Description

"Active substance combination and hair treatment agent for dandruff IM"

The invention relates to a cosmetic hair treatment agent based on a specific combination of active ingredients, a method using the means and the use of the means for the prophylaxis, reduction, elimination and alleviation of dandruff on hairy body surfaces.

Skin and hair cleansers, such as those commercially available as liquid soaps, shampoos, shower baths, bubble baths, shower gels, and wash gels, not only must have good detergency, but should also be well tolerated by the skin and hair if used frequently, do not cause excessive defatting or dryness.

An important aspect of hair cleansing and care is the fight against dandruff, because even the slight appearance of dandruff on the scalp or other hairy body regions is considered a sign of lack of care. In addition, dandruff is usually accompanied by itching, which is perceived as disturbing. Itching, on the other hand, causes scratching reactions, which can lead to injuries of the affected skin, which in turn can form the basis for infections and pathogenic agents. The requirements for a cosmetic remedy for dandruff are therefore high, because on the one hand the scalp should be thoroughly and permanently freed of dandruff, and on the other hand, the remedy for hair and scalp should be well tolerated.

Another important requirement is to have the fastest possible effect, so that the above-mentioned chain of disadvantages does not occur at all.

From the literature, a variety of hair cosmetics are known to prevent or reduce dandruff. The choice is usually made in the form of shampoos, lotions or hair lotions.

EP-A-348 015 discloses the use of zinc salts as anti-dandruff agents.

The combination of three conventional and effective antidandruff agents is the subject of EP 1 238 645 B1. Therein are 1 - (4-chlorophenoxy) -1- (1H-imidazolyl) -3,3-dimethyl-2-butanone (INCI name: climbazole), bis (1-hydroxy-2- (1H) -pyridineethionato ) Zinc (INCI name: Zinc Pyrithione) and 1-hydroxy-4-methyl-6- (2,4,4-trimethylpentyl) -2- (1H) pyridinone, 2-aminoethanol salt (INCI name: Piroctone Olamine ) are already combined at low levels of use to produce an antidandruff agent that prevents or reduces the formation of dandruff. A disadvantage of the means of the prior art has been that they were effective against dandruff, but this effect only after frequent use occurred.

Therefore, it was an additional object of the present invention to find a fast dandruff agent that is gentle on the scalp and the hair and does not adversely affect the hair in terms of its combability, its shine and suppleness. In addition, the anti-dandruff effect of known drugs should, if possible, not only be accelerated, but also increased as far as possible.

This object has been achieved by using the antidandruff active ingredient climbazole in combination with a special epsilon-poly-L-amino acid in a composition suitable for use on hairy body surfaces.

Surprisingly, it was found that hair treatment with cosmetic products based on this combination resulted in a significantly faster and more intensive action than conventional compositions.

The invention therefore hair treatment compositions containing - based on their weight - a) 0.0001 to 5 wt .-% E silane poly-L-lysine of the general formula (I)

As the first essential ingredient, the compositions according to the invention contain epsilon-poly-L-lysine, an oligomer or polymer of the natural amino acid lysine, which is also referred to as epsilon-polylysine due to its linkage in epsilon position. This compound leads to an increase in the activity and acceleration of the antidandruff active ingredient, which goes beyond the own antidandruff effect of epsilon-poly-L-lysine.

Alkylpolyglycosides (APG) are nonionic surfactants made entirely from renewable resources (sugar building blocks, predominantly glucose, for example from corn starch and fatty alcohol, for example from coconut oil). Alkyl polyglycosides are accessible by acid-catalyzed reaction (Fischer reaction) of sugars, especially glucose (or starch) or butyl glycosides with fatty alcohols.

Complex mixtures of alkyl monoglucoside (alkyl-α-D- and β-D-glucopyranoside and small amounts of glucofuranoside), alkyldiglucosides (-isomaltosides, maltosides, etc.) and alkyl oligoglucosides (maltotriosides, tetraosides, etc.) are formed. The average degree of polymerization of commercial products whose alkyl radicals are in the range C8-C16 is 1, 2-1, 5.

Hydrophilic emulsifiers preferably form O / W emulsions and hydrophobic emulsifiers preferably form W / O emulsions. An emulsion is to be understood as meaning a droplet-like distribution (dispersion) of a liquid in another liquid under the expense of energy in order to create stabilizing phase interfaces by means of surfactants.

Siloxanes. These siloxanes can be both water-soluble and water-insoluble. Both volatile and nonvolatile siloxanes are suitable, nonvolatile siloxanes being understood as meaning those compounds whose boiling point is above 200 ° C. under normal pressure. Preferred siloxanes are polydialkylsiloxanes, such as, for example, polydimethylsiloxane, polyalkylarylsiloxanes, such as, for example, polyphenylmethylsiloxane, ethoxylated polydialkylsiloxanes and polydialkylsiloxanes which contain amine and / or hydroxyl groups.

Glycosidically substituted silicones.

It is also possible according to the invention that the preparations comprise a plurality of, in particular two, different polymers of the same charge and / or in each case an ionic and an amphoteric and / or nonionic polymer.

The other polymers (G) are contained in the agents according to the invention preferably in amounts of 0.05 to 10 wt .-%, based on the total agent. Amounts of 0, 1 to 5, in particular from 0.1 to 3 wt .-%, are particularly preferred.

Another object of the present invention is a method for the treatment of keratinic fibers, in particular human hair, in which a hair treatment agent according to the invention applied to keratinic fibers and leave there either until the next hair wash (so-called "leave-on" product) or after Exposure time of 30 to 300 seconds rinsed out (so-called rinse-off product) is.

This non-therapeutic cosmetic procedure leads to a reduction of dandruff. In other words, a method of combating dandruff, in which a hair treatment agent containing - based on its weight - a) 0.0001 to 5% by weight of E silone-poly-L-lysine of the general formula (I)

where n stands for integers between 5 and 100,

b) from 0.01 to 10% by weight of climbazole

applied to the hair and scalp and either

rinsed out after a contact time of 5 seconds to 5 minutes or left there until the next hair wash

becomes, a further object of the present invention.

With respect to preferred embodiments of the method according to the invention mutatis mutandis applies to the means of the invention.

The use of epsilon-poly-L-lysines enhances and accelerates the antidandruff effect of climbazole. A further subject of the present invention is the use of epsilon-poly-L-lysine of the general formula (I)

where n stands for integers between 5 and 100,

to increase the effect of climbazole.

Another object of the present invention is the use of mixtures

a) Pol-L-lysine of the general formula (I)

where n stands for integers between 5 and 100, and

b) climbazole

for the treatment of dandruff.
