Kemphos 2001 - Typical Applications and Suggested Product Formulas

  • Dishwashing Detergents

  • Cleaners , Cleaners & Sanitizers

  • Scouring Powders


Dishwashing Detergents

Machine dishwashing detergents

Kemphos 2001 is being used in machine dishwashing detergents for home and for industrial and
institutional (I&I) purposes.

The Chlorine contributes to the overall cleaning power of the detergent by oxidizing proteinaceous soil. The phosphate contributes towards shiny dishes and reduces spotting on glassware. Phosphates also control water hardness and enhance detergency.

Most dishwashing detergents also contain silicates which provide alkalinity, soil suspension, prevent metal corrosion and filming of glassware.Surfactants provide detergency and control foaming. Fillers such as Sodium Sulphate and Sodium Carbonate balance the formulation. Sodium Carbonate is generally used when additional alkalinity is required.

Household machine dishwashing detergents usually operate at lower pH and Chlorine levels than the I&I products. The level of available Chlorine in wash solutions is in the range of 15 to 20 ppm. The pH level of the solution should be above 10 to maintain adequate detergency, but less than 11 to guard against a highly
caustic product.


Household automatic dishwasher detergent

Typical formulation:

Raw material Weight %
KEMPHOS 2001 25
Sodium metasilicate pentahydrate 12
Nonionic Surfactant (low foam) 3
Sodium Tripolyphosphate 45
Sodium Sulphate Up to 100%

 

Institutional Dishwasher Detergents

Typical high Alkaline Formulation:

Raw Material Weight %
KEMPHOS 2001 35-25
Sodium Carbonate 20-10
Sodium Hydroxide 10-15
Sodium Methasilicate 20-10
Sodium tripolyphosphate 15-40

Mixing is generally accomplished in a ribbon or tumbler. The order if mixing components be such that the nonionic surfactant is absorbed into the alkaline chemicals. Kemphos 2001 should be added last.


Cleaners, Cleaners & Sanitizers


General Purpose Cleaners

Alkaline heavy – duty cleaners are used for manual cleaning of open equipment.

Basic Typical Formulation:

Raw material Weight %
KEMPHOS 2001 30.0-25.0
Sodium Tripolyphosphate 30.0-20.0
Soda ash 10.0-5.0
Anionic Surfactant 5.0-3.0
Sodium chloride/Sodium Sulphate Up to 100%

Cleaners and sanitizers

Cleaners and sanitizers find useful applications in the food processing industry which includes dairies, breweries, meat packaging and soft drink manufacturers.

These products are also widely used in restaurants and cafeterias to wash equipment and surfaces used
for food preparation and food service. Hospitals, hotels, motels are large users of cleaning products.
The available Chlorine is effective against colour and stains and aids in the removal of proteinaceous soil.

Cleaners and Sanitizers based on Kemphos 2001 also contain Phosphates which are excellent builders suitable for most cleaning products. Trisodium Phosphate is used for alkalinity and buffering action,
precipitate builder.


Typical Formulations:

Raw material Weight %
KEMPHOS 2001 40
Sodium sulphate 35
Sodium carbonate 4.8
Anionic surfactant 20
Fragrance 0.2

 

Raw material Weight %
KEMPHOS 2001 30
Sodium tripolyphosphate 50
Sodium sulphate 17.2
Anionic surfactant 2.5
Fragrance 0.3

 

Notation: Cleaning and Sanitizing products contain varying amounts of available Chlorine, phosphates
and other components, depending on the applications for which they are formulated. The compositions
given are suggested only as a basic formulation.


Scouring Powders

Kemphos 2001 is used as a raw material in scouring powders which require both high buffered alkalinity
and a stable active Chlorine. Oil film, food and stains are oxidized by Chlorine to soluble components, which
can be rinsed off with water. The anionic surfactants contribute to detergency by wetting and foam suspending action. Silica or another abrasive ingredient provides the scouring action.


Typical Formulation:

Raw material Weight %
KEMPHOS 2001 70.0
Calcium carbonate
25.5
Nonionic surfactant 0.5
Anionic surfactant 3.5
Fragrance 0.5
