Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair shampoo having low irritation, excellent foaming properties, excellent foaming properties, excellent use during washing and after washing, having an appropriate detergency and good stability over time. Composition.

[0002]

BACKGROUND OF THE INVENTION Most hair shampoo compositions contain an anionic surfactant as a main base, and among them, ether sulfate type anionic surfactants are widely used. Ether sulfate type anionic surfactants and amide group-introduced amide ether sulfate type anionic surfactants have the advantage of having relatively high foaming properties, but have comparative irritant properties on the skin and hair. It has the disadvantage of being expensive. Therefore, betaine-type amphoteric surfactants are often used in combination to alleviate this irritation. Examples of these are compositions comprising a combination of an ether sulfate type anionic surfactant, an alkyl betaine or amido betaine type amphoteric surfactant and an acyl neutral amino acid type anionic surfactant (JP-A-11-189515). ), A composition in which an ether sulfate type anionic surfactant is combined with an alkyl betaine or amido betaine type amphoteric surfactant and an acyl glutamate type anionic surfactant (JP-A-11-29446), an ether sulfate type Composition containing a combination of an anionic surfactant and an amidopropyl betaine type amphoteric surfactant

No. 8), a composition comprising a combination of an amide ether sulfate type anionic surfactant, a betaine type amphoteric surfactant and an amino acid surfactant (JP-A-10-1823).
No. 67) and a composition in which an amide ether sulfate type anionic surfactant and a betaine type amphoteric surfactant are combined (JP-A-3-215410).

[0003] However, the foaming of the composition obtained by combining the above-mentioned ether sulfate-type anionic surfactant or amide ether sulfate-type anionic surfactant with a betaine-type amphoteric surfactant and various types of surfactants is comparative. It has the disadvantage of good foam quality but lack of foam sustainability. Further, these hair shampoo compositions have a strong feeling of squeezing when shampooing the scalp and hair after shampooing, and have drawbacks in terms of usability such as poor finger passage. Also, there is a tendency that excessive degreasing from the scalp or the scalp is observed, and there is also a problem that irritation becomes strong and hair is easily damaged when used continuously.

The test solution was applied to the inside of the upper right arm, and purified water was applied to the inside of the left upper arm as a control. After 24 hours from the application, the patch was peeled off, the test portion was washed with 500 ml of purified water, and then rested for 1 hour. After 1 hour, the test portion of the control and the test solution was visually judged. Two points when there was little difference between the control and the test part of the test solution, one point when the test solution showed slight redness compared to the control, and one point when the test solution showed clear redness or edema The following three grades were evaluated based on the total score of the five people, with the case where it was given as 0.

5W), and immersed therein a hair of a healthy 20-year-old man whose virgin hair was cut to 1.5 cm from the base up to 2 cm from the root, and ultrasonically treated at a test solution temperature of 25 to 45 ° C. for 3 hours. Processed. Thereafter, the cross section of the treated hair was observed with an electron microscope, and the number of cuticles was measured. The measurement of the number of cuticles is performed on three hairs by measuring five sites from one hair.
The average of each measurement was determined. The percentage of the number of cuticles of the treated hair with respect to the untreated hair (average number of cuticles: 7.5) was determined, and this was evaluated as a cuticle remaining rate in the following three stages. ：: The cuticle has a high residual ratio (small peeling: the residual ratio is 75% or more).

Then, the artificially stained wool muslin cloth was washed with a Terg-O-tometer under the conditions of 40 ° C., 70 rpm, and 10 minutes. After drying the contaminated cloth, the surface reflectance was measured with a color computer, the detergency was calculated from the following equation, and evaluated in the following three steps. Detergency (%) = A / B x 100 A: (Reflectance of contaminated cloth after cleaning)-(Reflectance of contaminated cloth before cleaning) B: (Reflectance of wool muslin)-(Contamination cloth before cleaning)反射: Good detergency (25% or more and less than 60%). ×: Excessive detergency (60% or more detergency). ×: Detergency is weak (less than 25%).

(8) Finger shampooing for rinsing Hair and shampoo composition 5
The hair and scalp were washed with g, and the finger passage upon rinsing was evaluated. The following three points were obtained from the total score of 20 people, with 2 points when no squeaky feeling was felt, 1 point when the squeaky feeling was strong, and 0 when the squeaky feeling was very strong.
It was evaluated on a scale. ：: Good finger passing (30 points or more in total). Δ: Slightly poor finger passage (total score of 20 or more and less than 30). ×: Bad finger passing (less than 20 points in total).

[Table 4]

From Tables 3 and 4, it can be seen that the cleaning compositions of Examples 1 to 17 of the present invention have low irritation, small cuticle peeling, foaming properties, foam quality, feeling during washing and after washing. It can be seen that this is a cleaning composition having excellent detergency, moderate detergency and good stability over time.

The hair shampoo composition of Comparative Example 1 comprises (a)

Excessive detergency, poor finger stability during rinsing, poor stability over time, and poor hairstyle after drying. Comparative Example 3
Since the hair shampoo composition of (a) is less than 1% by weight, the foaming power, the foam retention rate, the foaming properties, and the detergency are low, and a favorable foam quality cannot be obtained, and finger passing during rinsing is poor. , Hairstyle after drying is not organized. In the hair shampoo composition of Comparative Example 4, since (a) exceeds 35% by weight,
It is highly irritating, has a low cuticle residual rate (large cuticle detachment), has a low foam retention rate, cannot obtain a desirable foam quality, has excessive detergency, and has poor stability over time.

The hair shampoo composition of Comparative Example 5 comprises (b)

Insufficient stability over time as per the finger at the time of rinsing, and the hairstyle after drying is not organized. Since the hair shampoo composition of Comparative Example 8 contains (c) in excess of 10% by weight, it is highly irritating, has a low cuticle residual rate, and has low foaming power, foam persistence and foaming properties, and is therefore preferable. Foam quality cannot be obtained, fingering during rinsing, stability over time is poor, and hairstyle after drying is not cohesive. Since the hair shampoo composition of Comparative Example 9 has a weight ratio of (a) and (b) of less than 1/10, it has strong irritation, a low cuticle remaining rate, foaming power, foam retention rate, and foaming. Poor properties, poor foaming properties, excessive detergency, poor finger rinsing, and poor hairstyle after drying.

Favorable foam quality cannot be obtained, the stability during aging is poor, and the hairstyle after drying is not cohesive. Since the detergent compositions of Comparative Examples 13 and 14 use diethanolamide laurate instead of (c), they are highly irritating, have a low cuticle remaining rate, have a low foam retention rate, and have a favorable foam quality. Is not obtained, the cleaning power is excessive,
The fingers do not pass easily during rinsing, and the hairstyle after drying is not organized. Since the detergent compositions of Comparative Examples 15 and 16 use disodium lauroylglutamate instead of (c), the residual ratio of cuticle is small, the persistence of foam is low, and favorable foam quality cannot be obtained. Excessive detergency, poor finger rinsing and poor hairstyle after drying. Since the detergent composition of Comparative Example 17 uses stearyltrimethylammonium chloride instead of (c), it is highly irritating, has a low cuticle remaining rate, has a low foam retention rate, and has favorable foam quality. Not enough, excessive cleaning power, poor rinsing, poor stability over time, and poor hairstyle after drying
