Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD This invention relates to compositions and methods for removing clay-based soils and stains from whole fabrics. The composition is particularly suitable for removing cosmetic stains consisting of a mixture of a clay-based material and an oily or greasy binder material. A composition is provided comprising a solvent component that disperses a binder and a polyamine material that disperses a clay.

These compositions are prepared using a simple fabric pressbotter (pr
A particularly pronounced 'Au benefit is against stains caused by cosmetics.

BACKGROUND Detergent formulators are tasked with engineering products that remove a broad spectrum of soils and stains from fabrics.

Chemically and physicochemically, dirt and stains,
The spectrum ranges from primarily oils, through tans and carbohydrates to inorganic, and detergent compositions vary as formulators seek to offer a full range of products that address all types simultaneously. It's getting more complicated.

For example, protease enzymes are commonly used in detergents for blood and meat stains. The amylase enzyme has been used for some time for carbohydrate staining. Nonionic fertility surfactants are
Used for hydrocarbon oils. And anionic surfactants and builders are used for particulate soils. Bleach is used to chemically degrade stains that are not easy to remove by less severe treatments.

One of the most difficult to remove from fabrics are cosmetic stains, and from time immemorial the stubborn stain of lipstick on a shirt collar or handkerchief is a nefarious deterioration of many. Furthermore, the remarkable ability of the modern cosmetics industry to provide products that last even longer on the user's skin has meant that today's cosmetics are not intentionally made more resistant to smearing on the fabrics on which they are applied. It definitely means.

Chemically, many cosmetics are made from clay bases (which partially serve as fillers, thickeners, carriers for color bodies, etc.) blended with oily substances that serve in part as binders, brighteners and emollients. Consisting of Cosmetics are typically made with oily substances that are in the form of very fine particles, and can be hydrocarbon oils, silicones, lipids or complex mixtures thereof. Care is taken to ensure thorough mixing and coating. Optimally from the cosmetic formulator's point of view, cosmetics contain 71 materials of very different stain types (oily, granular, clay) in intimate mixtures and often brightly coloured. Modern cosmetics create a huge problem for detergent formulators.
The detergent ingredients of - have such a complex L'l boundary
It is rationally impossible to take and absorb eu).

The present invention uses an oil removal solvent and a clay removal polyamine treatment. Solvents dissolve the oil bases of cosmetics, thereby dissolving their clay components. ! The polyamine material loosens and removes the clay components from the fabric.

The use of solvents of the type used in this invention as grease/oil removal components in each 45N cleaner
It is well known in commerce and from the patent literature. For example, U.S. Pat. No. 2,073,464-Dou, EPO

and the dry cleaning industry, hard surface [such as the well-known "degreasing" solvents commonly known for use in the fj cleaner industry and the metallurgy industry]. Typically, such solvents consist of hydrocarbon moieties or halogenated hydrocarbon moieties of the alkyl or/chloroalkyl type and have Hli low points well above room temperature.

The formulator of the raccoon composition will select the solvent partly due to the need to provide good grease rinsability and partly due to aesthetic considerations.

For example, soluble hydrocarbons work perfectly well in this composition, but may have a bad odor. Solvent oils can be used in commercial coatings. In cases where odor is not tolerated, the prescriber must use a solvent with a distinctly pleasant odor that can be reasonably modified by use of a perfumer. JjlChooseC>Shi.

Fatty Acids/Soap Components Fatty acids (generally 010" chain length) and their bathing properties (i.e., familiar soaps, especially alkali metal soaps, are considered in this article not only because of their detergent surfactant properties) fatty acids and soaps containing solvents and polyamines in an aqueous carrier, as described in further detail below. It is particularly useful when preparing a well-formulated, uniform oil-in-water liquid detergent 'e AtS.0.
Usage amounts of 5 to 50 inches are typical.

Other Optionally Ingredients The present compositions can contain other ingredients that enhance their cleaning performance. For example, it is highly preferred that through-the-wash detergent compositions contain detergent builders and/or sequestering agents. Compounds that can be classified as detergent builders and are well known in the art include, for example, nitrilotriacetates, polycarboxylates, citrates, water-soluble phosphates such as tripolyphosphate and sodium orthophosphate and sodium pyrophosphate, silica salts, and mixtures thereof. It is. Sequestering agents include, for example, all of those mentioned above, as well as substances such as ethylenediaminetetraacetate, aminopolyphosphonates and phosphates.

Generally, the builder/sequestering agent will be about 0% of the composition.
．． 5 chill would constitute 15%. Citrate is one of the most preferred builders because it is readily soluble in the aqueous phase of heavy duty liquid detergent compositions.

The composition preferably also contains enzymes to enhance through-the-wash cleaning performance for various soils and stains. Amylase and protease enzymes suitable for use in detergents are well known in the art and in commercially available liquid and granular detergents. Commercial detergent enzymes (preferably mixtures of amylase and protease) may be present in the compositions from 0.001% to

EXAMPLES IX - IX The following examples relate to compositions within the scope of the invention having solvents that are particularly suitable in industrial heavy duty laundry/cleaning plants and the like.

It is recognized by formulators that some of the solvents used in such compositions may be unsuitable for general household use due to odor, skin irritation potential, low flash points, etc. Will. However, such compositions are not suitable for use by professional operators who take such matters into account.
It is entirely suitable for use under suitably controlled conditions. In Examples 1-IX, all components are expressed in parts by weight. The polyamines A-F used in Examples 1-IX have the general formula given above and are as follows.

Thus, although the composition of each weight according to the present invention has been described, special precautions should be taken when washing all fabrics in a typical home laundry operation. A highly preferred formulation is now directed that is particularly useful as a heavy-duty liquid detergent suitable for laundering. The Hebi-Beauty liquid detergent described below is formulated using a variety of detergent ingredients to provide excellent cleaning of a variety of stains and stains, and solvents/polyamines to remove clay/grease and dirty motor oil stains from fabrics. significantly contributes to the removal of

Such formulations can be prepared as water-in-oil emulsions, but are preferably prepared in the form of oil-in-water emulsions (the solvent is considered the "oil" phase), and most preferably are substantially clear. It should be understood that it is in the form of a homogeneous oil-in-water micron emulsion.

Heavy-duty liquid detergent formulators will recognize that there are significant cost savings in using water as a carrier phase in such compositions, and
And further recognize that the aqueous carrier phase importantly contributes to ease of formulation, as water-soluble detergent ingredients can be incorporated more easily into oil-in-water emulsions than water-in-oil emulsions. Will. Surprisingly, when used in a pre-treatment process, the oil-in-water emulsions of the present invention are comparable in degreasing performance to water-in-oil emulsions containing significantly higher M solvents. The present compositions with high concentrations of surfactants and fatty acids/soaps can be placed in high density polyethylene bottles without loss of solvent.

01-0.5%) is added.

Solvent Selection As mentioned above, the final choice of solvent system to use in the present composition will depend on the type and loading of the soil, aesthetic properties (smell), etc. However, numerous criteria can be used to guide this selection. For example, the solvent should be substantially water-immiscible and, of course, should be capable of dissolving a wide range of problem greasy soils. In this latter respect, the thermodynamic solubility coefficient (Hansen coefficient) is useful in making solvent selection.

Any solvent can be described by its Hansen coefficients δd1 δ1, δh. δd is the fractional component; δ is the polar component; and δh is the hydrogen bonding component. Similarly,
The key problem, greasy stains, can also be described by "pseudo" Hansen stains. To do this, the solubility of each greasy soil in a wide range of solvents of different Hansen coefficients is first evaluated. This allows each solvent to be stirred for a fixed period of time (e.g.
minutes) can be done by soaking. Upon removal, excess solvent is drained and the soiled fabric is
% typical liquid laundry detergent for 5 minutes. After a final rinse in cold water and drying, stain removal can be assessed visually or by any other suitable technique. By proceeding with this method, the solvent that provides the best removal of each problem greasy smudge is determined, so that the range of each Hansen's coefficient required for optimal removal of a particular smudge can be evaluated. Thus, for each bleed, a map of Hansen's coefficients is obtained, and solvent/solvent combinations can be selected on this basis to give a targeted performance profile.

Although not intended to limit the present invention, the technique may include δ
d(7-9), δp(0-4), δh(.

It is shown that mixed solvent/solvent compositions with Hansen coefficients in the range of 7) form microemulsions with excellent greasy stain removal performance.

Solvent combinations are suitable for specific greasy stains, for example, where the optimal Hafsen coefficient range is δp (7-9), δh (O-4
), motor oil with δp (o ~ 3), the optimal range is δd
(7-9), δh(2-11), δp(2-7), or even more against mixed stains by selecting the midpoint within the Hansen coefficient range. Can be broadly targeted.

These solvents and solvent mixtures C typically range from 5 to 20 liters, preferably from 5 to 1 liters, in the present compositions.

Moe is used at a concentration of 1. Slightly polar solvents, such as benzyl alcohol or Un-hexanol, can be used as water-immiscible solvents, such as terpenes and . Knee R
It may be used in amounts of 0 to 10%. Various other solvent mixtures are disclosed in Example XIX below.

As can be seen from the foregoing, the present invention encompasses various formulations in the form of stable solvent-containing emulsions. A superior heavy-duty liquid detergent composition may include diethyl phthalate (preferred)-mada (diptyl phthalate and terpenes (preferably orange terpene) or dipentene, or chili-roughin oil, or mixtures thereof. (Most preferred) It can also be prepared using a liquid solvent system.

It will be appreciated that many of the above compositions containing terpene hydrocarbons will necessarily have a strong citrus odor, which is not entirely inapplicable to all formulators of such compositions. . It has now been discovered that C6-C9 alkyl aromatic solvents, particularly C6-C97/lz*/lz Hensen's octylbenzene, exhibit excellent degreasing properties and have a low pleasant odor.

Similarly, olefinic solvents, especially alpha-olefins, preferably i-decene or dodecene, having a boiling point of at least about 100'Ce are excellent degreasing solvents.

The combination of the alkyl aromatic paraffinic or olefinic solvent with a polar liquid such as benzyl alcohol, n-hexanol, butylcarpitol (trademark, 2-(2-butoxyethoxy)ethanol) or a phthalate ester is These constitute additional examples of preferred non-polar/polar solvents for use in the practice of the invention.

Constitutes H regulator and stabilizer. Apparently, such substances, in some association with fatty acids or anionic surfactants, form complexes that stabilize the microemulsified oil (solvent). Nitrogen-functional compounds do not raise pH'c much towards the alkaline range (4/10 as measured in products formulated "as is").
．． With a pI (units only) of 5, the resulting enhancement in cleaning performance, especially enzyme cleaning performance, is substantial.

Injectably, the pH of the composition is between about 6.5 and 6.6.
For H adjustment, any of the known basic substances can be used, such as triethanolamine, alkali metal hydroxides, etc. Potassium hydroxide is preferred over sodium hydroxide because the ease of formulating a stable system is substantially increased by the potassium cation.
