preparation example Construction

[0033] Preparation of green tea polysaccharides: solvent extraction of ground green tea powder to remove chlorophyll and low-molecular-weight polyphenols, hot water leaching to obtain green tea polysaccharide extracts, concentration of the extracts under reduced pressure, removal of the polysaccharides by ultrafiltration low molecular weight free protein, precipitate green tea polysaccharide, and vacuum dry the precipitate to obtain green tea polysaccharide powder. Preparation of hinoki polysaccharide: adding water to dry hinoki leaves for extraction, concentrating the extract under reduced pressure, removing low molecular weight free protein therein through ultrafiltration, precipitating hinoki polysaccharide, and vacuum drying the precipitate to obtain hinoki polysaccharide powder.

Embodiment

[0075] Examples and experiments will now be described. The following examples and experiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0076] Preparation Example

[0077] (1) Preparation of green tea polysaccharide

[0078] Green tea polysaccharides were prepared by solvent extraction as follows. Grind and sieve dried green tea leaves. The prepared green powder (d50=100-100 μm, 10 kg) was dissolved in 95% (v / v) ethanol (150 L) and stirred at room temperature. The prepared solution is centrifuged to recover the green tea residue after removal of chlorophyll and low molecular weight polyphenols. The recovered green tea residue was subjected to one more run through the solvent extraction method described above and then dried. Water (125 L) was added to the obtained green tea powder after removal of chlorophyll and low molecular weight polyphenols, and then stirred at 35° C. for 7 hours for hot water extraction.

[0104] Experimental example 1: Confirmation of the effect of reducing stimulation by group test

[0105] In order to confirm the effect of alleviating scalp irritation, a test was conducted on people whose hair was difficult to dye due to irritation.

[0106] Divide 36 people into 9 groups. Each group (4 persons) was dyed with each of the hair dye compositions of Examples 1-9. They were then questioned to assess the degree of improvement in stimulation. As a control group, the composition of Comparative Example 1 and the second reagent (color developer) were used.

[0107] Each of the compositions of Examples 1-9 was mixed with the developer of Table 2 at a ratio of 60 g:60 g. Color your hair for 30 minutes.

Abstract

Disclosed is a composition for oxidative dyeing of keratin fibers. The composition for oxidative dyeing contains one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis. The natural materials included in the hairdye composition are effective in alleviating irritations of the scalp and provide good feeling with characteristic odor. Further, the composition has superior dyeing performance and color persistence and minimizes hair damage. Accordingly, men and women of all ages may safely and conveniently dye their hair to conceal gray hairs or to express their individualities.

Description

technical field [0001] The present invention relates to a composition for oxidative dyeing of keratin fibers, more particularly, to a composition for oxidative dyeing of keratin fibers containing one or more natural substances selected from the group consisting of green tea polysaccharide, cypress polysaccharide, peony, lotus root , Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis. Background technique [0002] In modern society, men and women of all ages dye their hair to hide gray hair or to express their individuality. However, some people are allergic to oxidative hair dyes and cause skin swelling or scalp ulceration. Additionally, people with sensitive scalps can experience scalp irritation, itching, or inflammation. [0003] Hair dyes are divided into permanent hair dyes, semi-permanent hair dyes, temporary hair dyes and other hair dyes according to their color persistence time. [0004] Permanent hair dyes are generally "oxidative hair d...
