Patent Application
20150272865
The present invention generally relates to compositions for treating keratinic fibers, in particular human hair, which in addition to the conditioning properties and the luster and feel of keratinic fibers, in particular in particular human hair, have an improved effect, compared to compositions of the prior art, with regard to the removal of dandruff on the keratinic fibers.
The control of dandruff is an important aspect in hair and scalp treatment. In general, anti-dandruff treatment is understood to mean the control of the Pittosporum ovale yeast fungus, which in the case of heavy outbreaks is the cause of cosmetic dandruff. Zinc pyrithione, climbazole, Octopirox, ketoconazole, selenium disulfide, and selenium-containing plant oils, and extracts have proven to be effective anti-dandruff active substances.
Possibly as the result of formation of resistance or due to other influences such as stress, nutrition, and other hair treatments, in particular oxidative hair treatments, it is increasingly the case that the consumer is not satisfied with the available anti-dandruff agents. This may be due to environmental influences and frequent oxidative hair treatments. These influences frequently result in less satisfactory combability of dry and wet keratinic fibers, in particular human hair, and reduced luster. Another consequence of repeated treatments of keratinic fibers with surfactant agents and/or oxidative agents is intense greasiness of the keratinic fibers and a pronounced tendency toward increased formation of dandruff.
It is therefore desirable to provide novel hair treatment agents having increased effectiveness against dandruff, which do not have the described disadvantages of the prior art.
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 background of the invention.
Cosmetic composition that includes in a cosmetic carrier, in each case based on the weight of the overall composition, a) at least one anti-dandruff active substance in a total quantity of 0.01 to 10.0% by weight, selected from zinc pyrithione, climbazole, Octopirox, ketoconazole, selenium disulfide, selenium-containing plant oils, and selenium-containing plant extracts and the mixtures thereof; and at least one sugar structure-containing silicone of the following formula:
in which the radicals R1, R2, and R3 independently stand for a methyl, ethyl, propyl, isopropyl, hydroxy, methoxy, or ethoxy group, x, y, and z in each case stand for an integer from 1 to 1000, and n and m in each case independently stand for an integer from 1 to 100, in a total quantity of 0.01 to 5.0% by weight.
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.
It has now surprisingly been found that the above-described objectives are achieved in a very satisfactory manner by a hair treatment agent which includes an active substance complex that includes as essential ingredients at least one anti-dandruff active substance and at least one selected cationic silicone. Hair treatment agents that include this active substance complex result in improved finish, enhanced luster, improved moisture balance, protection from oxidative damage, prevention of greasiness of the keratinic fibers, increased wash resistance of dyed keratinic fibers, in particular human hair, and in particular a reduction in the formation of dandruff.
A first subject embodiment of the present invention relates to a hair treatment agent that includes in a suitable cosmetic carrier, in each case based on the overall composition of the agent,
in which the radicals R1, R2, and R3 independently stand for a methyl, ethyl, propyl, isopropyl, hydroxy, methoxy, or ethoxy group, x, y, and z in each case stand for an integer from 1 to 1000, and n and m in each case independently stand for an integer from 1 to 100, in a total quantity of 0.01 to 5.0% by weight.
Use of this combination results in surprisingly good properties of the treated hair, in particular improved combability, enhanced luster, and improved elasticity, as well as greatly increased wash resistance of dyed hair, and longer durability, while at the same time providing better shaping capability for perming processes such as water wave and permanent wave. In particular, however, the occurrence of dandruff is greatly retarded by this composition.
In the sense of the present invention, hair treatment agents are understood to mean, for example, hair shampoos, hair conditioners, conditioning shampoos, hair rinses, hair masks, hair packs, hair tonics, hair dye shampoos, or combinations thereof. In particular, the hair conditioning compositions such as hair rinses, hair masks, hair packs, hair oils, and hair lotions, as well as leave-on products, i.e., products that remain on the hair until the next hair washing, and also rinse-off products, i.e., products that are to be rinsed out a few seconds to several hours after application, are understood as the hair treatment agents according to the invention.
According to the invention, combability is understood to mean the combability of wet fibers as well as the combability of dry fibers.
“Hold” is defined as the tactility of a collection of fibers; the parameters of volume and smoothness are felt and assessed by sensory means by those skilled in the art.
Shaping is understood to mean the capability of imparting a change in shape to a collection of previously treated keratin-containing fibers, in particular human hair. In hair cosmetics, this is also referred to as stylability.
In the sense of the invention, restructuring is understood to mean a reduction in the damage to keratinic fibers resulting from various influences. Restoration of the natural strength plays an important role here. Restructured fibers are characterized by enhanced luster, improved hold, and better combability. In addition, they have greater strength and elasticity. Moreover, successful restructuring may be physically demonstrated as an increase in the melting point in comparison to the damaged fiber. The higher the melting point of the hair, the stronger the structure of the fiber.
In the sense of the invention, wash fastness is understood to mean the retention of the original coloring with regard to shade and/or intensity when the keratinic fiber is exposed to the repeated effects from aqueous agents, in particular surfactant-containing agents such as shampoos.
In addition, the compositions according to the invention that include the active substance complex according to the invention are characterized by a greatly improved condition of the keratinic fibers with regard to the moisture balance of the keratinic fibers. Furthermore, the active substance complex according to the invention results in considerable protection of the keratinic fibers from the effects of heat, for example during blow drying of keratinic fibers. The protection of the surface of keratinic fibers from the effects of heat is of major importance in particular when straightening irons or hair dryers are used.
Lastly, it has surprisingly been found that the compositions according to the invention result in greatly retarded resoiling of the keratinic fibers.
An aqueous cosmetic carrier includes at least 50% by weight water.
In the sense of the invention, aqueous-alcoholic cosmetic carriers are understood to mean aqueous solutions that include 3 to 70% by weight of a C1-C6 alcohol, in particular methanol, ethanol, or propanol, isopropanol, butanol, isobutanol, tert-butanol, n-pentanol, isopentanols, n-hexanol, isohexanols, glycol, glycerin, 1,2-pentanediol, 1,5-pentanediol, 1,2-hexanediol, or 1,6-hexanediol. The agents according to the invention may additionally include further organic solvents, for example methoxybutanol, benzyl alcohol, ethyl diglycol, or 1,2-propylene glycol. All water-soluble organic solvents are preferred, with water being particularly preferred.

The second mandatory component of the active substance complex is sugar structure-containing silicone of the following formula:
in which the radicals R1, R2, and R3 independently stand for a methyl, ethyl, propyl, isopropyl, hydroxy, methoxy, or ethoxy group, x, y, and z in each case stand for an integer from 1 to 1000, and n and m in each case independently stand for an integer from 1 to 100.
