BMC Biotechnology

Table 1 Mild Shampoo composition - enzymatic hydrolysates from chicken feathers

Components	% (P/P)
Sodium lauryl sulfate	30
Decyl polyglucose	5
Laureth Decyl polyglucose	5
Surfax acid	3
Coconut fatty acid diethanolamide	4
Phenochem or Phenova	0.5
Germall 115	0.2
Keratin hydrolysate	10
Unistab 569	0.2
Essence of anise	0.5
Distilled water qs	100 ml

The Germall requires previous heating (80°C) until complete dissolution in distilled water. After this procedure all the other components were added to the solution. However the polyglucose must also be heated before incorporation into the solution. The mixtures should be homogenized slowly to avoid foaming. The last components to be added were the enzymatic hydrolysate from feathers, the Unistab 569 and the essence.
