Definitions

• An aerosol detergent composition containing a propellent and a mixture of surface active agent and a textile optical brightening agent.
• the aerosol detergent composition is useful in pretreating highly soiled areas of textile materials prior to laundering in an aqueous detergent.
• the present invention relates to an improved detergent composition, and in particular to an aerosol formulated detergent composition which is particularly adapted for the pretreatment of the heavily soiled areas of textile products prior to conventional washing procedures, as well as for use as a high sudsing detergent product which is outstandingly useful for washing fine fabrics, particularly by hand.
• the powders are difiicult to slurry and must, generally, be used at the final laundering concentration.
• any brighteners present are also at a maximum dilution, and therefore, minimum nited States Patent concentration, thereby reducing the effectiveness of the brighteners which might ensue were they to be employed at the concentrations thereof in the concentrated, i.e., powder, formulation.
• the major disadvantage of the liquid compositions lies in the factors of accuracy, convenience and economy mentioned above.
• optical brightening agents are generally characterized by the property of absorbing ultra-violet light and converting and reemitting said radiation as visible light, preferably of the shorter wave lengths near the blue end of the visible spectrum.
• Compounds which are commercially feasible for use as optical brighteners should be substantiall colorless, substantive to the article being treated, have a high brightness rating, and have a fairly high degree of light stability,
• a synthetic detergent or wetting agent A synthetic detergent or wetting agent
• the synthetic detergent or wetting agent component of the aerosol detergent compositions of this invention are not especially critical, and may comprise any nonionic, anionic or cationic surface active substance which is compatable with the major component which is normally present in the compositions, namely the propellant, as well as the brightener.
• the propellant mixture which, as pointed out above, comprises the major portion of the composition, may be any suitable and conventional propellant heretobefore employed in the aerosol packaging industry.
• the preferred propellants are the liquefied normally gaseous halogenated hydrocarbons such as the Freon type propellants, which are usually chlorinated, fluorinated alkanes, and examples of these are:
• Freon-11 (trichloromonofiuoromethane) Freon-12 (dichlorodifluoromethane) Freon-112 (tetrachlorodifiuoroethane) Freon-113 (trichlorotrifluoroethane) Freon-114 (dichlorotetrafiuoroethane)
• Particularyly excellent propellant combinations are obtained using mixtures of Freon-11 and Freon-12 wherein the latter compound is present to the extent of about 40% to about 80% by weight based on the weight of the two propellants.
• the preferred propellant combination is a mixture of equal parts by weight of Freon-11 and Freon- 12.
• the amount of propellant in the detergent composition may vary considerably but, in general, between 50% and 80% by weight of the said detergent composition is made up of the propellant.
• the remaining 20% to 50% of the areosol detergent composition comprises a solution or dispersion of optical brightening agent and surfactant in a suitable solvent which is compatible with the propellant.
• Compatibility is usually necessary and desirable in order to produce a single phase, homogeneous formulation which can result in uniform and reproducible effects.
• the solvent employed is anhydrous ethyl alcohol, although minor amounts of water, up to about 10% by weight, may be present.
• nonpropellant component portion of the present composition by far the major portion thereof is comprised of the surface active agent. Generally, from about 75% to about 95% by weight of this nonpropellant component is made up of the surface active product. The remaining to about 25% by weight of the nonpropellant ingredients comprise the optical brightener and the solvent. In general, the concentration of the optical brightener in the final composition should vary from about 0.002% to about 0.2% by weight, with the selected concentration being dependent primarily upon the solubility of the optical brightening agent in the solvent and wetting agent which are employed.
• the surface active material may be selected from any of the conventional types which include the nonionic, anionic and cationic surface active agents, with the nonionic types being preferred.
• Such surface active, detergent materials are well known products and by way of example, mention may be made particularly to the alkylene oxide condensates of organic compounds containing a reactive hydrogen atom. Illustrations of such reactive hydrogen-containing organic compounds are aliphatic alcohols, alkyl phenols, aliphatic and aromatic carboxylic acids, the corresponding amides, aliphatic and aromatic monoand polyamines, sulphonamides, and aliphatic and aromatic monoand polymercaptans. Specific examples of these compounds may be found in the following US. patents: 1,970,578, 2,085,706, 2,205,021, 2,213,477, 3,060,124, 3,075,922, and 3,122,508, where inumerous and diifernt nonionic surface active, detergent compounds are shown.
• anionic and cationic surfactants may be further exemplified in the following US patents: 2,941,950, 3,001,949, 3,075,922, 3,122,508 and 3,192,166.
• optical brightener As with the synthetic detergent component, the specific chemical nature of the optical 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 aerosol compositions of the present invention:
• Stilbene cyanuric types as illustrated in the following U.S. 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.
• a solution of the selected optical brightener, at a suitable concentration, is prepared in an alcoholic solvent, and this is most conveniently done by the employment of elevated temperatures to aid in the dissolution of the brightener.
• the alcohol may contain minor amounts of water as described above.
• Solution A An aliquot portion of Solution A is added to the surfactant material, which is preferably a liquid or readily liquefiable surface active compound, to produce a solution of the selected brightener or brighteners in the surfactant-alcohol combination.
• the surfactant material which is preferably a liquid or readily liquefiable surface active compound
• step (C) Handling of the materials in step (C) and subsequent packaging thereof are carried out with the usual precautions and techniques in the aerosol art.
• a nonionic surface active detergent composition which is an ethoxylated nonyl phenol having the molecular configuration of the condensation product of nonyl phenol with about 10 moles of ethylene oxide, resulting in an apparently true solution of the components containing 0.0025% of the aforementioned brightener. 25 parts of this solution are then packaged with 75 parts of a 1:1 mixture of Freon-11 and Freon-12 propellants.
• Aqueous sodium silicate (36%) 10 3,431,060 6
• a random panel of five people unanimously picked (C) the pretreated collar sections as being many times whiter than the untreated control collar sections.
• propellant combinations may be any suitable ones which are conventionally used in the aerosol industry, and particularly those herein described.
• propellant compounds rather than mixtures as herein exemplified, although such mixtures are preferred.
• the aerosol-treated and washed garments are $011 l agents fa bnc softeners perfumeshand noticeably cleaner and Whiter than the others the like. Still further, it is apparent that where single components are used one may employ mixtures of the EXAMPLE 6 alternatives and equivalents which are described herein.
• a surface active agent selected from the group consisting of nonionic, anionic and cationic surface active agents, from about 0.002% to about 0.2% by weight of a textile optical brightening agent and a balance of ethyl alcohol solvent, said solvent containing up to about 10% by weight of water.
