Description

EXAMPLE 1

[0050] The following compositions were prepared.

TABLE-US-00001 % by weight A B C D E Acrylates/Octylacrylamide Copolymer 20 20 — 20 — Aminomethylpropanol 5 5 — 5 — Octyldodecyl PCA 15 — 15 — — Dimethicone — — — 15 15 Ethanol q.s. to 100 % by weight A B C D E Acrylates/Octylacrylamide Copolymer 20 20 — 20 — Octyldodecyl PCA 15 — 15 — — Dimethicone — — — 15 15 Ethanol q.s. to 100

[0051] The composition A is according to the present invention and the other compositions B to E are comparative examples.

[0052] The compositions were filled into an aerosol can as follows:

TABLE-US-00002 % by weight The solution of Example 1 20.0 n-pentane 20.0 Hydrofluorocarbon 152a 60.0

[0053] For this purpose, the hair streak weighing approximately 2 g was washed first with a commercially available cleansing composition and dried with a hair dryer. The dry hair was applied the aerosol compositions above onto hair at a composition to hair weight ratio of 1:2 The hair steaks were left to dry in the air and the bending force and the shine were measured as disclosed below.

[0054] The bending force of the hair was measured with a zwick machine and expressed as the force (in milliNewton—mN). The machine measured the force needed to push down the streak between two rods. The machine is commercially available from Zwick/Roell Company and includes a manual. It was used according to its manual.

[0055] The shine measurement was carried out with the Samba Hair System from Bosa Nova Technologies via polarized illumination. The hair tress was illuminated and the specular reflection was measured. This gives information about the gloss of the hair.

[0056] The shine factor was calculated with the Reich Robins method.

[0057] The following results were obtained

TABLE-US-00003 Bending Shine Composition force (mN) Factor A 0.62 30.45 B 0.48 11.32 C 0.14 17.50 D 0.29 22.49 E 0.09 15.60

[0058] It should be noted, for the bending force, the higher the number, the higher the hold of the style. For the shine factor, in the same way, the higher the number, the higher the shine.

[0059] From the above results, it is beyond any doubt that the composition according to the present invention has the highest score in bending force, indicating clearly the best hold and the highest score in shine factor indicating the best shine. It must be pointed out that silicones are known to enhance shine of hair; however, they even failed to enhance shine as good as the inventive composition. Furthermore, the bending force of the polymer film is reduced dramatically in the presence of dimethicone, however, presence of PCA ester increased the bending force showing clearly the better hold.

[0060] The results obtained with the individual compounds do not provide any indication to predict the combined effect.
