Patent Application

The present disclosure present disclosure relates to cosmetic products comprising a mixture of at least two silicones.
There is a need to further improve hair care products and give them more beneficial properties. In particular, they should provide better care for the hair surface.
Environmental influences as well as oxidative, reductive and/or surfactant hair treatments often lead to hair damage. Such damage manifests itself, for example, in impaired combability of the dry and wet hair. Moreover, the gloss and moisture balance are adversely affected by the attacked outer structure of the hair. Conventional cosmetic care products therefore contain conditioning polymers, such as cationic polymers or silicone oils.
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.
It is therefore an object of the present disclosure present disclosure to reduce the side effects/damage of environmental influences and of oxidative, reductive and/or surfactant hair treatments and to condition the hair.
Surprisingly, it has now been found that the above-mentioned challenges are solved to an excellent degree by a cosmetic agent comprising two selected silicones.
Such a cosmetic agent provides intensive conditioning of keratinous fibers, especially human hair.
A first object of the present disclosure present disclosure is therefore a cosmetic agent for the treatment of keratinous fibers, comprising (relative to the weight of the entire agent)
a) 0.1 to 10% by weight of a hydroxy-terminated polyorganosiloxane,
b) 0.1 to 10% by weight of a reaction product of a hydroxy-terminated polyorganosiloxane with an acid and/or a fatty alcohol and/or a wax, and
c) an aqueous or aqueous-alcoholic carrier.
In principle, keratin fibers are understood to include all animal hair, for example wool, horsehair, angora hair, furs, feathers and products or textiles made from them. We are addressing here, however, human hair in particular.
In a preferred form of the present disclosure present disclosure, the cosmetic agents are used for the care/conditioning of keratinous fibers, in particular human hair. Therefore, conditioning agents such as hair conditioners or hair treatments are preferred cosmetic agents.
An oxidative hair treatment is defined as the action on keratinous fibers of an oxidative cosmetic agent comprising, in a cosmetic carrier, at least one oxidizing agent.
A reductive hair treatment is defined as the action on keratinous fibers of a reductive cosmetic agent comprising, in a cosmetic carrier, at least one reducing agent.
Surfactant treatment is defined as the action on keratinous fibers of a surfactant-comprising cosmetic agent comprising, in a cosmetic carrier, at least one surfactant, preferably an anionic surfactant.
The cosmetic agent comprising a combination of two selected silicones is preferably used immediately after oxidative, reductive and/or surfactant treatment. For the purposes of the present disclosure, after the oxidative, reductive or surfactant treatment is understood to mean an application which either directly follows the oxidative, reductive or surfactant treatment of keratinous fibers, the cosmetic agent being applied to the keratinous fibers, which are preferably still wet and towel-dry, after the oxidative, reductive or surfactant agent has been rinsed off, or being applied to the wet keratinous fibers only after several hours. The cosmetic agent can be rinsed out again after an exposure time of a few seconds up to 45 minutes, or it can remain completely on the keratinous fibers. It is preferred that the cosmetic agent is rinsed with water after the exposure time.
