Description

A PRODUCT RELEASE SYSTEM FOR ATOMIZING COSMETIC HAIR COMPOSITIONS CONTAINING CATIONIC POLYMERS

The object of the present invention is a product release system for atomizing cosmetic compositions, which has pressure-resistant packaging, a capillary-containing spray head, and a propellant-containmg cosmetic composition, and wherein the composition contains at least one film-forming, hair-setting, or hair-conditioning cationic polymer. The object of the invention is thus a corresponding method for hair treatment.

Many cosmetic hair products contain cationic polymers as hair-setting or hair- conditioning ingredients. In the form of foams, cationic polymers provide the hair with good combing properties after application in wet hair and effect good setting with a good hold in dry hair. In shampoos, permanent wave solutions, fixing products, and hair colors, cationic polymers are used to provide good combing properties in wet hair and good hold properties in dry hair. They provide hairstyle stability and increase hair volume in dry hair. However, cationic polymers have not been widely used up to now in higher- viscosity products such as gels, waxes, hairdressing creams, or treatments, because the composition as well as the product consistency and the resulting more difficult application meant that the advantages of the cationic polymers couldn't be fully realized on the hair.

A process for atomizing liquid is known from WO 03/051523 Al with which the spray is formed using a capillary. Only the application with respect to atomizing liquid compositions is described. A fixture for atomizing liquid products is described in WO 03/051522 A2, wherein the spray is formed using a capillary. Only the use of liquid compositions for atomizing, which can also be highly viscous, is described, wherein, however, 0.00073 lb/in² s (5,000 mPa s) is mentioned as the maximum sprayable viscosity.

There is a need for products that will realize the advantageous hair-setting and hair-conditioning properties of cationic polymers even in application forms such as hair waxes, styling gels, hairdressing creams, or creamy treatments and that will combine the advantageous properties with these forms of application. The object of the invention, in particular, was to further improve the distributability on hair, the volume effect, the setting effect and/or hairstyle stability, the combing properties, the hair shine, and/or the holding properties of conventional hair treatment compositions, which were previously unavailable as a spray, and/or the hair treated with said composition.

The object of the invention is a product release system for atomizing cosmetic compositions. The product release system has the following features:

(a) pressure-resistant packaging,

(b) a spray head containing a capillary, and (c) a propellant-containing cosmetic composition, wherein atomization is done using the capillary and the composition contains at least one film-forming, hair-setting, or hair-conditioning cationic polymer.

The term "atomize" is understood to mean the release of the product in the form of dissipated particles. The dissipated particles can have varying shapes, consistencies, and sizes. The properties of the atomized particles can include everything from fine aerosol atomized spray to liquid drops, snow-like drops, solid spray flakes and spray foam.

The quantities of ingredients (e.g. wt. %) indicated in the following are each based on the basic composition without propellant unless explicitly indicated otherwise. The quantities of the propellant are based on the total composition including propellant.

The composition is preferably non-liquid at 77°F (25 °C) and/or has a viscosity greater than 0.00073 lb/in² s (5,000 mPa s) (measured with a HAAKE VT-550 Rheometer, SV-DIN test body at a temperature of 77°F (25°C) and a shear speed of 12.9 s^"1).

The properties of the compositions to be used according to the invention that are related to consistency are based on the base composition without propellant (unless explicitly indicated otherwise). Non-liquid compositions in terms of the invention are particularly non-flow-capable compositions, which, for example, can be determined due to the fact that they will not flow off of a glass surface tilted at 45° at a temperature of 77⁰F (25°C). Gel compositions are characterized in that the memory module G' is larger than the loss module G" at 77⁰F (25°C) with oscillographic measurements in the typical measurement range (0.01 to 40 Hz).

The viscosity of the composition to be used is preferably greater than 0.00073 (5,000) up to 0.0145 (100,000), and especially preferably 0.00145 (10,000) to 0.00725 lb/in² s (50,000 mPa s), or very especially preferably 0.00362 (25,000) to 0.0051 lb/in² s (35,000 mPa s), measured with a HAAKE VT-550 Rheometer, SV-DIN test body at a temperature of 77°F (25⁰C) and a shear speed of 12.9 s^"1.

Aerosol spray cans constructed of metal or plastic can be used as the pressure- resistant packaging. Preferred metals are tin plates and aluminum, while the preferred plastic is polyethylene terephthalate.

Suitable spray systems with capillary-containing spray heads, with which the spray is formed using a capillary, are described in WO 03/051523 Al and in WO 03/051522 A2. The capillaries preferably have a diameter of 0.00394 (0.1) to 0.03937 in (1 mm), or particularly 0.00787 (0.2) to 0.02362 in (0.6 mm), and a length that is preferably 0.1968 (5) to 3.937 in (100 mm), or particularly 0.1968 (5) to 1.9685 in (50 mm). The spray principle is also described in Aerosol Europe, vol. 13, no. 1-2005, pages 6-11. The spray system is based on the principle of capillary atomization. The conventional swirl nozzle as well as, if necessary, the uptake tube are replaced by capillaries. The energy-consuming and propellant-intensive swirling of the content of the can and the required strong dilution of the product with solvents is not necessary as compared to conventional spray systems. Even if only a small quantity of propellant is used, the product rises upward on the wall of the uptake tube capillary and is propelled, after the valve in the (wider) capillary of the spray head, in the direction of the exit opening, hi this manner, small drops from the flowing propellant are torn from the surface of the liquid and continue to flow as aerosol. Since there is no swirl chamber to inhibit the flow of the product nor any atomizing nozzle available, the energy in the system can be used much more efficiently to create the desired spray. The spray rate can be adjusted via the selection of the capillary geometry in conjunction with the interior pressure created by the propellant or a propellant mixture. Preferred spray rates are 0.00035 (0.01058) to 0.0176 oz/s (0.5 g/s), particularly 0.00353 (0.1) to 0.01 oz/s (0.3 g/s). The size of the spray drops created with the atomization can be adjusted via the selection of the capillary geometry in conjunction with the interior pressure or the viscosity of the composition. Suitable capillary atomization systems can be obtained in a product called TRUSPRAY® from Boehringer Ingelheim microParts GmbH.

The preferred drop size distributions are those with which the dv(50) value is a maximum of 0.00393 in (100 /mi), e.g. of from 0.00197 (50) to 0.00393 in (100 μm), with a maximum of 0.00354 in (90 μm) being especially preferred, e.g. of from 0.00275 (70) to 0.00354 in (90 μm), and/or with which the dv(90) value is a maximum of 0.0629 in (160 μm), e.g. of from 0.00354 (90) to 0.0629 in (160 μm), with a maximum of 0.0059 in (150 μm) being especially preferred, e.g. of from 0.00452 (115) to 0.0059 in (150 μm). The dv(50) or dv(90) values provide the maximum diameter that 50% or 90% of all droplets have. The drop size distribution can, for example, be determined with the help of a particle measurement unit based on laser beam diffraction, e.g. a Malvern particle sizer measuring device. Compositions that form a snow-like consistency, flakes, or foam (spray foam) upon exiting the capillary spray system are also preferred.

The propellant to be used can be selected from lower alkanes, particularly C3 to C5 hydrocarbons such as, for example, n-butane, i-butane, and propane, or also mixtures thereof, as well as dimethylethers or fluorine hydrocarbons such as F 152a (1,1-difluoroethane) or F 134 (tetrafluoroethane) as well as other gaseous propellants present with the pressures considered, such as, for example, N₂, N₂O, and CO₂ as well as mixtures of the aforementioned propellants. The propellant is preferably selected from propane, n-butane, isobutane, dimethylether, fluorinated hydrocarbons, and mixtures thereof. The content of propellant is, in addition, preferably 15 to 85 wt. %, with 25 to 75 wt. % being especially preferred.

The composition contains cosmetically acceptable solvents, preferably an aqueous, alcoholic, or aqueous alcoholic medium. The lower alcohols with 1 to 4 C atoms, such as ethanol and isopropanol, can be contained as alcohols, particularly those typically used for cosmetic purposes. The composition can be in a pH range of 2.0 to 9.5. A pH range of 4 to 8 is particular preferred, providing no special application forms require other pH values. As additional co-solvents, organic solvents or a mixture of solvents with a boiling point of less than 752°F (400°C) can be contained in a quantity of from 0.1 to 15 wt. % or preferably of from 1 to 10 wt. %. Unbranched or branched hydrocarbons such as n- pentane, hexane, isopentane, and cyclic hydrocarbons such as cyclopentane and cyclohexane are particularly suitable as additional co-solvents. These volatile hydrocarbons can also be used as propellants. Other, especially preferred water-soluble solvents are glycerol, ethylene glycol, and propylene glycol in a quantity of up to 30 wt. %.

The product release system according to the invention can be used for hair treatment.

The compositions can be agents for the care of hair such as, for example, hair-repair products or hair rinses, which, for example, can be applied as leave-on or rinse-off products; agents for the temporary reshaping and/or stabilizing of the hairstyle (styling agent), for example hair sprays, hair lacquers, hair gels, hair waxes, styling creams, etc.; permanent, semipermanent, or temporary hair colorants, for example oxidative hair colorants or nonoxidative hair tinting agents or hair bleaching agents; permanent hair restructuring agents, for example in the form of a mildly alkaline or acidic permanent wave or hair straightening agents containing a reducing agent, or in the form of permanent wave fixing agents containing an oxidizing agent.

Instead of being sprayed directly onto the hair, the product can also be placed in the hands or on an application device such as, for example, a comb or a brush, and then distributed into the hair, particularly if the product has a snow-like consistency, or it is in the form of flakes or foam.

The products according to the invention are characterized, constrained by their special application with the special aerosol spray system to be used according to the invention, by an excellent distribution capacity in conjunction with a good hairstyle stability with good hold as well as shine for the hair. An additional advantage of the products according to the present invention is that differing spray properties can be precisely adjusted by simply varying the propellant, the propellant composition, or the propellant pressure; these spray properties were not previously possible for the underlying active ingredient compositions. The spray properties include everything from a fine aerosol atomized spray and snow-like drops to flakes of spray and spray foam.
