REQUESTED NOVEMBER 11, 1964 at 3:45 pm in ΙΌ.Α. Mr. P. I. (P.V. No. 50,568) by the Society known as Unièever N.V., residing in the Netherlands. ISSUED 15 JULY 1966, published in Official Bulletin No. 6/7 of 1966. PRIORITY: Patent application filed in Great Britain under No. 12.170 on 6 April 1960 in the name of the plaintiff.
Liquid detergent compositions.
The present invention relates to detergent compositions, and more particularly to abrasive compositions in liquid form.
Abrasive detergent compositions in the form of breads, lozenges, dry powders or pasta containing a limited amount of water or other liquid are known. They contain a finely divided, water-insoluble, brittle material (which is subsequently referred to simply as "abrasive") and a proportion of a water-soluble detergent, such as a soap.
It has now been found that effective amounts of abrasive can be incorporated into certain suspen-sions and aqueous detergent solutions to yield substantially stable and pourable compositions. "Substantially stable" means that the composition, after being stored at the temperature During periods of at least several weeks, it does not separate into layers or this separation is small and the homogeneous product can easily be formed by medium agitation.
The present invention provides a substantially water-soluble and pourable suspension of a finely divided and water-insoluble substance in a liquid medium comprising substantially water, anionic detergent and a nonionic surfactant.
Any water-insoluble and finely divided, non-abrasive material normally used in abrasive detergent compositions, such as fine silica, feldspar, stone, kieselguhr or carborundum, may be used as an abrasive. The particle size should be such as to provide effective abrasiveness without undesirable scratches, and any abrasive which meets these requirements can be used to form substantially stable compositions in accordance with the present invention. Typical dimensions of the abrasive action are those for which the product passes substantially all through a sieve having openings of 104 microns on one side and at least 83% through a sieve having openings of 53 microns on one side, and Any abrasive whose particles have dimensions included in this range can be effectively incorporated in the compositions according to the present invention. It is also possible to use abrasives whose particles have an average size of less than 10 microns in diameter, such as tripoli. However, for some applications, such as scraping or painting roughing, removal of rust on iron surfaces or similar applications, it may be desirable to use coarser abrasiveparticles and good results have been prepared. substantially stable suspensions containing abrasive particles whose size reaches up to 0.35 mm. Particles of this size are of course covered by the term "finely divided".
The amount of abrasive to be incorporated into the compositions of the present invention may vary between extended ranges, depending on the desired properties of the composition; Normally, any particular liquid medium which has suspending properties can suspend any amount of abrasive. However, if an excessive amount of abrasive is added to the liquid medium, the resulting product can no longer be poured, but is in the form of a paste. Usually, an amount of at least about 5%, based on the weight of the total composition, is required to provide effective abrasive action, and amounts up to 50% can often be satisfactorily incorporated. It is preferred to use a quantity of between 20% and 45%.
The liquid medium must contain the constituents indicated in such proportions that the abrasive is maintained in the form of a substantially stable suspension. Leterme "liquid medium" means the composition on ex-clusion only of the abrasive substance that is suspended therein. The liquid medium may itself contain a suspended substance. The particular components and proportions used are to be selected so that a substantially stable suspension is achieved in accordance with the present invention. While seemingly insignificant changes may destroy the stability of the suspension, substantially stable products according to the present invention may be prepared according to the instructions and advice given in the following paragraphs of the description as well as in many specific examples. A single test will show whether any particular composition will form a substantially stable suspension.
The anionic detergent used may be a synthetic anionic soap or detergent, or a mixture of unsavon and anionic synthetic detergent.
Various synthetic anionic detergents may be used in the compositions according to the present invention, such as alkylaryl sulfonates, alkyl sulphates and acylaminoalkane sulphonates, but alkylaryl sulphonates are preferred. It has been found that sodium dodecylbenzene sulphonate is particularly satisfactory. Compositions containing acyl isothio-nates tend to be unstable and are not recom- mended, while those containing alkyl sulphates tend to exhibit intermediate stability, although many compositions capable of satisfying using these types of synthetic anionic detergents through appropriate choice of other components and their proportions.
The soap used may be any soap of a kind normally used in detergent compositions, such as sodium or potassium soap derived from tallow oil, palm oil or decoprah oil. The maximum amount that can be used with high results can depend on its solubility in water, and it may be advantageous to use soaps with greater solubility, such as potassium soaps, especially potassium soaps. "sweet" oils like peanut oil.
The amount of anionic detergent used is generally between 3 and 15% by weight of the liquid medium. The preferred range is between 6 and 12%.
In general, the soap should not be less than 0.8% or more than 12% by weight of the liquid medium. Preferred ranges are from 1 to 7% when also using synthetic anionic detergent, and from 5 to 12% when soap is the only anionic detergent component.
It is preferred to use from 1 to 9% of the anionic synthetic detergent relative to the weight of the liquid medium.
Among the nonionic surfactants which can be used in the compositions according to the present invention, there may be mentioned the condensation products lower alkylene oxides, for example ethylene oxide, with alkylphenols, fatty acids, alcohols fat and similar substances. Particularly satisfactory compositions can be prepared by using a fatty acid alkanolamide, preferably a mono- or diethanolamide, but other alkanolamides having similar properties, such as isopropanolamides, glycerolamides and tris (hydroxymethyl) methylamides, can be equally effective. It is preferred to use a mono- or diethanolamide of a fatty acid having from 8 to 18 carbon atoms in the molecule, especially the mono- or diethanolamide of lauric acid or of a mixture of acids rich in lauric acid, such as can be obtained from oils like palm kernel oil or coconut oil. It has been found that the diethanolamide of lauric acid is particularly satisfactory. When a large amount of the nonionic surfactant is used, some of this agent may be in the form of a dispersion in the liquid medium. This has no detrimental effect on the properties of the composition. It is preferred to use from 1 to 12% of the nonionic surfactant relative to the weight of the liquid medium.
The various ionic components of the compositions according to the present invention may be used in the form of an alkali metal salt, ammonium salt or substituted ammonium salt, for example in the form of ethanolammonium salts.
It is also possible to incorporate additional substances such as perfumes, coloring agents and germicidal agents provided that their nature and quantity are not such as to destroy the stability of the composition. A cosolvent such as glycerin may be present in the liquid medium in amounts comparable to the amounts of anionic and nonionic substances. Certain soluble inorganic salts such as sodium carbo-nate, sodium sulfate, sodium bicarbonate and borax may be included in the compositions of the invention in amounts up to 10% by weight of the liquid medium. It may, however, be desirable to attempt to incorporate appreciable amounts of sodium carhoxymethylcellulose and strong hydro-tropes such as sodium xylene sulfonate.
The choice of the non-aqueous substance and the proportions to be used in the liquid medium are determined independently of the desire to obtain a powder providing adequate suspension suspension, by considerations such as detergency, foaming and emulsification properties. fats as well as the viscosity that the final product must possess. The viscosity of the compositions object of the invention is not only a function of the percentage of non-aqueous substance in the liquid medium or the percentage of abrasive substances in the composition, but it is also a result of the compositions considered as a whole. Compositions according to the invention have been prepared in the form of creams in which the proportions of non-aqueous substances are between 8.3 and 23.3% relative to the weight of the liquid medium.
The compositions of the present invention can be prepared as follows: the anionic detergent is added to water at about 60 ° C and the mixture is stirred until the detergent is dissolved. The solution is allowed to cool to about 40 ° C., and the nonionic surfactant and any cosolvent are added while acting moderately. The abrasive is then slowly added, still with gentle stirring, until the mixture is thoroughly mixed. Any additional product can then be incorporated in a small amount. 3 [00488]
Throughout this process, the mixture should be of such a nature that there is no exagerated aeration. The following examples illustrate the present invention, the values given being in each case percentages by weight. The fine silica used in these examples is of such a granulometry that substantially the laterity of the silica passes through a sieve with 104 micron openings and at least 80% of this silica passes through a sieve with 53 micron openings. next to.
