Description

  The present invention relates to a liquid hair cleaning composition.

  Conventionally, a shampoo mainly composed of a higher fatty acid salt is known, and this is sometimes called a soap shampoo.

  However, shampoos mainly composed of higher fatty acid salts have the property of forming scum by metal salts such as magnesium and calcium contained in tap water, and scum causes squeaking during rinsing and causes poor finger-handling. become.

  Further, although higher fatty acid salts are used in various detergents, for example, Patent Document 1 has drawbacks such as higher fatty acid salts having insufficient foaming and poor stability at low temperatures. It has been reported that as a cleansing agent intended to improve these drawbacks, skin cleansing containing specific crystalline cellulose, polyquaternium-7, higher fatty acid salt having 8 to 22 carbon atoms, and polyhydric alcohol. The fee is listed. Patent Document 1 reports that the skin cleansing agent provides advantages such as excellent foaming and good stability over time.

Evaluation Procedure Each of the prepared compositions was evaluated for foaming, foaming, finger passage when rinsing hair, sliminess after rinsing, and stability at 0° C. (low temperature stability) according to the following procedures. More specifically, the evaluation was performed as follows.

  Human hair bundles (length: 30 cm, thickness: 1.5 cm, weight: 13 g) were washed with 0.5 g of each composition, resulting in foaming, foam retention, finger-passing when rinsing hair, and after rinsing The slimyness was evaluated according to the following criteria. In addition, these evaluations and the evaluation of low temperature stability were based on the results of discussions by three expert panelists.

Bubbling It was visually observed how quickly and large bubbles were formed when bubbling with 38° C. water (tap water), and evaluation was made according to the following criteria. At this time, both ends of the human hair bundle sufficiently wet with 38° C. water were grasped by the hands, and the human hair bundle was swirled on the fist (while sandwiched between both palms) for a total of 20 times to foam.
⊚: Bulky bubbles of 2 cm or more were formed on the entire hair bundle by the time of 10 laps.
◯: At the time when the foaming was completed (20 laps), a foam having a bulk of about 2 cm was foamed over the entire hair bundle.
X: No foam was formed on the entire hair bundle when foaming was completed, or only a foam having a bulk of 1 cm or less was foamed.

Sustainability of the size of the foam, which changes with time, was evaluated according to the following criteria. At this time, as in the procedure for evaluating foaming, the mixture was rotated 20 times for foaming and then left standing for 15 seconds to visually observe the appearance of the foam.
A: No cell breakage was observed even after standing for 15 seconds.
◯: No bubble break was observed for at least 10 seconds.
X: Foaming was observed within 10 seconds.

The smoothness of the surface of the hair bundle when rinsing the human hair bundle that was passed through with fingers when rinsed with water at 38° C. was evaluated according to the following criteria. At this time, after foaming by turning 20 times as in the foaming evaluation procedure, one end of the human hair bundle is pinched with one hand and the whole bundle is put into running water, and the finger of the other hand is used to move the other end to the other end. Rinsing about 20 times (ie, rubbing from top to bottom).
◎: There was no catch on the finger during rinsing, and it was smooth and smooth.
◯: I felt a slight catch on my finger during rinsing.
X: A clear catch was felt during rinsing.

Lubricity after rinsing After rinsing human hair bundles with water at 38°C in the same manner as described above, it was evaluated according to the following criteria whether or not there was any slimyness on the hands or hair.
A: It was not slimy.
◯: I felt a little slimy.
X: I felt quite slimy.

Low temperature stability Stability at 0° C. (low temperature stability) was determined by placing 45 g of the above composition in a 50 mL glass screw bottle (transparent), closing the cap, and leaving it in a constant temperature bath set at 0° C. for 2 months. Then, the presence or absence of a change in appearance was visually observed to evaluate whether or not there was a change such as white turbidity or precipitation. The compositions before storage were all colorless and transparent.
◯: There was no change.
X: There was a change.

Results Results are shown in Tables 1-3.

  As is clear from Tables 1 to 3, the compositions of Examples 1 to 24 were evaluated as ◎ or ○ in all of foaming, foaming, finger passage during rinsing, slimyness after rinsing, and low temperature stability. there were. From this, the compositions of Examples 1 to 24 are useful as liquid cleansing compositions for hair which are good in terms of foaming, foaming, finger passage during rinsing, slimyness after rinsing, and low temperature stability. I understand.

  On the other hand, unlike Examples 1 to 24, for example, the compositions of Comparative Examples 1 to 11 which do not contain any of the components (A) to (D) or have different component contents, The evaluation result was x in at least one of foaming, foam retention, finger passage during rinsing, sliminess after rinsing, and low-temperature stability, and compared with the compositions of Examples 1 to 24, a liquid for hair.
