GrowLec 55 is a fine modified lecithin with various applications in animal nutrition. Use of standard lecithin hinders absorption of fat and fat soluble vitamins. To overcome these problems, a product is  required which has higher polarity. This could be obtained by hydrolyzing standard lecithin. More hydrolysis of lecithin will not serve the purpose. Standard lecithin which is enzymatic  hydrolyzed by highly technical process, gives consistent and desired end results. GrowLec FL is such a unique product  containing lysophosphatidyl choline having hlb value 8-12 with more polar nature and hence highly soluble in water.
