Patent Application
20190183764
This application claims priority to German Patent Application No. 10 2017 223 103.3, filed Dec. 18, 2017, which is incorporated herein by reference in its entirety.
The present disclosure relates to hair treatment agents having improved rheology and conditioning properties, and which contain amidoamines and sulfated or sulfonated oils in an aqueous or aqueous-alcoholic carrier.
The present disclosure further relates to a method for the production of a hair treatment agent—for example an O/W hair care emulsion.
Frequently repeated bleaching, perming and/or dyeing, but also frequent washing of the hair, frequently leads to varied damage to the hair structure. The hair becomes brittle and loses its shine due to this. In addition, it is electrostatically charged when combing and the roughened hair surface causes matting and knotting of the hair. Combing is made more difficult and can result in too much loss of hair.
To avoid these disadvantages, consumers are advised to use a care product after the aforementioned hair treatment methods.
Nurturing hair treatment agents have long been known and are usually offered in the form of clear hair care rinses or in emulsion form, so called “cream rinses”. They provide stressed hair with care ingredients and give the hair suppleness, shine and improved combability again.
Nurturing hair care agents usually contain cationic surfactants, cationic polymers and fatty alcohols as active ingredients for improving the hair structure, usually also polymeric thickening agents and silicones.
Due to the increasing numbers of incompatibilities, it is desirable to provide hair care agents of low complexity and high quality.
An object of the present disclosure was to provide stable hair treatment agents having excellent rheology and care properties, and which contain the smallest possible number of different classes of active ingredients and whose technical production causes no problems. An object of the present disclosure was further to find a method by which an exact product rheology can be ensured. In addition, the rheological properties of the products should essentially not change after their production.
It has been found that a hair treatment agent which contains amidoamines and sulfated or sulfonated oils is outstandingly suitable for this purpose.
A first subject of the present disclosure is therefore a hair treatment agent, that contains
a) from about 0.5 to about 10.0% by weight of amidoamine,
b) from about 0.1 to about 10.0% by weight of sulfated or sulfonated oil and
c) an aqueous or aqueous-alcoholic carrier,
wherein the amount specifications are based on the weight of the entire agent.
The combination of these active ingredients in hair treatment agents, preferably in hair care agents and in particular in hair care emulsions, can significantly improve the rheological properties of the agents.
The viscosity is usually adjusted with polymeric thickening systems in the production of conventional hair care emulsions. The addition of polymeric compounds and/or ethoxylated stabilizers is not required in the production of the compositions according to present disclosure, making them technically simpler, more convenient and more economical.
In addition, the agents as contemplated herein impart improved combability to treated hair and a noticeably reduced static charge and reduced hair breakage.

Such products are sold, for example, under the names Stepantex®, Dehyquart®, Armocare® and Quartamin®.
In one embodiment, in the event that the hair treatment agent as contemplated herein is formulated as a care rinse (hair care emulsion), it is suitable when they additionally contain at least one cationic surfactant in a weight fraction from about 0.01 to about 10.00% by weight, for example from about 0.05 to about 8.00% by weight, such as from about 0.10 to about 6.00% by weight and in one embodiment from about 0.50 to about 5.00% by weight, wherein the amount specifications are based on the entire weight of the hair treatment agent.
The hair treatment agents as contemplated herein can be provided in a wide pH range. They have excellent stability in this pH range.
In a further embodiment, the hair treatment agents as contemplated herein have a pH in the range from about 2.8 to about 8.0, for example from about 3.0 to about 7.0, such as from about 3.2 to about 6.0 and in one embodiment from about 3.4 to about 5.0.
A further object of the present disclosure was to provide hair treatment agents, for example in the form of an O/W hair care emulsion, which have a pleasant consistency, that is, can be easily removed from a suitable container and spread on the hair without dripping or sticking too strongly on the hair.
It has been found that this goal can be achieved with the help of the combination of active substances as contemplated herein, because, unlike the use of polymeric thickening agents, the emulsion can be produced and then just adjusted to the desired viscosity. This subsequently results in very little increasing viscosity, whereby specifications can be narrowed down.
Suitable hair treatment agents according to the present disclosure have a viscosity in the range from about 4,000 to about 15,000 mPas.
In a further embodiment, hair treatment agents as contemplated herein have a viscosity in the range from about 4,000 mPas to about 15,000 mPas, for example from about 5,000 mPas to about 14,000 mPas, for example from about 6,000 mPas to about 13,000 mPas and in one embodiment from about 7,000 mPas to about 12,000 mPas (determination after about 1 minute with Brookfield viscometer; Spindle 5; about 20° C.; about 20 rev/min).
In a further embodiment, hair treatment agents as contemplated herein are in the form of an O/W emulsion.
As already stated, it is not necessary for the production, viscosity adjustment and/or stabilization of the hair treatment agents as contemplated herein that polymeric thickening agents and/or alkoxylated emulsifiers be added to them.
In a further embodiment, hair treatment agents as contemplated herein are therefore essentially free of alkoxylated emulsifiers or surfactants.
In a further embodiment, therefore, hair treatment agents as contemplated herein are substantially free of polymeric thickening agents of synthetic and/or natural origin.
In a further embodiment, hair treatment agents as contemplated herein are also substantially free of silicones.
“Substantially free” is understood to mean a content of at most about 0.1% by weight, for example at most about 0.05% by weight and in one embodiment about 0.01% by weight (based on the entire weight of the agent), wherein the respective content relates to freely added proportions of alkoxylated emulsifiers or surfactants and to freely added polymeric thickening agents of synthetic and/or natural origin. Commercial product mixtures in which the aforementioned ingredients in certain circumstances may possibly be present in minor amounts are not included.
In addition to the constituents and the aforementioned optional active substances, the hair treatment agents as contemplated herein can contain further active substances, auxiliaries and additives which can be selected from:
and further from
With regard to further optional components and the amounts of these components used, reference is made to the relevant manuals known to one skilled in the art.
A second subject of the present disclosure is the cosmetic use of the hair treatment agent as contemplated herein for the care of hair, in particular for
improvement of wet and dry combability,
reduction of static charges and
reduction of hair breakage.
A third subject of the present disclosure is the use of
a) from about 0.5 to about 10.0% by weight amidoamine and
b) from about 0.1 to about 10.0% by weight sulfated oil
in an aqueous or aqueous-alcoholic vehicle for improving the rheological properties of hair treatment agents, in particular hair care emulsions.
A fourth subject of the present disclosure is a cosmetic method for the care of keratinic fibers, in particular human hair, in which a hair treatment agent as contemplated herein is applied to preferably wet keratinic fibers, preferably after hair cleaning, and optionally rinsed again after an exposure time of from about 5 seconds to about 5 minutes.
A fifth subject of the present disclosure is a cosmetic method for the production of a hair treatment agent, preferably an O/W care emulsion, in which
What has been stated for the agents as contemplated herein applies accordingly for the uses as contemplated herein and the methods as contemplated herein.
a) The Following Hair Treatment Agents as Contemplated Herein were Produced (all Amount Specifications are in % by Weight):
b) Proofs of Effect
Six hair care agents were produced, each once with a content of sulfated oil and once without a content of sulfated oil, which in four cases contained cationic surfactants (alkyl quats and alkyl esterquats) rather than an aminoamine.
Neither with the alkyl quat (cetyltrimethylammonium chloride) alone nor in combination with a sulfated oil was it possible to achieve a viscosity in the stated range (see above).
The use of an esterquat (distearoylethyl hydroxyethylmonium methosulfate) instead of an alkyl quat (also in combination with sulfated oils) resulted in higher viscosity values, but the combination of an amidoamine with a sulfated oil was most effective.
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.
