a rheology perspective, of PEI in the surfactant composition is about 1% PEI; adding more than about 1% PEI to the surfactant composition does not appear to significantly change the viscosity further under the given test conditions. That being said, more than 1 % PEI may be desirable for improved performance in end-use cleaning compositions, such as a laundry detergent. Example 4. Surfactant Levels.

Surfactant compositions are prepared according to Example 3, but in Example 4, the level of PEI is kept constant (about 1%), and the level of surfactant (AES) is varied. The viscosity results are shown in Table 5. Table 5.

As can be seen by comparing the results in Table 5 to the comparative examples shown above (e.g., Table 1, comparative examples A and E), concentrated AES compositions having an alkoxylated PEI have lower viscosities at Is ¹ at 40°C compared to compositions that do not include such alkoxylated PEIs. Further, as can be seen in the results displayed in Table 5, compositions having from about 63% to about 66% AES and an alkoxylated PEI show

particularly favorable (i.e., low) viscosities, especially compositions having about 64% AES.

Example 5. Heavy Duty Liquid Laundry Detergent Compositions.

Concentrated surfactant compositions according to the present disclosure are used to make heavy duty liquid laundry detergent compositions according to the following formulas, as shown in Table 6.
