Formulation and Evaluation of Herbal Antidandruff Shampoo ...

International Journal of Pharma Research & Review, Oct 2013; 2(10):12-24ViscosityThe viscosity of herbal antidandruffshampoo was found to be 1010-1710 cpsand better result was 1599 cps shown ontable no:10pH test:The pH of herbal antidandruff shampoo wasfound to be 3.6-7.2 and better result was 6.6shown on table no 10SpreadibilityThe spreadibility of herbal antidandruffshampoo was found to be 46.4% and53.1%and shown on table no 10Calculation:1. Determining percent spread by weight:Firstly the dry filter paper was weighed andeliminates any variables like liquid,viscosity or evaporative rate%spread by weight= [(w1-w2)/w1]*100W1=3.252W2=1.74= (3.252-1.74)/3.252*100=1.512/3.252*100=0.464*100=46.4%2. Determining percent spread by area:This method is not exact as weighed method. To determining percent spread by area,Calculate as follows: A1=πr 2=3.14*9.6*9.6=289.38A2=3.14*7**7=153.86%spread by area=(A2/A1)/100=(153.86/289.38)*100=0.531*100=53.1%Foamability test:The Foamability of formulation was found to be 157 ml and shown on table no 10Calculation: -V1=209 MlAfter 5 Minutes V1 =148V2 = 50 Ml=V1-V2=207-50=157mlTable 10: Viscosity, pH, Foaming Property and SpreadibilityS.NO BATCHES VISCOSITY(cps) pH FOAMINGPROPERTY1 SH-SLNs 1 1010cps 3.72 SH-SLNs 2 1040cps 4.63 SH-SLNs 3 1210cps 5.34 SH-SLNs 4 1430cps 5.6 157ml5 SH-SLNs 5 1599 cps 6.66 SH-SLNs 6 1610cps 6.47 SH-SLNs 7 1640cps 6.58 SH-SLNs 8 1690cps 6.89 SH-SLNs 9 1710cps 7.2SPREADIBILITY%spread byweight=46.4%Spread byarea=53.1%Neeta Rai et.al, IJPRR 2013; 2(10) 21
