Abstract

Cosmetic preparations comprising diethylaminoethyl-dextran (I), are new.

Description

Field of the Invention

The invention is in the field of cosmetic preparations and relates to preparations containing them tend dialkylaminoalkyl dextrans as film formers.

State of the art

Natural or synthetic polymers, which in addition to hydro phobes also carry hydrophilic groups to meet the given requirements such as protection from moisture ness and good washability as close as possible. Tough among the most common film formers len copolymers of (poly) vinyl pyrrolidone and vinyl acetate (PVP / VA) [cf. US 5637296A], the apply to the hair and provide the desired firmness. The copolymers are PVP / VA due to their high affinity for keratin as a film former in hair cosmetics in hair sprays and hair consolidate used.

It is disadvantageous, however, that the films brew slightly after drying, especially when they are applied several times and then not only the styling effect is lost, but also damage of the hair can come.

By Lang et al. WO 94/08554 describes means for setting the hair containing at least one Polymer and ethoxylated C12 to C20 fatty alcohols and at least one water-soluble halogen described free organic solvent. These solvents dry your hair in no time desirable and lead to hair embrittlement, they can also irritate the skin call.

EP 155 400 B describes means for strengthening the hairstyle and care of the hair, which in addition to a qua ternized copolymers of vinyl pyrrolidone and dimethylaminoethyl methacrylate, tetraoxyethylene blue contain rylether. EP 331 930 B also describes means for strengthening the hairstyle and care of the  Hair with a copolymer of vinyl pyrrolidone and vinyl imidazole methochloride and tetraoxy ethylene lauryl ether.

The disadvantage of the agents described above, however, is that they become one, especially at high atmospheric humidity can lead to unnatural sticking of the hair. In addition, these funds still show weaknesses the strengthening of the hair. Another disadvantage of the copolymers mentioned in EP-B 155 400 is that comparatively poor combability of the treated hair.

In addition to the classic film formers based on petrochemical raw materials, Polysac charide, especially chitosans are used [cf. DE 26 27 419 C1 and DE 195 24 125 A1]. As renewable raw material are the polysaccharides like chitosans in comparison with PVP / VA- Copolymers are also characterized by their biodegradability and good compatibility. The bad sol However, chitosan in the organic medium complicates sufficient incorporation into kos meticulations.

The object of the invention was to provide alternative biopolymers, which have very good film-forming properties. These biopolymers are said to have good compatibility with surfactants, salts and other auxiliaries, are in a wide concentration range Have it worked into the formulations, either alone or in combination with other film formers can be used more ecologically and economically. Furthermore, they are said to be a good biological cal compatibility and still have the advantages of known polymers such as constant hardness and show elasticity of the film.

Description of the invention

The present invention relates to cosmetic preparations which contain diethylaminoethyl Contain dextran (DEAE dextran) and the use of diethylaminoethyl dextran (DEAE Dextran) as a film former in cosmetic preparations.

Surprisingly, it was found that these dextran derivatives ( Fig. 1) with an average molecular weight of 50,000 to 800,000, preferably 100,000 to 500,000, in comparison to other polymers, can already greatly increase the flexural strength of strands of hair without using them the hardness of the film is adversely affected. Accordingly, the amount of polymer in a hair cosmetic preparation can be drastically reduced in order to achieve the same positive effect of the increased flexural strength and thus an increased stability of the hair.

The dextran derivatives are easily water-soluble, well tolerated with ions and surfactants and can be Work well into the cosmetic preparations. They are characterized by good biological ver indolence.  

Dextran and DEAE dextran

DEAE-dextran ( Fig. 1) is obtained by cross-linking the linear macromolecules of dextran.

DEAE-Dextran-HCl

Dextran is a slimy, high molecular weight, neutral biopolysaccharide that is produced by bacteria from the Genus Leuconostoc (L. mesenteroides and L. dextranicum) extracellularly within 24 hours at 25 ° Sucrose is formed enzymatically.

In addition to the 1.6 link, the 1.3 link also occurs. The mostly high molecular weight native dextran that is made from finally made up of α-D-glucose (glucan), is precipitated with methanol or acetone and purified. Obtained by acid hydrolysis of crude dextran at 100 ° C and subsequent precipitation fractionation fractions with a molecular weight of 40,000-60,000 for clinical use. Enzy The same fractions can be matically by direct biosynthesis with purified dextran saccharase made from low molecular weight dextran and sucrose at pH 5 and 25 ° C.

Dextrans are used as blood plasma substitutes. In addition, dextran is also used in adhesives, Glues, films, paints, detergents, soil conditioners, paper and. Textile finishes, Cosmetics etc. used as well as a stabilizing additive in freeze drying. Dextran derivatives are used as carriers for pharmaceuticals, ion exchangers and molecular sieves, carriers in affinity matography and for immobilizing enzymes.

Dialkylaminoalkyl dextrans are used as adjuvants in pharmacology (WO 9927959), for coating of cell cultures (US 4994388) and for immobilizing enzymes (WO 9005182). Specifically the DEAE dextran serves as a carrier material in gel chromatography (US 3865807) and in Affini chromatography.

The film-forming properties to increase the flexural strength in hair are by Ami nogroups on polysaccharide improved. Dialkylamino groups are particularly suitable as amino groups special dialkylaminoalkyl groups, the alkyl groups advantageously having 1 to 4 carbon atoms.  

DEAE dextrans are said to be present in the agents according to the invention in concentrations of 0.1-10% by weight, preferably 0.5 to 5 wt .-%, particularly preferably 1 to 3 wt .-% based on the total amount of uses cosmetic products.

Dextran derivatives can also be used in mixtures with other film formers. The biopoly mers of the dialkylaminoalkyl dextrans show alone or in combination with PVP / VA copolymers or Chitosan derivatives improved film-forming properties.

Substances used

example 1

To determine the film-forming properties and the influence of DEAE-dextran on the film strength of hair strands (strand length 12 cm, strand mass 1 g, these were with solutions treated by DEAE dextran hydrochloride in different concentrations.

For this purpose, ten concentration mixtures of DEAE-dextran in water of 1 to 10% by weight were made. DEAE-Dextran and treated the hair with these solutions. Then the hair assess strand according to its flexural strength in comparison to the standard of an untreated strand of hair Splits.

To determine the flexural strength, a strand of hair was treated with a test solution between stored two points and in the middle with a weight of 150 g of water (standard = 100%) burdens. The weight was increased until the strand of hair bent and the result relative to Standard specified. The results are summarized in Table 2.

Comparative example

To compare the properties of DEAE-dextran, solutions of commercially available polymers were made and the influence on the flexural strength of hair was also examined.

Ten solutions each of PVP / VA 64 and PVP K 30 of 1-10% by weight in water were prepared and treated the hair as described in Example 1. The influences of polyvinylpyrrolidones in ver Table 2 shows the same as DEAE dextran.  

Table 2

Flexural strength in hair in% after treatment with film formers of different concentrations

A concentration-dependent increased flexural strength can be clearly determined from the experimental data Detect hair in DEAE dextran as a film former. Already at a concentration of 2% by weight compared to PVP / VA there is a significant improvement of approx. 70%. At a 5% by weight, the bending strength of PVP / VA is approx. 80% and that of DEAE dextran by over 150% higher at approx. 250%. The bending strength increases in the examined concentration range linear for all investigated film formers. This shows in comparison to conventional film formers Hair a more comfortable, elastic and softer handle.
