The present invention generally relates to hair treatment agents including Polyquaternium-71 and cationic silicones.
The need exists to improve hair-care products further and to provide them with further advantageous properties. In particular, a care complex should be provided which ideally can also be used in combination with oxidizing agents and surfactant agents.
Environmental influences and oxidative hair treatments often lead to impaired combability of dry and wet hair. Furthermore, the gloss and moisture balance are disadvantageously affected by the attack on the external structure of the keratinic fibers. A further consequence of repeated treatments of keratinic fibers with surfactant and/or oxidative agents is marked regreasing of the keratinic fibers and a marked tendency towards increased formation of dandruff.
It is therefore desirable to reduce the side effects of environmental influences and of oxidative and surfactant hair treatments, preferably during the oxidative or surfactant hair treatment itself but also after the oxidative or surfactant hair treatment, without impairing the effectiveness of the oxidative or surfactant cosmetic, in particular with regard to color intensity, color-fastness, lightening performance or waving performance, and to prevent regreasing of the keratinic fibers and the increased formation of dandruff. In addition, the oxidative treatment of keratinous fibers, in particular human hair, should also be combined with the application of an effective protection of fibers from environmental influences, e.g. UV protection, in one application step in the form of a 2-in-1 product.
Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with the accompanying drawings and this background of the invention.
A hair treatment agent including in a suitable cosmetic carrier, based in each case on the overall composition of the agent, at least 0.01 to 10.0 wt. % Polyquaternium-71, and at least one cationic amino silicone having at least three terminal amino functional groups in a total quantity of 0.01 to 5.0 wt. %.
The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention.
Surprisingly, it has now been found that the object of the invention is achieved to an excellent extent by a hair treatment agent, which includes an active substance complex including as essential ingredients at least Polyquaternium-71 and at least one cationic silicone with at least three terminal amino functional groups.
Hair treatment agents including this active substance complex lead to an improvement in brightness, gloss and moisture balance and to protection from oxidative damage and prevention of regreasing of keratinic fibers as well as to an increase in the wash resistance of dyed keratinic fibers, in particular human hair, and to a time delay in the formation of dandruff.
Hair treatment agents within the meaning of the present invention are, for example, hair shampoos, hair conditioners, conditioning shampoos, hair rinses, deep conditioners, hair masques, hair tonics, hair coloring shampoos or combinations thereof. In particular, the hair treatment agents according to the invention are understood to be hair-conditioning compositions, such as hair rinses, deep conditioners, hair masques, hair oils and lotions that are either leave-on products, i.e. remaining on the hair until the next hair wash, or rinse-off products, i.e. to be rinsed off again a few seconds to a few hours after application.
Combability is understood according to the invention to be both the combability of the wet fibers and the combability of the dry fibers.
Handle is defined as the tactility of a fiber collective, with the person skilled in the art feeling and evaluating the parameters of fullness and suppleness of the collective by sensory means.
Shaping is understood to be the ability to impart a change of shape to a collective of previously treated keratin-including fibers, in particular human hair. In hair cosmetics, the term “styling” is also used.
Restructuring within the meaning of the invention is understood to be a reduction of damage to keratinic fibers from a wide variety of influences. For example, restoring the natural strength plays an essential part here. Restructured fibers are distinguished by improved gloss, improved handle and greater ease of combing. In addition, they exhibit improved strength and elasticity. Moreover, successful restructuring can be detected physically as an increase in melting point compared with the damaged fiber. The higher the melting point of the hair, the stronger the structure of the fiber.
Washfastness within the meaning of the invention is the retention of the original dyeing with respect to shade and/or intensity when the keratinic fiber is exposed to the repeated influence of aqueous agents, in particular surfactant-including agents such as shampoos.
Furthermore, the compositions according to the invention including the active substance complex according to the invention are distinguished by a significantly improved state of the keratinic fibers in relation to the moisture balance of the keratinic fibers. Furthermore, the active substance complex according to the invention leads to a distinct protection of the keratinic fibers from the effects of heat, e.g. during blow-drying of keratinic fibers. The protection of the surface of keratinic fibers from the effect of heat is of great importance, particularly during the use of straighteners or hair dryers. Finally, it has surprisingly been found that the compositions according to the invention lead to a significantly delayed resoiling of the keratinic fibers. Moreover, the formation of dandruff on the scalp is significantly delayed.
An aqueous cosmetic carrier includes at least 50 wt. % water.
Aqueous-alcoholic cosmetic carriers within the meaning of the present invention are understood to be aqueous solutions including 3 to 70 wt. % of a C1-C6 alcohol, in particular methanol, ethanol or propanol, isopropanol, butanol, isobutanol, tert.-butanol, n-pentanol, isopentanols, n-hexanol, isohexanols, glycol, glycerol, 1,2-pentanediol, 1,5-pentanediol, 1,2-hexanediol or 1,6-hexanediol. The agents according to the invention can additionally include further organic solvents, such as e.g. methoxybutanol, benzyl alcohol, ethyl diglycol or 1,2-propylene glycol. All water-soluble organic solvents are preferred here. Water is particularly preferred.
The present invention therefore firstly provides a hair treatment agent including in a suitable cosmetic carrier—based in each case on the overall composition of the agent—
When this combination is used, surprisingly good properties of the treated hair, in particular improved combability, improved gloss and improved elasticity, are obtained together with significantly increased wash resistance of dyed hair as well as longer durability at the same time as better reshaping performance in waving procedures, such as the water wave and permanent wave.
The first essential component is Polyquaternium-71.

Moench, all types of vine and pericarp of Litchi chinensis are preferred.
The plant extracts can be used according to the invention both in pure form and in dilute form. Where they are used in dilute form, they usually include approx. 2-80 wt. % active substance and, as solvent, the extracting agent or mixture of extracting agents used to obtain them.
It may occasionally be necessary to use anionic polymers. Examples of anionic monomers from which these polymers can consist are acrylic acid, methacrylic acid, crotonic acid, maleic anhydride and 2-acrylamido-2-methylpropanesulfonic acid. The acid groups here can be completely or partially present as a sodium, potassium, ammonium, mono- or triethanolammonium salt. Preferred monomers are 2-acrylamido-2-methylpropanesulfonic acid and acrylic acid.
Anionic polymers including 2-acrylamido-2-methylpropanesulfonic acid as sole monomer or comonomer, wherein the sulfonic acid group can be completely or partially present as a sodium, potassium, ammonium, mono- or triethanolammonium salt, have proved most particularly effective.
Particularly preferred is the homopolymer of 2-acrylamido-2-methylpropanesulfonic acid, which is commercially available e.g. with the name Rheothik®11-80.
Preferred non-ionogenic monomers are acrylamide, methacrylamide, acrylic acid ester, methacrylic acid ester, vinylpyrrolidone, vinyl ether and vinyl ester.
Preferred anionic copolymers are acrylic acid-acrylamide copolymers and in particular polyacrylamide copolymers with monomers that include sulfonic acid groups. A polymer of this type is included in the commercial product Sepiger®305 from SEPPIC.
Likewise preferred anionic homopolymers are uncrosslinked and crosslinked polyacrylic acids. Preferred crosslinking agents in this case can be allyl ethers of pentaerythritol, of sucrose and of propylene. Compounds of this type are commercially available e.g. with the trademark Carbopol®.
Copolymers of maleic anhydride and methyl vinyl ether, in particular those with crosslinkages, are also color-retaining polymers. A maleic acid-methyl vinyl ether copolymer crosslinked with 1,9-decadiene is commercially available with the name Stabileze® QM.
The anionic polymers are included in the agents according to the invention preferably in quantities of 0.05 to 10 wt. %, based on the overall agent. Quantities of 0.1 to 5 wt. % are particularly preferred.
In a further embodiment, the agents according to the invention can include non-ionogenic polymers.
Suitable non-ionogenic polymers are e.g.:
The nonionic polymers are included in the compositions according to the invention preferably in quantities of 0.05 to 10 wt. %, based on the overall agent. Quantities of 0.1 to 5 wt. % are particularly preferred.
In another embodiment, the agents according to the invention should additionally include at least one UV light protective filter. UVB filters can be oil-soluble or water-soluble.
As oil-soluble substances, e.g. the following should be mentioned:
The following are suitable as water-soluble substances:
As typical UV-A filters, derivatives of benzoyl methane are particularly suitable, such as e.g. 1-(4′-tert.butylphenyl)-3-(4′-methoxyphenyl)propane-1,3-dione or 1-phenyl-3-(4′-isopropylphenyl)propane-1,3-dione. The UV-A and UV-B filters can, of course, also be used in mixtures. In addition to the aforementioned soluble substances, insoluble pigments are also suitable for this purpose, in particular finely dispersed metal oxides or salts, such as e.g. titanium dioxide, zinc oxide, iron oxide, aluminum oxide, cerium oxide, zirconium oxide, silicates (talc), barium sulfate and zinc stearate. The particles in this case should have an average diameter of less than 100 nm, preferably between 5 and 50 nm and in particular between 15 and 30 nm. They can have a spherical shape, but those particles that possess an ellipsoid shape or a shape deviating from the spherical form in another way can also be used.
Furthermore, the cosmetic agents can include additional active substance, auxiliary substances and additives, such as e.g.
With regard to further optional components and the amounts of these components used, explicit reference is made to the relevant handbooks known to the person skilled in the art.
The invention therefore also provides a method for hair treatment, in which a hair treatment agent according to claim 1 is applied onto the hair and rinsed off the hair after a period of exposure.
The period of exposure is preferably a few seconds to 100 minutes, particularly preferably 1 to 50 minutes and most particularly preferably 1 to 30 minutes.
A method in which a cosmetic agent according to claim 1 is applied onto the hair and remains there is also according to the invention. “Remains on the hair” is understood according to the invention to mean that the agent is not rinsed out of the hair immediately after its application. Instead, in this case the agent remains on the hair for more than 100 minutes up to the next hair wash.
Finally, the use of a composition as described above to reduce and/or delay flaking of the scalp is according to the invention.
The following examples are intended to explain the subject-matter of the present invention but without limiting it.
Unless otherwise specified, all quantitative data are parts by weight. The following formulations were prepared using known methods of production.
Care spray, also suitable for application as a foam and/or deep conditioner:
For application as a foam, the relevant formulation is either packaged in an aerosol container with a propellant or delivered as a foam from a pump bottle with an appropriate pump attachment, such as e.g. an Airfoamer.
For use as a deep conditioner or cream, fatty alcohol such as cetyl stearyl alcohol and/or ethylene glycol distearate and/or glycerol monostearate is added to the above formulations in quantities of 0.2 to 5.0 wt. %.
