  • the pack can also comprise means for controlling the relative dispensing rate of the two or more products from the storage means.
  • the pack preferably comprises an organic solvent composition and an automatic dishwashing detergent composition and is used for removing cooked-, baked-, and burnt-on food soil from cookware and tableware.
  • the two or more automatic dishwashing detergent or auxiliary products are in rheology-matched gel-form.
  • Compositions are considered to be rheology-matched if they have similar yield values (differing by less than about 50%, preferably by less than about 20%) and/or similar viscosities (differing by less than about 50%, preferably by less than about 20%) under the same shear conditions.
  • compositions comprising the herein defined solvent systems for direct application to burnt-on and baked-on food soiled cookware and tableware.
  • compositions comprising an organic solvent system having a liquid surface tension of less than about 27 mN/m.
  • Preferred compositions contain from about 1% to about 99% preferably from about 5% to about 50% of organic solvent as herein defined, highly preferred being a mixed solvent system based on alkanolamine and a mixed glycol ether solvent system as described hereinabove.
  • the method for determining contact angle is as follows.
  • a sample plate (prepared as described below) is dipped into and pulled out of a liquid and contact angles calculated after Wilhelmy Method.
  • the force exerted on the sample according to the immersion depth is measured (using a Kruss K12 tensiometer and System K121 software) and is proportional to the contact angle of the liquid on the solid surface.
  • the sample plate is prepared as follows: Spray 30-50 grams of Canola Oil into a beaker. Dip a glass slide (3x9x0.1 cm) into the Oil and thoroughly coat the surface. This results in an evenly dispersed layer of oil on the surface. Adjust the weight of product on the slide's surface until approximately 0.5 g of oil has been delivered and evenly distributed. At this point, bake the slides at 450F for 20 minutes, and allow to cool to room temperature.
  • the product preferably has a viscosity from about 0.1 to about 200 Pa s, preferably from about 0.3 to about 20 Pa s as measured with a Brookfield cylinder viscometer (model LVDII) using 10 ml sample, a spindle S-31 and a speed of 3 rpm. Rheology is measured under ambient temperature conditions (25° C).
  • Preferred polyhydric alcohols used to produce carboxyvinyl polymers include polyols selected from the class consisting of oligosaccarides, reduced derivatives thereof in which the carbonyl group is converted to an alcohol group, an pentaerythritol; most preferred is sucrose or pentaerythritol. It is preferred that the hydroxyl groups of the modified polyol be etherified with alkyl groups, the polyol having at least two allyl ether groups per polyol molecule. When the polyol is sucrose, it is preferred that the sucrose have at least about five allyl ether groups per sucrose molecule. It is preferred that the polyether of the polyol comprise from about 0.1% to about 4% of the total monomers, more preferably from about 0.2% to about 2.5%.
  • Preferred monomeric olefinically unsaturated carboxylic acids for use in producing carboxyvinyl polymers used herein include monomeric, polymerizable, alpha-beta monoolefinically unsaturated lower aliphatic carboxylic acids; more preferred are monomeric monoolefinic acrylic acids of the structure:
  • Carbopol® Various carboxyvinyl polymers, homopolymers and copolymers are commercially available from B. F. Goodrich Company, New York, N.Y., under the trade name Carbopol®. These polymers are also known as carbomers or polyacrylic acids.
  • Carboxyvinyl polymers useful in formulations of the present invention include Carbopol 910 having a molecular weight of about 750,000, Carbopol 941 having a molecular weight of about 1 ,250,000, and Carbopols 934 and 940 having molecular weights of about 3,000,000 and 4,000,000, respectively. More preferred are the series of Carbopols which use ethyl acetate and cyclohexane in the manufacturing process, Carbopol 981 , 2984, 980, and 1382.
  • the cellulosic type thickeners hydroxyethyl and hydroxymethyl cellulose (ETHOCEL and METHOCEL® available from Dew Chemical) can also be used.
  • the present invention envisages the use of solvent compositions as additives for conventional automatic dishwashing detergent compositions. It also envisages multi-component dishwashing products containing purpose-designated combination of solvent compositions and dishwashing detergent compositions. The invention also envisages so called "all-in-one" detergent and hard surface cleaning products having both an alkaline detergent and a solvent functionality. In the case of additive and multi-component products, the invention does not require the two compositions to be in the same physical form.
  • the organic solvent composition can be in any physical form, e.g. liquid, paste, cream, gel, powder, granules or tablets and similarly the automatic dishwashing detergent composition can be in any of these forms.

  • Bleaching agent Bleaching agents suitable herein include chlorine and oxygen bleaches, especially inorganic perhydrate salts such as sodium perborate mono-and tetrahydrates and sodium percarbonate optionally coated to provide controlled rate of release (see, for example, GB-A-1466799 on sulfate/carbonate coatings), preformed organic peroxyacids and mixtures thereof with organic peroxyacid bleach precursors and/or transition metal-containing bleach catalysts (especially manganese or cobalt).
  • Inorganic perhydrate salts are typically incorporated at levels in the range from about 1% to about 40% by weight, preferably from about 2% to about 30% by weight and more preferably from abut 5% to about 25% by weight of composition.
  • the suds suppressers suitable for use herein include nonionic surfactants having a low cloud point.
  • Cloud point is a well known property of nonionic surfactants which is the result of the surfactant becoming less soluble with increasing temperature, the temperature at which the appearance of a second phase is observable is referred to as the “cloud point” (See Kirk Othmer, pp. 360-362).
  • a “low cloud point” nonionic surfactant is defined as a nonionic surfactant system ingredient having a cloud point of less than 30° C, preferably less than about 20° C, and even more preferably less than about 10° C, and most preferably less than about 7.5° C.
