Definitions
- the present invention concerns compositions which can be useful in particular in fabric softening applications and a process for the preparation thereof.
- the present invention relates to alkoxylated ester-amine fabric softening compositions, the protonated or quatemized forms thereof, and processes for the preparation of the same.
- compositions suitable for providing fabric softening and static control benefits during laundering are well known and have found wide commercial application.
- rinse-added fabric softening compositions contain as the active softening component, substantially water-insoluble cationic materials having more than one long alkyl chain. Typical of such cationic materials are ditallow dimethyl ammonium chloride and immidazolinium compounds substituted with two stearyl groups. These materials are normally prepared in the form of a dispersion in water.
- esterquats are also used as cationic fabric softening agents. See, for example, International Patent Application Publication No. WO 93/25648, German Patent No. 4,339,643 and U.S. Patent Nos. 4,339,391 ; 4,767,547, 4,874,554 and 5,066.414.
- European Patent Application No. 0'638'639 A1 teaches various reverse esterquats which are said to be good fabric softening compositions having improved hydrolytic stability and biodegradability.
- alkoxylated ester-amines of Formula I and their protonated and quatemized forms of Formulae II and III, respectively are not only good softeners but are also hydrolytically stable and, thus, they can be used to formulate stable softener formulations. Since the alkoxylated ester-amines of the present invention are often low viscous liquids at room temperature, they can be advantageously mixed with water and acids at room temperature.
- alkoxylated esterquats prepared by first esterifying an alkoxylated alkanolamine and then quaternizing, so obtained alkoxylated ester-amine with a suitable quatemizing agent, have been suggested as fabric softening agents. See, for example, International Patent Application Publication No. WO 91/01295, German Patent Nos.
- an alkanolamine is first alkoxylated, followed by the esterification and quatemization of the respectively produced compounds.
- an alkanolamine is first esterified, followed by the alkoxylation of the resulting ester-amine and, if desired, quatemization of the resulting alkoxylated ester-amine.
- the alkoxylated ester-amine produced by the respective processes are also clearly different chemical entities.
- softening compositions of the present invention exhibit-high hydrolytic stability over a wide pH range, have low melting points, are compatible with detergent and personal care ingredients and they can be handled either in the diluted form or formulated as stable liquid concentrates.
- composition embraces both a single chemical entity and a mixture of chemical entities having the same general formula.
- hydrolytically stable means that less than 30 percent, preferably less than 20 percent, of a composition of Formula (III) below and less than 40 percent of a composition of Formula (I) or (II) below hydrolyzes after 4 weeks from a 5 percent aqueous solution having a pH value of 4. It should be understood that the extent of hydrolysis defined above is valid for a value of pH 4 and that hydrolysis extent would decrease with decreasing pH and increase with increasing pH.

- the esterification reaction is carried out until the residual content of said fatty acid is less than 30 percent by weight of the total weight of the reaction mixture • and so that 5 to 90 percent of the available OH groups remain unreacted; and
- step (b) alkoxylating at least a portion of the ester amine compound obtained in step (a) with a C 2 - C 6 alkylene oxide such as, for example, ethylene oxide, propylene oxide and butylene oxide or mixtures of such oxides (block or random) in the presence of an alkaline catalyst such as sodium, potassium, calcium, barium and strontium hydroxide, in an amount of from 0.01 to 5, preferably 0.1 to 0.5, percent by weight based on the total weight of the mixture at the completion of the reaction.

- the alkaline catalysts suitable for use in this reaction are well known to a person skilled in the art.
- the catalyst is removed by a suitable method, such as by filtration over an absorbing clay, for example, magnesium silicate, or neutralized with an inorganic acid such as, for example, hydrochloric acid, or an organic acid such as, for example, acetic acid.

- Any known inorganic acid such as, for example, hydrochloric acid, or organic acid such as, for example, citric acid can be used as the HA compound to protonate the alkoxylated ester-amine (see for example, International Published Patent Application Nos. WO 94/04641 and WO 94/04642).
- the protonation reaction is suitably carried out at room temperature or above melting point of the alkoxylated ester-amine compound.
- Any known quaternizing agent can be used as the QA compound.
- Suitable quaternizing agents of formula QA include alkyl halides, dialkyl sulfates, and trialkyl phosphates.

- the quatemization reaction is suitably carried out at a temperature of from 30°C to 150°C, and a pressure of from 1 to 50 bars. It is advantageous to carry out the quatemization reaction in the presence of a defoaming agent.
- compositions of Formulae I, II and III of the present invention exhibit good softening, antifoaming and antistatic properties, they have low melting points, are hydrolytically stable at various pH values. Moreover, they are compatible even with fabric and paper softeners' ingredients and detergents ingredients which are normally not compatible with known softening compounds without the presence of special additives. Due to these properties the composition mixtures of Formulae I, II and III of the present invention can be formulated into formulations suitable for various end use applications such as, for example, fabric and paper softening formulations, formulation for cleaning and conditioning fabric materials ("softergents"), antifoaming formulations, personal care formulations, lubricating formulations, drilling fluid formulations and hard surface cleaning formulations.
- softergents formulation for cleaning and conditioning fabric materials
- antifoaming formulations personal care formulations
- lubricating formulations drilling fluid formulations and hard surface cleaning formulations.
- the present invention concerns a fabric or paper softening formulation comprising at least one composition of Formulae I, II and III above or a mixture thereof and, optionally, at least one known softening compound.
- the fabric and paper softening formulations of the present invention can also incorporate one or more known ingredients commonly used in fabric or paper softening formulations.
- the fabric and paper softening formulations of the present invention can be in various forms, such as, for example, aqueous or anhydrous liquid formulations, super concentrate liquid formulations, solid formulations obtained by a suitable process such as grinding the softener composition or depositing it onto solid substrates such as powders or granules, or onto cellulosic substrate sheets for use in tumble dryers.
- the fabric softening formulations can be used in a tumbler dryer or in the rinse cycle in a washing machine for example by dispensing the fabric softening formulation via a dispensing compartment optionally with dilution prior to dosing into the dispensing compartment.
- the fabric and paper softening formulations of the present invention which have a pH below 8 when diluted for normal use conditions are preferred.
- the present invention concerns an anhydrous or aqueous fabric and paper softening formulation comprising at least 0.01 , preferably from 0.01 to 95 percent by weight of at least one composition of the above general Formulae I, II and III.
- the liquid fabric and paper softening formulations of the present invention may be prepared by mixing at least one softening composition of Formulae I, II and III above with a liquid carrier and, optionally, at least one other above mentioned ingredient in a standard formulation mixing equipment and in accordance with techniques known to a person skilled in the art. Low-shear mixing is generally sufficient to adequately and uniformly mix the softening composition within the softening formulation.
- the final softening formulation, whether in concentrated or diluted form must be easily pourable by the end user.
- the formulation may be formulated to be diluted (for example, for refill packs) by a factor of generally 4:1 or more, preferably up to 8:1 or even up to 20:1.
- compositions of the present invention of Formulae I, II and III have unexpectedly higher hydrolytic stability than known softening agents, but they also have lower melting points than known softening agents. Without the desire to be bound to a theory, it is believed that this unique combination of high hydrolytic stability and low melting points of compositions of Formulae I, II and III above allow for the formulation of stable super-concentrated and, if desired, anhydrous fabric softening formulations with or without the incorporation of stabilizing additives. Even more surprisingly, it has been discovered that super concentrated and anhydrous fabric softening formulations incorporating at least one composition of Formulae I, II and III are transparent in most instances.
- the present invention also encompasses the super concentrated fabric softening formulations comprising from 10 to 100 percent of at least one composition of Formulae I, II and III.
- These super concentrated formulations can be used for example, for a refill pack (to be diluted in a large bottle) or as concentrates for direct use by a consumer, or can help save transportation costs of the softener or the fabric or paper softening formulations.
- softergents Mixtures of fabric softeners and detergents (softergents) are commercially available. Such formulations can be in liquid, paste or granular form. Such softergents normally contain soft clays and/or cationic surfactants having only one long alkyl group in the molecule (for example, lauryltrimethyl ammonium chloride).
- Known softergents have a number of limitations. For example, the softening performance of these softergents is inferior to the performance of a fabric softener used separately in the last rinse of the wash process.
- Another limitation is the difficulty in formulating softergents containing cationic softener having more than one long alkyl chain in the molecule (common softening agent used in softening formulations).
- Still another limitation is the fact that a cationic softener having one or more ester links must be formulated at a low pH which does not correspond to typical neutral to alkaline pH of the detergent.
- compositions of the present invention of Formulae I, II and III with conventional detergent ingredients and because they are hydrolytically stable at typical detergent pH's they can conveniently be formulated with any known detergent ingredients into a softergent having none of the aforementioned limitations.
- the present invention concerns a powder or liquid softergent formulation comprising 1 to 90 weight percent of at least one composition of Formulae I, II and III, which softergent formulation has a pH in the range of from 1.5 to 12.
- the absence of solvent in the composition of Formulae I, II and III above makes the softergent safer to use.
- the composition of Formulae I, II and III above permits the selection of a softener which has low enough melting point to be suitable for making powder softergent and allows optimum dispersion during the wash cycle.
- the present invention concerns defoaming or antifoaming aqueous formulations comprising at least one composition of Formulae I, II or III above.
- the defoaming and antifoaming aqueous formu'ations of the present invention are suitable for use in applications such as sugar beet washing, and dish washing, at a pH range of from 1.5 to 12, although due to their improved hydrolytic stability they are particularly suitable for use in the mid-alkaline pH range.
- compositions of the present invention of Formulae I, II and III above can suitably be formulated with a wide variety of known materials commonly found in fabric or paper softening formulations, laundry detergents, hard surface cleaning formulations and personal care formulations.
- materials used in fabric or paper softening formulations, laundry detergents, hard surface cleaning formulations and personal care formulations include, but are not limited to the following:
- Enzymes and Enzyme Stabilizers - Enzymes can be included for various fabric cleaning and fabric softening purposes.
- suitable enzymes include proteases, amylases, lipases, cellulases, and peroxidases, as well as mixtures thereof.
- the enzymes may be of any suitable origin, such as vegetable, animal, bactericidal, fungal and yeast origin.
- the enzymes used may be stabilized by the presence of water- soluble sources of calcium and/or magnesium ions in the finished compositions which provide such ions. Any water-soluble calcium or magnesium salt can be used as a source of calcium or magnesium ions.
- a wide range of useful enzyme and enzyme stabilizer materials are described in International Patent Application Publication Nos. WO 95/19951 and WO 96/21715, and European Patent Application Nos. 0'579'295 A1 and 0'583'536 A1.
- Bleaching Agents and Bleach Activators Any known bleaching agent used in fabric or paper treatment applications can be used.
- suitable bleaching agents include oxygenated bleaches, percarboxylic acid bleaches, peroxygen bleaches and mixtures thereof.
- Bleach activator can also be used.
- Various nonlimiting examples of useful bleaching agents and bleach activators are given in International Patent Application Publication No. WO 95/19951.
- Buiiders - Inorganic and organic builders commonly used in fabric laundering formulations to assist in removal of particulate solids can be used.
- Suitable builders include, but are not limited to, phosphates, polyphosphates, silicates, aluminosilicates, phosphonates, carboxylates, zeolites and succinates.
- Nonlimiting examples of suitable builders are described in International Patent Application Publication No. WO 95/19951 and European Patent Application No. 0'579'295 A1 , and European Patent Application No. 0'580'245 A2.
- Soil Release Agents Any known polymeric soil release agent used in laundry cleaning formulations can be used.
- Polymeric soil release agents include, but are not limited to, the compounds having: (i) at least one nonionic hydrophilic component consisting essentially of (a) polyoxyethylene segments with a degree of polymerization of at least 2, or (b) oxypropylene or polyoxypropylene segments with a degree of polymerization of from 2 to 10, or (c) a mixture of oxyalkylene units comprising oxyethylene and from 1 to 30 oxypropylene units, (d) cellulosic derivatives such as hydroxyether cellulosic polymers, (e) copolymeric blocks of terephthalate with polyethylene oxide or polypropylene oxide.
- Nonlimiting examples of useful soil release agents are given in International Patent Application Publication No. WO 95/04802, WO 93/23510 and WO 93/25648.
- Chelating agents Any known chelating agent is suitable for use. Suitable 5 chelating agents include, but are not limited to, amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures thereof. It is believed that the benefit of the chelating materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates.
