Embodiment 1
[0074] A leave-in shampoo according to the present invention was prepared. The compositions are shown in Table 1 (weight percent ranges are based on the total weight of the corresponding leave-in shampoo composition).
[0075] Table 1: Composition of the leave-in shampoo mousse of the present invention
[0076]
[0077] When dispensed, the mousse according to the composition of Table 1 above has about 0.1 to 0.2 g / cm 3 Density. When applied to leave-in hair, the lather goes from wet to leave-in quickly and leaves no residue.
Embodiment 2
[0079] The dry combing power of hair treated with the foam according to Example 1 above was evaluated relative to the dry combing power of control treated tresses. The main technical function of many conditioning products is to lubricate the hair surface and thereby contribute to manageability and smoothness and reduce combing friction. A common and highly consumer-relevant method of measuring this lubrication involves the instrumented combing experiment. The test involved using an Instron Tensile Tester to measure the frictional force when pulling a lock of hair through a comb.
[0080] Eight (8) European medium brown hair tresses (supplied by International Hair Importers) (3.0 g, 8 inches long, 1 inch wide) were used per treatment group. Prior to treatment, the tresses were bleached for a total of 40 minutes using a standard bleaching program with a 6% hydrogen peroxide solution at pH 10.2 and 40°C.
[0081] The tresses were normalized by treating all tresses with 15% by w...
Embodiment 3
[0089] The performance of the leave-in shampoo composition according to Example 1 above was evaluated with respect to the shine effect on treated hair. The increase in shine of sebum-treated hair resulting from the application of the Example leave-in shampoos was measured as described below.
[0090] Eight (8) European medium brown hair tresses (supplied by International Hair Importer) (3.0 g, 8 inches long, 1 inch wide) were used per treatment group. Prior to treatment, the tresses were bleached for a total of 40 minutes using a standard bleaching program with a 6% hydrogen peroxide solution at pH 10.2 and 40°C.
[0091] The tresses were normalized by treating all tresses with 15% by weight sodium lauryl ether sulfate (SLES), applying 15% SLES at 30% of the weight of the tresses to wet hair, massaging for 30 seconds, and rinsing for 30 seconds (40°C, 1GPM flow rate). The tresses were dried overnight at 60% relative humidity and ambient temperature.
[0092]Each tress was t...
