Patent Application
20180133135
This application claims priority to German Patent Application No. 10 2016 222 636.3, filed Nov. 17, 2016, which is incorporated herein by reference in its entirety.
The present disclosure relates to the cosmetics sector, more particularly hair cleansing conditioners containing a polyether-modified polysiloxane, an amino/functional silicone, a hydrophobically-modified starch compound, as well as an amphoteric tenside. The present disclosure further relates to the use of the aforementioned active agent combination for achieving an optimal balance between a high conditioning effect and a clean hair feeling, as well as for improving the skin tolerance of cosmetic cleansing compositions.
Conventional hair cleansers usually comprise anionic tensides, i.e., surfactants. These are desirable and essential to removing sebum and other contaminants from the hair surface and the scalp. However, they also remove lipids and proteins from the hair and/or scalp during the cleansing process, thereby necessitating subsequent treatment with care products in order to regenerate the hair. In addition to daily cleansing, the structure of the hair can also be damaged by environmental influences (such as intense solar irradiation), mechanical stresses (such as intense combing under the heat of a hair dryer), physical or chemical treatments (such as coloring, curling or straightening the hair). This often results in split ends, hair breakage and/or loss of hair gloss. Hair damaged in this way is difficult to disentangle and style. Hence the need for a particularly mild hair cleanser, which removes the smallest amount of grease or no grease at all from the hair during the cleansing process and nourishes it at the same time.
Patent Application U.S. Pat. No. 6,723,309 proposes a new kind of nourishing hair cleanser—referred to as a hair cleansing conditioner. This is based on a complex mixture of conditioning agents, coolants, emulsifiers, moisturizers, pH stabilizers, preservatives, thickening agents, plant extracts and vitamins. The hair cleansing conditioner cleanses the hair, lends it more shine and body and makes it easier to style. The disadvantage of the hair cleansing conditioner, however, is its weak foaming power and its sometimes poor ability to be distributed and/or rinsed off the hair. Moreover, treatment with silicone-based cleansers—particularly when regularly applied to thin hair—can have an undesirable build-up effect.
The present disclosure therefore addresses the problem of providing hair cleansing conditioners that do not have the aforementioned disadvantages. More particularly, of providing hair cleansing conditioners with effective foaming power, which ideally contain no anionic (sulphate) tensides, yet nonetheless guarantee thorough and particularly mild cleansing. A further aim was to find suitable silicone-based active agents for the hair cleansing conditioner, which do not have any build-up effect, even after regular application to the hair.
A hair cleansing conditioner is provided in an exemplary embodiment. The hair cleansing conditioner includes from about 0.01 to about 10 wt. % of at least one polyether-modified polysiloxane, relative to the weight of the entire composition. The hair cleansing conditioner includes from about 0.01 to about 10 wt. % of at least one amino-functional silicone, relative to the weight of the entire composition. The hair cleansing conditioner also includes from about 0.01 to about 15 wt. % of at least one hydrophobically-modified starch compound, relative to the weight of the entire composition. Further, the hair cleansing conditioner includes from about 0.10 to about 30 wt. % of at least one amphoteric tenside, relative to the weight of the entire composition.
In another embodiment, a cosmetic use of an active ingredient combination is provided in hair cleansing conditioners for achieving an optimal balance between a high conditioning effect and a feeling of clean hair or for improving the skin tolerance of cosmetic hair cleansing compositions. The exemplary active ingredient combination includes from about 0.01 to about 10 wt. % of at least one polyether-modified polysiloxane, from about 0.01 to about 10 wt. % of at least one amino-functional silicone, from about 0.01 to about 15 wt. % of at least one hydrophobically-modified starch compound, and from about 0.10 to about 30 wt. % of at least one amphoteric tenside.
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.
Surprisingly, it has now emerged that the aforementioned problems are ideally solved by hair cleansing conditioners which, in addition to two special silicone compounds, contain at least one hydrophobically-modified starch compound and an amphoteric tenside.
Such hair cleansing conditioners form mild cleansing products with very good foaming and conditioning properties, which lend the hair gloss and resilience even with repeated application, without the build-up effect. The hair cleansing conditioners achieve an optimal balance between a high conditioning effect and a clean hair feeling, and are well tolerated by the skin.

Such waxes are available from Kahl & Co., Trittau, for example. Other solids include
Exemplary oil, wax and/or fatty components (fii) according to this present disclosure are selected from fatty alcohols and/or plant oils due to properties thereof, which nourish and which have no negative effect on the stability of the compositions as contemplated herein. Examples of suitable constituents (fii) are cetyl alcohol, stearyl alcohol, cetearyl alcohol and/or one or more of the aforementioned plant oils.
The proportions by weight of the oil, wax and/or fatty components (fii) of the total weight of the hair cleansing conditioners according to exemplary embodiments herein are from about 0.01 to about 10.00 wt. %, such as from about 0.25 to about 9.00 wt. %, for example from about 0.50 to about 8.00 wt. %, such as from about 0.75 to about 7.50 wt. %.
In a further exemplary embodiment, the hair cleansing conditioners as contemplated herein contain—relative to their weight—from about 0.01 to about 10.00 wt. %, such as from about 0.25 to about 9.00 wt. %, for example from about 0.50 to about 8.00 wt. % such as from about 0.75 to about 7.50 wt. % of at least one saturated or unsaturated, linear or branched C12-C24 alcohol, such as selected from the compounds known under the INCI trade names cetyl alcohol, stearyl alcohol and/or cetearyl alcohol.

The proportion by weight of the vitamins(s), vitamin derivatives(e), and/or the vitamin precursor(s) (ei) of the total weight of the hair cleansing conditioners according to certain embodiments is from about 0.005 to about 1.00 wt. %, such as from about 0.01 to about 0.50 wt.-%.
In a further exemplary embodiment, the hair cleansing conditioners as contemplated herein contain—relative to their weight—additionally from about 0.001 to about 2.00 wt. %, such as from about 0.005 to about 1.00 wt. %, for example from about 0.01 to about 0.50 wt. % of at least one vitamin, one vitamin derivative and/or a vitamin precursor, for example selected from nicotinic acid amide and/or panthenol.
The hair cleansing conditioners according to exemplary embodiments here are conventional rinse-off products, such as a nourishing shampoo and/or a foaming, rinse-off nourishing conditioner. In other embodiments, the hair cleansing conditioners as contemplated herein are applied as cleansing hair foams. This guarantees a particularly good distribution and dosability of the hair cleansing conditioners.
The hair cleansing conditioners as contemplated herein therefore exist in certain embodiments as cleansing nourishing foam.
For this purpose, the hair cleansing conditioners as contemplated herein are packaged in a dispensing device, which constitutes either a compressed gas container (aerosol container) additionally filled with a propellant, or a non-aerosol container. The compressed gas container, by employing which a product is distributed through a valve by the gas pressure inside the container, is defined as an “aerosol container”. Conversely, a container under normal pressure, by employing which a product is distributed by a pumping or squeezing system via a mechanical effect, is defined as a “non-aerosol container”. Within this embodiment, the hair cleansing conditioners typically exist as an aerosol foam. Exemplary hair cleansing conditioners therefore also contain at least one propellant. The hair cleansing conditioners as contemplated herein, which exist in the form of an aerosol product, can be manufactured in a usual manner. As a rule, all constituents of the hair cleansing conditioners as contemplated herein, with the exception of the propellant, are placed in a suitable pressure-resistant container. This is then closed by employing a valve. The desired quantity of propellant is then added by employing conventional technology. In the embodiment as an aerosol foam, suitable propellants as contemplated herein are selected from N2O, dimethylether, CO2, air, alkanes with 3 to 5 carbon atoms, such as propane, n-butane, iso-butane, n-pentane and iso-pentane, and the mixtures thereof. According to the embodiment of an aerosol foam, the stated alkanes, mixtures of said alkanes or mixtures of said alkanes with dimethyl ether are used as the only propellant. However, the present disclosure also explicitly comprises the co-utilization of propellants of the type of fluorochloro hydrocarbons, more particularly however, the fluoro hydrocarbons. Dimethylether, propane, n-butane, iso-butane and the mixtures thereof are used in certain embodiments. Mixtures of propane and butane are used in certain embodiments as the only propellant in the propane to butane weight ratio from about 70 to about 30 to about 15 to about 85. These mixtures may be used in the hair cleansing conditioners as contemplated herein in a quantity of from about 1.00 to about 50.0 wt. %—relative to the weight of the total hair cleansing conditioners, such as quantities of from about 2.00 to about 40.0 wt. %, for example from about 3.00 to about 30.0 wt. %, such as from about 4.00 to about 20.0 wt. %. As contemplated herein, butane means n-butane, iso-butane and mixtures of n-butane and iso-butane.
In a further embodiment, the hair cleansing conditioners as contemplated herein exist as aerosol foam in an aerosol container and also contain at least one propellant. Within such an embodiment, it may be advantageous for the hair cleansing conditioners to contain the propellant—such as a mixture from propane/butane—in a percentage by weight of from about 1.00 to about 50.0 wt. %, such as from about 2.00 to about 40.0 wt. %, for example from about 3.00 to about 30.0 wt. %, such as from about 4.00 to about 20.0 wt. % of the total weight of the composition.
Other active ingredients, adjuvants and additives, which may be contained in the hair cleansing conditioners according to certain embodiments, include:
A second subject matter of the present disclosure is the cosmetic use of the hair cleansing conditions as contemplated herein for the mild cleansing and highly-effective care of hair and scalp, more particularly of brittle, damaged, dull and/or lank hair.
A third subject matter of the present disclosure is the cosmetic use of an active ingredient combination, containing
A fourth subject matter of the present disclosure is the cosmetic use of an active ingredient combination, containing
A fifth subject matter of the present disclosure is a cosmetic method for the treatment of hair, wherein the hair cleansing conditioner as contemplated herein is applied to wet hair, massaged in and rinsed off after an exposure time.
The hair cleansing conditioners as contemplated herein apply, mutatis mutandis, to certain embodiments of the use as contemplated herein and of the method as contemplated herein.
The following examples are intended to explain the subject matter of the present disclosure without, however, having any limiting effect.
The following hair cleansing conditioners as contemplated herein were produced, all numerical values in the examples below—unless otherwise specified—corresponding to the quantity of the respective active ingredient in percentage by weight, relative to the total weight of the agent:
100% healthy women (no allergies or skin problems) between about 18 and about 50 years old (50% from about 18-about 34 years; 50% from about 35-about 50 years) who had tested, in a blind test, the hair cleansing conditioners as contemplated herein against competitor and/or comparison products (in anonymized and coded form) between 29 Oct. and 26 Nov. 2015 where surveyed. Half of the women had used the product as contemplated herein from about 3-about 4 times per week and the other half had used the comparison product.
The skin tolerance of the hair cleansing conditioner as contemplated herein as per Formula 46 was evaluated against a conventional nourishing shampoo (comprising as tenside SLES and cocoamphoacetate and instead hydroxypropyl starch phosphate and silicones a), b) as nourishing agents Polyquaternium-10 and Dimethicone) by employing a dermatological patch test. The results of the patch test can be seen in Tables 1 and 2 below:
The values from Tables 1 and 2 show that the hair cleansing conditioners as contemplated herein have a better skin tolerance than a conventional nourishing shampoo based on anionic sulphate tensides.
While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the various embodiments in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment as contemplated herein. It being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the various embodiments as set forth in the appended claims.
