5. Preparation of the <strong>Hair</strong> Swatches <strong>and</strong> Test Formulations<br />
For the sensory test on hair swatches these were damaged by bleaching (<strong>and</strong> perming) in a st<strong>and</strong>ardised way. Then st<strong>and</strong>ard<br />
aliquots of the conditioning agents were applied via a simple hair rinse <strong>for</strong>mulation, based on<br />
• 0.5 % emulsifier (Ceteareth-20 resp. Ceteareth-25)<br />
• 2.0 % Cetyl Alcohol<br />
• 1.0 or 2.0 % active of the tested conditioning agents (<strong>for</strong> combination 1.0 + 1.0 %)<br />
• ad 100.0 % water<br />
• pH ad 4.0 resp. 5.0<br />
“Control” indicates this <strong>for</strong>mulation with no conditioning agent.<br />
Since the ester quat VARISOFT ® EQ 65 Pellets was introduced to the market in 2007 after finalizing the comparison of the other<br />
conditioning agents, professional half head tests have been conducted separately to compare the conditioning properties against<br />
two st<strong>and</strong>ards: Cetrimonium Chloride <strong>and</strong> Behentrimonium Chloride. The tests have been done by an independent test institute<br />
with 10 panelists by applying <strong>for</strong>mulations based on:<br />
• 0.5 % emulsifier (Ceteareth-25)<br />
• 5.5 % Cetearyl Alcohol<br />
• 2.0 % active quat<br />
• ad 100.0 % water<br />
• pH ad 4.5<br />
