Description

  The present invention relates to cleaning compositions.

Currently, products different from cleaning agents for washing the body and hair are generally being developed. This is because both the cleaning agent for washing the body and the cleaning agent for washing the hair require foaming and detergency, but different performances are required for the feel to be used. Specifically, a cleansing agent for washing the body is required to have a refreshing feel by quickly rinsing and obtaining a squeaky feeling, whereas a washing agent for washing hair is rinsed from the time of washing. Also, smooth feel and finger passage are required until after towel drying.
For this reason, for example, even if it is a cleaning composition containing polyoxyethylene alkyl ether sulfate, as described in Patent Document 1, a hair cleaning agent does not have a squeaky feeling when rinsing, and has good finger passage. On the other hand, as described in Patent Literature 2, a skin cleansing agent that quickly gives a frictional feel (stop feeling) during rinsing has been developed.
By the way, in recent years, with changes in lifestyle, there has been a need in the morning for a short time in the morning from the head to the body with a shower or the like, and the need to easily clean hair and body with a single cleaning agent. ing. In order to respond to this, for example, in Patent Document 3, a specific fatty acid, an alkyl ether carboxylic acid, and , A composition containing an alkyl sulfate in a specific ratio is disclosed.

International Publication No. 2011/059063 JP 2009-263289 A JP 2014-091815 A

  However, even with the composition of Patent Document 3, when the whole body is washed off in the shower, the body is refreshed without being slimy, but the hair is affected by differences in the length, density, thickness, etc. of the hair. During the rinsing, the finger passed poorly during rinsing, and the hair sometimes became entangled. As a result, it is difficult for water to enter between the hairs during rinsing, and there is a case where rinsing remains.

  According to the present invention, when rinsed after washing, the body quickly feels a stop feeling and the washed skin is refreshed, and at the same time, the hair has a smooth finger passage during rinsing, while rinsing hardly occurs. The end relates to a cleaning composition that gives a refreshing feel.

The present inventors apply the skin cleansing agents of Patent Documents 2 and 3 to the skin and hair and rinse the skin, shower water is applied to the skin to quickly generate scum on the skin surface, and the skin is free of slime. On the other hand, on the hair, the scum is generated quickly near the surface of the hair where shower water is directly applied, so that the hairs are entangled with each other, and the water is less likely to be splashed near the root where the hairs are densely packed. It was presumed that the rinsing property had deteriorated, and the enthusiastic study was conducted.

The results are shown in Table 2. In addition, potassium hydroxide was added in an appropriate amount so that the pH became 9.1 to 9.4. Further, the content of each component shown in Table 2 indicates an amount (effective component) converted as a 100% concentration.

(Production method)
48% potassium hydroxide was added to the component (E), and the mixture was heated to 75 ° C. The components (A) to (D) were dissolved in the aqueous solution at 70 ° C., and a mixed liquid was added thereto, followed by stirring until the mixture became uniform. Thereafter, components (F) and (G) were added as required, and the mixture was stirred until it became uniform, and then cooled to 25 ° C. to obtain a detergent composition.

(Evaluation method)
(1) Detergency:
2% by mass of carbon black was added to a model sebum having the composition shown in Table 1, heated and mixed to make uniform, and then cooled.
20 μg of the model sebum was applied to the forearm to a size of about 3 cm in diameter and left for 30 minutes. Thereafter, a glass cup having a diameter of about 3 cm was attached on the model sebum, and 5 mL of each detergent composition diluted 60-fold with ion-exchanged water was placed in the cup and allowed to stand for 1 minute. Thereafter, the cleaning composition and the cup were removed, and the composition was dried as it was for 5 minutes. The skin color of the model sebum was determined by measuring the skin color (E0) before applying the model sebum, the skin color (E1) to which the model sebum was applied, and the skin color (E2) after washing with a color difference meter (CR-300). , Manufactured by Konica Minolta Co., Ltd.), and the cleaning rate (ΔE (%)) was determined from these colors by the following equation.
This operation was performed three times, and the average value was obtained.

Skin color before applying model sebum: E0 (L0, a0, b0),
Skin color after applying model sebum: E1 (L1, a1, b1),
Skin color after washing: E2 (L2, a2, b2),
ΔE01 = √ ((L0−L1) ² + (a0−a1) ² + (b0−b1) ² )
