Definitions

  • the present invention relates to a wax-containing liquid detergent composition which comprises essentially a stable homogeneous suspension or dispersion of castor wax and a water-soluble higher alkyl aryl sulfonate detergent in an aqueous medium, and to processes for preparing liquid detergents, as hereinafter described and claimed.
  • liquid compositions comprising various detergents and hydrogenated castor oil, as disclosed in US. Patents No. 2,871,193 and No. 2,290,045 for example.
  • certain processing details are employed usually such as the operation of the melting of the wax and its addition as a liquid at high temperatures to the other detergent ingredients, the need for comparatively long heating times and certain cooling conditions for the entire composition in order to prepare a fine suspension and minimize a tendency to form a coarse, flaky product.
  • stable, homogeneous, fine suspensions or dispersions may be prepared in concentrated form using procedures which are particularly conducive to commercial preparation of a liquid detergent. More particularly, stable concentrates are obtained with the castor wax in extremely fine and homogeneous dispersion or pre-crystallized form comprising essentially about 1 to 18% by weight of the wax and 1 to 25% by weight of a water-soluble higher alkyl mononuclear aryl sulfonate detergent proportioned in an aqueous medium.
  • Such concentrates can be prepared by addition of a proportionate amount of castor wax in particulate form with Water in the presence of said sulfonate detergent at an elevated temperature sufiicient to melt the castor wax with agitation and forming a homogeneous liquid solution, and thereafter slowly cooling the mixture until a critical stage of emulsion or suspension formation has passed and to produce a particular phase separation wherein a homogeneous, liquid dispersion of the wax is obtained substantially free from lumps or crystals.
  • the invention relates also to a process for forming a substantially homogeneous, pourable, heavy-duty aqueous liquid detergent which comprises essentially about 5 to 30% of water-soluble organic sulfonated detergent, a water-soluble alkaline inorganic polyphosphate salt in an amount from about 5 to 30%, and a minor amount from about 0.1 to 1% by weight of the castor wax by initial formation of a wax-detergent concentrate followed by admixture at a temperature below about 140 F. with said detergent, phosphates in aqueous solution and any other ingredients to form a substantially stable and homogeneous heavy-duty liquid detergent.
  • the alkyl aryl sulfonate detergent has a higher alkyl group within the range of 8 to 18 carbons and preferably about 8 to 15 carbon atoms. It is preferred to use the higher alkyl benzene sulfonate, though other similar detergents having a mononuclear aryl nucleus, such as higher alkyl toluene and xylene sulfonates, may be used also.
  • the alkyl substituent may be branched, such as nonyl, dodecyl and pentadecyl groups, including mixtures thereof which are derived from polymers of lower-olefins.
  • the alkyl group may be straight-chained in structure such as the n-decyl, n-dodecyl and keryl groups. Preferred form of a stable dispersion.
  • materials have an alkyl group of 12 to 15 carbons such as tridecyl benzene sulfonate which has a mixture of polymerized olefins in the alkyl group corresponding on the average to about a tridecyl group.
  • Such sulfonate detergents are used preferably in the form of their alkali metal salts, such as sodium and potassium salts.
  • alkali metal salts such as sodium and potassium salts.
  • Other water-soluble salts such as the nitrogen-containing salts, e.g., lower alkylolamine salts, may be used also, examples being the ammonium, isopropanolamine, monoand tri-cthanolamine salts of the detergents.
  • the castor wax (viz. hydrogenated castor oil) may be used in any suitable grade. It is preferred to use a material having a melting point of about 8487 C. and is employed in a finely-divided form having an iodine number of about 6% maximum. Other characteristics of the preferred grade are an acid value: of 0.2% maximum and a saponification value of 17.518.5% KOH with a specific gravity at 20 C. of 0.98-1.00. Other grades of castor wax can be used also, such as grades having an iodine number up to 8.5 and an hydroxyl number of -165.
  • a concentrate of the castor wax and the alkyl aryl sulfonate detergent is prepared. in water in the In general, the process comprises heating an aqueous solution of the detergent to a temperature above F. and sufiicient to melt solid castor wax without an adverse effect on any ingredient, e.g., about -200 F., slowly adding the castor wax in particulate form with rapid agitation until it is molten and there is formed a homogeneous solution. Any suitable particulate form of the wax may be used such as thin flakes, powder, etc.

  • the heated solution should be cooled slowly with agitation at a rate not substantially in excess of 5 F., and preferably up to 3 F. per minute through a transition temperature range below 160 F., and usually from l30150 F., until a critical stage of emulsion formation occurs wherein the product assumes a smooth, milky appearance which is more viscous and opaque.
  • the wax is in such a finely dispersed, almost colloidal-like state that the particles are highly resistant to separation from the liquid.
  • the wax droplets which are pre-crystallized in this smooth grain-free emulsion form are in stabilized condition so that they do not coalesce to large crystals upon further cooling or upon aging under reasonable conditions. If the cooling is conducted from the solution state too rapidly, there is formed in the liquid comparatively large crystals or palpable lumps which tend to precipitate from the liquid phase.
  • the liquid batch may be cooled more rapidly to room temperature. It may be stored without adverse effects for later use in the manufacture of heavy-duty liquid detergents.
  • This suspension should be prepared so as to be in a pourable condition at normal room temperature of about 72 F. in order to facilitate processing.
  • Such liquids may vary in viscosity or consistency from a highly fluid to a mobile gel or semi-solid pasty condition so that the fluid mass may flow by gravity or pumped to a mixing vessel for admixture with other ingredients.
  • the amount of castor wax and sulfonate detergent in this fine aqueous dispersion is variable and should be proportioned to form a liquid having the desired physical properties.

  • the wax to detergent ratio can be varied as desired with resulting variation in the physical properties. In general, an increase in the wax concentrate tends to produce a more viscous, gel-like product with a given amount of detergent whereas an increase in the detergent tends to result in a more fluid product provided that the solids content is not excessive.
  • the amount of water should be sufficient to solubilize the detergent and permit adequate dispersion of the wax under the controlled conditions described, and is preferably at least about 50% by weight of the total concentrate.
  • This dispersion may be employed for many uses, including use as an intermediate in the preparation of other detergent (including cosmetic) compositions or use for detergent purposes directly.
  • Various selected materials may be added during or after preparation of the dispersion as desired provided the amounts of compatible materials used do not substantially affect the desired properties since the preparation is dependent upon the mutual effect exerted by the specified wax and sulfonate detergent in suitable concentrations under the specified conditions.
  • compatible detergents perfumes, coloring materials, corrosion or tarnish inhibitors, soil-suspending materials, optical bleaches or fluorescent dyes, viscosity modifiers or organic solvent materials, and the like.
  • the admixture of the dispersion with additional water, particularly, in the presence of added surface-active agent in a suitable amount, does not destroy the stability of the wax in the aqueous medium but produces an aqueous solution in which the wax is in fine, stable suspension to give an attractive opaque to translucent appearance to the liquid product.
  • the concentrate can be admixed at room temperature or at moderately elevated temperatures below the point at which the critical phase change of the concentrate occurred upon cooling with detergent to effect homogeneous products. It is preferred to prepare liquids having about 5 to 50% by weight of detergent and 0.1 to 1% of the castor wax in stable dispersion in water.

  • Any suitable minimum mixing temperature may be em ployed including room temperature depending upon the other ingredients.

Suitable silicates are those having an alkali oxide to silica ratio within the range of about 1:1 to 1:4, and preferably from about 1:2 to 1:3. Examples are sodium silicates having an Na O to S ratio of 1:2.35, 1:2.5, 1:3.2, 1:2.0, 1: 1.6 and 1 :1.
