This application claims priority to German Patent Application No. 10 2017 217 466.8, filed Sep. 29, 2017, which is incorporated herein by reference in its entirety.
The present disclosure relates to a cosmetic composition based on two specific copolymers for firming hair or for the temporary reshaping of keratin fibers, in particular human hair, and a method and use of this composition, and use thereof to improve the long-term hold and resistance to moisture.
The temporary shaping of hairstyles for a relatively long period of time up to several days generally requires the application of firming active ingredients. Hair treatment agents that serve to temporarily shape the hair thus play an important role. Appropriate agents for temporary shaping usually contain synthetic polymers and/or wax as firming active ingredient. Agents for assisting the temporary shaping of keratin-containing fibers can be provided for example in the form of hairspray, hair wax, hair gel or hair mousse.
The most important property of an agent for temporarily shaping hair, also referred to hereinafter as styling agents, lies in providing the treated fibers with the greatest possible hold in the newly modelled form—i.e. a form impressed on the hair. Reference is also made to a strong hairstyle hold or to a high holding power of the styling agent. The hold of a hairstyle is determined fundamentally by the type and quantity of the used firming active ingredient, however the further constituents of the styling agent can also have an effect.
In addition to a high holding power, styling agents must also satisfy a wide range of further requirements. These can be divided roughly into properties on the hair, properties of the particular formulation, for example properties of the mousse, of the gel, or of the sprayed aerosol, and properties that concern the handling of the styling agent, wherein the properties on the hair are attributed particular importance. In particular, moisture resistance, low stickiness (tack), and a balanced conditioning effect can be cited. Furthermore, a styling agent should be universally usable for all hair types where possible and should be mild on the hair and skin.
In order to satisfy the different requirements, a multiplicity of synthetic polymers which are used in styling agents have already been developed as firming active ingredients. These polymers can be divided into cationic, anionic, non-ionic and amphoteric firming polymers.
European patent application EP 3 069 709 A1 describes cosmetic polymer blends for the hair which, besides an oxyalkylene polymer, also contain the hydrophobically modified (meth)acrylic acid copolymer with the commercial name Luvigel Fit (INCI: Acrylates (C10-30) Alkyl Methacrylate Copolymer).
When applied to the hair, the polymers ideally form a polymer film on the hair that on the one hand provides the hairstyle with a strong hold, but on the other hand is sufficiently flexible so as not to break when stressed. If the polymer film is too brittle, what are known as film flakes form, that is to say residues that detach as the hair moves and give the impression that the user of the corresponding styling agent has dandruff. Similar problems are encountered when wax is used as firming active ingredient in the styling agent. If the styling agent is a gel or a paste, the polymers should additionally have thickening properties.
Cosmetic compositions for temporarily reshaping keratin fibers and methods for using such cosmetic compositions are provided herein. In an exemplary embodiment, a cosmetic composition for temporarily reshaping keratin fibers comprises a) at least one non-cross-linked, hydrophobically modified (meth)acrylic acid copolymer, and b) at least one copolymer. The at least one copolymer b) is formed from at least one monomer (b1) selected from acrylic acid, methacrylic acid, acrylic acid alkyl esters and methacrylic acid alkyl esters, and at least one amphoteric monomer (b2) of formula (I)
wherein R1 stands for H or CH3, R2 and R3 independently of one another stand for optionally branched C1-10 alkyl and n stands for an integer from 1 to 20.
The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the subject matter as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
One object of the present disclosure was to provide a further suitable polymer combination which is exemplified by good film-forming and/or firming properties, a very high degree of hold without having to compromise on flexibility and good moisture resistance—in particular resistance to perspiration and water—and which additionally is suitable for the production of stable viscous and stable transparent cosmetic compositions. In particular, currently available styling agents can be improved even further in that a good combination of stiffness and long-term hold (high humidity curl retention) is not always ensured sufficiently. One object of the present disclosure is therefore to provide styling agents that, besides the above-mentioned properties, in particular also produce good stiffness and a good long-term hold.
This has been achieved in accordance with the present disclosure by a combination of two specific anionic copolymers.
The following is provided by employing the present disclosure:
A cosmetic composition for the temporary shaping of keratin fibers:
The cosmetic composition according to point 1, wherein the proportion by weight of the copolymer a) in the total weight of the composition is from about 0.1 to about 15% by weight, preferably from about 0.2 to about 10% by weight, and in particular from about 0.5 to about 7.0% by weight.
The cosmetic composition according to either one of the preceding points, wherein the copolymer a) is obtained by reacting
The cosmetic composition according to any one of the preceding points, wherein the copolymer a) is obtained by reacting
The cosmetic composition according to any one of the preceding points, wherein the copolymer a) is selected from the group of compounds with the INCI name Acrylates/C10-30 Alkyl Methacrylate Copolymer.
The cosmetic composition according to any one of the preceding points, wherein the proportion by weight of the copolymer b) in the total weight of the composition is from about 0.1 to about 10% by weight, preferably from about 0.2 to about 7.0% by weight, and in particular from about 0.5 to about 5.0% by weight.
The cosmetic composition according to any one of the preceding points, wherein the copolymer b) comprises at least two monomers (b1) different from one another.
The cosmetic composition according to any one of the preceding points, wherein the monomer (b2) of copolymer b) is selected from (meth)acryloyl alkyl betaine of formula (I), wherein R1, R2 and R3 each stand for CH3 and n stands for 2.
The cosmetic composition according to any one of the preceding points, wherein the copolymer b) is selected from the group of compounds with the INCI name Methacryloyl Ethyl Betaine/Acrylates Copolymer.
The cosmetic composition according to any one of the preceding points, wherein the ratio by weight of copolymer a) to copolymer b) is from about 10:1 to about 1:10, preferably from about 5:1 to about 1:5 and in particular from about 3:1 to about 1:3.
The cosmetic composition according to any one of the preceding points, it also contains
The cosmetic composition according to the foregoing point, wherein the proportion by weight of the polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer c) in the total weight of the cosmetic composition is from about 0.1 to about 10% by weight, preferably from about 2.0 to about 8.5% by weight, and in particular from about 3.0 to about 7.0% by weight.
The cosmetic composition according to any one of the preceding points, wherein the composition, based on its total weight, contains from about 0.05 to about 2.0% by weight, preferably from about 0.1 to about 1.0% by weight, and in particular from about 0.1 to about 0.5% by weight of an amino alcohol, preferably 2-amino-2-methylpropanol.

Use of a cosmetic composition according to any one of the preceding points for the temporary shaping of keratin-containing fibers, in particular human hair.
Use of a cosmetic composition according to any one of the preceding points for improving the hold of temporarily shaped keratin fibers.

A method for the temporary shaping of keratin-containing fibers, in particular human hair, in which the keratin fibers are exposed to a cosmetic composition according to any one of the preceding points and are fixed temporarily in their form.
It has surprisingly been found within the scope of the present disclosure that an improved hold of styling products can be achieved by combining two constituents known per se which are already used in styling products. Other properties usually required of styling products, such as resistance to moisture, stiffness and low tack, are retained. A good combination of properties of this kind was not anticipated, not even in the knowledge of the individual components, and was surprising. It has been found by way of experimentation that an effect going significantly beyond a mere additive effect of said constituents, i.e. a synergistic effect, is obtained in respect of the hold and was demonstrated in the HHRC test (high humidity curl retention test).
The term “keratin fibers” in accordance with the present disclosure comprises fur, wool and feathers, but in particular human hair.
The key constituents of the cosmetic composition are the non-cross-linked, hydrophobically modified copolymer a) and the copolymer b) different from the copolymer a).
Besides the above-mentioned advantages, the cosmetic compositions are exemplified by an improved long-term hold. A ratio by weight of the polymers a) and b) in the cosmetic composition of from about 10:1 to about 1:10, preferably from about 5:1 to about 1:5, and in particular from about 3:1 to about 1:3 has proven to be particularly advantageous for the cosmetic properties of the agents as contemplated herein, for example the resistance to moisture and low tack.

Cosmetic compositions that are very particularly preferred comprise, in relation to their total weight, a water and ethanol content between from about 50 and about 95% by weight, preferably between from about 60 and about 90% by weight, and in particular between from about 65 and about 85% by weight.
As alcohols, the lower alcohols with from about 1 to about 4 carbon atoms usually used in particular for cosmetic purposes, such as isopropanol, can be contained.
Examples of water-soluble solvents as cosolvents are glycerol and/or ethylene glycol and/or 1,2-propylene glycol in an amount of from about 0 to about 30% by weight in relation to the total product.
The composition of some preferred cosmetic agents can be deduced from the following tables (specified amounts in % by weight are in relation to the total weight of the cosmetic agent unless specified otherwise).
The entry “Misc” is to be understood in accordance with the present disclosure to mean a cosmetic carrier, in particular water (unless listed separately) and optionally further usual constituents of styling products.
The cosmetic composition of the present disclosure can be provided in the forms that are usual for the temporary reshaping of hair, for example as a hair gel, hairspray, hair mousse, or hair wax. The cosmetic composition is preferably provided as a hair gel.
Both hair mousses and hairsprays require the presence of propellants. In accordance with the present disclosure, however, no hydrocarbons or only small quantities of hydrocarbons should preferably be used for this. Propane, propane/butane mixtures and dimethyl ethers are particularly suitable propellants in accordance with the present disclosure.
The present disclosure also relates to the use of cosmetic compositions as contemplated herein for temporarily reshaping keratin fibers, in particular human hair, and to a method for the temporary shaping of keratin fibers, in particular human hair, in which the cosmetic composition as contemplated herein is applied to keratin fibers and the form of said fibers is temporarily fixed.
A further subject of this patent application is the use of a cosmetic composition as contemplated herein to improve the hold of temporarily shaped keratin fibers.
A last subject matter of this patent application is the use of a cosmetic composition as contemplated herein to improve the moisture resistance of temporarily shaped keratin fibers.
The following hair gel was prepared:
130% by weight active substance in water
250% by weight active substance in water
The amounts specified in the table are given in % by weight of the respective raw materials, in relation to the total composition. The polymer content in each of the compositions V1, V2 and E1 was 1.0% by weight.
The moisture resistance of cleaned strands of Kerling hair was determined for the obtained styling agents by employing an HHCR test (high humidity curl retention test: 6 h; mean value from 5 hair strands in each case):
The polymer combination E1 as contemplated herein therefore demonstrated a synergistic effect, going considerably beyond a purely additive effect, in respect of the moisture resistance.
