Definitions

  • This invention relates to a detergent composition and, more specifically, a detergent composition suitable for dip washing or cleansing.
  • Detergency or cleansing power of these detergents is functioned by their foaming ability and their ability of emulsifying oils which are exerted by applying a mechanical force to the aqueous solution of such detergents (such solution is here and there referred to as "cleansing liquid" in this specification.) That is to say, the conventional detergents for tableware relied their cleansing power largely on the foaming ability and the stability of the emulsion system.
  • Detergency of a surface active agent is generally considered as such phenomena as emulsification, solubilization and dispersion which are caused by the decrease of the interfacial tension functioned by the surface active agent.
  • the decrease of interfacial tension which is an important factor of cleansing has not been properly regarded, because there has been a limitation imposed by the requirement for the consideration to the least irritation or stimulant to the skin.
  • Another reason is that the foaming ability of a detergent has customarily been adopted as a standard for the cleansing power.
  • the present inventors have made extensive studies on the relations between the interfacial tension and/or penetrating speed of aqueous solutions of detergents and their cleansing power. As a result the inventors have found that the cleansing liquid having an interfacial tension to a triglyceride phase of not more than 0.5 mN.m- 1 and/or an penetrating speed in a triglyceride phase of not less than 5 x 10- 9 m.sec- 1 are particularly effective for use for washing tableware without relying upon the manual labor. Such finding has led to the completion of this invention.
  • an object of this invention resides in an improvement in a detergent composition comprising one or more surface active agents and, as required, a water soluble inorganic salt, organic salt or polymeric compound, said improvement being characterized in that the cleansing liquid containing said detergent composition has an interfacial tension to a triglyceride phase of not more than 0.5 mN.m -1 and/or a penetrating speed in a triglyceride phase of not less than 5 x 10- 9 m. sec - 1 .
  • Figure 1 shows a perspective illustration of a device for measuring the cleansing power, in which the numeral 1 indicates a glass sheet on which oily stains are coated and the numeral 2 indicates a holder for the slide glasses.
  • the device is set in a container 3 containing the cleansing liquid to be tested.
  • FIG. 2 is a drawing showing a device for measuring the penetrating speed in triglycerides.
  • the numeral 4 indicates a stainless plate on which a thin film 5 of the mixture of beef tallow and rapeseed oil is coated.
  • the numeral 6 indicates a drop of the aqueous solution of the detergent to be tested.
  • the stainless plate 1 is connected to an oscilloscope 8 via electrodes 7.
  • interfacial tension of a detergent in a triglyceride is defined as the interfacial tension between the cleansing liquid and the triglyceride as measured when the triglyceride is added to and reaches the solubility equilibrium at 25°C in the cleansing liquid with the detergent concentration of 3 wt%.
  • the penetrating speed of a detergent to a triglyceride is calculated according to the period of time required for a 0.05 ml drop of the aqueous detergent solution of a 0.05 wt% concentration (as surface active agents) to pass through a thin film of the triglyceride of a 20 ⁇ 3 ⁇ thickness coated and dried on a sheet of glass as described hereinafter in detail in the example.
  • the present inventors have made studies on the higher concentrations of salts, e.g., more than 0.05 wt% of sodium chloride or sodium sulfate, in combination with conventional ionic surface active agents such as sodium alkylbenzenesulfonate and sodium alkylbenzensulfate, and as a result, have found that the cleansing liquid with such higher salts concentrations exhibited a lowered interfacial tension to triglycerides, a higher penetration in the triglycerides phase, and a greater cleansing power, e.g., 10 to 100 times of that obtained by the cleansing liquid with conventionally utilized lower salts concentrations.
  • salts e.g., more than 0.05 wt% of sodium chloride or sodium sulfate
  • conventional ionic surface active agents such as sodium alkylbenzenesulfonate and sodium alkylbenzensulfate
  • the detergent composition may be prepared by incorporating the following ingredients at a prescribed ratio. That is; conventional surface active agents, including ionic, nonionic, cationic and amphoteric surface active agents; surface active materials, including, for example, oil soluble higher alcohols such as cetyl alcohol and dodecyl alcohol; inorganic salts such as sodium tripolyphosphate, sodium sulfate, magnesium sulfate and sodium carbonate; organic salts such as sodium citrate, sodium and p-toluenesulfonate; and polymeric compounds such as sodium polyacrylate and cationized cellulose.
  • conventional surface active agents including ionic, nonionic, cationic and amphoteric surface active agents
  • surface active materials including, for example, oil soluble higher alcohols such as cetyl alcohol and dodecyl alcohol
  • inorganic salts such as sodium tripolyphosphate, sodium sulfate, magnesium sulfate and sodium carbonate
  • organic salts such as sodium citrate, sodium and p
  • many of the detergent compositions having a penetrating speed in a triglyceride phase of not less than 5 x 10- 9 m.sec- 1 may be prepared by the combination of an ionic surface active agent and an inorganic salt of a high concentration.
  • compositions Nos. 1 - 26 were prepared according to the formulations in the tables below, and the interfacial tension and/or penetrating speed for each composition were measured and given in the tables.
  • compositions prepared by surface active agents conventionally used for kitchen detergents are prepared by surface active agents conventionally used for kitchen detergents:
  • compositions of other typical ionic/nonionic surface active agents systems Compositions of other typical ionic/nonionic surface active agents systems
  • compositions comprising ionic surface active agents and water soluble inorganic salts
  • compositions comprising cationic surface active agents and water soluble inorganic salts
  • compositions of this invention particularly preferred are those having the interfacial tension to a triglyceride phase of not more than 0.5 mN.m- 1 and the penetrating speed in a triglyceride phase of not less than 5x10- 9 m . sec - 1 .
  • additives may be incorporated in the composition of the present invention to the extent they are compatible with the purpose of this invention.
  • additives may be those conventionally employed in detergent compositions and include fluorescent whiteness improvers, bactericides, antideposition agents, colorants, perfumes, foam controlling agents, enzymes, solubilizers and the like.
  • the composition of this invention exhibits a high cleansing power with a moderate mechanical force, or even without any mechanical force, and without using an alkali agent. Therefore, the composition can be utilized not only as a detergent for tableware and dishes, but also as detergents or cleansing agents of a variety of articles including clothes, various housefurnishings, bathtubs, and the like.
  • the detergent composition can be applicable to an industrial purposes as well.
  • compositions comprising ionic surface active agents, nonionic surface active agents and inorganic salts as shown in Table 1 were prepared, and the cleansing power, interfacial tension and penetrating speed in a triglycerides phase were measured on each of the compositions. The results are shown in the same Table 1.
  • Stains made of beef tallow and rapeseed oil of a weight ratio of 9/1 dissolved in chloroform to a concentration of 40 wt% were put on slide glasses and air-dried. Each 6 pieces of the slide glasses were weighed in advance (weight: W 1 ). The amounts of stains put on the glasses were so adjusted that the average weight on each of the pieces may be 0.140 ⁇ 0.010 g (W 2 ).
  • Each set of 6 slide glasses stained as above was dipped for 3 minutes and at 25 ⁇ 1 °C in 700 ml of the surface active agent test solution of a 0.05 wt% concentration contained in the apparatus as shown in the attached Figure 1.
  • Each slide glass having been subjected to cleansing as above was dipped in water for rinsing at the same temperature for 1 minute.
  • the rinsed slide glasses were air-dried for overnight, after which it was submitted to the evaluation.
  • Each set of 6 slide glasses dried as above was weighed to obtain its weight (W 3 ).
  • the cleansing rate was determined according to the following equation.
  • Triglyceride (rapeseed oil) was added to the aqueous solution with prescribed concentration of the detergents, (3 wt% as surface active agents) and the mixture was left over at 25 °C until the solubility equilibrium was obtained, upon which the interfacial tension between the cleansing liquid and rapeseed oil was measured by the Spinning Drop type tester [SPD-100, Produce of Miyamoto Manufacturing Co.]
  • the mixture of beef tallow and rapeseed oil (weight ratio 9/1 ) was used as a stain specimen, which was heated and fluidized at a temperature of above the melting points of oils and coated on a stainless plate (150 x 200 mm) using a barcorder in the amount such that the thickness of the stain after drying may be 20 ⁇ 3 u .
  • test specimen prepared according to (1) above was connected to the oscilloscope as shown in Figure 2, onto which a 0.05 ml drop of the test detergent liquid (0.05 wt% as the surface active agent) at the point A of Figure 2.
