being sticky and 10 being not sticky . 7 . rinse fore - arm with 50 ml of water in a beaker ( pre heated to 40 ° c .) and pat dry three times with a paper towel and wait for 2 mins . then assess skin for sticky and not sticky on a 0 - 10 scale ; 0 being sticky / greasy and 10 being not sticky and for rough and smooth on a 0 - 10 scale of 0 being rough and 10 smooth . 8 . identify preferred product . 9 . after 10 mins reassess the skin , which product results in softer skin . 1 . sanitize all equipment 2 . turn on water bath / vessel jacket to 85 ° c . 3 . add lipophilic structurants ( cetyl alcohol , multiwax 180mh , dc580 silicone wax ) and stir with overhead stirrer until completely melted 4 . add liquid phase ingredients ( petrolatum , dc200 , mineral oil , isopropyl isostearate ) and mix until fully liquid 5 . cool and pour mixture into a mould or container 6 . for sensory testing , mould chemistry onto razor analogue and attach to razor handle . chemistry to be of a suitable size for use in shaving ( 33mm long × 3mm wide ) test panel participants n = 1 - 5 were tested in accordance with the sensory protocol described above . as can be seen from the data all the test participants preferred the inventive example versus the comparative sample , demonstrating the advantage for the inclusion of silwet ®; all of the panelists preferred the inventive example for glide ; 2 out of 5 had a preference for the inventive example for lubrication on first non - overlapping strokes and ; all panelists preferred the inventive example for lubrication on over - strokes . neither formulation was found to be sticky after rinsing . the inventive sample was preferred for being soft after drying . inventive examples c and d were prepared as for inventive example b described above and tested according to the sensory protocol described above . as can be seen from the data there was no preference for one inventive example versus the other inventive example across the test participants . this demonstrates that the two polyether copolymer materials ( silwets ) used provide similar performance comparative example e which is presentative of the prior art comprising a modifying surfactant and a hydrophobic phase was prepared in accordance with the making instructions disclosed in wo2012 / 148939 ; example 1 . inventive example f was prepared in accordance with the making instructions as for inventive example b . comparative example e and inventive example f were tested according to the sensory testing protocol described above . as can be seen from the data all the test participants preferred the inventive example versus the prior art example ; all of the panellists preferred the inventive example for glide , 4 out of 5 had a preference for the inventive example for lubrication on first non - overlapping strokes ; all panellists preferred the inventive example for lubrication on over - strokes . neither formulation was found to be sticky after rinsing . inventive examples g - k were prepared in accordance with the making instructions as for inventive example b . the dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited . instead , unless otherwise specified , each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value . for example , a dimension disclosed as “ 40 mm ” is intended to mean “ about 40 mm ”. every document cited herein , including any cross referenced or related patent or application , is
