Description

EXAMPLE 1

[0074] The following compositions were prepared for the comparative tests.

TABLE-US-00001 % active matter A B C Polyquaternium 37 0.8 0.8 0.8 C12-13 Pareth-9 0.5 0.5 PPG-3 Caprylyl ether 1.0 Bis (Hydroxy/Methoxy) Amodimethicone 0.5 Citric acid q.s. to pH 4.0 Water to100

[0075] The compositions B and C are within the scope of the claim 1.

[0076] Human hair streaks having approximately 25 cm length and weighing approximately 3.5 g were used for the comparative tests. The streaks were damaged prior to the tests by means of double bleaching with a bleaching composition commercially available under the brand name Goldwell.

[0077] The streaks, always in duplicate, were treated with the above compositions. Therefore, each streak was applied approximately 1 g of the product and left on the streak for 15 min and the streaks were rinsed off with water. Afterwards only one of the streaks of each pair was dried with a hair drier. Hair temperature reached was approximately 95 C. The temperature measurement was carried out using an infrared measuring device from a distance of approximately 5 cm.

[0078] Additionally two hair streaks were treated with composition C and the one was heated using hair drier to a temperature of 95 C. without rinsing off the composition (C+* in the Table below) and the other was treated with an hot iron operated at 130 C. for 5 times which resulted in approximate hair temperature of 100 C. (C+** in the Table below).

[0079] The suppleness of the hair was measured with a zwick machine and expressed as the force (in milliNewtonmN) to pull a streak through the rods of the machine. The machine is commercially available from Zwick/Roell Company and includes a manual. It was used according to its manual. Briefly, the streak was places among 5 metal rods which were placed offset in a given distance horizontally (2 cm) and vertically (8 cm) and the force needed to pull the streaks through the metal rods at a given rate (5 cm/min) was measured. All values reported in the Table below are average of at least 6 readings.

[0080] In order to test the long lastingness of hair suppleness, the hair streaks were washed 5 times first and the suppleness was measured again as described above and after 5 additional washes the measurements were repeated. For washing hair streaks, 5% by weight Sodium lauryl ether sulfate solution in water at pH 5.0 was used.

[0081] The following results were obtained.

TABLE-US-00002 Suppleness (mN) Composition Heat Start 5 Wash 10 Wash Water 1741 2072 1938 A + 756 873 1023 A 791 1145 1578 B + 697 809 798 B 715 1046 1311 C + 450 515 659 C 525 1020 1280 C +* 348 518 629 C +** 388 489 572

[0082] It should be noted that the lower the value, the higher the suppleness of the hair.

[0083] From the above results it is clear that the aqueous composition according to the present invention improves hair suppleness and this effect is long lasting especially when hair temperature is increased after application of the composition. It is also beyond any doubt that addition of nonionic surfactant to the Polyqautemium-37 comprising composition improved additionally the suppleness of the hair. It was observed that the suppleness was affected by the presence of additional substances, but the streaks treated with the composition of the present invention were judged to have enough suppleness.

[0084] The above results prove beyond any doubt the improved suppleness of the hair treated with the aqueous composition of the present invention.

[0085] The following examples fall within the scope of the present invention.
