Abstract

Antidandruff shampoos containing an effective amount of extracts of Camellia sinensis or their active substances of the polyphenol type, in particular catechins, and / or flavonoids are proposed.

Description

Field of the Invention

The invention is in the field of hair treatment compositions and relates to new ones Antidandruff shampoos with an effective content of special plant extracts or their active ingredients and their use in the preparation of the compositions.

State of the art

The cosmetic chemist understands the term dandruff, more precisely: dandruff Parts of the horny layer of the skin that are part of the constant renewal of the skin layers be repelled. They are on the hairy head due to their adhesion by sebum and Perspiration to larger aggregates is particularly visible. A cosmetically disruptive Flaking is counteracted by treating the scalp with anti-dandruff agents that usually in special hair treatment products, so-called anti-dandruff shampoos be applied. Selenium disulfide, for example, Pyrethione salts, shale oils and other microbicides are used, which they have in common have skin irritating properties, have an undesirable intrinsic odor and / or only are difficult to incorporate into the wording.

The object of the present invention was therefore to create new ones To provide anti-dandruff shampoos that are free from the disadvantages mentioned at the beginning. In particular, the active ingredients should be of a vegetable nature and not chemically derivatized, do not cause irritation, free of annoying smells and be easy to formulate and, of course, reliably prevent or prevent unwanted dandruff formation reduce to a dimension that is no longer disturbing.

Description of the invention

The invention relates to antidandruff shampoos containing an effective amount of Extracts of Camellia sinensis or their active substances of the catechin type and / or Flavonoids.

Surprisingly, it was found that preparations that act as extracts of the Camellia sinensis and its active principles (polyphenols, especially catechins, and / or flavonoids), the scaling on the scalp so far reliable prevent that it is no longer annoying. The active ingredients are of natural origin, not further chemically modified, odorless and can be easily incorporated into the formulations incorporated.

Extracts from Camellia sinensis

Camellia sinensis is green tea which contains as active ingredients ("tea tannins), essentially polyphenols, namely epicatechin, epigallocatechin, epigallocatechin gallate, epigallocatechin gallate, theaflavin, theaflavin monogallate A or B and theaflavine digallate which contains itself Find extracts.

As a rule, the freshly dried tea leaves have a catechin content of 20 to 25% by weight of which the epigallocatechin gallate alone makes up about 50 to 70% by weight. So are preferred agents that have this active ingredient in particularly high concentrations.

The extracts can be prepared in a manner known per se, i. H. for example by aqueous, alcoholic or aqueous-alcoholic extraction of the plants or Parts of plants or leaves or fruits. All conventional ones are suitable Extraction processes such as B. maceration, remaceration, digestion, movement maceration, vertebral extraction, Ultrasonic extraction, countercurrent extraction, percolation, repercolation, evacolation (Extraction under reduced pressure), diacolation or solid liquid extraction under continuous reflux. The percolation method is advantageous for large-scale use. Fresh plants or parts of plants can be used as starting material, Usually, however, it is assumed that the plants and / or parts of plants are dry can be mechanically crushed before extraction. All are suitable for this Comminution methods known to those skilled in the art, freeze grinding may be mentioned as an example. Organic solvents, Water (preferably hot water at a temperature above 80 ° C and especially from above 95 ° C) or mixtures of organic solvents and water, in particular low molecular weight alcohols with more or less high water contents can be used. Extraction with methanol, ethanol, pentane, hexane, heptane is particularly preferred. Acetone, propylene glycols, polyethylene glycols and ethyl acetate and mixtures thereof as well as their aqueous mixtures. The extraction usually takes place at 20 to 100 ° C, preferably at 30 to 90 ° C, especially at 60 to 80 ° C. In a preferred embodiment the extraction takes place under an inert gas atmosphere to avoid oxidation of the active substances of the extract. This is particularly the case for extractions at temperatures above 40 ° C Importance. The extraction times are dependent on the person skilled in the art Starting material, the extraction process, the extraction temperature, the ratio of solvent to Raw material u. a. set. After extraction, the crude extracts obtained optionally further conventional steps, such as purification, concentration and / or Undergo discoloration. If desired, the extracts so produced for example, a selective separation of individual undesirable ingredients become. The extraction can be done to any degree of extraction, but will usually done to exhaustion. Typical yields (= amount of dry matter of the extract based on the amount of raw material used) when extracting dried leaves are in the range from 1 to 25, in particular 2 to 22,% by weight. The present invention includes the knowledge that the extraction conditions and the yields of the Final extracts can be selected by the specialist depending on the desired area of application. This Extracts, which are generally active substance contents (= solids contents) in the range from 0.5 to 25% by weight can be used as such, but it is also possible that Solvent by drying, especially by spray or freeze drying to be removed completely, leaving an intensely red solid. The extracts can also serve as starting materials for the production of the above-mentioned pure active ingredients, provided that these are not manufactured more easily and cost-effectively by synthetic means can. Accordingly, the active substance content in the extracts can be 5 to 100, preferably 50 amount to 98% by weight. The extracts themselves can be aqueous and / or organic Preparations dissolved in solvents and as spray-dried or freeze-dried, water-free Solids are present. In this connection come as organic solvents for example the aliphatic alcohols with 1 to 6 carbon atoms (e.g. ethanol), ketones (e.g. Acetone), halogenated hydrocarbons (e.g. chloroform or methylene chloride), lower esters or polyols (e.g. glycerin or glycols) in question.
