Justia Patents Multifunctional Assembly (e.g., Package With Detergent And Prespotter In Separate Containers, Etc.)US Patent for Compacted liquid laundry detergent composition Patent (Patent # 10,655,093)
Jun 2, 2016 - The Procter & Gamble Company
The present invention is to the field of liquid laundry detergent compositions and their methods of use.
Liquid laundry detergent compositions with low equilibrium relative humidities have the advantage of being less susceptible to microbial contamination. There is also a trend towards so called compacted liquids that minimise the presence of unnecessary ‘filler’ liquids such as water. Such compositions are more environmentally friendly as less unnecessary material needs to be transported, so reducing the environmental impact of such transport operations. Therefore, there is a move in the industry to using so called compacted liquids which minimise the levels of non-active materials such as water. Such liquid laundry detergent compositions require both the presence of anionic surfactant such as linear alkylbenzene sulphonate and other non-surfactant cleaning and/or care actives.
The present invention is also to a liquid laundry detergent composition of comprising;
b. between 0.5% and 15% by weight of the liquid detergent composition of a solid cellulosic polymer,
wherein the solid is dispersed within the liquid phase and wherein the water-soluble solid phase is defined as the solid obtained when the liquid laundry detergent composition is centrifuged at 1200 G for 10 mins; and
wherein the liquid phase comprises between 5% and 40% by weight of the liquid of an alcohol selected from the group comprising ethylene glycol, 1,3 propanediol, 1,2 propanediol, tetramethylene glycol, pentamethylene glycol, hexamethylene glycol, 2,3-butane diol, 1,3 butanediol, diethylene glycol, triethylene glycol, polyethylene glycol, glycerol formal, dipropylene glycol, polypropylene glycol, dipropylene glycol n-butyl ether, and mixtures thereof, preferably the alcohol is selected from the group comprising 1,2 propanediol, dipropylene glycol, polypropylene glycol, 2,3-butane diol, dipropylene glycol n-butyl ether and mixtures thereof; and
wherein the composition comprises between 0.5% and 50% by weight of the composition of water; and
from 0% to 25% by weight of the composition of a non-ionic surfactant;
The liquid laundry detergent composition of the present invention comprises a liquid phase and a solid cellulosic polymer. The solid is dispersed within the liquid phase. Suitable cellulosic polymers are described in more detail below. The solid and liquid phases are described in more detail below.
Preferably, the liquid laundry detergent composition has a viscosity of between 300 mPa·s and 700 mPa·s, more preferably between 350 mPa·s and 600 mPa·s at a shear rate of 1000 s−1. An exemplary method for measuring viscosity is to use a Rheometer DHR1 from TA instruments using a gap of 1000 μm at 20° C. as according to the manufacturer's instructions.
The liquid laundry detergent composition of the present invention is preferably opaque. Without wishing to be bound by theory, consumers prefer opaque compositions as this signals excellent cleaning. By opaque we herein mean the composition has a fresh hunter L value of greater than 70, more preferably greater than 72, more preferably greater than 75. The Hunter colour space is organized as a cube. The L axis runs from top to bottom; the maximum L being 100 which is white and the minimum value is zero, which is black. The a and b axes have no specific numerical limits, however positive a is red, negative a is green, positive b is yellow and negative b is blue (see FIG. 1). Delta values (ΔL, Δa and Δb) can be measured and are associated with a colour change. The total colour difference, ΔE, can also be calculated. The ΔE is a single value that takes into account the differences between the L, a and b of test and comparison samples. The ΔE is calculated as follows;
Using L1, a1, b1 and L2, a2 and b2
ΔE=√(L2−L1)2+(a2−a1)2+(b2−b1)2
The instrument is used as per the manufacturer's instructions. A sample of 20 mL are tested in an optically clear glass cell having a fixed path length of 10 mm and dimensions 55 mm by 57 mm. The measurement type is reflectance measurement RSIN, which measures the diffuse and specular reflectance of the sample at the port. The measurements are made with the specular exclusion port door closed.
The liquid laundry detergent composition of the present invention overall is liquid in nature. That is to say, even though it comprises a solid dispersed within a liquid phase, the composition has the nature of a liquid rather than a solid or granular composition. In relation to the laundry detergent composition of the present invention, the term ‘liquid’ encompasses forms such as dispersions, gels, pastes and the like. The liquid composition may also include gases in suitably subdivided form. However, the liquid composition excludes forms which are non-liquid overall, such as tablets or granules.
The term ‘liquid laundry detergent composition’ refers to any laundry detergent composition comprising a liquid capable of wetting and treating fabric e.g., cleaning clothing in a domestic washing machine,
The liquid composition may be formulated into a unit dose article. The unit dose article of the present invention comprises a water-soluble film which fully encloses the liquid composition in at least one compartment. Suitable unit dose articles are described in more detail below.
The liquid laundry detergent composition can be used as a fully formulated consumer product, or may be added to one or more further ingredient to form a fully formulated consumer product. The liquid laundry detergent composition may be a ‘pre-treat’ composition which is added to a fabric, preferably a fabric stain, ahead of the fabric being added to a wash liquor.
The liquid laundry detergent composition comprises from 0% to 25% by weight of the composition of a non-ionic surfactant.
The liquid laundry detergent composition comprises between 0.5% and 20% by weight of the composition of water and may have an equilibrium relative humidity of less than 65% at 20° C.
Without wishing to be bound by theory, it is believed that the removal of the hydroxyl-containing amine compounds results in a number of detergent ingredients to come out of solution. This in turn results in increase viscosity of the composition. The present invention carefully balances the form of the ingredients between liquid and solid form so resulting a composition of acceptable viscosity.
Furthermore, removal of the hydroxyl-containing amine can cause the formulation to phase split (i.e. at least two visibly distinct phases can be seen). The present invention provides the additional benefit of providing a composition having a low relative humidity and lower levels of alcohol containing amine compounds, whilst minimising phase splitting.
Solid Cellulosic Polymer
The liquid laundry detergent composition of the present invention comprises between 0.5% and 15% by weight of the liquid detergent composition of a solid cellulosic polymer, wherein the solid cellulosic polymer is dispersed in the liquid phase. Preferably the cellulosic polymer is partially or completely water-soluble.
Cellulosic polymers made provide softening, cleaning, other care benefits or mixtures thereof. Preferably the cellulosic polymer provides a softening benefit, more preferably a softening benefit whilst maintaining excellent cleaning benefit.
By ‘solid’ we herein mean any material that is solid, i.e. not liquid. The solid may be in particulate form. The term ‘particles’ is herein used in its broadest meaning. The particles may have a mean particle size distribution of between 2 μm and 50 μm.
By ‘water-soluble’ we herein mean at least 75%, or even at least 85% or even at least 95% of the solid dissolves in water as measured by the method set out here after using a glass-filter with a maximum pore size of 20 microns:
5 grams±0.1 gram of solid is added in a pre-weighed 3 L beaker and 2 L±5 ml of distilled water is added. This is stirred vigorously on a magnetic stirrer, Labline model No. 1250 or equivalent and 15 cm magnetic stirrer, set at 600 rpm, for 30 minutes at 35° C. Then, the mixture is filtered through a folded qualitative sintered-glass filter with a pore size as defined above (max. 20 micron). The water is dried off from the collected filtrate by any conventional method, and the weight of the remaining material is determined (which is the dissolved or dispersed fraction). Then, the percentage solubility or dispersability can be calculated.
The water-soluble solid can be obtained when the liquid laundry detergent composition is centrifuged at 1200 G for 10 mins. A preferred method is;
2. 85 ml polycarbonate with screw lids test tubes are used. Each tube was filled with 50 g of material and the total mass: tube+lid+testing material measured
The liquid laundry detergent composition may comprise between 0.5% and 10%, or even between 0.5% and 7.5% or even between 0.5% and 5% by weight of the liquid laundry detergent composition of the solid cellulosic polymer.
The carboxymethyl cellulose may have a degree of substitution (DS) of from 0.01 to 0.99 and a degree of blockiness (DB) such that either DS+DB is of at least 1.00 or DB+2DS-DS2 is at least 1.20. The substituted carboxymethyl cellulose can have a degree of substitution (DS) of at least 0.55. The carboxymethyl cellulose can have a degree of blockiness (DB) of at least 0.35. The substituted cellulosic polymer can have a DS+DB, of from 1.05 to 2.00.
The hydrophobically modified carboxyethyl cellulose may have repeating substituted anhydroglucose units that correspond to the general Structural Formula I as follows:
The cationic cellulose polymers of Structural Formula I likewise include those which are commercially available and further include materials which can be prepared by conventional chemical modification of commercially available materials. Commercially available cellulose polymers of the Structural Formula I type include those with the INCI name Polyquaternium 10, such as those sold under the trade names: Ucare Polymer JR 30M, JR 400, JR 125, LR 400 and LK 400 polymers; Polyquaternium 67 such as those sold under the trade name Softcat SK™, all of which are marketed by Amerchol Corporation, Edgewater N.J.; and Polyquaternium 4 such as those sold under the trade name: Celquat H200 and Celquat L-200, available from National Starch and Chemical Company, Bridgewater, N.J. Other suitable polysaccharides include hydroxyethyl cellulose or hydoxypropylcellulose quaternized with glycidyl C12-C22 alkyl dimethyl ammonium chloride. Examples of such polysaccharides include the polymers with the INCI names Polyquaternium 24 such as those sold under the trade name Quaternium LM 200 by Amerchol Corporation, Edgewater N.J. Cationic starches described by D. B. Solarek in Modified Starches, Properties and Uses published by CRC Press (1986) and in U.S. Pat. No. 7,135,451, col. 2, line 33-col. 4, line 67.
The solid phase may comprise a carboxymethyl cellulose and a hydrophobically modified hydroxyethyl cellulose. Preferably, the ratio of carboxymethyl cellulose to hydrophobically modified hydroxyethyl cellulose is between 5:1 and 1:5, preferably between 3:1 and 1:3, more preferably between 3:1 and 2.5:1. The carboxmethyl cellulose and hydrophobically modified hydroxyethyl cellulose may be present in the same particles, different particles or a combination thereof. Without wishing to be bound by theory it was surprisingly found that the combination of carboxymethyl cellulose and hydrophobically modified hydroxyethyl cellulose provided excellent softening, especially over multiple wash cycles whilst maintaining excellent cleaning to fabrics.
Without wishing to be bound by theory, a further advantage of the present invention is minimising swelling of the cellulosic polymer. There is a tendency for cellulosic polymers to swell in the presence of solvent, causing further unacceptable increases in viscosity. The present invention carefully regulates the type of solvent used in the presence of the cellulosic polymer (i.e. specific alcohol of the present invention) to minimise the swelling effect of the cellulosic polymers.

The liquid laundry detergent composition comprises from 10% to 30% by weight of the composition of a non-amine neutralized linear alkylbenzene sulphonate. The linear alkylbenzene sulphonate may be present in the liquid or may be present as a solid, or a mixture thereof. If the linear alkylbenzene sulphonate is present as a solid, preferably it is in the form of a lamellar liquid crystal alkylbenzene sulphonate. By ‘lamellar liquid crystal’ we herein mean the system being in a state where the surfactant molecules are organised in stacks of bilayers of surfactant in the melted state separated by thin layers of solvent. This structure has both liquid properties in term of flowability as well as solid properties in term of being structured. The structure is characterised by its d-spacing, the sum of the bilayer thickness and the solvent layer between sheets.

Castor oils may include glycerides, especially triglycerides, comprising C10 to C22 alkyl or alkenyl moieties which incorporate a hydroxyl group. Hydrogenation of castor oil, to make HCO, converts the double bonds which may be present in the starting oil as ricinoleyl moieties. As such, the ricinoleyl moieties are converted into saturated hydroxyalkyl moieties, e.g., hydroxystearyl. The HCO herein may be selected from: trihydroxystearin; dihydroxystearin; and mixtures thereof. The HCO may be processed in any suitable starting form, including, but not limited to those selected from solid, molten and mixtures thereof.

A preferred method for measuring the eRH of the composition is via the composition eRH test. The composition eRH test comprises the steps of adding a sample of the composition to a calibrated Rotronic Hygrolab meter (in a plastic sample liner of 14 mm depth) at room temperature (20° C.+/−1° C.) and allowing this to equilibrate for 25 minutes, and finally measuring the eRH recorded. The volume of sample used was sufficient to fill the plastic sample liner.
The liquid laundry detergent composition may comprise an adjunct ingredient. The liquid laundry detergent composition may comprise from 20% to 40% by weight of the composition of an adjunct ingredient. The adjunct ingredient may be selected from the group comprising bleach, bleach catalyst, dye, hueing dye, cleaning polymers including alkoxylated polyamines and polyethyleneimines, surfactant, solvent, dye transfer inhibitors, chelant, enzyme, perfume, encapsulated perfume, soil release polymers, polycarboxylate polymers, brighteners and mixtures thereof.

In such an embodiment, the water-soluble unit dose article comprises at least one water-soluble film shaped such that the unit-dose article comprises at least one internal compartment surrounded by the water-soluble film. The at least one compartment comprises the liquid laundry detergent composition. The water-soluble film is sealed such that the liquid laundry detergent composition does not leak out of the compartment during storage. However, upon addition of the water-soluble unit dose article to water, the water-soluble film dissolves and releases the contents of the internal compartment into the wash liquor.
A preferred process comprises the step of adding the solid phase wherein the solid phase comprises particles wherein the particles have a mean particle size distribution of less than 500 μm.
HCO premix may be formed by melting HCO and adding into a small volume of a hot liquid laundry detergent composition wherein the composition does not comprise enzymes or perfume materials. The HCO premix is then added to other ingredients to form the liquid laundry detergent composition.

The compositions were made by preparing a 1 L beaker having an IKA Eurostar 200 mixer with 10 cm impeller. This was operated at 250 rpm. To the beaker with the rotating impellar, the solvent materials were added, followed by the surfactant materials. Once these had dispersed, the polymers and salts were added. The pH of the composition was adjusted using NaOH to approximately & (measured using a Sartorius PT-10 pH meter). Remaining ingredients were then added and mixed. All materials were weighed out using a Mettler Toledo PB3002-S balance.
The viscosity of the compositions were then measured using a Rheometer DHR1 from TA instruments using a gap of 1000 μm at 20° C. Samples were equilibrated for 1 min at 0.05 s−1 followed by a measured flow curve from 0.05 s−1 to 1200 s−1 over 10 mins. Results for 0.05 s−1 and 1000 s−1 are shown in Table 2.

Shear at 0.05 s−1 corresponds to that experienced by the composition during pouring of the composition by the consumer. Shear at 1000 s−1 corresponds to that experienced by the composition during manufacture.
Composition C which comprises 6.25% monoethanolamine shows an acceptable viscosity profile at low and high shear corresponding to consumer pouring shear and process dosing shear. However, when the monoethanolamine is removed in composition A (and correspondingly the surfactants are neutralized with sodium carbonate), there is an increase in viscosity to unacceptable levels.
