Definitions
- the present invention relates to liquid or gel type automatic dishwashing detergent compositions. More particularly, the invention relates to a process of imparting transparency or translucency to a liquid or gel type automatic dishwashing detergent product and a transparent or translucent a liquid or gel type automatic dishwashing detergent product having one or more potassium sources to maintain pre-selected potassium sodium ratios in order to make the composition transparent or translucent while at the same time not using any (I) potassium tripolyphosphate or (n) mixtures of sodium and potassium tripolyphosphate.
- a transparent or translucent product allows for suspension of colored prills into that product, which can further enhance the physical appearance of the product
- the transparent product may be clear, or dyed, using dyes that do not cause significant staining or dyeing of plastics du ⁇ ng the wash cycle in automatic dishwashing.
- the inventors of the present invention have discovered that by maintaining a K:Na weight ratio greater than at least about 0.5: 1, K:Na, outstanding translucent characteristics can be imparted without having to use KTPP or SKTPP.
- high phosphate levels can be attained by the addition of sodium t ⁇ polyphosphate (STPP) alone, along with the addition of potassium hydroxide (KOH) for obtaining high alkalinity or the addition of other sources of potassium for obtaining moderate alkalinity.
- STPP sodium t ⁇ polyphosphate
- KOH potassium hydroxide
- the present invention is thus directed to overcome one or more of the problems as set forth before.
- the invention meets the needs above by providing a process of imparting transparency or translucency to a liquid or gel type automatic dishwashing detergent product, and a transparent or translucent a liquid or gel type automatic dishwashing detergent product.
- the process of imparting transparency or translucency to a liquid or gel type automatic dishwashing detergent product comp ⁇ ses the steps of providing a liquid or gel type automatic dishwashing detergent composition expressly free from (l) potassium t ⁇ polyphosphate and (n) mixture of sodium tripolyphosphate and potassium tripolyphosphate, adding one or more of potassium sources to the liquid or gel type automatic dishwashing detergent composition, the potassium sources being expressly free of potassium t ⁇ polyphosphate, and maintaining a potassium: sodium weight ratio greater than at least about 0.5:1.
- the transparent or translucent a liquid or gel type automatic dishwashing detergent product comp ⁇ ses a liquid or gel type automatic dishwashing detergent composition.
- the composition is expressly free from (1) potassium tripolyphosphate and ( ⁇ ) mixture of sodium t ⁇ polyphosphate and potassium t ⁇ polyphosphate.
- the composition includes one or more of potassium sources, the potassium sources being expressly free of potassium t ⁇ polyphosphate.
- the potassium: sodium weight ratio is greater than at least about 0.5:1
- the process of imparting transparency or translucency to a liquid or gel type automatic dishwashing detergent product comp ⁇ ses the steps of providing a liquid or gel type automatic dishwashing detergent composition expressly free from KTPP and SKTPP.
- KTPP as used herein means potassium tripolyphosphate, as is commercially available, which may contain incidental and/or trace impurities of other t ⁇ polyphosphates, such as STPP.
- SKTPP as used herein means commercially available mixtures of STPP and KTPP, wherein the weight ratio of Na;K is more than 95:5. Potassium sources
- the process further includes the step of adding one or more of potassium sources to the liquid or gel type automatic dishwashing detergent composition, the potassium sources being expressly free of potassium tripolyphosphate.
- the potassium source is KOH, added m an amount desirably in a range of from about 4% to about
- the liquid or gel type automatic dishwashing detergent composition has a pH desirably of at least about 9, and preferably, in a range of from about 11 to about 12.5.
- pH desirably of at least about 9, and preferably, in a range of from about 11 to about 12.5.
- the term pH means pH of a 1% solution of liquid ADW composition in water by weight.
- the potassium source is selected from the group consisting of K 2 S0 4 , KNO 3 , K 2 C0 3 , KC1, KBr, K 3 PO 4 , potassium silicate, potassium acetate, or mixtures thereof.
- the potassium source When the potassium source is selected from the aforementioned group, it is added in an amount desirably in a range of from about 2% to about 20% by weight of the detergent composition and preferably m a range of from about 5% to about 16% by weight of the detergent composition, depending upon the availability of K in the potassium source on a molar basis.
- the liquid or gel type automatic dishwashing detergent composition has a pH of at least about 6.5. The lower pH values are preferred when formulating the detergent composition with enzymes, which may be present m the hqui-gel composition m a liquid form or in the form of solid prills that are coated with a permeable or impermeable coating.
- K'Na weight ratio K'Na weight ratio
- the process further includes the step of maintaining a potassium: sodium weight ratio desirably greater than about 0.5 1 , and preferably above 0 65.1.
- the K.Na weight ratio is desirably maintained in a range of from about 0.5: 1 to about 1.25 T , particularly when the detergent composition has a total solids content of less than about 20% by weight.
- the potassium: sodium weight ratio is maintained at least greater than 0.75: 1, and more preferably, in a range of from about 0.75.1 to about 2 1, potassium: sodium, particularly when the liquid or gel type automatic dishwashing detergent composition has a total solids content in a range of from about 20% to about 40% by weight
- the total solids content comp ⁇ ses solids in the form of STPP, I e , the phosphate builder, which is typically present in an amount in a range of about 10%) to 40%, thickener, such as a polymer, and potassium hydroxide, i.e., one of the potassium sources It should be noted that other optional ingredients may also make up the total solids content in a hqui-gel ADW composition.
- Phosphate Builder Phosphate Builder
- the liquid or gel type automatic dishwashing detergent composition provided in this process further includes a phosphate builder an amount desirably m a range of from about 10% to about 40% of said detergent composition, and preferably in a range of from about 12% to about 30% of said detergent composition.
- the preferred phosphate builder useful m practicing this invention is sodium t ⁇ polyphosphate (STPP)
- STPP sodium t ⁇ polyphosphate
- the STPP is essentially free of any KTPP, other than what may be present in trace quantities as naturally occur ⁇ ng lmpu ⁇ ty or an impurity du ⁇ ng the commercial manufacturing of STPP.
- Other phosphate builders known to those skilled in the art may also be utilized in lieu of or in conjunction with STPP.
- a transparent or translucent a liquid or gel type automatic dishwashing detergent product includes a liquid or gel type automatic dishwashing detergent composition.
- the composition is expressly free of KTPP and SKTPP.
- the composition includes one or more of potassium sources, the potassium sources being expressly free of KTPP.

- An example of a chlorine bleach stable surfactant is Dowfax® a onic surfactant available from the Dow Chemical Company.
- Enzymes may be present in the liqui-gel composition in the form of liquid enzymes when the pH of the liquid ADW is less than about 10.0 At pH's greater than about 10.0, enzymes in the form of solid prills that are coated with impermeable or permeable coating may be used.
- Various types of enzymes are well known to those skilled in the art, such as proteases and amylases, both of which are useful in carrying out this invention.
- the liquid automatic dishwashing detergent composition may optionally contain up to about 20% of a dispersant polymer selected from the group consisting of polyacrylates and polyacrylate copolymers.
- Samples A, B and C of the liquid automatic dishwashing detergent product composition are formulated using the below named ingredients, as set forth in Example A.
- Protease enzyme 0.5 (liquid) 1.0 (prill) 1.0 (prill)
