Generally, however, it may be said that the total thereof should not exceed 10% and will preferably be maintained less than 5% and more preferably less than about 3%. Individual components should usually not exceed 5% preferably 3% and more preferably 1% of the product. The use of more of such compounds will often significantly change the properties of the liquid detergent and, therefore, is to be avoided.
  • the heavy duty liquid detergents of the present invention can be made by simple manufacturing techniques which do not require any complicated equipment or expensive operations.
  • the optical brighteners may be slurried in the monohydric alcohol or mixture of monohydric and polyhydric alcohol. If initially slurried in the monohydric alcohol, subsesequently the polyhydric alcohol, if used, may be added to this. Then water and, if necessary, a small amount of base such as triethanolamine is added, which helps to partially dissolve the previously suspended material but not yield a clear solution. Addition of the detergent combination causes the remainder of the brightener to dissolve to make a clear solution.
  • the sequestrant if used, may be added as the acid or salt (preferably the sodium, potassium or amine salt) and agitation is continued until the solution becomes clarified, which will normally take about 5 to 10 minutes.

  • a typical and preferred formulation of this invention containing about 40% of the fatty alcohol-ethylene oxide condensate and ethoxamer sulfate, only about 2 ounces or A cup of liquid need to be used for a full top-loading automatic machine tube of d wash, in which the water volume might be from 15 to 18 gallons.
  • the concentration of liquid detergent in the wash water is on the order of 0.1%, 1 gram per liter or 1,000 parts per million.
  • the proportion employed will be from 0.7 to 1.5 grams per liter, which may correspond to 0.3 to 0.6 g./l. of the mixture of fatty alcohol-ethylene oxide condensation products, from 0.075 to 0.15 g./l. of ethoxamer sulfate, from 0.01 to 0.05 -g./l. of the fluorescent or optical brightener, from 0.05 to 0.4 g./l. of lower monohydric alcohol and from 0.005 to 0.03 g./l. of organic sequestrant.
  • the proportions of other constituents of the liquid compositions may vary accordingly.
  • wash water of reasonable hardness and at an elevated temperature the present invention is also useful in laundering clothes and other items in hard waters and in extremely soft waters, as well as in waters at room temperature or below.
  • water hardnesses may range from 0 to over 300 parts per million as calcium carbonate and washing temperatures may be from 10 C. to 80 C.
  • the temperatures will be from room temperature, 20 to C., to 70 C.
  • washing will ordinarily be effected in an automatic washing machine, with the washing followed by rinse and spin or draining or wringing operations, it is contemplated that the detergent may also be used for hand washing of laundry.
  • the concentration in water of the liquid detergent will often be increased and sometimes it may be full strength to assist in washing out otherwise difficult to remove soils or stains. After completion of the washing and spinning operations, it will be general practice to dry the laundry in an automatic dryer soon thereafter but such particular drying operation is not necessary.
  • the liquid composition gels within a short period of time when exposed to the atmosphere. Furthermore, the liquid detergents without sufficient low molecular weight non-ionic, i.e. at least 50% of the non-ionic detergents, to retard or eliminate this gelling do not disperse properly in water after exposure to the atmosphere. If the liquid detergent gels and does not disperse properly in water, this causes the brighteners to be concentrated in small areas causing uneven and splotchy brightening.
  • composition of the present invention will now be more fully illustrated by the following specific examples which are illustrative and in no way limitative of the present composition wherein all parts and percentages are by weight and temperatures in degrees Fahrenheit unless otherwise noted.
  • EXAMPLE 1 A clear, liquid detergent having the following formula is prepared by slurrying the mixture of optical brighteners in SD-40 alcohol followed by the addition of water and triet hanolamine with stirring. Subsequently, the Neodol 25-7 and the Neodol 25-3S is added and after a few minutes of agitation at moderate speed the solution becomes clear.
  • the pH of a 25% solution of the above formulation in water is about 7.0.
  • This liquid detergent which is a sparkling, clear, free-flowing liquid is then packed in polyethylene plastic bottles of substantially cubic shape and of one quart capacity and is ready for use. Storage tests indicate that this product Will be stable for several years without precipitation of insoluble salts, settling into a plurality of phases, clouding or other disadvantageous effects on appearance or function.
  • Detergency and brightening power of the liquid detergent composition is evaluated in control tests wherein the experimental formula is compared with various commercial heavy duty ecology type laundry detergents.
  • cloths are intentionally soiled with a mud soil and washed in identical washing machines (Terg-o-tometer)"using the same Water and recommended amounts of the experimental and various controlled detergents.
  • the soiled cloths are collected and divided so that'the experimental and controlled formulas are used to Wash similarly soiled loads of laundry. Such testing is repeated and the whiteness of the various washed cloths are compared each time by Reflectometer. Results of these tests in both hot and cold washing water conditions are listed in Table 1.
  • Example 1 cleans better at a lower concentration than other commercially available ecology type, i.e. biodegradable and non-phosphate containing, detergent compositions. Furthermore, the formulation of Example 1 cleans better at a lower wash water concentration as exhibited in Table 1 14 which shows that a concentration of only 0.09 is necessary as opposed to up to 0.3 for some other ecology type detergents.
  • the present formulation can be utilized in a concentration which corresponds to approximately cup per 16-gallon automatic washing machine tube and that at such concentration the liquid detergent favorably compares with other washing products wherein concentrations corresponding to 1% cups of spray-dried heavy duty laundry detergents must be used.
  • Reflectometer readings of Whiteness when the formulation of Example 1 is compared against various laundry detergents built with polyphosphates show no significant difference between the detergents.
  • subjective evaluations of the product in consumer tests using a panel of housewives result in a significant preference for the liquid detergent.
  • Example 1 Since no builder is utilized, it has been theorized that particulate soil could accumulate on washed items, however, subsequent to repeated washings shows that the laundry detergent of Example 1 compares quite favorably with the phosphate detergents with regard to particulate soil removal.
  • EXAMPLE 2 A series of liquid detergent compositions are produced utilizing the basic formula of Example 1 where in the Neodol 25-7 is replaced with the following non-ionic detergents:
  • Samples (A) through (D) do not gel within 18 hours and are dispersed readily upon pouring into both hot and'cold water.
  • Samples 3(E) and 15 (F) became gelled within minutes exposure to the atmosphere and are not readily dispersible in hot or cold water.
  • EXAMPLE 4 Examples 2(A) through (F) and (K) and (L) are repeated varying the total amount of non-ionic detergent from 40% to the following with a concomitant increase or decrease in total amount of water and alcohol:
  • A C ether sulfate containing 2 moles of condensed ethylene oxide
  • B C ether sulfate containing 2 moles of condensed ethylene oxide
  • C C ether sulfate containing 5 moles of condensed ethylene oxide
  • D C ether sulfate containing 3 moles of condensed ethylene oxide
  • E C ether sulfate containing 6 moles of condensed ethylene oxide.
  • composition of the present invention has been illustrated by way of the foregoing specific examples, the composition of the present invention is to be in no way limited thereto but to be construed as broadly as any and all equivalents and as properly defined in the following appended claims.
