Photochemical singlet oxygen generators having cationic substantivity modifiers

Description

FIELD OF THE INVENTION

The present invention relates to photochemical singlet oxygen generators having a cationic axial substituent which enhances the substantivity of said singlet oxygen generators for fabric surfaces. The photochemical singlet oxygen generators described herein are useful in laundry detergent compositions as bleaching agents. The present invention also relates to methods for bleaching fabrics with the photochemical singlet oxygen generators.

BACKGROUND OF THE INVENTION

It is known that certain water soluble phthalocyanine, naphthalocyanine, mixed cyanine and metallocyanine compounds can be used as photobleaching and anti-microbial agents. Phthalocyanines, naphthalocyanine, mixed cyanine and metallocyanines can form “singlet oxygen”.

Singlet oxygen can be formed by chemical as well as photochemical processes. Singlet oxygen is a highly oxidative species capable of reacting with substances, for example, with stains on a fabric to bleach them to a colorless and usually water-soluble state. There are many examples of phthalocyanines and naphthalocyanines photobleaches, the most common being the zinc and aluminum phthalocyanines. In the literature the term “photosensitizer” is often used instead of “photoactivator” and may therefore be considered as standing equally well for the latter term used throughout this specification.

The prior art teaches phthalocyanine and naphthalocyanine compounds having the general structure

where Me is a transition or non-transition metal (Sens.) is a phthalocyanine or naphthalocyanine ring which, when combined with a suitable Me unit, is capable of undergoing photosensitization of oxygen molecules, R units are substituent groups which are bonded to the photosensitization ring units (Sens.) to enhance the solubility or photochemical properties of the molecule, and Y units are substituents associated with the metal atom, for example, anions to provide electronic neutrality.

It has been a task of formulators of photobleaches to modify the properties of the (Sens.) unit of the molecule to increase the quantum efficiency without reducing the water solubility. Typically this has been accomplished by substitution on the photochemical (Sens.) ring. However, substitution on the macrocyclic ring is frequently difficult and can adversely affect other photobleach properties such as color, substantivity and photoefficiency.

Surprisingly, it has been found that the compounds of the present invention allow formulators to increase the photoefficiency of the singlet oxygen generators without adversely affecting the other parameters of the molecule. In addition, the substantivity of the photochemical singlet oxygen generator for fabric surface can be modified without producing an undesired effect in the photophysics of the molecule. This ability to delineate and selectively modify these key structural elements contributing to the target properties of the molecule allows the formulator to proceed without having to rely upon a “hit and miss” stratagem.

The present invention provides a means by which an effective photosensitizer can be made to have an enhanced affinity for the surface of fabric, especially cotton fabric. This task is achieved by attaching an axial cationic moiety to the singlet oxygen generator. This axial cationic moiety is capable of interacting with various surfaces, especially fabric surfaces which can contain a negative charge. By this interaction, the cationic group draws the photoactive singlet oxygen producing portion of the molecule into proximity with the surface of the fabric where the bleaching action of the photosensitizer can take place on stains.

It is therefore an object of the present invention to provide photochemical singlet oxygen generators which serve as photobleaches and which have a higher efficiency for cleaning stains on fabric. It is a further object of the present invention to provide photobleaching compositions suitable for use as laundry detergent bleaching compositions.

It is a yet further object of the present invention to provide enhanced photobleaching hard surface cleaning compositions for non-porous hard surfaces, inter alia, Formica®, ceramic tile, glass, or for porous hard surfaces such as concrete or wood.

It is a still further object of the present invention is to provide a method for bleaching fabric with laundry compositions comprising the photobleaching compounds of the present invention.

It is yet still a further object of the present invention is to provide a method for cleaning hard surfaces with the photobleaching compounds of the present invention.

Anionic surfactants can be broadly described as the water-soluble salts, particularly the alkali metal salts, of organic sulfuric reaction products having in their molecular structure an alkyl radical containing from about 8 to about 22 carbon atoms and a radical selected from the group consisting of sulfonic acid and sulfuric acid ester radicals. (Included in the term alkyl is the alkyl portion of higher acyl radicals.) Important examples of the anionic synthetic detergents which can form the surfactant component of the compositions of the present invention are the sodium or potassium alkyl sulfates, especially those obtained by sulfating the higher alcohols (C8-18 carbon atoms) produced by reducing the glycerides of tallow or coconut oil; sodium or potassium alkyl benzene sulfonates, in which the alkyl group contains from about 9 to about 15 carbon atoms, (the alkyl radical can be a straight or branched aliphatic chain); sodium alkyl glyceryl ether sulfonates, especially those ethers of the higher alcohols derived from tallow and coconut oil; sodium coconut oil fatty acid monoglyceride sulfates and sulfonates; sodium or potassium salts of sulfuric acid ester of the reaction product of one mole of a higher fatty alcohol (e.g. tallow or coconut alcohols) and about 1 to about 10 moles of ethylene oxide; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfates with about 1 to about 10 units of ethylene oxide per molecule and in which the alkyl radicals contain from 8 to 12 carbon atoms; the reaction products of fatty acids are derived from coconut oil sodium or potassium salts of fatty acid amides of a methyl tauride in which the fatty acids, for example, are derived from coconut oil and sodium or potassium beta-acetoxy- or beta-acetamido-alkanesulfonates where the alkane has from 8 to 22 carbon atoms.

Additionally, secondary alkyl sulfates may be used by the formulator exclusively or in conjunction with other surfactant materials and the following identifies and illustrates the differences between sulfated surfactants and otherwise conventional alkyl sulfate surfactants. Non-limiting examples of such ingredients are as follows.

Conventional primary alkyl sulfates, such as those illustrated above, have the general formula ROSO3−M+ wherein R is typically a linear C8-22 hydrocarbyl group and M is a water solublizing cation. Branched chain primary alkyl sulfate surfactants (i.e., branched-chain “PAS”) having 8-20 carbon atoms are also know; see, for example, Eur. Pat. Appl. 439,316, Smith et al., filed Jan. 21, 1991.

Conventional secondary alkyl sulfate surfactants are those materials which have the sulfate moiety distributed randomly along the hydrocarbyl “backbone” of the molecule. Such materials may be depicted by the structure

wherein m and n are integers of 2 of greater and the sum of m+n is typically about 9 to 17, and M is a water-solublizing cation.

The aforementioned secondary alkyl sulfates are those prepared by the addition of H

to olefins. A typical synthesis using alpha olefins and sulfuric acid is disclosed in U.S. Pat. No. 3,234,258, Morris, issued Feb. 8, 1966 or in U.S. Pat. No. 5,075,041, Lutz, issued Dec. 24, 1991. The synthesis conducted in solvents which afford the secondary (2,3) alkyl sulfates on cooling, yields products which, when purified to remove the unreacted materials, randomly sulfated materials, unsulfated by-products such as C10 and higher alcohols, secondary olefin sulfonates, and the like, are typically 90+% pure mixtures of 2- and 3-sulfated materials (some sodium sulfate may be present) and are white, non tacky, apparently crystalline, solids. Some 2,3-disulfates may also be present, but generally comprise no more than 5% of the mixture of secondary (2,3) alkyl mono-sulfates. Such materials are available as under the name “DAN”, e.g., “DAN 200” from Shell Oil Company.

ADJUNCT MATERIALS

The following are non-limiting examples of adjunct ingredients suitable for use in either laundry or hard surface cleaning or disinfecting compositions according to the present invention.

Chelating Agents—The photo disinfectant compositions herein may also optionally contain one or more iron and/or manganese chelating agents. Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. Without intending to be bound by theory, it is believed that certain chelating agents will interact with photodisinfectants of the present invention to increase their absorbency in the visible light spectrum. This is a process that is due to the ability of chelating agents to help effect the “substantiveness” of the compounds of the present invention.

Amino carboxylates useful as optional chelating agents include ethylenediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates, ethylenediamine tetraproprionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein.

A preferred biodegradable chelator for use herein is ethylenediamine disuccinate (“EDDS”), especially the [S,S] isomer as described in U.S. Pat. No. 4,704,233, Nov. 3, 1987, to Hartman and Perkins.

If utilized, these chelating agents will generally comprise from about 0.1% to about 10% by weight of the detergent compositions herein. More preferably, if utilized, the chelating agents will comprise from about 0.1% to about 3.0% by weight of such compositions.

Inert Salts. The inert salts (filler salts) used in the compositions of the present invention can be any water-soluble inorganic or organic salt or mixtures of such salts which do not destabilize any surfactant present. For the purposed of the present invention, “water-soluble” means having a solubility in water of at least 1 gram per 100 grams of water at 20° C. Examples of suitable salts include various alkali metal and/or alkali earth metal sulfate, chlorides, borates, bromides, fluorides, phosphates, carbonates, bicarbonates, citrates, acetates, lactates, etc.

Specific examples of suitable salts include sodium sulfate, sodium chloride, potassium chloride, sodium carbonate, potassium sulfate, lithium chloride, lithium sulfate, tripotassium phosphate, sodium borate. potassium bromide, potassium fluoride, sodium bicarbonate, magnesium sulfate, magnesium chloride, sodium citrate, sodium acetate, magnesium lactate, sodium fluoride. The preferred salts are inorganic salts preferably the alkali metal sulfates and chlorides. Particularly preferred salts, because of their low cost are sodium sulfate and sodium chloride. The salts are present in the compositions at levels of from 0% to 40%. preferably 10% to 20%.

EXAMPLE 1

Preparation of Silicon Phthalocyanine Dichloride

To a mixture of 1,3-diiminoisoindoline (0.333 gm, 2.3 mmole) and anhydrous quinoline (15 mL) under argon blanketing is added silicon tetrachloride (1.1 g, 6.5 mmole).
