Definitions

  • the present invention relates to cleaning formulations comprising water, one or more organic solvents having low solubility in water such as aliphatic hydrocarbons, aromatic hydrocarbons, or other organic compounds, and an alkylene glycol dilevulinate.
  • the alkylene glycol dilevulinates are excellent solvents for coupling the organic solvents with water.
  • Organic solvents are compounds that can be used to dissolve, soften, melt, or extract another compound, such as grease, soil, oil, paint, glue, stains, etc., and, therefore, are commonly used in cleaning formulations.
  • Typical organic solvents include aliphatic hydrocarbons, isoparaffins, aromatic hydrocarbons, chlorinated hydrocarbons, terpenes and d-limonene, among others.
  • Unfortunately, many organic solvents have limited solubility, or practically zero solubility, in water which severely limits the amounts that can be added to water-based cleaning formulations sometimes to the point where their beneficial effects cannot be realized.
  • Coupling agents are compounds that facilitate dissolution and dispersion of organic solvents, into water-based formulations, in greater amounts than otherwise possible, while the formulations retain their clarity, viscosity and homogeneity.
  • Various coupling agents are known for use in cleaning formulations including propylene glycol, diethylene glycol, glycol ethers, and surfactants, among others. See U.S. Patent Nos. 4,511,488 .
  • lower glycol ethers are volatile organic compounds (VOCs) which are environmentally undesirable.
  • VOCs volatile organic compounds
  • Some higher glycol ethers have lesser solubility in water-based systems, which limits their utility as coupling agents.
  • WO 2010/138907 discloses a solution comprises a solute dissolved in an aqueous cosolvent mixture, where the aqueous cosolvent is a mixture that includes water and at least one alkyl ketal ester that is miscible in water at the relative proportions of it present in the cosolvent mixture.
  • the preferred alkyl ketal esters are based upon levulinic acid. Esters of levulinic acid are well known and described in the art as plasticizers and solvents. For example, GB423919 describes the production of esters of levulinic acid with modified polyhydric alcohols which are useful as plasticizers for cellulose derivatives in coating applications.
  • U.S. Patent No. 2,654,723 describes the preparation of diethylene glycol dilevulinate by heating a mixture of levulinic acid and diethylene glycol, in a solvent such as toluene and in the presence of an acid catalyst.
  • WO 2010/102203 describes the preparation of alkyl levulinates by an acid-catalyzed reaction of furfuryl alcohol with other alcohols including methanol, ethanol, propanol, isopropanol, butanol, and isobutanol.
  • U.S. Patent No. 3,203,964 a process is described for manufacturing levulinic acid esters by heating furfuryl alcohol with another alcohol selected from the group consisting of unsubstituted primary and secondary carbon chain and oxygen-carbon chain aliphatic and carbon ring and oxygen-carbon ring cycloaliphatic alcohols containing from 1 to 10 carbon atoms, in the presence of a an acid catalyst.
  • U.S. Patent No. 3,203,964 states that the levulinic acid esters are useful as plasticizers or solvents.
  • GB478854 describes the use of lower alkylene glycol dilevulinates (e.g., dilevulinates of propylene glycol, diethylene glycol, ethylene glycol, trimethylene glycol (1,3-propanediol), 1,3-butylene glycol and dimethyl-dimethylol) as suitable high boiling softening agents for cellulosic pellicles.
  • U.S. Patent No. 2,581,008 discloses the preparation of dilevulinates of mono-, di- and tri-ethoxylated diols and their use as plasticizers for polyvinyl acetals and other polymers.
  • Furfuryl alcohol and levulinic acid are two of the reactants that can be used to manufacture esters of levulinic acid, e.g., alkylene glycol dilevulinates. They are both inexpensive renewable feedstocks available from biomass. Thus, the use of levulinates as solvents in water-based cleaning formulations would be economically and environmentally beneficial.
  • the present invention provides for the use of alkylene glycol dilevulinates as new alternative coupling agent solvents in water-based formulations.
  • the present invention provides a cleaning formulation comprising: (A) an aqueous solvent comprising water; (B) an active component comprising an organic solvent; and (C) a coupling agent comprising an alkylene glycol dilevulinate.
  • the alkylene glycol dilevulinate has the general formula, CH 3 C(O)CH 2 CH 2 C(O)O-R-O(O)CCH 2 CH 2 C(O)CH 3 , wherein R is a C 2 -C 8 straight chain or branched alkylene moiety, and the two levulinate groups (CH 3 C(O)CH 2 CH 2 C(O)O-) may be attached to adjacent, or non-adjacent, carbon atoms of the alkylene moiety.
  • R may be a C 2 -C 3 alkylene moiety
  • the alkylene glycol dilevulinate may be selected from the group consisting of: ethylene glycol dilevulinate, 1,2-propylene glycol dilevulinate and 1,3-propylene glycol dilevulinate.
  • the organic solvent may have a solubility of no more than 10%, or no more than 5%, by weight, in water at 25oC and atmospheric pressure, based on the total weight of the organic solvent and water in solution.
  • the organic solvent may be at least one compound selected from the group consisting of: an aliphatic hydrocarbon, an aromatic hydrocarbon, a chlorinated hydrocarbon, a terpene, lemon oil, pine oil, methyl soyate and d-limonene.
  • the aqueous solvent comprising water (A) may be present in an amount of from 90% to 98% by weight
  • the active component comprising an organic solvent (B) may be present in an amount of from 0.1% to 5.0% by weight
  • the coupling agent comprising an alkylene glycol dilevulinate (C) may be present in an amount of from 0.1% to 6.0%, all weight percentages based on the total weight of the cleaning formulation.
  • the present invention relates to the use of alkylene glycol dilevulinates or mixtures of alkylene glycol dilevulinates in water-based cleaning formulations to couple active components comprising organic compounds such as solvents or fragrances, having low or zero water solubility, with water.
  • Alkylene glycol dilevulinates can be economically produced from levulinic acid and a glycol.
  • Levulinic acid is available from biomass and is, therefore, a renewable environmentally-friendly resource.
  • glycols such as 1,2-propylene glycol and 1,3-propylene glycol are biorenewable and, therefore, also environmentally-friendly materials.
  • Alkylene glycol dilevulinates are high boiling, clear liquids with minimal odor and are not volatile organic compounds (VOCs). These particular characteristics provide benefits and advantages to their use as alternative coupling agents in water-based cleaning formulations. For example, traditional coupling agents such as propylene glycol, diethylene glycol and lower glycol ethers are volatile organic compounds (VOCs) which are environmentally undesirable. Also, with the exception of dipropylene glycol methyl ether, glycol ethers are not as effective couplers as the alkylene glycol dilevulinates. The alkylene glycol dilevulinates are partially to completely water soluble and are not VOCs.
  • VOCs volatile organic compounds
  • alkylene glycol dilevulinates are water soluble and, therefore, useful as coupling agents in water-based systems is a surprising and unexpected benefit. Furthermore, applicants have discovered that alkylene glycol dilevulinates provide better coupling performance which allows the use of greater amounts of organic solvents having low or zero water solubility with water, than when traditional coupling agents are used. Inclusion of greater amounts of the organic solvents increases cleaning efficiency while maintaining preferred formulation characteristics such as homogeneity, clarity, stability and viscosity.
  • alkylene glycol dilevulinates could be particularly useful in aerosol products such as hair care products, sanitizers, and insecticides, and spray applied consumer products.
  • These dilevulinate solvents allow the formulation of more efficient, safer and more environmentally friendly formulations and may facilitate the development of many novel formulations suitable for cleaning, coatings, pigment dispersants, pesticides, and agricultural applications.
  • an alkylene glycol dilevulinate and “alkylene glycol dilevulinates” are both meant to include the presence of one or more compounds having the general formula, CH 3 C(O)CH 2 CH 2 C(O)O-R-O(O)CCH 2 CH 2 C(O)CH 3 , wherein R is a C 2 -C 8 straight chain or branched alkylene moiety, and the two levulinate groups (CH 3 C(O)CH 2 CH 2 C(O)O-) may be attached to adjacent, or non-adjacent, carbon atoms of the alkylene moiety.
  • an "alkylene glycol dilevuninate” may be one compound which satisfies the foregoing general formula, or a mixture of such compounds. Where a mixture of alkylene glycol dilevulinates is synthesized or otherwise available, it is not necessary that the various species from one another before using the mixture in a cleaning formulation in accordance with the present invention.
  • organic active components is meant to include organic materials that perform a particular function in the cleaning formulations, such as organic solvents, fragrances, etc.
  • Organic solvents as the term is used herein, means compounds that dissolve, soften, melt, or extract another compound, such as grease, soil, oil, paint, glue, stains, etc., and which are, therefore, commonly used in cleaning formulations.
  • Typical organic solvents include, without limitation, aliphatic hydrocarbons, isoparaffins, aromatic hydrocarbons, chlorinated hydrocarbons, and terpenes, among others.
  • fragrances means organic compounds that impart a particular odor to the cleaning formulation, and may or may not also provide the same function as organic solvents.
  • Typical fragrances include, for example, d-limonene, lemon oil and pine oil.
  • Coupled agents means compounds that facilitate dissolution and dispersion of organic solvents, into water-based formulations, in greater amounts than otherwise possible, while the formulations retain their preferred characteristics of clarity, viscosity and homogeneity.
  • Traditional coupling agents used in cleaning formulations include, without limitation, propylene glycol, diethylene glycol, glycol ethers, and some surfactants, among others.
  • endpoints of ranges are considered to be definite and are recognized to incorporate within their tolerance other values within the knowledge of persons of ordinary skill in the art, including, but not limited to, those which are insignificantly different from the respective endpoint as related to this invention (in other words, endpoints are to be construed to incorporate values "about” or “close” or “near” to each respective endpoint).
  • the range and ratio limits, recited herein, are combinable. For example, if ranges of 1-20 and 5-15 are recited for a particular parameter, it is understood that ranges of 1-5, 1-15, 5-20, or 15-20 are also contemplated and encompassed thereby.
  • the cleaning formulations of the present invention comprise an aqueous solvent comprising water, an active component comprising at least one organic solvent, and at least one alkylene glycol dilevulinate.

All three compounds also dissolve aromatic hydrocarbon compounds such as toluene and xylene, while having limited solubility for simple aliphatic hydrocarbons such as hexane and cyclohexane.

This information can be similarly translated to Columns 1 & 2 of Figures 10-12 & 14-16 .
  • 1,2-ethylene glycol dilevulinate 1,2-ethylene glycol dilevulinate
  • the sample formulation at Row F, Column 6 contained the standard ingredients listed in the TABLE above for Sets I & II, as well as 1.5% by weight d-limonene and 20% by weight 1,2-EGDL as the coupling agent, based on the total weight of the formulation.
  • Figures 10-12 & 14-16 show the results (clear/white or cloudy/black) for the sample formulations identified in the grids of Figures 9 & 13 at 5°C, room temperature (25°C), and 40°C, respectively. Clear indicates successful coupling of the d-limonene and cloudy indicates poor or no coupling.
  • Figures 1-16 showed the phase stability data of glycol ethers and alkylene glycol dilevulinates with varying levels of d-limonene in the presence of 1% SLS surfactant and absence (0% SLS) of surfactant.
  • Each formulation contained the following ingredients in the following amounts shown in the following TABLE OF STANDARD INGREDIENTS Examples A-FF: TABLE OF STANDARD INGREDIENTS - Examples A-FF Name Amount (wt %) Description/Comment VERSENE HEIDA 0.5 Chelating agent, commercially available from the Dow Chemical Company of Midland, Michigan, U.S.A.
  • An aqueous solution of disodium ethanoldiglycine which is readily biodegradeable. It is particularly useful for chelation of iron in mildly alkaline solutions Diisopropanolamine (DiPA) 0.50 A buffer, replaces traditional monoethanolamine (MEA) buffer Sodium Hydroxide (NaOH) 0.20 Buffer, pH adjuster Water variable Aqueous solvent
  • Each formulation contained a total of either 0.5% or 1.0% surfactants, as follows and indicated in TABLE 2 below:
  • NEODOL 25-7 a C 12 -C 15 alcohol mixture containing an average of 7 moles of ethylene oxide per mole of alcohol.
  • NEODOL 45-7 a C 14 -C 15 alcohol mixture containing an average of 7 moles of ethylene oxide per mole of alcohol.
  • Hard surface cleaning power of the formulations was tested by the removal of soil from a vinyl tile. Vinyl tiles were cut to match the sample size of 11.5 cm x 7.5 cm and 500 ⁇ L of 3% Carbon Black Brazil soil was applied to the grooved side of the tile using a foam applicator. The tiles were set to dry for approximately 24 hours, and then the tile was placed in the SCiD plate and set on the orbital shaker. 400 ⁇ L of the cleaning solutions were dispensed into each well along with one carpeted scrubbie, and the samples were run on the shaker for five minutes. For each sample, 3 wells were tested, and the samples were run side by side with a good and bad cleaning standard. The samples were scanned into the computer and analyzed by the ImageJ software.
  • the cleaning power was measured by the average gray value of the well, and the cleaning power of the sample was measured by the average of the gray value of the three wells.
  • a higher gray value corresponds to a lighter circle and a higher cleaning power, while a lower gray value corresponds to a darker circle and a lower cleaning power.
  • TABLE 2 presents the results of testing various formulations containing different coupling agents and surfactant combinations, using the aforesaid testing procedure. It is noted that values for filming and streaking each run from 1 to 10, with the lowest numbers representing the least filming or streaking and, therefore, being the preferred values. For the "average grey" performance characteristic, the higher values are considered more preferable.
