(54)SHINE ENHANCING SPRAY COMPOSITION


(57) The present invention relates to a substantially anhydrous shine enhancing spray composition for keratin fibers, especially for human hair, comprising, in a cosmetically acceptable medium, one or more hair setting film forming polymers and a pyrrolidone carboxylic acid ester.


Description


[0001] The present invention relates to a substantially anhydrous shine enhancing spray composition for keratin fibers, especially for human hair, comprising, in a cosmetically acceptable medium, one or more hair setting film forming polymers and a pyrrolidone carboxylic acid ester.

[0002] Substantially anhydrous compositions applied by spraying onto keratin fibers and especially hair have been used for setting said fibers to a certain shape for many years. They are based on a non-aqueous solvent and comprising at least one hair setting /film forming polymer. In order to realize certain flexibility to the formed film on the keratin fiber surface, usually surfactants, polyols, oils especially silicone oils are added. However, addition of these substances influences performance of the composition and causes reducing of the setting effect. Generally, it is known that the sprays used for setting hair do take away some of the natural hair shine so that the hair appears less shiny, and has therefore dull appearance. There is a great need for products providing shine and hair setting to keep the hair in desired shape and hold in the shape for a considerable period of time.

[0003] The present invention starts from the above known problems with the performance of the sprays, and aims at providing a spray composition which does not affect hair setting negatively and additionally enhances hair shine.

[0004] Pyrrolidone carboxylic acid and its esters are known in hair conditioners and being used for improving several hair properties. EP 2090291 discloses aqueous hair conditioning compositions comprising PCA and/or its salts, one or more PCA ester and a hair conditioning compound selected from quaternary ammonium polymers and surfactants. The document does not address any substantially anhydrous compositions.

[0005] The inventors of the present invention have unexpectedly found out that a substantially anhydrous composition comprising one or more pyrrolidone carboxylic acid ester and one or more hair setting film forming polymers does provide good hair setting and additionally provides hair additional shine. It is usually the case that the compounds added into to the substantially anhydrous compositions take away part of hair setting effect and do result in less shiny hair. The inventors of the present invention have observed the opposite effects when the substantially anhydrous hair setting composition is added pyrrolidone carboxylic acid ester.

[0006] Accordingly, the first object of the present invention is a substantially anhydrous composition for keratin fibers, especially for human hair, comprising, in a cosmetically acceptable substantially anhydrous medium, one or more hair setting film forming polymers and one or more pyrrolidone carboxylic acid ester according to general structure

wherein R1 is a straight or branched, saturated or unsaturated alkyl chain with 1 to 22 C atoms, phenyl, phenyl alkyl with alkyl chain length of 1 to 4 C atoms, phenyl alkoxy group with alkyl chain length of 1 to 4 C atoms and phenoxy alkyl group with alkyl chain length of 1 to 4 C atoms.

[0007] The second object of the present invention is the use of the compositions for providing keratin fibers, especially human hair setting, hold and shine.

[0008] Then third object is the method of setting and shine enhancing keratin fibers, especially human hair wherein the dry hair is applied the composition of the present invention, preferably by spraying.

[0009] The fourth object is a kit for keratin fibers, especially human hair comprising the composition of the present invention.

[0049] The composition A is according to the present invention and the other compositions B to E are comparative examples.

n-pentane 20.0
Hydrofluorocarbon 152a 60.0


[0051] 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.

[0052] 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.

[0053] 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.

[0054] The shine factor was calculated with the Reich Robins method.

[0055] The following results were obtained
CompositionBending force (mN)Shine 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


[0056] 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.

[0057] 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.

[0058] The results obtained with the individual compounds do not provide any indication to predict the combined effect.
