Patent Application
20200188256
This application claims priority to German Patent Application No. 10 2018 221 974.5, filed Dec. 17, 2018, which is incorporated herein by reference in its entirety.
The present disclosure generally relates to hair care compositions, and more particularly relates to a silicone-free, transparent hair conditioning composition comprising bis-(isostearoyl/oleoyl isopropyl) dimonium methosulfate. The present disclosure also relates to the use of the compositions for the care of keratinous fibers.
Hair care compositions are used to style, cleanse and provide a pleasant feel to the hair. Such compositions come in a variety of forms, and include shampoos, conditioners, leave-on conditioning sprays and styling products.
Some hair care compositions, such as conditioners, are used to moisturize and condition the hair, to restore some of the moisture that was removed by a cleansing or shampoo composition. Such compositions may include conditioning agents, which act to retain moisture in the hair by a variety of mechanisms. Some conditioning agents, such as dimethicone, form a barrier and act to prevent the evaporation of moisture from the hair. Other agents, such as propylene glycol, act as humectants to attract moisture to the hair. In each case, the benefit persists only as long as the benefit agent is present on the hair. As such, providing an encapsulated benefit agent may provide increased benefits to hair feel and appearance by providing an extended release of the benefit agent by continuing to deposit the benefit agent onto the hair as the hair is touched, combed, brushed, or otherwise manipulated.
Additional hair care compositions are leave-in compositions. These include styling gels, hairsprays, creams, pomades, or waxes. Such compositions may also include benefit agents, such as moisturizing ingredients, conditioning ingredients, and illuminating ingredients. These benefit agents act immediately upon contact with the hair but may decrease in efficacy over time. As a result, providing an encapsulated benefit agent may assist the benefit agent to provide increased benefit to hair feel and appearance by providing a gradual deposit of the benefit agent onto the hair as the hair is physically manipulated and the capsules are opened, releasing the benefit agent onto the hair.
In addition to the natural environmental influences, human hair is exposed to a number of other, in particular cosmetic, stresses. To these, the strains include, for example, the coloring of the hair and its deformation, for example by a perm. To reduce the adverse effects of the hair structure affecting (environmental) influences, but also to maintain and improve the natural hair structure cosmetic hair products are used. An essential active ingredient in many of these cosmetics are the organosilicon compounds, in particular the silicones such as trisiloxanes, which are exemplified by nourishing properties. The disadvantages of these silicones are the reduced penetration of active ingredients and auxiliaries into the hair due to wetting of the hair surface and the hair styling being hampered by the wetting of the hair surface. Further, due to their persistence in the environment, it is preferable to dispense with the use of cyclomethicones.
The provision of low-silicone or silicone-free care products is therefore a relevant task in the field of hair cosmetics. However, silicone-free leave-on products do not always exhibit the same caring properties as silicone-based products, and it is a challenge to formulate cosmetically acceptable formulations at the care levels of silicones, without using silicones.
Accordingly, it is desirable to provide a hair conditioning composition that is silicone-free and that has enhanced care properties.
The inventors have surprisingly found that a transparent hair composition can be formulated, which is advantageously silicone-free. The composition comprises bis-(isostearoyl/oleoyl isopropyl) dimonium methosulfate and optionally an alcohol.
The silicone-free, transparent composition comprising bis-(isostearoyl/oleoyl isopropyl) dimonium methosulfate was particularly shown to achieve the beneficial care levels, especially compared to a commercially available leave-on silicone oil-based formulation.
Further details as to options for the components are disclosed herein.
Compositions according to the present specification are suitably provided in the form of a spray. The spray may also contain additional components, such as fragrances to provide the user with a sensory awareness that the benefit agent has been released.
There is also provided a method of conditioning keratin fibers, the method comprising contacting a keratin fiber with a conditioning-effective amount of a composition as disclosed herein.
There is also provided a method of conditioning keratin fibers, comprising contacting a plurality of keratin fibers with an amount of the composition as disclosed herein effective to increase the volume of the keratin fibers on styling.
There is also provided a method for conditioning keratin fibers, wherein the hair composition as disclosed herein is spray-applied onto wet or dry keratin fibers and left on the keratin fibers until they are next washed.
There is also provided a cosmetic preparation comprising the composition as disclosed herein in a transparent package suitable for dispensing the agent in the form of uniform, small droplets.
