Definitions

  • This invention relates to liquid detergent compositions for use in cleaning hard surfaces, particularly bathroom surfaces.
  • Such compositions typically contain detergent surfactants, solvents, builders, etc.
  • liquid detergent compositions comprise organic cleaning solvents, detergent surfactants, and optional detergent builders and/or abrasives.
  • Liquid cleaning compositions have the great advantage that they can be applied to hard surfaces in neat or concentrated form so that a relatively high level of, e.g., surfactant material and/or organic solvent is delivered directly to the soil. Therefore, liquid cleaning compositions have the potential to provide superior soap scum, grease, and oily soil removal as compared to dilute wash solutions, e.g., those prepared from powdered cleaning compositions.
  • the present invention provides aqueous acidic hard surface cleaning compositions suitable for removal of soils commonly encountered in the bathroom, said compositions having specific mixtures of surfactants, solvents, and organic acids. These acidic hard surface cleaning compositions remove soap scum and hard water marks.
  • the compositions can have disinfectant properties achieved through the choice of actives, including citric acid and cationic surfactants, and can be used with or without additives such as hydrogen peroxide for additional mold/mildew prevention benefits. Further, the compositions can advantageously incorporate one or more hydrophilic polymers for improved surface wetting and filming/streaking properties.
  • the hard surface detergent cleaning compositions herein comprise: a. from about 0.5% to about 5% alkyl aryl sulfonate detergent surfactant; b. from about 1% to about 8% of hydrophobic cleaning solvent selected from the group consisting of: di-propylene glycol mono-butyl ether; tri- propylene glycol mono-butyl ether; ethylene glycol mono-hexyl ether; and mixtures thereof; c.
  • an anionic cosurfactant selected from the group consisting of: C 8 -C 18 linear or branched alkyl sulfates; C 8 -C 18 alkyl ethoxy sulfates; and mixtures thereof; d. optionally, from about 0% to about 2% nonionic alcohol and/ or cationic surfactant; e. from about 2 % to about 8 % of water soluble polycarboxylic acid; f. optionally, an effective amount, up to about 5%, of hydrogen peroxide; g.
  • a hydrophilic polymer selected from the group consisting of: xanthan gum; polystyrene sulfonate; polyvinyl pyrrolidone; polyvinyl pyrrolidone acrylic acid copolymer; polyvinyl pyridine; polyvinyl pyridine n-oxide; and mixtures thereof; and g. the balance an aqueous solvent system, and wherein the cleaning compositions are predominantly in micellar phase with a composition pH of from about 2 to about 4. It is believed that the improved cleaning is a direct result of the selection of the specific surfactants, solvent and polycarboxylic acids.
  • compositions of the invention are especially useful for cleaning soils that are commonly encountered in the bathroom. These include dust particles, hard water stains, fatty acids, triglycerides, lipids, insoluble fatty acid soaps, and the like.
  • the detergent compositions can be used on many different surface types, such as ceramic, fiber glass, polyurethane, and plastic surfaces.
  • Alkyl aryl sulfonates are an essential component of the invention. Due to their ubiquitous nature, such surfactants provide considerable cost advantages versus other anionic surfactants. Suitable alkyl aryl sulfonates can be neutralized with any alkali metal such as lithium, sodium, potassium and the like, or can alternatively be neutralized with an ammonium or C1 -C9 ammonium salt derivative such as mono- ethanol amine, diethylamine, tri-isopropanol amine and the like. They can be produced via any suitable process, leading to the formation of either "low 2-phenyl” or "high 2-phenyl” derivatives, though the "low 2-phenyl” derivatives are generally preferred.
  • Such surfactants are commercially available from several suppliers globally, including Witco Corporation (One American Lane, Greenwich, Connecticut 06831), Stepan Company (Edens & Witnetka Rd, Northfield, Illinois 60093) and BASF Aktiengesellschaft (ESA/1550, D-67056 Ludwigshafen, Germany).

It has been found that low levels of surfactant can also be advantageous to overall cleaning performance. Thus, at levels of alkyl aryl sulfonate higher than about 5%, hard water mark removal is observed to deteriorate. While not wishing to be limited by theory, it is believed that high levels of surfactant compete for surface sites with the polycarboxylic acid required in the present invention, thus inhibiting the action of the organic acid.

  • the hydrophobic cleaning solvent also can participate in the building of viscosity, if needed, and in increasing the stability of the composition.

Sweede Road, Midland, Michigan) under the trade names Arcosolv® and Dowanol®.

  • the perfumes are preferably those that are more water-soluble and/or volatile to minimize spotting and filming.
  • the perfumes useful herein are described in more detail in U.S. Patent 5,108,660, Michael, issued April 28, 1992, at col. 8 lines 48 to 68, and col. 9 lines 1 to 68, and col. 10 lines 1 to 24, said patent, and especially said specific portion, being incorporated by reference.
  • Perfume components can be natural products such as essential oils, absolutes, resinoids, resins, concretes, etc., and/or synthetic perfume components such as hydrocarbons, alcohols, aldehydes, ketones, ethers, acids, acetals, ketals, nitriles, etc., including saturated and unsaturated compounds, aliphatic, carbocyclic and heterocyclic compounds.
  • perfume components are: geraniol, geranyl acetate, linalool, linalyl acetate, tetrahydrolinalool, citronellol, citronellyl acetate, dihydromyrcenol, dihydromyrcenyl acetate,, terpineol, terpinyl acetate, acetate, 2-phenylethanol, 2-phenylethyl acetate, benzyl alcohol, benzyl acetate, benzyl salicylate, benzyl benzoate, styrallyl acetate, amyl salicylate, dimenthylbenzylcarbinol, trichloromethylphenycarbinyl acetate, p-tert.butyl- cyclohexyl acetate, isononyl acetate, alpha-n-amylcinamrnic aldehyde, alpha-hexyl- cina
  • compositions herein typically comprise from 0J%> to 2% by weight of the total composition of a perfume ingredient, or mixtures thereof, preferably from 0J%> to 1.0%.
  • the perfumes must be chosen so as to be compatible with the oxidant.
  • the perfume ingredients are hydrophobic and highly volatile, e.g., ingredients having a boiling point of less than about 260°C, preferably less than about 255°C; and more preferably less than about 250°C, and a ClogP of at least about 3, preferably more than about 3J, and even more preferably more than about 3J.
  • the logP of many ingredients has been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, California, contains many, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP” program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database.
  • the "calculated logP” (ClogP) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p.
  • the fragment approach is based on the chemical structure of each ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding.
  • the ClogP values which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental logP values in the selection of the principal solvent ingredients which are useful in the present invention.
  • Other methods that can be used to compute ClogP include, e.g., Crippen's fragmentation method as disclosed in J. Chem. Inf. Comput. Sci., 27, 21 (1987); Viswanadhan's fragmentation method as disclose in j. Chem. Inf. Comput. Sci., 29, 163 (1989); and Broto's method as disclosed in Eur. j. Med. Chem. - Chim. Theor., 19, 71 (1984).
  • compositions herein can comprise a variety of other optional ingredients, including further actives and detergent builder, as well as mere aesthetical ingredients.
  • further actives and detergent builder as well as mere aesthetical ingredients.
  • rheology of the compositions herein would be suitable for suspending particles in the composition, e.g., particles of abrasives.
  • Detergent builders that are efficient for hard surface cleaners and have reduced filming/streaking characteristics at the critical levels are another optional ingredient.
  • Preferred detergent builders are the carboxylic acid detergent builders described hereinbefore as part of the polycarboxylic acid disclosure, including citric and tartaric acids. Tartaric acid improves cleaning and can minimize the problem of filming/streaking that usually occurs when detergent builders are added to hard surface cleaners.
  • the detergent builder is present at levels that provide detergent building, and, those that are not part of the acid pH adjustment described hereinbefore, are typically present at a level of from about 0J%> to about 0.3%. more preferably from about 0.2%) to about 2%, and most preferably from about 0.5 to about 1%>.
  • compositions herein can also contain other various adjuncts which are known to the art for detergent compositions. Preferably they are not used at levels that cause unacceptable filming/streaking.
  • Non-limiting examples of other adjuncts are: enzymes such as proteases; hydrotropes such as sodium toluene sulfonate, sodium cumene sulfonate and potassium xylene sulfonate; thickeners at a level of from about 0.01 %> to about 0.5%, preferably from about 0.05%> to about 0.4%; and aesthetic-enhancing ingredients such as colorants, providing they do not adversely impact on filming/streaking.
  • enzymes such as proteases
  • hydrotropes such as sodium toluene sulfonate, sodium cumene sulfonate and potassium xylene sulfonate
  • thickeners at a level of from about 0.01 %> to about 0.5%, preferably from about 0.05%> to about 0.4%
  • aesthetic-enhancing ingredients such as colorants, providing they do not adversely impact on filming/streaking.
  • Antibacterial agents in addition to the cationic ones described hereinbefore, can be present, but preferably only at levels below about 0.5%, preferably below about 0.4%), to avoid filming/streaking problems. More hydrophobic antibacterial/germicidal agents, like orthobenzyl-para-chlorophenol, are avoided. If present, such materials should be kept at levels below about 0.1%.
  • composition making:
  • compositions herein can be made by mixing together all ingredients.
  • a preferred order of addition is to first incorporate water, alkyl aryl sulfonate surfactant and organic acid, followed the hydrophobic cleaning solvent. Once the solvent is added, pH is adjusted to optimum as desired by the formulator.
  • Optional cationic surfactant, peroxide, polymer, perfume and dye can then be added.
  • Soap Scum Cleaning Standard soiled plates that are used to provide a reproducible, standard soiled surface are treated with each product and the surface is then wiped with a sponge using a Gardner Straight line Washability Machine. The number of strokes required for complete cleaning is measured and recorded.
  • the soap scum cleaning index is calculated using the following equation: (# strokes for control product/# strokes for experimental product) * 100, where the control product is Dow Bath Room ® aerosol and the experimental prototypes are compositions 1-8 disclosed herein. Indices greater than 100 are suggestive of products with superior soap scum removal properties.
  • Hard Water Cleaning Four marble chips for each product tested of approximate dimensions 3 / 4 " x 3 /" x %" are weighed to four decimal places using an analytical balance.
  • the chips are then placed in 100 ml beakers containing 20 grams of product for a total of 10 minutes.
  • the marble chips are then removed, rinsed and allowed to dry. They are then re-weighed and the weight lost is computed. Using averages of four trials for each product, the hard water removal index is computed as follows: (average weight loss of the marble chips immersed in the control product/ average weight loss of the marble chips immersed in the experimental compositions) * 100.
  • Soap scum removal and hard water removal test comparisons are made versus a commercially available product Dow Bath Room ® aerosol.
  • compositions are made by mixing the listed ingredients in the listed proportions in the listed order of addition.
