The present invention generally relates to compositions for the treatment of keratinic fibers, in particular human hair, that significantly improve the conditioning properties and also the shine and feel of keratinic fibers, in particular human hair, as compared with prior-art compositions. The compositions according to the invention include as essential ingredients cationic ammonium compounds, amidoamines, ester oils, cationic polymers and sugar surfactants.
The cosmetic treatment of keratinic fibers, in particular human hair, is an important element of human body care. Thus human hair is now treated in many different ways with hair cosmetics preparations.
There is still a demand for active ingredients or for combinations of active ingredients for cosmetic agents having good care properties and good biodegradability. The acceptability of the cosmetic compositions is moreover an exceptionally important criterion.
Compositions for use on keratinic fibers, in particular human hair, must not only have a good cleaning, conditioning and care ability but must moreover be well tolerated and not lead to severe degreasing or dryness and split ends, even in frequent use. The feel of the keratinic fibers after cosmetic treatments is an essential criterion in whether the corresponding composition is perceived as pleasing by the consumer. The sensory quality and in particular the feel of a composition are thus essential effects that the consumer can experience. The aim is therefore to find precisely those compositions which not only care for keratinic fibers, in particular human hair, but moreover through their sensory and in particular tactile qualities bring about a tangible and perceptible change in the surface of keratinic fibers, in particular human hair. In particular, the compositions should moreover regenerate and balance out the structure inside the keratinic fibers, in particular human hair. At the same time the compositions should be simple and inexpensive to produce.
Quite unexpectedly, however, it has now been found that a cosmetic composition that includes, in a cosmetic carrier,
The use of this combination leads to surprisingly good properties in the treated hair, in particular to improved combability, to improved shine and to an improved elasticity as well as to a marked increase in the washing resistance of colored hair and to a longer hold combined at the same time with a better shaping performance in waving processes such as finger waving and permanent waving.
Furthermore, other desirable features and characteristics of the present invention will become apparent from the subsequent detailed description of the invention and the appended claims, taken in conjunction with the accompanying drawings and this
A cosmetic composition for conditioning keratinic fibers, including in a cosmetic carrier: a) 0.1 to 6.0 wt. % of at least one cationic surfactant selected from behentrimonium chloride and/or dimethyl dibehenyl ammonium chloride and/or tribehenyl methyl trimonium chloride and/or cetyl trimethylammonium chloride and/or dicetyl dimethylammonium chloride and/or tricetyl methylammonium chloride and/or trimethyl stearyl ammonium chloride, dimethyl distearyl ammonium chloride and/or tristearyl methylammonium chloride and mixtures thereof; b) 0.01 to 6.0 wt. % of at least one amidoamine and/or one permanently cationic amidoamine; c) 0.01 to 7.5 wt. % of at least one ester oil; d) 0.01 to 5.0 wt. % of at least one cationic polymer selected from Polyquaternium-67 and/or Polyquaternium-72 and/or Polyquaternium-74 and/or Polyquaternium-37; and e) 0.001 to 3.0 wt. % of at least one sugar surfactant, all stated amounts relating to the total weight of the cosmetic composition.
The following detailed description of the invention is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description of the invention.
Hair treatment agents within the meaning of the present invention are for example hair shampoos, hair conditioners, conditioning shampoos, hair rinses, hair masks, hair packs, hair tonics, hair coloring shampoos or combinations thereof. In particular, the hair treatment agents according to the invention are understood to be hair conditioning compositions such as hair rinses, hair masks, hair packs, hair oils and lotions, both as leave-on products, i.e. products that remain on the hair until the next time it is washed, and as rinse-off products, i.e. products that are rinsed out again a few seconds up to a few hours after application.
According to the invention combability is understood to mean both the combability of wet fibers and the combability of dry fibers.
Feel is defined as the tactility of a group of fibers, the person skilled in the art feeling and assessing the parameters fullness and softness of the group of fibers by sensory means.
Shaping is understood to be the ability to change the shape of a group of previously treated keratin-including fibers, in particular human hair. In hair cosmetics this is also referred to as styleability.
Restructuring within the meaning of the invention is understood to be a reduction in the damage that is caused to keratinic fibers by a very wide variety of influences. The restoration of natural strength, for example, plays an important part in this. Restructured fibers are characterized by an improved shine, an improved feel and easier combability. They also have improved strength and elasticity. Furthermore, a successful restructuring can be physically detected as an increase in the melting point in comparison to damaged fibers. The higher the melting point of the hair, the stronger the structure of the fiber.
Wash fastness within the meaning of the invention is understood to be the retention of the shade and/or intensity of the original color when the keratinic fiber is exposed to the repeated influence of aqueous agents, in particular surfactant-including agents such as shampoos.
The compositions according to the invention including the active ingredient complex according to the invention are characterized moreover by a markedly improved condition of the keratinic fibers in terms of the moisture balance of the keratinic fibers. Furthermore, the active ingredient complex according to the invention leads to a marked protection of the keratinic fibers against the effects of heat, for example when blow-drying keratinic fibers. Protecting the surface of keratinic fibers against the effects of heat is very important, particularly when using hair straighteners or hair dryers. Finally, it was established that the compositions according to the invention surprisingly lead to a marked lengthening of the time taken for the keratinic fibers to become dirty again.
An aqueous cosmetic carrier includes at least 50 wt % of water.
Within the meaning of the present invention aqueous-alcoholic cosmetic carriers are understood to be aqueous solutions including 3 to 70 wt. % of a C1-C6 alcohol, in particular methanol, ethanol or propanol, isopropanol, butanol, isobutanol, tert-butanol, n-pentanol, isopentanols, n-hexanol, isohexanols, glycol, glycerol, 1,2-pentanediol, 1,5-pentanediol, 1,2-hexanediol or 1,6-hexanediol.
