AISHFLOC L precipitant is a cationic color removal aid in liquid form developed as a processing aid for use in phosphatation refineries.

AISHFLOC L precipitant is simple to use and can increase decolorization without increasing capital cost. AISHFLOC L precipitant can be used straight from the containing drum using a small dosing pump thereby reducing the requirement for expensive or complicated equipment. AISHFLOC L precipitant is of low order toxicity and meets FDA requirements when used according to our recommendations. 

AISHFLOC L precipitant was specifically developed for use in refineries which use phosphatation and therefore can be used in place of our traditional AISHFLOC L precipitant. AISHFLOC L precipitant has the advantage of being easier to handle than a conventional AISHFLOC precipitant. Fluctuations in raw sugar color are a serious problem in refineries with only filtration and the great advantage of using AISHFLOC L precipitant in this case is that it allows these refineries to operate efficiently with variable quality raw sugar. Reduced color loading on subsequent decolorization stages has made the permanent use of AISHFLOC L precipitant an attractive proposition. Carbon or Ion Exchange resin cycles can be extended resulting in substantial savings in operating costs.

AISHFLOC L precipitant is used in refineries throughout the world and is achieving excellent results.


When using AISHFLOC L precipitant, up to 50% lower color is obtained after phosphatation. Obviously, actual performance depends on the color and properties of the liquor before treatment. 

  • AISHFLOC L precipitant is extremely easy and convenient to use since it is a liquid product. 
  • Using AISHFLOC L precipitant means a very low capital outlay with appreciable increase in decolorization. 
  • AISHFLOC L precipitant contains no iso-propyl alcohol therefore making it more convenient to transport. 
  • No detectable residue of AISHFLOC L precipitant remains in the final product. 
  • AISHFLOC L precipitant is manufactured to the highest quality expected of Aishwaryaa and meets FDA requirements. As with all our products, AISHFLOC L precipitant is supplied with full technical back-up service from Aishwaryaa,


AISHFLOC L precipitant is usually added directly to the phosphatation feed stream, on the suction side of the reactor feed pump. It can be used straight from the containing drum using only a small dosing pump. Optimum dose rates range between 100 ppm and 300 ppm on sugar solids.The graph provided illustrates the decolorization achievable with AISHfloc L precipitant at various dose rates on a laboratory scale. At 300 ppm AISHFLOC L precipitant achieved 53% decolorization vs. a feed color of 1078 ICU’s.

Laboratory samples are readily available by contacting Aishwaryaa.

AISHFLOC L precipitant has a low order of toxicity. The acute oral (rat) LD50 value was determined to be 4.67 g/kg, No eye irritation was produced when tested. No skin irritation or sensitization was produced during repeat insult patch test using human subjects.  


AISHFLOC L precipitant should be stored in a dry, clean environment away from direct sunlight and prefer‑ ably at a temperature above 5°C and below 40°C. Fiberglass, stainless steel, polyethylene or polypropylene  are recommended for storage tanks. Mild steel, cast iron, aluminium or zinc are to be avoided as AISHFLOC L precipitant in its neat state is moderately corrosive towards these materials.


AISHFLOC L precipitant is packed in 240 kg net high density polyethylene drums. It is also available in bulk containers 1000 kg net 1090 kg gross.
