JPS59101412A - Hair-protecting cosmetic composition containing crude drug - Google Patents

Abstract

PURPOSE:To provide the titled cosmetic composition effective to suppress the separation of amino acid caused by the damage of hair, by compounding the extract of crude drugs such as OGON (root of Scutellaria baicalensis), JIO (root of Rehmannia glutinosa), BANKEISHI (fruit of Vitex rotundifolia) etc. CONSTITUTION:The objective composition contains 0.1-10wt%, preferably 1- 5wt%, based on the whole composition, of the extract of a crude drug selected from OGON, JIO, BANKEISHI, SOKAKUSHI (thorn of Gleditsia sinensis), SANYAKU (Rhizome of Dioscorea batatas), GOSHITSU (root of Achyranthes bidentata), JUTSU, MASHININ (fruit of Cannabis sativa) and SHIN-I (bud of Magnolia fargesii). The extract can be obtained by chopping dried crude drug to fine strips, extracting the drug with water, a lower alcohol or their mixture (preferably 30-50% ethanol aqueous solution) at 60-100 deg.C for 1-3 hours or at room temperature for 2-3 days (if necessary, repeating the process twice- several times), filtering the extract, and concentrating and drying the filtrate at 40-60 deg.C under reduced pressure.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to hair protection cosmetic compositions containing crude drugs, more specifically, bleaching, perming, hair dye, shampoo,
The present invention relates to a cosmetic composition for hair protection containing a crude drug that protects and repairs hair damaged by heat from a dryer, ultraviolet rays, flaking, flashing, etc.

Conventional technology Hair suffers from damage to its surface structure, destruction of internal proteins, and release of amino acids due to UV rays from sunlight, heat from dryers that have become popular in recent years, and treatments such as bleaching, perming, and hair dye. The hair is severely damaged, and the hair's natural moisture retention, alkali resistance, elasticity, strength, etc. are reduced. As a result, the hair becomes dry, loses its moist feel and luster, causes split ends and fissures, and also has poor texture and combability.

Such protection and repair of hair damage is achieved by using cosmetics containing various hair protectants and by adsorbing the hair protectant to the hair to cover the surface or fill in damaged areas. For example, conventionally, cosmetics containing cationic substances such as cationic polymers as hair protectants have been used.
The polymer is adsorbed onto the hair or polymerized into the hair defect, or the hair surface is coated with oil using a cosmetic with a high oil content to prevent moisture from evaporating. On the other hand, in recent years, from the perspective of improving the safety of cosmetics, there has been a growing trend to use natural products as ingredients. Natural products or substances derived from natural products, such as natural oils and fats, are increasingly being used.

However, compared to cationic substances, such substances have the disadvantage that they are weakly adsorbed to hair and are less effective.

Purpose of the Invention In view of the above circumstances, the present inventor has made efforts to obtain a hair protection cosmetic that uses a hair protection agent that is a natural product or a substance derived from a natural product and exhibits a hair protection effect. investigated. As a result, it was surprisingly discovered that certain herbal medicines have an excellent effect on protecting hair, that is, suppressing the release of amino acids due to hair damage. They discovered that it is possible to obtain a hair protection cosmetic that exhibits a smoothing effect, and have completed the present invention.

Structure and Effects of the Invention In other words, the present invention provides one or more species selected from the group consisting of Orifolia, Jihuang, Manjingzi, Bekakutashi, Mountain medicine, Gyuhitsu, Oni, Mazijin, and Xinyi. The present invention provides a hair protection cosmetic composition containing extracts from herbal medicines. By using the cosmetics of the present invention as appropriate during daily hair styling, or before and after shampooing, bleaching, perming, hair curling, etc., the cosmetics of the present invention can exert a protective effect on curly hair and keep the hair extremely moisturized. Feeling, being touched,
You can keep the comb straight.

The results of tests on the hair protection effects of various herbal medicine extracts are shown below.

The protective effect can be evaluated based on the extent to which the test substance suppresses the elution of hair components into the alkali-11 solution when the hair is damaged with bleach and immersed in the solution.

Preparation of crude drug extract sample solution 100 g of dried chopped crude drug was added to 30% ethanol aqueous solution 3
The mixture was heated under reflux at 00 mJ for 3 hours and filtered to obtain liquid F.

This operation is repeated once more, and the obtained liquid F is combined and concentrated to dryness. A 1% aqueous solution of this residue (dried extract) is prepared and used as a sample solution.

Preparation of Freech Liquid 20 parts by weight of 30% hydrogen peroxide solution, 1 part of 28% ammonia solution
A bleaching liquid is obtained by mixing parts by weight and 79 parts by weight of purified water.

Preparation of hair Approximately 5 CII p of unbleached human hair was washed with a 1% aqueous sodium lauryl sulfate solution, and after washing with water, 105
Dry at °C for 3 hours and weigh accurately.

Hair treatment: Dry, precisely weighed hair and add 5 ml of sample solution to 30"C.
After soaking for 0 minutes, rinse thoroughly with water and add 5ml of freech solution.
for 30 minutes at 30"C and rinse thoroughly with water (processing 1).
). Alternatively, dry and accurately weighed hair is first treated in the same manner with Freech's solution, and then treated in the same manner with the sample solution (
Processing 2).

Hair treated with alkali elution was soaked in 10ml of 0.1N sodium hydroxide solution.
After soaking at 60°C for 1 hour, wash with water. Furthermore, after washing with a 1% acetic acid solution, it is thoroughly washed with water, dried at 105°C for 3 hours, and its weight is precisely weighed. The ratio to MM before treatment is defined as the rate of elution by alkali (A). Furthermore, the elution rate (Ac) of hair (damaged hair) subjected to the same treatment using the same amount of purified water instead of the sample solution due to alkali is determined. Furthermore, the alkali elution rate (Ab) of hair (undamaged hair) treated using the same amount of purified water instead of Freech's solution is determined. From these values, the loss reduction rate is calculated using the following formula.

Table 1 shows the types of herbal medicines and their damage inhibition rates.

As a control, the results of a similar test using a 1% aqueous solution of collagen hydrolyzate conventionally used as a hair protection agent as a sample solution are also shown.

Table 1 Table 1 (Tsuki) Extracts of horn thorn, mountain medicine, ox hiza, po, mazi jin and xin yi showed a protective effect on curly hair, especially in treatment 2 (recovery of damaged hair after bleaching). , kolachen hydrolyzate do not show any effect, but these herbal medicine extracts show very good effects.

Thus, the cosmetic composition of the present invention contains one of these crude drugs.
Extracts obtained from the species or two or more species are blended. 1st
As shown in the table, from the viewpoint of effectiveness, yellow calyx, manjingzi, wild medicine,

The extract can be obtained by, for example, adding a single item or a mixture of several pieces of dried herbal medicine to water, methanol, ethanol, a lower alcohol such as propatool, impropateur, or a mixed solvent of these. With a solvent like
1-3 hours at 60-100"C or 2-3 hours at room temperature
Extract for 3 days, repeat this operation two to several times if necessary, filter, and concentrate the p solution to dryness, preferably at 40 to 60°C under reduced pressure. It may be used after further purification by known methods such as , solvent fractionation, and chromatography. Usually, as a solvent, 30% to 5
It is preferable to use a 0% ethanol aqueous solution. The amount of the extract can be selected as appropriate depending on the actual net shape, but
Generally, 0.1 to 10% (wt%) based on the total amount of the composition.
The same applies hereinafter), preferably a ratio of 1 to 5% is sufficient to achieve the desired effect.
