Description
United States, Patent 3,232,878 LIQUID DETERGENT COMPOSITIONS Thomas Gwilyrn Jones, Bebington, and David Wilham Stephens, Rock Ferry, England, assignors to Lever Brothers Company, New York, N.Y., a corporation of Maine No Drawing. Filed Feb. 27, 1961, Ser. No. 91,619
- 5 Claims. (Cl. 252-110) The present invention relates to liquid detergents and, in particular, to liquid detergents in the form of stable pourable suspensions based on soap.
It is generally desirable to produce detergent compos1- tions in the form of liquids in order to obtain convenience of measurement and application. Such liquids must contain the active ingredients in high concentration in order thatthey shall not be excessively bulky, but must be homogeneous and remain substantially homogeneous on storage in order that successive proportions withdrawn from the container have substantially the same composition. Compositions in which the active ingredients are all present in solution may not be sufficiently concentrated for commercial use but when the concentrations of the ingredients, or of one or some of them are increased above the corresponding solubilities (allowing for the effects of mutual solubilization or salting-out) the undissolved mat ter normally tends to settle out during storage and the desirable homogeneity is lost. table liquid suspensions based on anionic synthetic organic detergents are known, but compositions of this type based on soap have not been described heretofore.
It is an object of the present invention to provide stable, pourable, homogeneous liquid detergent. compositions based on soap. Another object of the present invention is to provide a method of preparing such compositions. These and other objects of the present invention will be come apparent as the description proceeds.
According to the present invention, a stable, pourable, homogeneous, liquid detergent composition in the form of an aqueous suspension comprises soap, a fatty acid alkanolamide and an alkali-metal tripolyphosphate.
The soap may be a sodium, potassium, ammonium or substituted ammonium soap derived from the oils and fats normally used in soap-making, such as coconut oil,
groundnut oil, palm oil, palm kernel oil and tallow. Sodium and potassium coconut oil soaps have been found particularly useful. At least 0.8% of soap must be present in the compositions to ensure their stability. Up to especially 2 to 6%, by weight of the composition, may be used.
The fatty alkanolamide will be one of a type normally used in detergent compositions and it is preferred to use a monoor dilower alkanolamide especially a monoor diethanolamide, particularly one derived from a C1044 fatty acid. Lauric diethanolamide or the diethanolamides of the fatty acids of coconut oil are especially useful. At least 2% of the alkanolamide is required for stability but up to about may be used, a preferred range being 3 to 7%.
The tripolyphosphate to be used may be a sodium or potassium tripolyphosphate, sodium tripolyphosphate being preferred. The amount of this ingredient is not critical, provided that it is in excess of its solubility in the solution of the other ingredients, but for good washing properties it is preferred to use at least 10%, preferably 15 to 35%, by Weight of the composition.
Various other ingredients may be added in small proportions without adversely affecting the stability of these compositions such as for instance, lanolin, coloring matters, perfumes, germicides and soil-suspending agents such as sodium carboxymethylcellulose. Where such ingredi- 3,232,878 Patented Feb. 1, 1966 ICC cuts are insoluble in the aqueous phase they are, where sufiiciently finely subdivided, held in suspension in the same way as the excess of condensed phosphate.
Certain substances may, however, destabilize the suspensions or convert them into non-pourable pastes and should not be included in these compositions in more than very small amounts, if at all. There may be mentioned particularly: solubilizing agents such as urea, certain fluorescent brightening agents and non-ionic detergents of the ethylene oxide condensate type. Whether r not any particular substance will destabilize or unduly thicken these compositions can readily be found by simple trial in each case.
. The compositions are in the form of stable homogeneous liquids, containing part of the tripolyphospate in suspension and range, in respect of their viscosity, from highly mobile liquids'to thick barely pourable'creams. The viscosity depends mainly on the concentrations of the alkanolamide and the soap. Higher concentrations of alkanolamide, within the given range, tend to diminish the viscosity while higher concentrations of soap, within the given range, tend to increase the viscosity. Thus a composition with a low concentration of alkauolamide and a high concentration of soap may be too still to pour satisfactorily. On the other hand, compositions with a low concentration of alkanolamide and a low concentration of soap tend to be either unstable or to form gels. -In general, therefore, when a low concentration of alkanolamide, within the given range (say 2 to 5%) is used, the amount of soap should be within the preferred range of 2'to6% in order to obtain stable pourable suspensions.
The compositions of the invention may be made by the following procedure:
The tripolyphosphate is added with stirring to the req uisite amount of water to give a smooth cream; normally about 1 /2 times the weight of tripolyphosphate will be required. The soap is dissolved in the remaining water at about60 C. The alkanolamide is thoroughly incorporated in the soap solution, and themixture is thenfadded to the tripolyphosphate cream, and the whole is thori oughly mixed. Any minor constituents may then be added. j 'fl Some commercial batches of tripolyphosphate do not give the required smooth cream when added to Water, but a product containing gritty particles or hard lumps'l This difficulty can be overcome either by partially prehydrating the tripolyphosphate-f0r example, to a water content of about 1%--or by mechanical treatment of the initial product.
Products of the invention have excellent washing and lathering properties, especially for line goods such as woolens, at suitable dilutions and do not form scum even in very hard water.
The following examples illustrate the present invention without, however, limiting the same thereto.
The following compositions were prepared by the method described above.-
