Abstract

The present disclosure concerns a cosmetic product for modifying the natural color of keratinous fibers, in particular human hair. The cosmetic product includes at least one packaging (VP) and a cosmetic composition (KM) contained in this packaging (VP). The packaging is made of a multi-layer film (F) including at least two polymer layers (P1) and (P2) and at least one barrier layer (BS). The cosmetic composition includes at least one oxidizing agent, at least one C 8 -C 30 alcohol, at least one specific anionic surfactant, at least one non-ionic surfactant and at least one acrylic-based thickening agent. The use of the packaging (VP) in combination with the cosmetic composition (KM) does surprisingly not lead to an inflation of the packaging or an excessive water loss of the agent (KM) during storage.

First claim

The invention claimed is:

1. A cosmetic product for modifying the natural color of keratinous fibers comprising
(i) at least one packaging comprising at least one multi-layer film comprising at least one first polymer layer, at least one second polymer layer and at least one barrier layer, and
(ii) at least one cosmetic composition packaged in the packaging and comprising:
a) at least one oxidizing compound,
b) at least one C 8 -C 30 alcohol,
c) at least one anionic surfactant selected from compounds of the formula R(OCH 2 CH 2 )n-OSO 3 -X + , wherein R represents saturated or unsaturated C 8 -C 30 alkyl radicals, n represents integers from 10 to 50 and X + represents a physiologically tolerable cation,
d) at least one non-ionic surfactant, and
e) at least one thickening agent selected from the group of copolymers of (meth)acrylic acid and (meth)acrylic esters, copolymers of (meth)acrylates and (meth)acrylamides, copolymers of hydroxyethyl (meth)acrylates and (meth)acrylamides, copolymers of (meth)acrylates, (meth)acrylamides and ethoxylated (meth)acrylic acid esters and mixtures thereof
wherein the first polymer layer is formed of polyethylene terephthalate or polyethylene naphthalate, the second polymer layer is formed of a polyolefin, and the barrier layer comprising metalized, oriented polypropylene that comprises a layer of metal disposed directly on a layer of oriented polypropylene, wherein a ratio of the layer thickness of metal to oriented polypropylene is from 1:1000 to 1.10.

2. The cosmetic product according to claim 1 , wherein the first polymer layer has a layer thickness of from about 4 μm to about 50 μm; the second polymer layer has a layer thickness of from about 20 μm to about 150 μm; and/or the barrier layer has a layer thickness of from about 4 μm to about 20 μm.

3. The cosmetic product according to claim 1 , wherein the multi-layer film has an Oxygen Transmission Rate at 23° C. and 50% relative humidity of from about 0.1 to 5 cc/m 2 /d/bar and has a water vapor permeability at 38° C. and 100% relative humidity of from about 0.1 to about 5 g/m 2 d.

4. The cosmetic product according to claim 1 , wherein the adhesive strength of the film is from about 0.1 to about 10 N/15 mm and/or wherein the seal strength of the packaging is from about 10 to about 40 N/15 mm under the conditions 150° C., 2.54 cm (1″) and 4 kg/cm 2 .

5. The cosmetic product according to claim 1 , wherein the at least one barrier layer is disposed between the at least one first polymer layer and the at least one second polymer layer.

6. The cosmetic product according to claim 1 , wherein the first polymer layer forms an outer layer of the at least one packaging.

7. The cosmetic product according to claim 1 , wherein the cosmetic composition has a pH value (measured at 20° C.) of from about 1.5 to about 5.0.

8. The cosmetic product according to claim 1 , wherein the cosmetic composition comprises the at least one oxidizing compound in a total amount from about 0.5 to about 20% by weight and/or wherein the cosmetic composition comprises the at least one C 8 -C 30 alcohol in a total amount from about 0.10 to about 7.0% by weight.

9. The cosmetic product according to claim 1 , wherein the cosmetic composition comprises the at least one thickening agent e) in a total amount from about 0.2 to about 6% by weight.

10. The cosmetic product according to claim 1 , wherein the anionic surfactant c) of the cosmetic composition is a sodium sulphate of a linear C 12 -C 14 alkyl ethoxylate with 30 ethylene oxide units per surfactant molecule, and/or the non-ionic surfactant d) of the cosmetic composition is a linear C 16 -C 18 ethoxylated alcohol with 20 ethylene oxide units per surfactant molecule.

11. The cosmetic product according to claim 1 , wherein the anionic surfactant c) of the cosmetic composition is a sodium sulphate of a linear C 12 -C 14 alkyl ethoxylate with 30 ethylene oxide units per surfactant molecule.

12. The cosmetic product according to claim 11 , wherein the sodium sulfate of a linear C 12 -C 14 alkyl ethoxylate having 30 ethylene oxide units per surfactant molecule is included in the cosmetic composition in an amount of 1 to 3% by weight, based on the total weight of the cosmetic composition.

13. The cosmetic product according to claim 1 , wherein the non-ionic surfactant d) of the cosmetic composition is a linear C 16 -C 18 ethoxylated alcohol with 20 ethylene oxide units per surfactant molecule.

14. The cosmetic product according to claim 13 , wherein the linear C 16 -C 18 ethoxylated alcohol with 20 ethylene oxide units per surfactant molecule is included in the cosmetic composition in an amount of from about 0.5 to about 2% by weight, based on the total weight of the cosmetic composition.

15. The cosmetic product according to claim 1 , wherein the first polymer layer (P1) has a layer thickness of from about 5 μm to about 35 μm.

16. The cosmetic product according to claim 1 , wherein the second polymer layer (P2) has a layer thickness of from about 30 μm to about 110 μm.
