Description

HOME CARE COMPOSITIONS AND METHODS BACKGROUND

[0001] Fragrance is a key performance characteristic of cleaning compositions. When consumers compare two cleaning products, such as bucket-dilutable cleaners, that have the same base formula but different fragrances, they often rate the product that has the more pleasant fragrance as a better cleaner. Consumers may also rate products with a more intense and / or longer-lasting fragrance as a better cleaner.

[0002] Current market cleaning products most commonly contain total active ingredient blends of anionic and nonionic surfactants above 1%, measured by weight of the composition. The active ingredient blends are used for Bucket Dilutable Cleaning (BDC) applications. It is difficult to emulsify some fragrance oils, which are commonly present in higher amounts in BDC’s than other home care products, while lowering the total active ingredient levels to below 1% by weight of the composition.

[0003] Two cleaning compositions containing the same amount and type of fragrance, however, may not have the same fragrance performance (e.g., hedonic tone, release, long lastingness). Specific formula components such as surfactants, polymers and salts, for example, can interact with and impact fragrance performance. The traditional approach used to address any negative impact resulting from the interaction between formula ingredients and fragrance components has been to modify the composition of the fragrance to compensate for shortcomings in fragrance performance driven by the formula. However, depending upon cost and availability, modifying the composition of a fragrance, such as increasing the amount, may not be cost-effective or feasible. Accordingly, there is a desire in the art to increase fragrance performance in cleaning compositions without modifying the composition of a fragrance.

[0004] There is a need for a bucket-dilutable cleaning composition with a lower total amount of surfactant system (active ingredients, “Al,”) that maintains lasting fragrance.BRIEF SUMMARY

[0005] The present disclosure provides a turbidity-modified, fragrance-enhanced cleaning composition. In an implementation, such a cleaning composition comprises: an amphotericsurfactant, wherein the amphoteric surfactant comprises cocamidopropyl betaine (CAPB), wherein the CAPB is present in the cleaning composition in an amount of about 0.25% by weight; one or more nonionic surfactants in an amount of about 0.28% by weight; and a fragrance.

[0006] It has been surprisingly and unexpectedly discovered that emulsifying equivalent amounts of fragrance oils in some blends of amphoteric and nonionic surfactants delivers acceptable cleaning performance to similar compositions with equivalent amounts of fragrance oils emulsified in blends of anionic and nonionic surfactants. The composition comprising a blend of amphoteric and nonionic surfactants exhibits some positive signals of efficacy. Efficacy is measured through parameters such as foaming, residue rates, and removal of soils from surfaces. The composition comprising a blend of amphoteric and nonionic surfactants exhibits lower foaming, very low residue rates, acceptable degreasing performance, and prevention of redeposition of soils onto the surface after cleaning.

[0064] Although fragrance is highly volatile, volatility is the key to realizing the function of fragrance in practical applications. Different strategies have been utilized to boost fragrance performance, the majority of which concentrate on regulating this volatility. The present invention, however, utilizes fragrance boosters that can be added to fragrance systems while meeting the following requirements: (1) the fragrance booster enables sustained release of the fragrance, the duration of which is designed according to the specific application; (2) the fragrance released from the fragrance booster is controllable; (3) the fragrance booster does not affect the smell of the fragrance; (4) the fragrance booster is chemically inert against the material component in the application; (5) the fragrance booster is priced as affordably as possible.

[0065] In some implementations, the present cleaning composition further contains a fragrance booster. Suitable fragrance boosters include a polymer or a fixative.

[0066] Polymers

[0067] Polymers adsorb fragrance components into the surface to slow down their release and improve long lasting. Most polymers suitable as fragrance boosters are natural polymers, having a high affinity with many fragrances. This affinity is beneficial for the stabilization of fragrance molecules with the polymer. In addition, a wide variety of natural polymers exist, spanning different molecular weights and viscosities for use in the targeted applications. Furthermore, natural polymers are normally low-cost and environmentally friendly.

[0068] Examples of polymers suitable as fragrance boosters are xanthan gum, hydroxypropyl methyl cellulose (HMPC), pectin, cyclodextrin (derived from starch), shellac, cellulose, Polyquart® (1-Propanaminium, N,N,N-trimethyl-3-[(2-methyl-l-oxo-2-propen-l-yl)amino]-, chloride (1:1), polymer with ethyl 2-propenoate and sodium 2-propenoate (1:1), CAS No.192003-74-0, BASF Corporation), Magnafloc® (z.e., an anionic acrylamide copolymer) (BASF Corporation), sodium carboxymethylcellulose, and methacryl amido propyl trimethylammonium chloride, ethyl acrylate and acrylic acid polymer.

[0069] Fixatives

[0070] Fixatives have an affinity to fragrances and can reduce their volatility by reducing their vapor pressure. This slows down the evaporation of the volatile compounds, anchoring the fragrance to the surfaces. A wide variety of fixatives exist, spanning various volatilities, and can include solvents, resinoids, and animal origin fixatives. Other fixatives are not odorless and add complexity to the fragrance, exalting their own notes on the fragrances.

[0071] Still other fixatives are materials with superior boiling points that increase the boiling point of the fragrance composition. These fixatives are odorless and viscous and can include substances that are more ecological, economic and profitable such as dipropylene glycol, cyclopentadecanolide, benzyl salicylate, triethyl citrate, glycerin, caprylyl glycol and 1,3-propanediol. Examples of non-volatile substances are molecules with high molecular structure, such as benzoin or musk.

[0072] The amount of fragrance booster that may be used in the cleaning compositions of the present disclosure range from about 0.001% to about 10%, from about 0.001% to about 5% by weight, about 0.001% to about 1%, about 0.02% to about 0.75%, about 0.05% to about 0.70%, about 0.1% to about 1%, about 0.15% to about 0.8%, about 0.25% to about 0.75%, about 0.37% to about 0.65%, about 0.37% to about 0.5%, about 0.5%, or about 0.15% by weight of the cleaning composition.Methods

[0073] The present disclosure is also directed to a method of preparing a cleaning composition with enhanced fragrance performance. In some implementations, the method includes combining at least one amphoteric surfactant and at least one nonionic surfactant, to form a mixture. The amounts and ratios of the amphoteric and nonionic surfactants used in the present methods are thesame as previously described herein. Typically, less than about 1% by weight of a combination of CAPB, EO, and APG is included in the mixture using a ratio of amphoteric surfactant to nonionic surfactant of about 1:1. In some implementations, a fragrance system is added to the mixture. Typically, the fragrance system is present in the cleaning composition in an amount as described above. In some implementations, at least one fragrance booster is added to the mixture. Typically, the fragrance booster is present in the composition in an amount as described above. In some implementations, a fragrance system and at least one fragrance booster are added to the mixture. In various implementations, water and additional ingredients such as buffers, preservatives and coloring agents of the types and amounts described herein are also added to the mixture.

[0074] In other implementations, the cleaning compositions disclosed herein can be used to clean substrates by applying the composition to a substrate and optionally wiping the substrate. In certain implementations, the cleaning composition is formulated to be a bucket dilutable cleaner.EXAMPLESExample 1 - Fragrance Boosters

The same amount and type of fragrance is used in all three compositions. The fragrance performance of each of the exemplary cleaning compositions is evaluated and compared with the corresponding comparative cleaning composition that contains the same fragrance and amount of fragrance.

[0077] The fragrance intensity of each of the comparative and exemplary cleaning compositions is evaluated initially and over time in order to assess the fragrance performance of each of the cleaning compositions. Several cleaning cloths are treated using 2g of a 2.5% prototype solution of the comparative and exemplary cleaning compositions R, G, and H, respectively. Three sets of cleaning cloths are prepared and then enclosed in 4L glass jars with perforated lids, which are protected with adhesive and stored in an incubator until measurements are taken using Cyranose® 320 (Sensigent Intelligent Sensing Solutions, of Baldwin Park, California). The Cyranose® 320 is a fully-integrated handheld chemical vapor sensing instrument designed specifically to detect and identify aromas, odors, fragrances, formulations, spills and leaks. Fragrance evaluation is taken at the same touch points, at 0 hours, 2 hours, 6 hours, and 24 hours after initial application.

[0078] As is evident from FIG. 1, the intensity of fragrance evaluated over time (hours 0, 2, 6, and 24) is increased with the addition of HPMC (sample H) or glycerin (sample G) in comparison with the control (sample R). Figure 1 depicts normalized data of the results of intensity over time (Oh, 2h, 6h, 24h) for glycerin and hydroxypropyl methylcellulose. As can be seen from the data inFigure 1, each of HPMC and glycerin surprisingly and unexpectedly increases the fragrance intensity over comparative example R at times 2h, 6h, and 24h.Example 3 - Surfactant Evaluation

[0079] Comparative cleaning compositions (labeled Cl, C2, C3 and C4) with varying wt / wt ratios of anionic to nonionic surfactant but with no amphoteric surfactant are prepared and evaluated. The formulations of comparative cleaning compositions, C1-C4 are shown in Table 2, below, with values expressed as weight percent of the total composition (i.e., wt / wt %). Exemplary cleaning compositions (labeled El, E2, E3 E4, E5, and E6) with varying wt / wt ratios of amphoteric surfactant and nonionic surfactant are prepared and evaluated. The formulations of exemplary cleaning compositions, E1-E6 are shown in Table 3, below, with values expressed as weight percent of the total composition (z.e., wt / wt %). The same amount and type of fragrance is used in all variations. The fragrance performance of each of the exemplary cleaning compositions is evaluated and compared with the comparative cleaning compositions.

[0082] The exemplary formulas containing amphoteric / nonionic surfactants combination are tested with consumers using either a low level of glycerin at 0.15% by weight of the composition or a higher level of glycerin at 0.5% by weight of the composition. Formulas comprising the higherlevel of glycerin are preferred in consumer tests, denoting other perceived benefits as a clear halo from the good fragrance experience.Example 4 - Turbidity Evaluation

[0083] The turbidity of sample C2 was too high to be measured. Bringing the total surfactant level to below 1% (Total Active Ingredients, “Al”) is challenging for the comparative cleaning compositions with either a neutral or acidic pH. Meanwhile, in Table 4 the samples of the exemplary cleaning compositions demonstrate superior emulsification, and do not present any challenges while adding the fragrance into the formulations.

[0084] Table 4 Turbidity ResultsCl C3 C4 E2 E3 E4 E6SLES / SLES / CAPB / EO CAPB / EO CAPB / EO CAPB / EO SLES / APGTotal Al APG APG / APG / APG / APG / APG 1.3%1.3% 1.04% 0.8% 0.7% 0.65% 0.55% FragranceEmulsificatio 3.2 6 6.5 3.55 3.77 2.2 2.12n (NTU)**NTU = Nephelometric Turbidity Unit

[0085] The formulations from Table 2 comprising an anionic / nonionic surfactant formula are turbid when formulated in an acidic base. (Higher NTU = more turbid.) Emulsification of the fragrance is difficult in these formulas. However, the formulas from Table 3 comprising an amphoteric / nonionic surfactant formula are clear and require low mixing power to completely incorporate the fragrance.Example 5 - Fragrance Release

[0086] The fragrance intensity of each of the comparative and exemplary cleaning compositions is evaluated initially and over time in order to assess the fragrance performance of each of the cleaning compositions. Several cleaning cloths are treated using 2g of a 2.5% prototype solution of the comparative and exemplary cleaning compositions from Tables 2 and 3. Three sets of cleaning cloths are prepared and then enclosed in 4L glass jars with perforated lids, which are protected with adhesive and stored in an incubator until measurements are taken using Cyranose® 320 (Sensigent Intelligent Sensing Solutions, of Baldwin Park, California). Fragrance evaluationis taken at the same touch points, both in neat and diluted forms, at 0 hours, 2 hours, 6 hours, and 24 hours after initial application.

[0087] To evaluate the BDC volatile compounds and compare between samples, the sum of the sensor responses is normalized and compared to the reference sample (Cl). After the normalization, a value > 1 denotes a superior performance as compared to the reference sample.

[0088] Comparative cleaning composition (labeled C5) with anionic and nonionic surfactant but with no amphoteric surfactant is prepared and evaluated. The formulations of comparative cleaning composition, C5 is shown in Table 5, below, with values expressed as weight percent of the total composition (z.e., wt / wt %). Exemplary cleaning compositions (labeled E7 and E8) with an acidic pH (E7) and a neutral pH (E8) are prepared and evaluated. The formulations of exemplary cleaning compositions, E7 and E8 are shown in Table 5, below, with values expressed as weight percent of the total composition (z.e., wt / wt %). The same amount and type of fragrance is used in all variations. The fragrance performance of each of the exemplary cleaning compositions is evaluated and compared with the comparative cleaning composition.

[0090] The fragrance intensity of each of the comparative and exemplary cleaning compositions is evaluated initially and over time in order to assess the fragrance performance of each of the cleaning compositions. Several cleaning cloths are treated using 2g of a 2.5% prototype solution of the comparative and exemplary cleaning compositions C5, E7, and E8, respectively. Three sets of cleaning cloths are prepared and then enclosed in 4L glass jars with perforated lids, which are protected with adhesive and stored in an incubator until measurements are taken using Cyranose® 320 (Sensigent Intelligent Sensing Solutions, of Baldwin Park, California). Fragrance evaluation is taken at the same touch points, both in neat and diluted forms, at 0 hours, 2 hours, 6 hours, and 24 hours after initial application.

[0092] As is evident from Figure 2, the intensity of fragrance evaluated over time (hours 2, 6, and 24) is increased for exemplary compositions E7 and E8 in comparison with the control (sample C5). Figure 2 depicts normalized data of the results of intensity over time (Oh, 2h, 6h, 24h) for samples E7 and E8, normalized to sample C5. Results over 1.0 demonstrate an increased fragrance intensity. As can be seen from the data in Figure 2, both the acidic (E7) and neutral (E8) exemplary formulations surprisingly and unexpectedly increase the fragrance intensity over comparative example C5 at times 2h, 6h, and 24h.

[0093] According to the experimental data reported by Cyranose® 320 Equipment, the exemplary formulas have a perceivable higher intensity 2 hours after application as compared to the C5 comparative example. This peak of higher intensity is perceivable even 24 hours after application.Example 6 - Degreasing

[0094] The degreasing effectiveness of the exemplary compositions is evaluated using an Abrasive Tester Equipment. The degreasing testing is performed on formica white tiles (20X30cm), which are soiled by using an aerographic gun and a blend of beef tallow (7.5%), hydrogenated tallow (2.5%), solvent 89.95% (Cyclohexane) and 0.05% colorant (approximately 1-2 grams). Thesolvent evaporates at room temperature for 30 minutes, leaving the surfactant and colorant behind (0.1 -0.2 grams).

[0095] An abrasive tester machine, ASTM D2486, is used to standardize the testing evaluation. The ASTM D2486 uses 300g weights and a wet sponge holding 2.5mL of the liquid cleaning composition dilution (2.5%) to perform 6 cleaning cycles at a speed of 5 cycles / minute. Measurements are taken with a colorimeter at three time points: before soiling, after soiling, and after cleaning with the composition. This experiment is performed for 7 repetitions to calculate a percentage of efficacy to determine if there is equal, inferior, or superior performance to remove grease.

[0096] As can be seen in Figure 3, surprisingly and unexpectedly, there is no statistically significant difference in the cleaning performance among the comparative and exemplary formulas tested. This is surprising as the exemplary formulas contain less total surfactant than the comparative formulas.

[0097] In an embodiment of the invention, the composition includes:1.1 a fragrance booster, a fragrance system, and a surfactant system comprising an amphoteric surfactant and a nonionic surfactant, wherein the surfactant system is present in an amount of less than about 1 wt.% by weight of the composition.1.2 Any of the preceding compositions, wherein the amphoteric surfactant is selected from the group consisting of alkylamidopropylamine N-oxide (APAO), alkyldimethylamine N-oxide (AO), alkylbetaine (Bt), alkylamidopropylbetaine (APB), cocamidopropyl betaine (CAPB), cocoamphoacetate and cocoamphodiacetate, and a combination thereof.1.3 Any of the preceding compositions, wherein the amphoteric surfactant comprises cocamidopropyl betaine (CAPB).1.4 Any of the preceding compositions, wherein the amphoteric surfactant is present in an amount of from greater than about 0% to less than about 0.45%, about 0.01% to about 0.44%, about 0.05% to about 0.40%, or about 0.25 wt.% by weight of the composition.1.5 Any of the preceding compositions, wherein the amphoteric surfactant is present in an amount of 0.25 wt.% by weight of the composition.1.6 Any of the preceding compositions, wherein the nonionic surfactant is selected from the group consisting of primary aliphatic alcohol ethoxylates, secondary aliphatic alcoholethoxylates, alkylphenol ethoxylates and ethyl ene-oxi de propylene oxide condensates on primary alkanols, and mixtures thereof.1.7 Any of the preceding compositions, wherein the nonionic surfactant comprises an ethoxylated alcohol, an alkyl polyglucoside, or a combination thereof.1.8 Any of the preceding compositions, wherein the nonionic surfactant comprises an ethoxylated alcohol and an alkyl polyglucoside.1.9 Any of the preceding compositions, wherein the ethoxylated alcohol comprises an ethoxylated alcohol with a linear C9-C11 alkyl carbon chain and an average of 7-12 EO mols.1.10 Any of the preceding compositions, wherein the nonionic surfactant is present in a total amount of about 0.1% to about 1.0%, about 0.1% to about 0.75%, about 0.1% to about 0.5%, about 0.1% to about 0.4%, about 0.1% to about 0.35%, about 0.1% to about 0.325%, about 0.1% to about 0.3%, about 0.1% to about 0.28%, about 0.1% to about 0.25%, or about 0.28% by weight of the composition.1.11 Any of the preceding compositions, wherein the ethoxylated alcohol is present in an amount of about 0.25 wt.% by weight of the composition.1.12 Any of the preceding compositions, wherein the alkyl polyglucoside is present in an amount of about 0.03 wt.% to about 0.17 wt.%, about 0.06 wt.% to about 0.13 wt.%, about 0.07 wt.% to to about 0.10 wt.%, or about 0.08 wt.% to about 0.09 wt.%, by weight of the composition, preferably, the alkyl polyglucoside is present in an amount of about 0.03 wt.% by weight of the composition.1.13 Any of the preceding compositions, wherein the weight ratio of EO to APG is about 10:1 to about 5:2, about 5:0.6 to about 5:1.7, about 5:1.2 to about 5:1.7, or about 5:1.3 to about 5:1.5, preferably, the weight ratio is about 5:0.6.1.14 Any of the preceding compositions, wherein the surfactant system comprises cocamidopropyl betaine, an ethoxylated alcohol, and an alkyl polyglucoside.1.15 Any of the preceding compositions, wherein the fragrance booster is a polymer selected from the group consisting of xanthan gum; hydroxypropyl methylcellulose; pectin; cyclodextrin; shellac; cellulose; acrylic copolymer, sodium salt; an anionic acrylamide copolymer; and sodium carboxymethylcellulose.1.16 Any of the preceding compositions, wherein the fragrance booster is a fixative selected from the group consisting of propylene glycol, cyclopentadecanolide, benzyl salicylate, triethyl citrate, glycerin, caprylyl glycol, and 1, 3-propanediol.1.17 Any of the preceding compositions, wherein the fragrance booster is glycerin; wherein the glycerin is present in an amount of about 0.15 wt.% to about 0.5 wt.%, preferably about 0.5 wt.% of the composition.1.18 Any of the preceding compositions, wherein the fragrance system is present in the cleaning composition in an amount of about 0.37% to about 0.65% by weight of the composition, preferably in an amount of 0.37% by weight of the composition.1.19 Any of the preceding compositions, further comprising a preservative system comprising lactic acid, citric acid, or a combination thereof; wherein the preservative system is present in an amount of about 0.05% to about 0.5% by weight of the composition.1.20 Any of the preceding compositions, wherein the preservative system comprises less than 0.05% glutaraldehyde (GDA), optionally, is free of GDA.
