Synthetic milk is prepared by mixing urea, caustic soda, cheap cooking oil and common detergents. Detergents are added to emulsify and dissolve the oil in water giving the frothy solution, the characteristic white colour of milk. Refined oil is used as a substitute for milk fat. Caustic soda is added to the blended milk to neutralize the acidity, thereby preventing it from turning sour during transport. Urea are added for solid-not-fat (SNF).  Since its taste is disgusting , it is blended with natural milk ( whose taste is also disgusting but less so) The cost of preparing synthetic milk is Rs. 5 per litre and it is sold for upto Rs 30  per litre. Other adulterants are industrial starch, glucose, pond water and sugar.Synthetic milk is not milk but an entirely different factory made substancehttp://www.bihartimes.in/maneka/The_Technology_of_Synthetic_Milk.html
