Description
The prescription teacher of dish washing detergent compositions is faced with and will obtains a kind of challenge of satisfying the prescription that requires with many different human consumer's correlated performances.
At first, when this composition is used for the wash up method, should be effective for the dirt that gets on from dirty " tableware ".Terminology used here " tableware " has general meaning, comprises any article that can see in wash up load vessel basically, comprises porcelain, glassware, plastic ware, holloware and cutter, comprises silverware.
The dirt of being run in wash up mainly is the dirt based on food, but does not get rid of other dirt.The dirt removed of the difficulty dark colour dirt that comprises unctuousness dirt, empyreumatic food soil, exsiccant food soil, produce by for example dark colour vegetables such as beet tails and tomato especially, and non-food soil, as steeping at the lipstick on the glass cylinder edge or as the Nicotine on the plate of ashtray.
The detergent for washing dishware with hand composition does not have washing assistant usually, and can contain the Ca and the Mg of the additional content that helps cleaning performance.Laundry and automatic dishwashing compositions generally contain high-load washing assistant.And the hard surface cleaner composition does not contain washing assistant sometimes, does not generally contain the additional Ca or the Mg of synergism yet.
The detergent for washing dishware with hand composition does not generally contain the bleaching component, and phase Antibleaching component is a laundry usefulness, the machine wash up is used and the common component of hard surface cleaning usefulness composition.
Manual dishwashing generally is formulated near neutral pH the time functional with detergent composition.The composition that the machine wash up is used, the hard-surface cleaning composition and the laundry composition that do not contain SYNTHETIC OPTICAL WHITNER generally are alkaline, have pH and are generally 9-11.The hard surface cleaner composition that contains SYNTHETIC OPTICAL WHITNER is tart normally, has pH and is lower than 6.
In manual dishwashing, use many different washing methodss usually.Preference to the method used has often reflected the geography and the culture background of cleaning the people.
A kind of traditional approach, for example see in Northern Europe usually, comprise that it generally is to be contained in the diluting soln of the dish washing detergent compositions in the rinse bath that the tableware of dirt is immersed, then with the surface of cloth or sponge brush tableware to remove dirt, then tableware is put into washing soln.
Another kind of traditional approach, the method of promptly directly using, usually see in southern Europe and Latin America, generally comprise the tableware of wetting dirt, from water-bath, take out every tableware then also with the cloth in the concentrated cleaning product that is soaked basically or the surface of sponge brush tableware, then tableware is immersed in another water-bath or be placed on and carry out rinsing in the flowing water flow.
Also have a kind of traditional approach (not being normally used) of manual dishwashing to comprise that the tableware with dirt contacts (for example using atomizer) with the concentrated cleaning product, and allow the concentrated cleaning product on the surface of tableware, keep for some time.Then tableware can be immersed in the water-bath or and carry out rinsing, can perhaps use the rinse cycle step rinsing tableware of automatic dishwashing machine randomly with for example sponge or the manual surface of wiping tableware of cloth simultaneously through under the flowing water flow.On the other hand, can be with tableware through also using the washing step of Betengent product, the washing methods that it can comprise the manual dishwashing method or use the automatic dishwashing machine.
The applicant has now found that the composition that contains anion surfactant and divalent cation (especially Ca or Mg) with acid pH has tangible feature performance benefit when being used for the wash up method, especially remove the oily feature performance benefit, in said wash up method, in fact spissated Betengent product directly is applied on the surface of tableware, preferably follows the rinsing tableware.
