Definitions

• the present invention relates to an improved detergent composition and in particular to an improved detergent formulation which is specifically adaptable for employment in stick form, and in which form the said compositions are outstanding for use in spotting soiled clothing prior to laundering such clothing.
• optical brightening agents are generally characterized by the property of absorbing ultra-violet light and converting and re-emitting said radiation as visible light, preferably of the shorter wave-lengths, i.e., at the blue end of the visible spectrum.
• Compounds which are commercially feasible for use as optical brighteners should be substantially colorless, substantive for the article to be treated, have a high brightness rating, have a high degree of stability in the laundering bath, and have a fairly high degree of light stability (i.e., should not decompose to colored products under normal environmental conditions of use).
• Optical brighteners are generally relatively expensive materials and therefore must perform their desired and intended function at very low concentrations.
• Usual laundry bath concentrations range from about 0.1% to about 3,417,023 Patented Dec. 17, 1968 0.5%, and when used in powdered or liquid detergent formulations, their effect is uniform throughout the entire bath. Thus, all areas of the articles being laundered are subjected to the same brightener concentration, and the more heavily soiled areas will not receive any greater amount of brightener than the cleaner areas. The net effect of this is to produce no more actual or apparent cleansing of these more soiled areas than of the less soiled portions of the laundered articles.
• lt is therefore an object of the present invention to provide new, useful and outstanding detergent compositions which are particularly adaptable for producing articles which are actually, apparently and visibly uniformly cleaned.
• compositions which comprise as the essential components thereof the following:
• Suitable fatty acids are the saturated aliphatic monocarboxylic acids of from 12 to carbon atoms, and of this group the preferred product is sodium stearate.
• an alcohol such as ethyl alcohol or isopropyl alcohol.
• the former alcohol is the preferred one to use.
• the fatty acid salt is most conveniently added to the alcohol while the latter is at an elevated temperature.
• the fatty acid salt i.e., soap
• the fatty acid salt i.e., soap
• the alcohol generally resulting in about 60 to 99% by weight of a gelled soap in the composition.
• the amount of the synthetic detergent component of the detergent stick is not especially critical and in general may range from about 1% to about by weight based on the weight of the entire composition.
• Any synthetic detergent may be used selected from the three major classes of nonionics, anionics, and cationics.
• nonionic synthetic detergents are the preferred class of compounds to be employed primarily because of compatibility problems which may arise with certain classes of optical brighteners. It is of course understood, however, that the anionics and the cationics may be used with equivalent efiiciency and results where the proper brightener is used.
• nonionic synthetic detergents are as a class, well known materials, but by way of example, mention may be made particularly of the alkylene oxide condensation with higher aliphatic alcohols, alkyl phenols, carboxylic acids, amides, amines and sulphonamides. Examples of such products may be found illustrated in U.S. Patents 1,970,578, 2,085,706, 2,205,021, 2,213,477, 3,060,124, 3,075,922, and 3,122,508.
• optical brightener As with the synthetic detergent, the specific chemical nature of the brightener is not especially critical and any of those, conventionally used and well known in the art may be employed.
• the following general classes of optical brightening agents are satisfactory for use in the compositions of this invention:
• Triazolyl stilbene types as illustrated in US. Patents 2,668,777, 2,684,966, 2,713,057, 2,784,183, 2,784,197, 2,817,665, 2,907,760, 2,927,866 and 2,993,892.
• Stilbene cyanuric types as illustrated in US. Patents 2,473,475, 2,526,668, 2,595,030, 2,618,636, 2,658,064, 2,658,065, 2,660,578, 2,666,052, 2,694,064, and 2,840,- 557.
• the amount of brightener may vary considerably but, in general from about 0.1% to about 5% by weight based on the weight of the total stick composition can be used.
• the preferred range of concentration varies from about 0.2% to about 2% on a weight basis.
• compositions of this invention The general procedure for preparing the compositions of this invention is as follows:
• the selected fatty acid is dispersed in the hot alcohol, the latter at a temperature of about 160 F.
• the mixture is stirred to insure uniformity in characteristics thereof, and then cooled in a suitable mold to the desired shape, which as pointed out above is preferably in the form of a stick.
• Example 1 grams of double pressed stearic acid are added to 255 cc. of ethyl alcohol, the latter at a temperature of about 160 F. To this dispersion there is added sutficient of a 50% aqueous sodium hydroxide solution to neutralize the stearic acid. There is then added a mixture of 0.38 gram of a brightener having the formula:
• the resultant stick is a readily handled composition.
• Example 2 Two mens shirts equally soiled, and, equally, more heavily soiled in the collar and cuff areas are selected. One of the shirts is rubbed in the heavily soiled areas with the water-moistened stick of Example 1. The other shirt is treated in the same areas with a small amount of a commercial heavy duty liquid detergent which contains about 25% polyphosphates, 10% ethoxylated nonyl phenol (60% E.O. surfactant, 1.5% CMC, 10% sodium dodecyl benzene sulphonate, and 10% of a 36% aqueous sodium silicate solution as the major ingredients. Both shirts are then laundered using the commercial heavy duty liquid detergent in a standard 30 minute wash and spin dry laundering cycle. The shirt which has been treated with the stick formulation of Example 1 is uniformly clean in all areas. The other shirt has discernible soiled areas where the garment was originally heavily soiled.
• a commercial heavy duty liquid detergent which contains about 25% polyphosphates, 10% ethoxylated nonyl phenol
• Example 3 Examples 1 and 2. are repeated except that the 10 grams of synthetic detergent used in that example is replaced by the following:
• Example 4 Examples 1, 2 and 3 are repeated replacing the brightener used in these examples by the following:
• Example Example 1 is further repeated except that the stearic acid is replaced by the following acids:
• Hydrogenated tallow fatty acids (HYFAC series).
• C Hydrogenated fish fatty acid (HYFAC series).
• D Eicosanoic acid.
• Example 6 Example 1 is repeated except that in place of the 15 grams of stearic acid, there are used the following in separate formulations:
• Example 7 Example 1 is again repeated but replacing the optical brightening agent with the following in the amounts indicated:
• a detergent stick consisting essentially of:
• a gelled soap matrix from 60 to 99 percent by weight of a gelled soap matrix.
• said matrix being a mixture of l to 10 percent by weight of a soap selected from the group consisting of alkali metal, ammonium. amine and substituted amine salt of a saturated fatty acid containing from 12-20 carbon atoms, and 60 to 95 percent by weight of an alcohol selected from the group consisting of ethyl alcohol and lsopropyl alcohol, said matrix containing as the sole additional ingredients (1) from 1 to 10 percent by weight of a synthetic detergent selected from the group consisting of non-ionic, anionic and cationic detergents, and (2) from 0.1 to 5 percent by weight of a synthetic textile-substantive optical brightening agent.
• a detergent stick as defined in claim 5 wherein the non-ionic synthetic detergent is an ethoxylated aliphatic alcohol selected from the group consisting of ethoxylated lauryl alcohol and ethoxylated oxotridecyl alcohol.
• composition as defined in claim 1 wherein the brightening agent is an optical brightener including a triazolyl stilbene moiety.
• composition as defined in claim 1 wherein the brightening agent is an optical brightener including a stilbene cyanuric moiety.
• composition as defined in claim 13 wherein the brightening agent is an optical brightener including a coumarin moiety.
